| Abstract: | Rat serum and liver ICDH, OCT, GOT and GPT activities are significantly elevated 2-6 hr after i.p. injections of single doses (2.5 mg/kg body wt) of dichlorvos. ICDH, OCT, GOT and GPT activities are significantly increased in serum and liver of rats receiving daily injections (0.25 mg/kg body wt) for 7 days. Although liver SD is significantly elevated in the single and repeated dosage study, serum SD appears unaffected at these levels of dichlorvos toxicity. Changes in serum OCT activity estimations maybe a useful single parameter for screening pesticides for potential hepatotoxic effects in humans and farm animals. |
