Protective effects of a wheat germ rich diet against the toxic influence of profenofos on rat tissue lipids and oxidative pentose phosphate shunt enzymes
Keywords:Lipids profile, Profenofos, Rats, Wheat germ
The effects of technical and formulated forms of profenofos on the metabolic lipid fractions of the liver, brain and kidneys as well as the activity of glucose-6-phosphate dehydrogenase (G6PD) and 6-phosphogluconate dehydrogenase (6PGD), which consider lipid related enzymes, were studied. The two forms of profenofos were given separately either orally or by dermal at doses of 1/20 LD50 for 3 months (one dose every 48 h). Total lipids and lipid fractions (cholesterol, triglycerides and phospholipid contents) decreased in the three studied organ tissues either in technical or formulated profenofos-induced rats compared with normal control animals. The highest effect was observed in the case of orally formulated profenofo induction, and the lowest was detected for the dermal technical one. The same trend was found in the activities of G6PD and 6PGD associated with lipid metabolism in the liver, brain and kidney tissues under the same conditions. On other hand, the treatment of profenofos-induced animals by feeding a wheat germ rich diet (as antioxidant agent) produced significant improvements in both lipid fraction content and enzyme activity. In addition, the effects of the wheat germ rich diet (α-tocopherol rich source) readjusted and improved the disturbed metabolic fractions of the lipid profiles in the profenofos-induced rats as well as their related enzyme activities (G6PD and 6PGD: oxidative pentose phosphate shunt).
