Abstract

Equigan is an androgenic steroid that improves the growth and food conversion in meat producing animals. The present study was performed to determine the ameliorating effect of propolis in the toxicity of the rat testes induced with Equigan. Fourty male albino rat were divided into four groups (10 animals each); the control group includes animals that injected intramuscularly with olive oil. The second group includes rats received propolis. The third group is the experimental group included animals that received intramuscular injections of Equigan. The last group was co-administrated group where rats received Equigan along with propolis. The results suggest that misuse of growth promoter Equigan may contribute to continuous damage of the testicular function and structure that shown a significant increase in nitric oxide (NO), malondialdehyde (MDA), testosterone, follicle stimulating hormone (FSH) and luteinizing hormone (LH) in Equigan group when compared to the control group, these results decrease in co-administrated Equigan with propolis. On the other hand a significant decrease in superoxide dismutase (SOD), catalase, Glutathione (GSH) and total thiol in Equigan group when compared with control group, and a significant increase in co-administrated Equigan with propolis. It was concluded that; propolis has ameliorating role on the biochemical alterations in Equigan induced testicular toxicity in male rat.

Vol.2 No.1 -7 : Potential hepatoprotection exerted by ginseng against chlorpyrifos-induced hepatotoxicity in albino rats.

Abstract

Insecticides gained public reputation and widespread application to control the spread of different insects in various habitats. However, the deleterious effects of these chemicals could not be ignored and should be dealt seriously. The present work was conducted to test the efficacy of the natural plant ginseng in alleviating toxicity of chlorpyrifos. The organophosphorus insecticide chlorpyrifos induced hepatotoxicity and changes in some serum biochemical parameters. The liver of rats administered chlorpyrifos manifested cytoplasmic vacuolization, leucocytic infiltration, hemorrhage and remarkable dilatation of veins. The nuclear chromatin was condensed. There was a significant increase in alanin aminotransferase (ALT) while there was a significant decrease in albumin, catalase (CAT) and superoxide dismutase (SOD) in the serum of treated rats. Treating animals with ginseng was found in this study to alleviate hepatotoxicity and restore the levels of the tested serum parameters to nearly normal values.
