Manganese induced hepatic lesions in carbon tetrachloride pretreated rats.

Manganese sulphate (6 mg/kg) was administered intraperitoneally daily for 30 days in carbon tetrachloride pretreated rats. Histological and histochemical studies in liver tissue revealed extensive damage to hepatic parenchyma in these rats as compared to lesions produced by manganese sulphate alone. These findings suggest that workers, with liver dysfunction ergated in manganese industry may be more susceptible to the toxic effects of this metal.
