Residential and agricultural pesticide use is widespread in the world. Their indiscriminative use with their ability to interact
with biological systems, constitute a health hazard. 40 adult male rats were classified into three groups; control received corn
oil (10mg/kg/day). Diazinon received diazinon (10mg/kg/day). Mesna group (15 rats) received mesna 180mg/kg once a week 15
min before administration of diazinons. At the end of the experiment (2 months), animals were anesthetized , blood samples were
taken for glucose and insulin assays & pancreas were removed and divided into 3 portions; for histopathological, ultrastructural
and biochemical studies. A significant increase in the levels of malondialdehyde, TNF-?, myeloperoxidase activity, IL-1? , serum
glucose levels in the toxicated group were observed , while a significant reduction was noticed in GSH and in serum insulin levels.
After treatment with mesna a significant reduction was observed in the previously mentioned parameters except that there was a
significant rise in GSH & in insulin levels. Histopathological and ultrastructural studies showed destruction in pancreatic tissues and
the ? cells were the most affected cells. This study shows the role of antioxidant drugs in ameliorating the toxicity that is considered
as a complementary treatment of pesticide toxicity.
