EFFECT ON CURCUMIN ON CHOLESTEROL GALLSTONE INDUCTION IN MICE

A study was. carried out on the efficacy of curcumin in reducing the incidence of cholesterol gall-stones (CGS), induced by feeding a lithogenic diet in young male mice. Feeding a lithogenic diet supplemented with 0.5 per cent curcumin for 10 wk reduced the incidence of gall-stone formation to 26 per cent, as compared to 100 per cent incidence in the group fed with lithogenic diet alone. Biliary cholesterol concentration was also significantly reduced by curcumin feeding. The lithogenic index which was 1.09 in the cholesterol fed group was reduced to 0.43 in the 0.5 per cent curcumin supplemented group. Further, the cholesterol : phospholipid (C/PL) ratio of bile was also reduced significantly when 0.5 per cent curcumin supplemented diet was fed. A dose-response study with 0.2, 0.5 and 1.0 per cent curcumin supplemented lithogenic diets showed that 0.5 per cent curcumin was more effective than a diet with 0.2 or 1 per cent curcumin.
