dc.description We have examined the effect of subchronic methidathion ( MD) administration on heart damage, and have evaluated possible ameliorating effects of a combination of vitamins E and C against MD toxicity. The experimental groups were: control group, rats treated with 5 mg/kg MD and rats treated with 5 mg/kg body weight MD plus vitamin E and vitamin C ( MD + Vit). The groups were given MD by gavage 5 days a week for four weeks at a dose level of 5 mg/kg/day ( MD and MD + Vit) by using corn oil as the vehicle. Vitamin E and vitamin C were injected at doses of 50 mg/kg i.m. and 20 mg/kg i.p., respectively, after the treatment with MD in the MD + Vit group. The levels of malondialdehyde (MDA) were determined in the heart tissue, and the levels of cardiac troponin I (TnI) in serum. An autoanalyser was used to determine the serum activities of cholinesterase (ChE). Histopathological examination was carried out in the heart tissue. MDA significantly increased in the MD group as compared to controls (P< 0.01). When MD was given concurrently with vitamins E and C, the increase in MDA was significantly less (P< 0.01). ChE activity significantly decreased in the MD group as compared to controls (P< 0.01). When MD was given concurrently with vitamins E and C, the decrease in ChE activity was significantly higher (P< 0.05). The serum TnI levels significantly increased in the MD group as compared to controls (P< 0.01). When MD was given concurrently with vitamins E and C, the increase in the serum TnI was significantly less (P< 0.01). MD caused the diffuse loss of striation and myocytolysis of the cardiomyocytes, whereas the combination of vitamins E and C caused a significant decrease in these effects of MD. In conclusion, subchronic MD administration caused heart damage and, in addition, treatment with a combination of vitamins E and C after the administration of MD reduced heart damage caused by MD.
