Activity of erythrocyte antioxidant enzymes of rabbits during chronic acephate treatment

ABSTRACT

The influence of Acephate (an organophosphorous pesticide) on some red cell antioxydant enzymes was studied. Acephate of the doses of 20mg and 40mg/kg of body mass/day was administered on rabbit during 30 days continuously. The activity of superoxyde dismutase (SOD), glutathion peroxydase (GP2), glutathion reductase (TAS) in plasma was determined before and after the intoxication. Results showed a reduce of SOD, GR levels in the day 15 and 31 and a reverse to normal level in the day 45, SOD enzyme and GR enzyme levels reduced in day 15 and 31, while GPx activity increased. Total antioxydation was not varied.
