SPIDER ENVENOMING OF DOG - CASE REPORT
Provedor de dados: 79
Autores: FERNANDES,H. S.; SAKATE,M.; CHERUBINI,A. L.; PADOVANI,A. F.; MENESES,A. M. C.
This report refers to a female Pinscher treated at the Veterinary Hospital of the Botucatu School of Veterinary Medicine and Animal Husbandry (FMVZ)-São Paulo State University (UNESP), Botucatu, 14 hours after a suspected spider envenoming. The animal showed spastic limbs, dyspnea, salivation, hypothermia, muscular fasciculation, non-responsive mydriasis, and claudication of the right hindlimb. The spider was later identified by the Center for the Study of Venoms and Venomous Animals-CEVAP/UNESP, Botucatu as Phoneutria nigriventer. The treatment with potent analgesic was efficient.

ALARM PHEROMONES AND THE INFLUENCE OF PUPAL ODOR ON THE AGGRESSIVENESS OF Polybia paulista (IHERING) (HYMENOPTERA: VESPIDAE)
Provedor de dados: 79
Autores: MANZOLI-PALMA,M.F.; GOBBI,N.; PALMA,M.S.
Field bioassays were used to demonstrate that aggressive behavior of Polybia paulista (Ihering) workers is elicited by alarm pheromones present in the venom reservoirs of nest defenders and that the brood care pheromone (pupal odor) produced by the young inside the nest also plays an important defensive role. Pupal odor was extracted from the surface of pupa bodies with methanol. When bioassayed alone, the pupal odor elicited only attractiveness of workers towards the odor source, but no stinging attacks were observed. However, in the presence of alarm pheromones, the brood care pheromone potentiated the effect caused by the pupal odors, increasing the number of stinging attacks during an action of colony defense. Thus, the presence of pupae within the...

Provedor de dados: 79
Autores: Netto,D. P.; Chiacchio,S. B.; Bicudo,P. L.; Alfieri,A. A.; Nascimento,N.
The aim of this work was to investigate antigen irradiation on crotalic antivenom and the capacity of sheep as serum producers. Twelve sheep in two groups of six were inoculated with Crotalus durissus terrificus venom. One group was inoculated with natural venom (NV) and the other with Cobalt 60 gamma-irradiated venom (IrV). Three antigen doses were given to the animals at monthly intervals for immunization. The toxic activity of the venom was assessed by LD50 determination in mice. Blood samples were collected weekly analyses of serum neutralization capacity and potency. At the end of the experiment, the animals were challenged with a LD50 for sheep showed no signs of envenoming. These results showed that toxicity of the irradiated venom was 4.4 times...

Epidemiological survey of scorpion envenomation in southwestern Morocco
Provedor de dados: 79
Autores: TOULOUN,O.; SLIMANI,T.; BOUMEZZOUGH,A.
The high frequency and severity of scorpion envenomation in Morocco is a serious public health problem, especially in semi arid and arid areas with a large rural population. In view of this alarming situation, we have conducted this investigation on scorpion envenomation in the Haouz and Souss plains between 1994 and 1998. Preliminary results have shown a high rate of scorpion envenomation with several deaths. With the exception of Scorpio maurus, the suspected species are generally anthropophilous, which belong to the Androctonus genera of the Buthidae family. The Buthidae family is responsible for 96.93% of the envenomings. In the southwestern Morocco, the death rate is of about 3.84%. The Androctonus mauretanicus is responsible for 60% of deaths. We...

Provedor de dados: 79
Autores: REMUZGO,C.; ALVAREZ,M. P.; RODRIGUEZ,E.; LAZO,F.; YARLEQUE,A.
Micrurus spixii venom was studied after fractionation by Sephadex G-100 SF gel filtration chromatography. Several enzymatic activities and biological effects were investigated in whole venom and fractions. The venom was resolved in four peaks in a range of about 73.2-10.7 kDa molecular weight. Alkaline phosphatase and acetylcholinesterase activities were found in peak I, and procoagulant activity was seen in peak II. Phospholipase A2, hemorrhagic, and proteolytic activities were detected in peak III. A second procoagulant factor and proteinase were present in peak IV. Thrombin-like enzyme and direct hemolytic activities were not found in any assayed samples.

Abscess secondary to facial snakebite
Provedor de dados: 79
Autores: QUIROGA,M.; AVILA-AGÜERO,M. L.; FAINGEZICHT,I.
In Costa Rica, approximately 700 snakebite cases occur each year, 5 to 10 of which result in death. At the Hospital Nacional de Niños (HNN), 6 to 10 cases are reported annually, more than half of these cases and nearly all deaths are result from Bothrops asper snakebite. This venomous snake, popularly known as the "terciopelo", most often attacks the lower or upper limbs and characteristically produces local tissue damage, which can be severe. The following is a report of the first case of a non-fatal and unusual facial bite caused by Bothrops asper in our country.

THE SYSTEMIC INFLAMMATORY RESPONSE SYNDROME RELATED TO THE RELEASE OF CYTOKINES FOLLOWING SEVERE ENVENOMATION
Provedor de dados: 79
Autores: VORONOV,E.; APTE,R. N.; SOFER,S.
Envenomation by insects, snakes, scorpions, and spiders involves the activation of the inflammatory system with the release and activation of pro-inflammatory cytokines, chemotactic mediators, cellular infiltration, and other vasoactive mediators. Activation of the inflammatory system and its cascade of events play a major role in the pathogenesis of envenomation, its clinical picture, and outcome. Additional clinical and laboratory studies are required to characterize the exact mechanisms by which the inflammatory system affects the pathophysiology, clinical course, and complications following envenomations. A better understanding of the involvement of the inflammatory cascade in different envenoming syndromes may have future therapeutic benefits.

The photodynamic action of UV sensitized methylene blue on the venom of Thailand cobra Naja siamensis
Provedor de dados: 79
Autores: GAWADE,S. P.
The photodynamic action of UV sensitized methylene blue (MB) was studied on the venom of Thailand cobra Naja siamensis. The reaction mixture comprising phosphate buffer (B), methylene blue (S), and venom protein (P) was exposed to UVR (ultra violet radiation) for 2 hours at 37°C. Stable excited species (S’) were generated by photodynamic action. These in B environment produced reduced substates SH2 and photooxidised products PO in the presence of atmospheric oxygen. Increased absorbance (OD) of the reaction mixture after UVR with a corresponding loss of protein was suggested to be due to the formation of photooxidised venom products. The detoxification profile of venom protein using visible radiation in the presence of MB and oxygen appeared similar to the...

AN IN VITRO STUDY OF THE EFFECTS OF VENOM OF AUSTRALIAN ELAPIDS ON MURINE SKELETAL MUSCLE AND THE PROTECTIVE EFFECT OF HOMOLOGOUS PLASMA
Provedor de dados: 79
Autores: BUTLER,T. L.; JACOBSEN,P. F.; MIRTSCHIN,P. J.; KAKULAS,B. A.
The venom of many dangerous Australian snakes has a myotoxic component and some are strongly myolytic. The myotoxicity of venom of seven Australian elapid snakes was studied to determine their relative in vitro potency in causing cell death of C2C12 cells, a myoblast cell line, and murine myotubes in mixed cell culture. The venom of Pseudechis australis proved to be the most myotoxic, Austrelaps superbus and Pseudechis porphyriacus venoms also exhibited high myotoxicity relative to the other venoms tested. The specificity of Pseudechis porphyriacus venom was tested using the human glioma cell line TC3 and was shown to exhibit a general cytotoxicity. Myotoxicity, however, was the predominant action of the venom. It has long been known that certain animals...

Worldwide occurrence of envenomation by snakebite in pregnancy is rare according to the medical literature. The objective of the present study was to evaluate the frequency of snakebite envenomation cases as well as their obstetrical consequences. Thus, we conducted this study based on the medical records of 157 patients, aged from 13 to 54 years old who had been attended at the "João de Barros Barreto" University Hospital from January 1989 to May 1994. These patients presented epidemiological and clinical diagnosis of snakebite envenomation. Of the 157 patients, 8 (5%) were pregnant, 6 of them (75%) were in the first trimester of pregnancy and 2 (25%) in the 2nd trimester. Most of the victims were usually over 18 years old (7 cases, 87.5%). Concerning the...

ANNUAL VARIATIONS OF THE SODIUM CHANNEL BLOCKING TOXIN IN VENEZUELAN CATTLE PRONE TO DEVELOP THE BOVINE PARAPLEGIC SYNDROME: ITS DEPENDENCE ON RAIN
Provedor de dados: 79
Autores: SEVCIK,C.; D'SUZE,G.
A characteristic of the bovine paraplegic syndrome (BPS) is ventral or sternal decubitus in animals that make unsuccessful efforts to stand when stimulated. Death occurs after a few days. In a previous work we showed the existence of a sodium channel blocking toxin (SCBT) produced by ruminal bacteria in cattle with or liable to develop BPS. The presence of SCBT in bovine plasma sampled monthly during the rainy and dry seasons in animals without BPS has now been observed. A positive correlation between rain precipitation and plasma toxin levels (Spearman's rank correlation coefficient=0.457, n=135, p&amp;lt;10&lt;img SRC="http:/img/fbpe/jvat/v4n1/image522.gif"&gt; ) was found.

Scorpion (Buthus tamulus) venom toxicity on cardiopulmonary reflexes involves kinins via 5-HT3 receptor subtypes
Provedor de dados: 79
Autores: BAGCHI,S.; DESHPANDE,S. B.
The mechanisms underlying the action of Indian red scorpion Buthus tamulus (BT) venom-induced augmentation of cardiopulmonary reflexes elicited by intravenous injection of 5-HT were examined in urethane anaesthetized rats. The 5-HT produced a concentration-dependent increase in time-response area of bradycardiac response, with the responses at submaximal concentrations shifted to the left after exposure to BT venom (20 µg/kg, IV). Aprotinin (6000 kallikrein inactivating unit, IV) as such had no effect on 5-HT reflex responses (bradycardia, hypotension, and apnea), but blocked the venom-induced reflex augmentation. While ondansetron (10 µg/kg, IV) completely blocked the 5-HT reflex responses, these reappeared partially after venom exposure (20 µg/kg)....

Toad envenoming in dogs: effects and treatment
Provedor de dados: 79
Autores: SAKATE,M.; OLIVEIRA,P. C. LUCAS DE.
Toads (order: Anura; family: Bufonidae; genus: Bufo) are distributed throughout the world, but more species are found in areas of tropical and humid temperate climates. Although toads do not have a venom inoculation system, they are venomous animals because the glands covering the whole surface of their bodies secrete a milk-like venom of which composition is not yet completely known. Some of these glands are the bilateral glands located in post-orbital position. These glands, which are somewhat diamond-shaped and can be seen by the naked eye, are known as parotids. Toad envenoming in dogs may cause local and systemic alterations and may cause death by cardiac ventricular fibrillation. The electrocardiographic alterations observed consist of gradual...

Convulsive effects of some isolated venom fractions of the Tityus serrulatus scorpion: behavioral, electroencephalographic, and neuropathological aspects
Provedor de dados: 79
Autores: CARVALHO,F. F.; NENCIONI,A. L. A.; LEBRUN,I.; DORCE,V. A. C.; SANDOVAL,M. R. L.
It has been previously shown that the crude venom of Tityus serrulatus can cause convulsions. This study was designed to investigate the neurotoxic effects of B, C, G, and K fractions isolated from this venom. Intravenous injection of these fractions in mice (0.6 - 6.0 mg/kg body weight) showed that the C fraction is a potent convulsant and G fraction decreased the threshold for tonic hand limb extension elicited by transauricular electroshock. Unilateral injection of B, C, and K fractions, but not G fraction, into the hippocampus of rats (0.6 - 6.0 µg) caused electroencephalographic alterations consisting of spikes and epileptic discharges that began in the hippocampus and evolved to the cortex. The following motor signs were observed: movements of facial...

OCCURRENCE OF TETRODOTOXIN AND PARALYTIC SHELLFISH TOXINS IN Phallusia nigra (TUNICATA, ASCIDIACEA) FROM THE BRAZILIAN COAST
Provedor de dados: 79
Autores: FREITAS,J. C.; OGATA,T.; VEIT,C.H.; KODAMA,M.
We have already shown the presence of guanidine neurotoxins in calcareous red algae and mussels collected in the São Sebastião channel (State of São Paulo, Brazil). It is known that these neurotoxins comprise more than 25 analogues such as tetrodotoxin (TTX) and derivatives plus the paralytic shellfish toxins (PST) found in a variety of marine, freshwater and amphibious species. Filter feeding animals generally possess large amounts of these neurotoxins. The tunicates are sessil marine animals with a high rate of sea water filtration. The tunics and siphons of 50 specimens of Phallusia nigra were dissected and the visceral organs were immersed in methanol containing acetic acid 0.02 N pH 5.0. The extract was prepared by homogenization, filtration and the...

Provedor de dados: 79
Autores: MELO,A.; MALASPINA,O.; DINIZ-FILHO,J. A. F.
In this paper we proposed to estimate the heritability of seven morphological characters that compose the sting apparatus of the Africanized honeybee workers. An experimental design to estimate genetic parameters was based on the method developed by Oldroyd and Moran(9). This method was modified to eliminate within-colony environmental effects associated with the additive genetic variance. The estimated h&lt;img SRC="http:/img/fbpe/jvat/v3n2/image1800.gif"&gt; values ranged from 0.17 ± 0.11 (maximum width of bulb of sting stylet and height of the valve of right lancet) to 0.74 ± 0.30 (length of the lancet).

Autores: EICKSTEDT,V. R. D. von; RIBEIRO,L. A.; CANDIDO,D. M.; ALBUQUERQUE,M. J.; JORGE,M. T.
Two scorpion species of medical importance occur in the state of São Paulo: the native brown scorpion Tityus bahiensis (Perty) and the highly toxic yellow scorpion Tityus serrulatus Lutz and Mello, which was brought into the state. The study of accident data of patients admitted to the Vital Brazil Hospital of the Butantan Institute from l982 to l993 revealed a gradual increase in stings by T. serrulatus in contrast to those by T. bahiensis with a variation from 5.2% to 29.7%. Also, an inventory of the scorpions sent to the Laboratory of Venomous Arthropods of the Butantan Institute over the same period showed an expressive growth in the number of T. serrulatus specimens in contrast to that of T. bahiensis. These data suggest a significative proliferation...

ABSENCE OF SEASONAL EFFECT ON THE IMMUNOMODULATORY ACTION OF BRAZILIAN PROPOLIS ON NATURAL KILLER ACTIVITY
Provedor de dados: 79
Autores: SFORCIN,J. M.; KANENO,R.; FUNARI,S. R. C.
Propolis, a beehive product widely used in folk medicine as an antiinflammatory agent, has been attracting researchers' attention to scientifically elucidate its biological properties and therapeutic activities. The aim of this paper was to study the possible effect of propolis on natural killer activity, since propolis immunomodulatory action has been suggested, especially on non-specific immunity. Propolis was produced by africanized honeybees (Apis mellifera L.), collected throughout a whole year, and pooled by season. Hydroalcoholic solutions of propolis were prepared with each pool and administered to rats by gavage over three days. Natural killer activity of non-adherent spleen cells was evaluated by the 51Cr-release cytotoxicity assay against Yac-1...

Autores: HAMPE,O. G.; BELLÓ,A. A.
very sensitive method for estimating the concentration of crotamine in a solution was developed. This method was based on the time required for the appearance of permanent hyperextension of the rear legs of mice as a function of the dose administered. This method can be used to determine toxin doses as low as 0.32 mg/kg&lt;img SRC="http:/img/fbpe/jvat/v3n1/image2875.gif"&gt; . Its high specificity for crotamine means that it can be used to measure toxin concentrations in the presence of other proteins and polypeptides.

VIPER ENVENOMING: EVALUATION OF TREATMENT BY RESTORATION OF HAEMOSTASIS AND VENOM CLEARANCE
Provedor de dados: 79
Autores: THEAKSTON,R. D. G.; KAMIGUTI,A. S.
Treatment of systemic envenoming in snakebite victims has, in the past, depended almost entirely on the individual clinician's experience in assessing the severity of envenoming. The efficacy of treatment is obviously related to the neutralising potency of the antivenom used, the route by which it is administered and the dose. The use of techniques for evaluating the efficacy of antivenoms has proved to be very useful, as an adjunct to recognised clinical observations, for a more objective evaluation of antivenom efficacy and dosage. In patients bitten by many vipers, including the Brazilian pit vipers, the reversal of the venom-induced coagulopathy provides an ideal indicator as to the efficacy of an antivenom. Likewise, the development of enzyme...

Provedor de dados: 79
Autores: LIPPS,B. V.
Currently, the use of antivenoms is the only available treatment for envenomation caused by venomous animals namely, snake, scorpion, spider, tick and jelly fish. Antivenoms are generally produced in large animals, mostly in horses. A large percentage of the population is allergic to horse proteins. Several animals are known to be resistant to snakebites and the antihemorrhagic and anti-lethal components have been isolated from sera of opossum, mongoose, meerkat and hedgehog, as well as from venomous and non-venomous snakes. Anti-lethal factor named Lethal Toxin Neutralizing Factor (LTNF) has been isolated in purity from opossum (Didelphis virginiana) serum by high pressure liquid chromatography (HPLC). The molecular weight of LTNF is 63 kDa, and it does...

EFFECTS OF SCORPION Tityus serrulatus VENOM TOXIN TS-8F ON RAT LEARNING AND MEMORY
Provedor de dados: 79
Autores: MARUO,V. M.; LEBRUN,I.; DORCE,V. A. C.
Scorpion venom neurotoxins are responsible for toxicity and pharmacological effects. They are active in sodium and potassium channels leading to an increase in the release of neurotransmitters, such as glutamate. Glutamate is found in large quantities in the hippocampus (HPC) and is involved in the long-term potentiation (LTP) induction. The HPC is known to be related to certain kinds of memory. The aim of this study is to evaluate the effects of Tityus serrulatus TS-8F toxin on rat behavior with emphasis on learning and memory. We analyzed the effects of different doses of TS-8F on rat behavior in home cages, open-field (habituation), inhibitory avoidance, T-maze, and hippocampus morphology. In the first two experiments, 0.05µg/animal dose of TS-8F did...

Since primeval times, the inflammatory process has been described in many different ways. Several anti-inflammatory therapies have been used in different biological models. However, in a recent "back to nature move", modern man is searching for natural products with medicinal properties, particularly those obtained from plants and bees. Propolis has been used in folk medicine for a very long time. The many compounds present in propolis require investigation.Physical-chemical analysis studies have not sufficiently established quality standards of propolis containing products. These standards should depend especially on their different pharmacological activities. There are few studies reporting on the in vitro anti-inflammatory activity of propolis...

The presence of a polydnavirus in the ovary of the microhymenoptera Apanteles galleriae was detected. This wasp parasites the larvae of the wax moth Galleria mellonella. To study the possible viral effects on the total protein of G.mellonella, hemolymph extracts of the ovary calyxes of parasitized A. galleriae were injected into 6th and 7th instar cells of G.mellonella larvae. Protein profiles on polyacrilamide gel electrophoresis containing sodium dodecyl sulfate (SDS-PAGE) of host cell extracts showed a suppression of several protein bands when infection occurred in the 6th instar. However, in the 7th instar, parasitism caused an amplification in the synthesis of most proteins with some changes in the electrophoretic profile.

Venomous snakebites in children and adolescents: a 12-year retrospective review
Provedor de dados: 79
Autores: AVILA-AGÜERO,M. L.; VALVERDE,K.; GUTIÉRREZ,J.; PARÍS,M. M.; FAINGEZICHT,I.
Snakebite envenomation is a worldwide problem and in Costa Rica. The following is a retrospective review of 79 patients admitted to the Hospital Nacional de Niños (HNN) from January 1985 to September 1996. Child's age ranged from 9 months to 14 years. The M: F ratio was 1.5:1. Sixty percent of the patients lived in remote rural areas. The most common clinical signs at the time of hospitalization were pain and edema.

The scorpion envenoming syndrome: a different perspective. The physiological basis of the role of insulin in scorpion envenoming
Provedor de dados: 79
Autores: MURTHY,K. R. KRISHNA.
Death caused by scorpion envenoming (Buthidae family) is a common event in tropical and subtropical countries. Severe scorpion envenoming causes an autonomic storm resulting in a massive release of catecholamines, angiotensin II, glucagon, cortisol, and changes in insulin secretion. As a consequence of these changes in the hormonal milieu, scorpion envenoming results in a syndrome of fuel energy deficits and an inability of the vital organs to utilize the existing metabolic substrates, which causes myocardial damage, cardiovascular disturbances, peripheral circulatory failure, pulmonary oedema, and many other clinical manifestations alone or in combination, producing multi-system-organ-failure (MSOF) and death. Insulin-glucose infusion or antivenom...

DETOXIFICATION OF SNAKE VENOM USING IONIZING RADIATION
Provedor de dados: 79
Autores: ROGERO,J.R.; NASCIMENTO,N.
It is generally recognized that energy absorbed from ionizing radiation (gamma rays) can inactivate biological material in two ways. A direct effect occurs when the primary event, i. e., ionization, is produced in the molecule itself. This is the case when a compound is irradiated in dry state. When a compound is irradiated in a solution, the indirect effect joins the direct(9). Since water is the most abundant constituent of biological material, it is important to consider the species produced by excitation and ionization of water itself, and the reaction of these species with the target molecules of biological importance. This indirect effect results from the reactions among the studied molecules and the products of radiation interaction with water or...

SERUM BIOCHEMICAL DETERMINATIONS OF PROPOLIS-TREATED RATS
Provedor de dados: 79
Autores: SFORCIN,J.M.; FUNARI,S.R.C.; NOVELLI,E.L.B.
Ethanolic extracts of the bee glue, a resinous substance collected by honeybees called propolis, have been widely used in folk medicine since ancient times. Antibacterial, antifungal and thus antiseptic properties may represent the basis for the historical and present use of these extracts in dermatology, against inflammatory conditions and common colds. This work was carried out in order to verify possible biochemical alterations in some seric parameters of propolis-treated rats. It was shown that propolis possesses an antioxidant property and its administration did not affect either amylase and alanine transaminase activities or total protein concentration.

Recently, propolis has been attracting the attention of researchers due to various biological activities and therapeutic properties. In Brazil, propolis is produced all year long, so there may be some seasonal variations. This work was carried out in order to compare propolis collected during the four seasons by its in vitro antimicrobial activity on yeast pathogens isolated from human infections. Propolis was produced by africanized honeybees in Botucatu, São Paulo State, collected throughout a year and pooled by season. Hydroalcoholic solutions of propolis were prepared with each pool and diluted in agar, using serial concentrations of propolis from each pool. A determination of minimal inhibitory concentration (MIC) was performed. The results show that...

Propolis has been the subject of several recent studies, with the aim of elucidating its biological and pharmacological properties. Propolis has a well-known antimicrobial activity as well as antioxidant, antitumoral, antiinflammatory, and regenerative properties, but literature about its effects on the immune response is scarce. The goal of this work was to evaluate the propolis effect on macrophage activation by oxygen (H2O2) and nitrogen (NO) metabolite determination. Propolis was produced by africanized honeybees and hydroalcoholic solutions were prepared at different concentrations. Peritoneal macrophages were obtained from male BALB/c mice and culture cells were stimulated in vitro with propolis or interferon-gamma (IFN-gamma). In the in vivo assay,...

Scorpion envenoming is a public health concern in northeastern Venezuela. Specimens of the genus Tityus are responsible for most of these. In experimental animals, Tityus venom produces histopathological changes in the skeletal muscle and pancreas, but its toxicity to the reproductive system has not been studied. The aim of this work is to describe the histopathological changes in testis and epididymis of albino mice induced by the administration of Tityus n. sp. venom. Sub-lethal doses of venom (3.75 mg/g mouse) were administered intramuscularly (IM) daily for 4 days. On the fifth day, the animals were sacrificed and the testes and epididymes were quickly removed and processed for light microscopy. The venom induced alterations in spermatogenesis. Sertoli...

LINAMARIN: THE TOXIC COMPOUND OF CASSAVA
Provedor de dados: 79
Autores: CEREDA,M. P.; MATTOS,M.C.Y.
Cassava is a widely grown root crop which accumulates two cyanogenic glucosides, linamarin and lotaustralin. Linamarin accounts for more than 80% of the cassava cyanogenic glucosides. It is a ß-glucoside of acetone cyanohydrin and ethyl-methyl-ketone-cyanohydrin. Linamarin ß-linkage can only be broken under high pressure, high temperature and use of mineral acids, while its enzymatic break occurs easily. Linamarase, an endogenous cassava enzyme, can break this ß-linkage. The enzymatic reaction occurs under optimum conditions at 25ºC, at pH 5.5 to 6.0. Linamarin is present in all parts of the cassava plant, being more concentrated on the root and leaves. If the enzyme and substrate are joined, a good detoxification can occur. All the cassava plant species...

Cardioleputin, a new cardioactive toxin, was purified from a stonefish venom using column chromatographies. The purified toxin was found to be an unstable protein that was susceptible to heat and freeze-thawing. This protein showed to have a molecular size of 46,000 daltons, and its amino acid composition was rich in serine and glycine, but low in basic amino acids. The crude venom induced a sudden drop in blood pressure and heart rate of rats right after administration. Both the blood pressure and heart rate returned to their original values as time elapsed, and thereafter continued to show a gradual decrease. In addition, crude venom actively affected the contractile response and suppressed the heart rate of guinea pig atria. The purified toxin caused...

The present investigation reveals the possibility of simultaneous immunization of horses with Bothrops or Crotalus snake venoms and Tetanus antigens for the production of anti-Bothrops-Tetanus or anti-Crotalus-Tetanus mixed serum, with high titers of the respective specific antibodies. Bothrops antivenoms with an average neutralizing titer of 4.16 mg venom/ml were obtained from plasma of horses with titers lower than 0.5 mg venom/ml when Tetanus antigens were not used. This suggests the existence of a synergism between Bothrops venoms and Tetanus antigens in the stimulation of the antibody response.

PURIFICATION AND CHARACTERIZATION OF TOXINS FROM WHEAT ISOLATES OF Drechslera tritici-repentis, Bipolaris bicolor, AND Bipolaris sorokiniana
Provedor de dados: 79
Autores: BACH,E. E.; KIMATI,H.
Low molecular weight metabolites produced by Bipolaris bicolor, Bipolaris sorokiniana, and Drechslera tritici-repentis are considered to be toxins that facilitate disease in wheat cultivars. Several such toxins were isolated from these fungi. Electrophoresis demonstrated bands of proteins that reduced shoot inhibition in susceptible plants but not in resistant plants. Chlorophyll content was reduced during the first 10 hours of light in the susceptible plants and after 18 hours in the resistant plants. The enzyme beta-1,3-glucanase increased in the resistant plants after treatment with toxins, but in the susceptible plants this enzyme decreased compared to the control. This suggests that the toxin was a protein and the susceptible plants needed other...

Bothrops jararacussu venom and its major toxin bothropstoxin-I (BthTX-I) possess myotoxic and neurotoxic properties. The efficacy of a rabbit antivenom raised against B. jararacussu venom in the neutralization of physiological, biochemical, and morphological changes induced by the venom and its major toxin BthTX-I was studied in mouse isolated phrenic nerve-diaphragm (PND) and extensor digitorum longus (EDL) preparations. The times required for 50% neuromuscular blockade in PND and EDL preparations for venom were 70+11.5 (S.E.M., n=5) min and 58+8 (n=16) (50 mu g/mL), and for BthTX-I 31+6 (n=3) min and 30+3 (n=5) min (20 mu g/mL), respectively. After 120 min incubation, creatine kinase (CK) concentrations in solution containing the EDL preparations were...

Sequelae due to testicular biopsy such as hemorrhage, adhesion and fibrosis may be limiting factors to the use of this surgical procedure. Fibrin glue (FG) derived from snake venom was used to minimize these sequelae, as well as to evaluate its healing property in tunica vaginalis and scrotal skin of rams. Applicability of fibrin glue derived from snake venom was tested in different tissues of other animals such as in sciatic nerve and colon of rats and skin of rabbits. In the present study, 30 healthy adult rams were used. They were divided into 3 groups of 10 animals each as follows: G1: fibrin glue group (application of fibrin glue on puncture sites and skin incisions after bilateral testicular biopsy with a Tru-Cut needle); G2: swab/nylon group...

Autores: FRANCO,R. L.; ROCHA,C. C.; JORGE,M. T.; RIBEIRO,L.A.
In Brazil, more than 80% of venomous snakebites are caused by Bothrops and about 10% by Crotalus. This study evaluated 133 reported cases that occurred between 1994 and 1996 in the 52 municipalities covered by the Pouso Alegre Regional Health Center in southern Minas Gerais State. Most of the patients were male (89.5%). The most frequently attacked age bracket was that of people in their twenties, and the most frequently bitten anatomical regions were the lower limbs (77.7%), principally the feet (34.6%). Of the 124 cases stating the snake genus, 62.9% were caused by Crotalus and 37.1% by Bothrops. The conclusion of this study is that although the epidemiology of snakebites in Minas Gerais State is similar to other regions of the country, the percentage of...

Autores: DE SOUSA,L.; PARRILLA-ALVAREZ,P.; QUIROGA,M.
In Venezuela, the restricted manner of works on scorpion envenoming has contributed little to the real magnitude and knowledge of this subject in our country. The lack of basic scorpiofauna knowledge, distribution, clinical manifestations, and especially of specific treatments justify multidisciplinary studies. The purpose of these studies is to obtain information that allows the elaboration of a preventive plan. This paper demonstrates the magnitude of scorpion envenomings in Venezuela.

Provedor de dados: 79
Autores: STANILOVA,S.; ZHELEV,Z.; MATEV,I.
The present study demonstrates that Vipera ammodytes venom is a potent inhibitor of human complement activation. Crude venom was fractionated by ion-exchange chromatography and each fraction was then tested for proteolytic, hemolytic and anti-complement activities. Three peaks decreased the hemolytic activity of human serum when measured using assays for the classical and alternative pathways of activation. One of the anti-complement peaks contains a protease capable of cleaving the C3 component of complement.

Major clinical signs were depression, vomiting, abdominal pain, weakness, recumbency, paddling convulsions terminating in death from 6 to 96 hours after ingestion. Gross pathological findings included ascites with fibrin strands, enlarged, congested and friable livers with accentuation of lobulation on the capsule. Microscopically, acute hepatic congestion and hemorrhage, centrilobular hepatocyte necrosis, with occasional binucleation together with discoid lysis of skeletal and cardiac muscle fibers were remarkable changes. Binucleation of hepatocytes and degenerative changes in active muscles have not been reported before in relation to cocklebur plant toxicosis. These findings suggest that X. strumarium is a potential cause of sudden death in pigs...

Some properties of a Africanized honeybee venom proteases were determined by enzymatic assays in solution, electrophoresis in SDS-PAGE, and gel filtration. Bee venom extracts were obtained by reservoir disruption, selective dialysis (cut off 12 kDa) to eliminate small components, such as the protease inhibitor present in the venom, and then fractionation of the dialyzed extract by gel filtration on a Sephadex G-100 column. The optimal conditions for the caseinolytic assays were pH 9.5, 2-hour digestion at 37 °C, and 1% casein concentration. The proteolytic activity was also determined by electrophoresis in SDS-PAGE with co-polymerized gelatin with three major bands of 66.0, 41.6, and 25.1 kDa. A principal serine-protease-like mechanism was revealed in the...

Phospholipase A2 (PLA2), a component of most snake venom toxins, cleaves 3-sn-phosphoglycerides releasing lysophosphatidyl-choline. The indirect quantitative assay method for PLA2 was standardized for specific antivenom titration in a fast and sensitive assay by the similarity with the hemolysis induced by PLA2 and by complement system in sheep erythrocytes. The curves obtained by plotting the degree of hemolysis against the doses of snake venom are concave to the abscissa axis following an equation similar to that previously described for the hemolysis induced by the C system.

INFECTIONS IN THE BITE SITE AFTER ENVENOMING  BY SNAKES OF THE Bothrops GENUS
Provedor de dados: 79
Autores: JORGE,M. T.; RIBEIRO,L. A.
Envenomation caused by snakes of the Bothrops genus produces a lesion in the bite site and can result in extensive necrosis. The dead tissue can be secondarily infected by bacteria that come from the snake, and the bacteria can be inoculated at the moment of the bite. The bacteria that most commonly cause infection are the enterobacteria, mainly Morganella morganii, Proteus rettgeri, Enterobacter sp., and Escherichia coli. Group D streptococci including here Enterococcus sp. and the Bacteroides sp. are also involved. Based on a study of the sensibility of these bacteria, it has been suggested that this infection must be treated with chloramphenicol, as a sole antimicrobial agent, or with the combinations of benzylpenicillin or ampicillin with...

Fibrin glue has been used on its own or in conjunction with suturing materials to promote hemostasis, reduce adherence, strengthen the wound site, and improve healing. Snake venom derived fibrin glue was evaluated as an alternative to conventional uterine suturing after ovine caesarean surgery. Twenty-eight pregnant ewes of known mating date were used. The animals submitted to conventional caesarean sections showed a better wound healing process. As expected, all the operated animals had retained placenta, compromising coaptation of wound edges. This had a strong influence in the results observed with the animals in which fibrin glue was used. The animals were divided into four groups GI, GII, GIII, and GIV and sacrificed, respectively, 3, 7, 15, and 30...

METHODOLOGICAL CARE IN THE EVALUATION OF THE LD50 AND OF THE NEUTRALIZATION OF THE LETHAL EFFECT OF Crotalus durissus terrificus VENOM BY THE PLANT Peschiera fuchsiaefolia (APOCYNACEAE)
Provedor de dados: 79
Autores: BATINA,M. de F. C.; GIGLIO,J. R.; SAMPAIO,S. V.
In the present study, we demonstrate that the volumes in which a given protein mass of Crotalus durissus terrificus venom or of a lyophilized stabilized aqueous extract (LSAE) of Peschiera fuchsiaefolia, an antivenom agent injected intramuscularly, have a decisive influence on the results. The LD50 of C. d. terrificus venom injected i.m. in a final volume of 200µl (2µl/g) (saline solution, 0.9% NaCl) was 180µg/100g rat body weight (p&amp;lt;0.05, 161 to 202µg/100g body weight) and the LD50 of the venom injected i.m. in a volume of 50µl (0.5µl/g) was 120µg/100g body weight (p&amp;lt;0.05, 107 to 134 µg/100g body weight). The reduction of the final volume injected i.m. also required a reduced mass of LSAE necessary to neutralize the lethal effect of C. d....

RADIOPROTECTION: MECHANISMS AND RADIOPROTECTIVE AGENTS INCLUDING HONEYBEE VENOM
Provedor de dados: 79
Autores: VARANDA,E. A.; TAVARES,D. C.
Since 1949, a great deal of research has been carried out on the radioprotective action of chemical substances. These substances have shown to reduce mortality when administered to animals prior to exposure to a lethal dose of radiation. This fact is of considerable importance since it permits reduction of radiation-induced damage and provides prophylactic treatment for the damaging effects produced by radiotherapy. The following radioprotection mechanisms were proposed: free radical scavenger, repair by hydrogen donation to target molecules, formation of mixed disulfides, delay of cellular division and induction of hypoxia in the tissues. Radioprotective agents have been divided into four major groups: the thiol compounds, other sulfur compounds,...

TOXIC SHOCK SYNDROME
Provedor de dados: 79
Autores: BERGDOLL,M. S.
Toxic shock syndrome is a staphylococcal disease caused by toxins produced by the staphylococci, toxic shock syndrome toxin-1 and enterotoxin B. The disease results from staphylococci growing in the vagina with the use of tampons during menstruation, primarily in young women. However, any staphylococcal infection can result in toxic shock syndrome if the staphylococci produce the appropriate toxins and the individual has no antibodies to the toxins. The symptoms can be quite severe, with high fever, low blood pressure, diffuse macular erythroderma, orthostatic dizziness, vomiting and or diarrhea at the onset, severe myalgia, peeling of the skin of the palms of the hands and the soles of the feet after seven to ten days, and death in some cases. The disease...

Histological aspects and protein content of Apis mellifera L. Worker venom glands: the effect of electrical shocks in summer and winter
Provedor de dados: 79
Autores: ABREU,R.M.M.; MORAES,R.L.M. SILVA de; MALASPINA,O.
This paper analyzes the summer and winter total protein content of 7, 14, 21, 28, 35, and 40-day old Apis mellifera L. worker venom glands before (control) and 24 and 96 hours after applying electrical shocks for venom extraction (experimental). During venom extraction, 7-day old workers responded more slowly and weakly to electrical shocks. This response intensifies with age, so that the workers approaching 20 days old respond faster and more aggressively to the shocks. Statistical analysis, using the non-parametric Wilcoxon and Kruskall-Wallis tests and complemented by the Jonckheere test, showed that the protein content varied from one age to another in the experimental group, which was well distinguishable from the values in the control Group in summer...

Susceptibility to several ethanolic extracts of propolis (EEP) concentrations was tested with the population analysis technique in reference strains of Staphylococcus aureus (ATCC 25923) and Escherichia coli (ATCC 35218). The results of these tests showed that all bacteria were killed by EEP concentrations approximately equal or higher (2.0% v/v- S. aureus; 10.0% v/v - E. coli) than the respective minimal inhibitory concentrations (MIC). Regarding the susceptibility to propolis, there was a homogeneity of data with the respective time kill curves showing a clear bactericidal effect during 6 to 9 h of exposition.

The presence of pharmacological substances myoglobin and histamine in venoms
Provedor de dados: 79
Autores: LIPPS,B. V.; KHAN,A. A.
It is well documented that several pharmacological substances are released within the victim's body after snakebite. These substances are also believed to be endogenously present in animals, specifically levels of myoglobin and histamine that are reported to rise after envenomation. However, there is no published data regarding the presence of these substances in venoms per se. This research reports the detection of myoglobin and histamine in snake, scorpion, honeybee, and toad venoms by immunological test. It is unlikely that the rise in levels of myoglobin and histamine is due to that added from the bite, since a single toxin devoid of such components is capable of elevating levels of these substances. Nonetheless, it is likely that the rise in levels of...

Lethal Toxin Neutralizing Factor (N-LTNF), MW 63.0 kDa, was isolated from opossum serum. After trypsin digestion, the active domain of N-LTNF was isolated and sequenced. The synthetic peptide consisting of ten amino acids was designated as LT-10. N-LTNF and LT-10 inhibited the lethality of animal, plant and bacteria toxins when tested on mice non-immunologically. The antibodies against N-LTNF and LT-10 only reacted immunologically with toxins and not with non-toxic substances. Anti-LTNF and anti-LT-10 reacted immunologically by ELISA test with toxins that were not detected by mouse test, such as cholera toxin and digoxin. Anti-LTNF and anti-LT-10 failed to react immunologically with non-toxic substances, such as nerve growth factor and collagen. Currently,...

The first antivenom was prepared by Calmette in 1894. More than a century later, it is still the only specific treatment for envenoming. The methods currently used by almost all antivenom producers worldwide to isolate and concentrate antivenom antibodies and their enzymatically derived fragments are improvements of those originally developed by Pope in 1938. Several new alternatives have been proposed to produce F(ab')2 or Fab antivenoms to improve their purity, neutralizing potency, and safety and to overcome the problems encountered in the production protocols based on ammonium sulfate precipitation of equine immunoglobulin. These include complete or partial modifications in the antivenom production regarding animal producers (ovine, laying hens...),...

Lethal Toxin Neutralizing Factor (LTNF), isolated from opossum with having molecular weight 63 kDa, is a potent antidote for animal, plant, and bacterial toxins. This communication deals with the identification of a small fragment of LTNF eliciting the anti-lethal activity of animal, plant, and bacterial toxins when tested in mice. Purified LTNF was treated with trypsin to cause fragmentation at the arginine and lysine sites. The fragments were separated by high-performance liquid chromatography (HPLC) and were tested against anti-LTNF for binding affinity by enzyme-linked immunosorbent test (ELISA). The fragment showing the most binding to anti-LTNF was sequenced. Synthetic peptides consisting of 15 and 10 amino acids from the N-terminal were constructed...

EFFECTS OF THREE FRACTIONS OBTAINED FROM Naja haje  VENOM ON HEMOLYSIS AND LIPID METABOLISM IN RABBITS
Provedor de dados: 79
Autores: EL-AAL,A. A.; EZZAT,A. R.
Three fractions (F1, F2 and F3) were obtained from the venom of the Egyptian cobra Naja haje by gel filtration. F1 and F2 had indirect hemolytic effects on rabbit erythrocytes. The HU50 (the amount of the fraction causing 50% hemolysis ) values of F1 and F2 were 12.04 ± 3.89 and 36.57 ± 2.20 µg, respectively. The effects of the three cobra venom fractions on lipid metabolism were studied after 1, 2, 3 and 4 hours. Serum total lipids and cholesterol were significantly decreased at almost all tested times, but variable changes were observed in the serum triglycerides. Serum inorganic phosphorus levels were significantly increased with F1 and F2 administration more than that with the F3 fraction. These results suggest that F1 and F2 possess phospholipase...

Autores: MURUGESAN,S.; RADHA KRISHNA MURTHY,K.; NORONHA,O. P. D.; SAMUEL,A. M.
Labelling of scorpion (Mesobuthus tamulus concanesis Pocock) venom was successfully achieved with Tc 99m using direct tin reduction procedure. Biodistribution studies were carried out in Wistar rats at different time intervals after i.v. administration of the labelled venom. Scintiimages were obtained after scorpion envenoming using a large field of view gamma camera to ascertain the pharmacological action of venom in the body. Within 5 min of administration, labelled venom was found in the blood (27.7%), muscle (30.11%), bone (13.3%), kidneys (11.5%), liver (10.4%), and other organs. The level of venom in the kidneys was higher than in the liver. The labelled venom was excreted through renal and hepatobiliary pathways. An immunoreactivity study was...

The profiles of high-performance gel filtration of venoms from Polybia paulista, Polybia ignobilis and Polybia occidentalis occidentalis showed 13 peaks distributed among the three species. These profiles presented similarities that permitted the chromatographic characterization of the genus Polybia and differences that permitted the identification of each species studied. Thus, the comparative analysis of chromatographic profiles of high-performance gel filtration of venoms may be used as an auxiliary tool in taxonomic studies of Polybia wasps.

Venezuelan arachnids: two new species of the Tityus genus (scorpionida: buthidae) and the chromatographic profile of venom as a possible taxonomical tool
Provedor de dados: 79
Autores: GONZALEZ-SPONGA,M. A.; D'SUZE,G.; SEVCIK,C.
Two new species of the Tityus genus are described. T. isabelceciliae n. sp lives on the northern central slope of the Cordillera de la Costa. It belongs to the discrepans group and is dangerous to man due to its high number, aggressive behavior, domiciliary habits, and high toxicity of its venom. T. isabelceciliae venom is similar to other Tityus in relation to the molecular weight range and the biological activity of its components. However, the proportions of each fraction in the venom pooled from many T. isabelceciliae differ from the proportions in other Tityus, indicating that these proportions may have a taxonomical value. The venom LD50 is 38.1 (36.3, 39.9) µg/g mouse (Death in 30 min, Dixon and Mood (14) sequential method, median and 95% confidence...

Goat spermatozoa were incubated in vitro in Tris-citrate buffer, pH 7.2, containing 0, 40, 80, or 160 mug of Naja haje venom/mL buffer for 4 hours. During incubation, the percentages of sperm motility were decreased, while percentages of dead spermatozoa were increased in a time and concentration-dependent manner. The effect of venom concentrations on the ultrastructure of incubated spermatozoa was examined hourly by scanning (SEM) and transmission (TEM) electron microscopy. SEM results showed plasma membrane wrinkling at heads of some spermatozoa after 2 h incubation with 40mug venom. Most spermatozoa suffered membrane wrinkling after 4 h incubation. However, incubation with 80 mug venom caused membrane fractures in most sperm heads after 1 h incubation....

In vitro toxicity assays were performed using Duvernoy's gland secretions from the African boomslang, Dispholidus typus, and isolated rat duodenum and frog sciatic nerve-gastrocnemius muscle preparations. The Duvernoy's gland secretions of D. typus had no apparent effect on the frog sciatic nerve-gastrocnemius muscle preparation. The secretions produced an increase in baseline tonus and an increase in the rhythmic contractile force of the rat duodenum, but had no significant effect on the frequency of contractions. Atropine sulfate (10&lt;img SRC="Image2369.gif" WIDTH="12" HEIGHT="12"&gt; M) effectively antagonized the excitatory effects of the Duvernoy's gland secretions at concentrations 200 µg/ml.

Aurelia aurita is a scyphozoan, abundant in the Mexican Caribbean during summer. Although usually innocuous, there is evidence of it causing harm to humans. This work investigates the biological activities of crude and fractionated extracts of A. aurita. Live specimens were collected between July and September 1999 from the Mexican Caribbean. The tentacular margin was dissected immediately and frozen at -50ºC. A nematocyst suspension was prepared, discharged, and the supernatants lyophilized. Hemolytic assay was performed with lyophilized crude extract on bovine, sheep, and human red blood cells. Erythrocyte sensitivity to the toxin was ranked in descending order: human, sheep, and bovine. Toxic activity on Artemia nauplii was evaluated using the same...

Snake venoms frequently vary in composition. In this work, we compared the neurotoxic and myotoxic activities of 16 lots of Bothrops neuwiedii venoms from different regions of Brazil, using chick biventer cervicis preparations. The neuromuscular blockade varied from 2% to 100% after 120 min incubation with venoms (50 mug/ml). In all cases, this blockade was irreversible and concentration-dependent; at low concentrations (10-20 mug/ml), 15 of the 16 venom lots failed to abolish responses to acetylcholine (110 muM), but blocked responses to KCl (13.4 muM), and induced contracture. At 5-20 mug/ml, the most active venom totally blocked twitch-tension without affecting responses to acetylcholine and KCl. Polyacrylamide gel electrophoresis for basic proteins...

THE BLOOD LEVELS OF GLUCAGON, CORTISOL, AND INSULIN FOLLOWING THE INJECTION OF VENOM BY THE SCORPION (Mesobuthus tamulus concanesis, POCOCK) IN DOGS
Provedor de dados: 79
Autores: RADHA KRISHNA MURTHY,K.; HAGHNAZARI,L.
Severe envenoming was induced in two groups of experimental dogs after subcutaneous (SQ) injection of venom of the scorpion (Mesobuthus tamulus concanesis, Pocock) (3.0 and 3.5 mg/kg body weight). The circulating levels of blood sugar, insulin, glucagon, and cortisol were assayed at 0, and 30, 60, 90 and 120 min after venom injection. There was an increase in the circulating levels of blood sugar, insulin, glucagon, and cortisol following envenoming. Scorpion envenoming causes an autonomic storm resulting in a massive release of catecholamines, angiotensin II, glucagon, and cortisol accompanied by changes in insulin secretion. The rise in the counter-regulatory hormones (glucagon, cortisol, and catecholamines) oppose the anabolic actions of insulin...

Autores: GONZALES-SPONGA,M. A.
Two new scorpion species of the Buthidae family, Tityus ivic-nancor and Tityus sanarensis, are described in this paper. Both species belong to the "androcottoides" group and live from 1300 to 1400 m. above sea level near the town of Sanare (69º42'17.8"W, 9º45'3.9"N) in the southern part of the state of Lara in Venezuela. The number of Tityus species already known in Venezuela increases to 28 with the inclusion of these two new species. This paper includes a descriptive diagnosis and also a differential diagnosis of the species of Tityus that are geographically related to T. ivic-nancor and T. sanarensis. Drawings of the significant morphological characteristics of male and female specimens and a morphometric table are also included.

Use of lidocaine, propranolol, amiodarone, and verapamil in toad envenoming (genus bufo) in dogs
Provedor de dados: 79
Autores: SAKATE,M.; OLIVEIRA,P. C. LUCAS DE.
Toad envenoming in dogs can cause death by cardiac fibrilation (CVF). Traditional therapy consists mainly of atropine and propranolol, the last one used to prevent the CVF, that is preceded by negative ventricular deflections (NVDs) in the QRS complex of the electrocardiogram. This study intended to verify, comparatively, the lidocaine, propranolol, amiodarone, and verapamil abilities to prevent CVF in experimentally envenomed dogs. Thirty-six dogs were divided into 6 groups (GL, GP, GA, GV, GST, and GSV) with n=6; the dogs were submitted to volatile anaesthesia. The animals of the groups GL, GP, GA, and GV received 0.38g of toad venom through oro-gastric catheter and were treated with the following drugs respectively: lidocaine (4mg/Kg), propranolol...

Neuromuscular blocking action of the Theraphosa blondii spider venom
Provedor de dados: 79
Autores: Fontana,M. D.; Lucas,H. S. M.; Vital Brazil,O.
In 1919, Houssay and Negrete reported that venoms of Theraphosidae spiders induced neuromuscular blockade. In 1993, a purified toxin from Grammostola spider venom was found to block the P-type voltage-dependent calcium channel (VDCC), causing neuromuscular blockade. We studied the mode of action of Theraphosa blondii venom, a large Theraphosidae spider from Northern Brazil, Venezuela, and The Guyanas in mouse phrenic nerve-diaphragm preparation. This venom elicited a partially reversible neuromuscular blockade and did not depress directly evoked twitches or alter the membrane potential. Neostigmine produced only a poor antagonistic effect on partially blocked diaphragms. However, completely blocked miniature endplate potentials (m.e.p.ps) were reverted by...

Honey, royal jelly, propolis, materials produced and/or gathered by Apis mellifera honeybees have been used as food and medication for centuries(6,7,8). Although extensively used, honeybee products have become a matter of interest and controversy for years. Honey, well known as healthy and natural food, has shown therapeutic properties in the treatment of digestive, respiratory, cardiac and rheumatic disorders, among others(4). Several studies have reported honey's immunological, antibacterial, antiinflammatory, antipyretic properties besides its importance in terms of energy intake(3,5). Furthermore, honey has proved to possesses wound healing and analgesic actions(1,2). Honey and propolis are also known to be effective in the treatment of respiratory...

A comparison among the profiles of molecular exclusion chromatography in Sephadex G 100 column of venoms from Apis mellifera adansonii and Africanized honeybees revealed unique peaks which might be used to identify these populations. The venoms from hybrid populations resulting from the reciprocal mating of Apis mellifera adansonii and Africanized honeybees presented unique peaks, probably resulting from a synergistic effect between the parental genomes. The occurrence of characteristic peaks in venoms of hybrid populations might be used to identify these populations as well as to distinguish them from their parents.

A sandwich-type ELISA technique for specific and sensitive detection of Crotalus durissus terrificus venom antigens, horse-antivenom, human IgG and IgM antibodies was set up. Sixteen patients, 13 males and 3 females aged between 13 to 63 years (mean 33 ± 15) bitten by Crotalus durissus terrificus snakes were studied. Of the 15 patients, 6 had previously received anti-Crotalus venom and no seric venom was detected. For the other 9 patients studied, the venom levels ranged from 2 to 108 ng/ml according to the severity of each case. Seric antivenom was detected up to 44 days after the bite. IgM human antibody levels against Crotalus venom were higher between 3 and 18 days after specific treatment. IgG human antibody levels against Crotalus venom were detected...

Autores: SFORCIN,J. M.; NOVELLI,E. L. B.; FUNARI,S. R. C.
Propolis has been the subject of recent scientific investigation due to its biological properties, such as antibiotic, antiinflammatory, anesthetic, healing, immunomodulatory, antioxidant, and carcinostatic. The purpose of this study was to analyze the biochemical profile of propolis-treated rats to observe whether propolis might lead to side effects after administration. Evaluation of total protein, glucose, urea, creatinine, triglycerides, cholesterol, and HDL-cholesterol concentrations and determination of aminotransferases (AST and ALT) and lactic dehydrogenase (LDH) in propolis-treated rat serum were performed. The seasonal effect on propolis activity was also analyzed, considering the biochemical variables evaluated. The lack of clinically important...

Autores: MADY,E. A.
The search for snake venom antitumor efficacy has attracted the interest of scientists since the beginning of last century. Snake venom possesses a wide spectrum of biological activities. In this study, we evaluated the effect of Echis coloratus crude venom on the evolution of Ehrlich ascites carcinoma cells (EAC). Normal and EAC-bearing mice were treated with 0.2 mg/kg body weight of crude venom. Crude venom was seen to suppress tumor growth by significantly decreasing EAC cell count and cell viability (p&lt;0.01). There was also a significant increase in survival time of the venom-treated tumor-bearing mice (52.3%, p&lt;0.05) in comparison to the non-treated tumor-bearing counterparts. The study of venom effect and/or tumor inoculation on some important...
