|Residential and agricultural pesticide use is widespread in the world. Their extensive and indiscriminative use, in addition with their ability to interact with biological systems other than their primary targets constitute a health hazards to both humans and animals. The goal of this work was to study the effects of chronic exposure to diazinon and evaluate the ameliorating effect of mesna as antioxidant. 40 adult male rats were classified-control, diazinon and treated groups. Blood samples were taken and pancreas was removed for histopathological, ultra-structural and biochemical studies. A significant increase in the levels of malondialdehyde, tumor necrosis factor-α, myeloperoxidase activity, interleukin-1β and serum glucose in the toxicated group with diazinon were observed while there was significant reduction in GSH and in serum insulin levels. After treatment with mesna a significant reduction was observed in the previously mentioned parameters and a significant rise in GSH and in insulin levels. Histopathological and ultra-structural studies showed destruction in pancreatic tissues and the β cells were the most affected cells among the injured islets. The current study try to spot light about the effects of chronic exposure to pesticides on vital organs as pancreas also has the role of oxidative stress that may be induced by them in evoking their toxicity. This study shows the role of antioxidant drugs in ameliorating or preventing the toxicity. This appears to be a promising approach that may be considered as a complementary treatment of pesticide toxicity.|
