| Pharmacological substances such as adenosine deaminase (ADA), collagen, histamine, IgE, myoglobin, and nerve growth factor (NGF) are endogenously present in animals. Research from this laboratory reported decreased levels of ADA, histamine, IgE, and NGF in organs of mice injected with sub-lethal doses of cobra venom. The goal of this research is to observe the levels of ADA, collagen, histamine, IgE, myoglobin, and NGF in certain organs of mice injected with venom from the bee Apis mellifera. Adult Balb/c female mice IM injected with half lethal dose of bee venom were sacrificed after 2 and 8 hours for removal of organs. The homogenates of the organs were assayed by ELISA for ADA, collagen, histamine, IgE, myoglobin, and NGF using respective antisera.... |

| 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... |

| This report documents a case of a melanic specimen of Crotalus durissus terrificus (Laurenti, 1768) found in Bofete, São Paulo State, Brazil. The authors describe this melanic snake, determine the electrophoretic pattern of its venom, and compare the venom of this specimen against that of normal Crotalus durissus terrificus. This report is very important because melanism is a rare chromatic anomaly |

| This study used 15 beehives: five with Africanized queens sisters (Apis mellifera), five with Italian queens sisters (Apis mellifera ligustica), and five with Carniolan queens sisters (Apis mellifera carnica). The queens were fertilized naturally. This experiment was performed in the apiary of the Botucatu School of Veterinary Medicine and Animal Husbandry, UNESP, State of São Paulo, Brazil. The following data were obtained from the foraging bees: venom quantity in reservoir, 0.117±0.015, 0.139±0.020, and 0.147±0.024 (mg); venom quantity liberated in extraction apparatus, 0.073±0.012, 0.057±0.011 and 0.059±0.013 (mg); and sting electro stimulus threshold (volts), 10.75±1.37, 15.11±2.00, and 15.01±1.63 for Africanized, Italian x Africanized and Carniolan x... |

| Eighty-four patients bitten by venomous snakes were studied retrospectively at the School of Medicine of Marilia from January 1990 to August 1994. The majority of these patients were rural workers, 65 (77.38%) males and 19 (22.62%) females, aged eight to seventy-five. Forty-three (51.19%) patients were diagnosed as having been bitten by snakes of the genus Bothrops and 41 (48.81%) by Crotalus. Fifty-eight patients (69.04%) were bitten in the legs and 26 (30.96%) in the arms. January, March, April and November were the months of higher incidence of bothropic envenomations, while crotalic envenomations were not recorded only in August and September. This study showed that the prevalence of crotalic envenomations in Marilia was higher than that of any other... |

| 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... |

| 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... |
