Résumé
To determine the effects of lead where lead accumulates maximum (liver followed by kidney), liver and kidney functions were studied using low oral dose of lead nitrate for prolonged duration. Dose of 20 mg lead nitrate/kg body wt/day was used in male albino rats. AST and ALT levels altered independently. When ALT remained unaltered after 7 and 21 days of treatment, it is decreased by 13.21% after 14 days treatment. AST was marginally lowered after 7 days, increased after 14 days and increased marginally after 21 days. Bilirubin (conjugated, unconjugated and total) decreased after 7 and 14 days and increased after 21 days. Urea increase was directly proportional to duration. Creatinine remained unaltered.

'Mandur bhasma', an ayurvedic preparation of iron is used in traditional medicine against hepatitis. In the present study the hepatoprotective property of this drug was tested in albino rats during CC14 induced hepatic injury. The effect of mandur bhasma on the activities of the lipolytic enzymes of rat liver, kidney and adipose tissue were studied during hepatitis induced by CCl4. The activities of acid lipase, alkaline lipase, lipoprotein lipase and hormone sensitive lipase exhibited significant alterations during CCl4 induced hepatic injury, indicating a role for these enzymes in the mobilization of fat from adipose tissue and accumulation of fat in liver and kidney. Simultaneous treatment with mandur bhasma prevented the paraffin mediated and CC14 mediated changes in the enzyme activities. These results suggest the hepatoprotective role of mandur bhasma during CC14 induced hepatic injury.
