Biosynthesis of prostaglandin from labeled polyunsaturated fatty acids as mediators of inflammation and cellular proliferation. 2 - Bioactive compounds from natural source like venoms of snakes and scorpion , algae and its application in biology. 3 - Drugs (c isplatin & cyclosporine) and pollutants (Nitrite, morpholine, Potassium Bromate , lithium , lead, acrylamide & mycotoxins) which induced adverse a ffect s that mediated by oxidative stress in multiple organs. 4 - Xenobiotics (estrradiol & endotoxins) biotrans formation . 5 - Applications of using antioxidants in ameliorating the oxidative stress that induced by some diseases like diabetes and hyperlipidemia that induced by high fat/high sucrose diet . 6 - P revention of diabet es complication by using antioxidants .
