Effect of propolis extract on guines pig lung mast cell J. Venom. Anim. Toxins incl. Trop. Dis.
Orsi,R. O.; Sforcin,J. M.; Funari,S. R. C.; Gomes,J. C..
The direct effect of ethanolic extract of propolis on guinea pig lung cell suspension containing mast cells, as well as its influence on the histamine release induced by antigen (ovoalbumin 10 mug/ml) and ionophore A 23187 (3 muM) were investigated. Propolis ethanolic extract (300 mug/ml) increased the histamine release in guinea pig lung suspension containing mast cells by a cytotoxic effect. Lower concentrations of propolis had no effect on histamine release. Our results demonstrated that propolis (3, 10, 30, and 100 mug/ml) shows no significant effect on the histamine release induced by ionophore and antigen. Based on these results, we suggest that propolis could directly activate mast cells, promoting inflammatory mediators release by cytotoxic...

Antioxidant activity of bee products added to water in tebuconazole-exposed fish Neotropical Ichthyology
Ferreira,Daiane; Unfer,Taís Cristina; Rocha,Hélio Carlos; Kreutz,Luiz Carlos; Koakoski,Gessi; Barcellos,Leonardo José Gil.
An experiment was conducted to evaluate the potential of honey, propolis, and bee pollen for the reversal of lipid peroxidation induced by tebuconazole (TEB) in South American catfish (Rhamdia quelen), in which the concentration of thiobarbituric acid reactive substances (TBARS), the activity of the antioxidant enzyme glutathione-S-transferase (GST) and the concentrations of non-enzymatic antioxidants, reduced glutathione (GSH), ascorbic acid, and non-protein thiols were assessed. Honey (0.125 g L-1) and bee pollen (0.05 g L-1) added to the water reverse the production of TBARS induced by TEB, while propolis demonstrated a pro-oxidant effect, inducing an increase in TBARS production. The data presented herein suggest that the addition of water to honey and...

Similitude Pattern and Botanical Origin of the Chilean Propolis: [with 2 figures & 4 tables] Phyton
Montenegro,G; Mujica,AM; Peña,RC; Gómez,M; Serey,I; Timmermann,BN.
Correspondence analysis allows identifying various kinds of propolis due to botanical source. The first site, Colliguay is identified by a higher content of pollen of Escallonia pulverulenta, and Nothofagus dombeyi. Two other very close sites are La Vacada and Quilaco, where pollen of Mentha pulegium, besides Echium, Cichorium, and Luma are frequently identified. Other groups including various contents of pollen of Eucalyptus, Salix or Prunus and other native resources such as Peumus, Cryptocarya and Quillaja are not well defined.

Preliminary studies of alternative feed additives for broilers: Alternanthera brasiliana extract, propolis extract and linseed oil Rev. Bras. Ciênc. Avic.
Biavatti,MW; Bellaver,MH; Volpato,L; Costa,C; Bellaver,C.
The influence of alternative treatments using fluidextracts of Alternanthera brasiliana, propolis resin and linseed oil on the performance and blood biochemistry of broilers was evaluated. The study was done with five treatments: basal diet (negative control); basal diet + 40 ppm avylamicin and 120 ppm monensin (positive control); basal diet + A. brasiliana extract (180 mL/200 kg of feed); basal diet + propolis extract (200 mL/200 kg of feed) and basal diet + linseed oil (2.5% replacing soybean oil). Propolis and A. brasiliana extracts improved broiler performance from 14 to 21 days, whereas linseed oil had no effect. The findings of this experiment revealed that A. brasiliana and propolis extracts can be used as antimicrobials, but further studies are...

The effects of a combination of garlic, oyster mushroom and propolis extract in comparison to antibiotic on growth performance, some blood parameters and nutrients digestibility of male broilers Rev. Bras. Ciênc. Avic.
Daneshmand,A; Sadeghi,GH; Karimi,A.
A study was conducted to evaluate the combined effects of garlic, oyster mushroom and propolis extract on the growth performance, organ weights, antibody response to Newcastle Disease Virus (NDV), serum lipid concentrations and nutrient digestibility of male broilers. A total of 192 day old chicks (Ross 308) were randomly assigned to 3 treatments with 4 replications (16 birds per replication). Experimental treatments were a maize- soybean based diet as control, control diet supplemented with a combination of garlic (30 g/kg), oyster mushroom (2 g/kg) and propolis extract (0.2 g/kg) known as GMP, and control diet supplemented with Virginamycin (0.25 g/kg) as antibiotic. The inclusion of GMP decreased (p < 0.05) live body weight, average daily gain and...

The Effects of In-Ovo Injection of Propolis on Egg Hatchability and Starter Live Performance of Japanese Quails Rev. Bras. Ciênc. Avic.
Aygun,A.
ABSTRACT The purpose of this study was to determine the effects of in-ovo injection of a propolis water extract on hatchability, embryonic mortality, starter live performance, and livability of Japanese quails. In total, 500 fresh hatching eggs were randomly distributed into five treatment groups of 100 eggs per treatment with four replicates of 25 eggs each. On day 14 of incubation, eggs from group 1 were not injected (control), group 2 was injected with distilled water (water), group 3 was injected with 1% propolis water extract (1% propolis), group 4 was injected with 2% propolis water extract (2% propolis), and group 5 was injected with 3% propolis water extract (3% propolis). A completely randomized design was applied, and data were analyzed using the...

In vitro fermentation characteristics of ruminant diets using ethanol extract of brown propolis as a nutritional additive R. Bras. Zootec.
Gomes,Maria de Fátima Falcão; Ítavo,Camila Celeste Brandão Ferreira; Ítavo,Luís Carlos Vinhas; Leal,Cássia Rejane Brito; Silva,Jonilson Araújo da; Heimbach,Natália da Silva; Leal,Eduardo Souza.
ABSTRACT The addition of levels of ethanol extract of brown propolis was evaluated by assessing diet degradation in rumen fluid and predicting cumulative in vitro gas production by nonlinear (dual pool logistic and exponential) models. A total of 35 g of crude propolis were extracted in 65 mL of cereal alcohol (95% ethanol). In a completely randomized factorial design, the experimental diets combined four concentrations of extracted propolis diluted in cereal alcohol (0, 50, 70, and 100% of propolis extract) and supplementation doses (4, 8, 12, 16, and 20 mL/kg dry matter), tested in triplicate. Diet (400 g/kg Tifton hay and 600 g/kg concentrate) was incubated for 96 h carried out three times in three different weeks. There was significant interaction...

Candida sp in the oral cavity with and without lesions: maximal inhibitory dilution of Propolis and Periogard Rev. Microbiol.
Azevedo,Rosa Vitória Palamin; Komesu,Marilena Chinalli; Candido,Regina Celia; Salvetti,Cristiane; Rezende,Fausto Hanaoka Caetano.
Fifty individuals of both sexes aged on average 45.2 years were evaluated at the Semiology Clinic of FORP-USP in order to isolate and identify yeasts from the oral cavity, with and without lesions, and to determine the maximal inhibitory dilution (MID) of the commercial products Propolis (Apis-Flora) and Periogard (Colgate) against the strains isolated. Yeasts of the genus Candida were detected in the saliva of 9/19 (47.4%) individuals with a clinically healthy mouth, 18/22 (81.8%) of individuals with oral lesions, and in 4/9 (44.4%) of patients with deviation from normality, and were detected in 19/22 (86.4%) of the lesions. In the group with oral candidiasis, we isolated in tongue and lesion, respectively for each specie: C.tropicalis (8% and 10.7%),...
