Abstract
Pesticide residues of (malathion, plrimiphos methyl. chlorpy 'los methyl,
carbosulfan and methomyl ) were extracted from watermelon (seeds, pe I and plup}. These residues were determined and their effects on \he enzyme activilles of albino rats were measured. Results revealed that Plasma ChE activity was significantly decreased in all treated rats groups with all pesticides tested and their re idues in a/l experimental period. Carbosulfan and chlorpyrifos methyl exhibited the m st effective compounds in the ChE activity. The inhibition percent were 23.5 % a d 17.33 % respectively .Plasma AST activity was decreased after 48 hours of treatment with the organophosphorus pesticides tested while with the carbamate cornpcuncs it was increased. On the other hand, these activilles were Increased after 21 days of treatment wIth malathion and a/l carbamate compounds lested compared l.vith that of control.Plasma AL T activity was decreased after 48 hours from trea ment with malathion, and chlorpyrifos methyl. Contrar»y, AL T activity was increased after 21 days or treatment wilh malathion. pirimiphos methyl, carbosulfan and methomyl compared with that of control. Plasma alkaline phosphatase activity was s gnificantly increased with all tested pesticides and their residues in all experime tal period compared with that of control. The maximum percent of increasing was found with the carbamate pesticide, carbosulfan, Total protein concentration in plasma was decreased with all tested pesticides and their residues after 48 hours from t eatments and the maximum percent of decreasing was found with malathion (70.49 Co) . Also, lotal protein concentration was increased with all tested pesticides and thei residues after 21 days from treatments compared with that of control. Albumin conce Iration in plasma was increased in all experimental period with malathion, pirlmiphos methyl. carbosulfan and methomyl compared with thaI of control. In contrary albumin concentration was decreased with chlorpyrifos methyl pesticide in all experimental period. Plasma cholesterol concentration was also decreased with malathion. pirimiphos methyl. cartosulfan and methomyt. The maximum percent of decreasing was occured with carbosulfan (56.57 %). Only chlorpyrifos methyl Insectlcid showed an increasing the cholesterol concentration compared with that of control.
