title: Effect of calorie restriction on the fate of hyperplastic liver nodules induced by concurrent administration of lasiocarpine and thioacetamide.
abstract: 1 Hyperplastic liver nodules were induced in F-344 rats by concurrent administration of lasiocarpine (50 ppm in diet) and thioacetamide (50 mg/kg body weight twice weekly) for 15 weeks. 2 The effect of carbohydrate calorie and total calorie restriction on the fate of hyperplastic liver nodules was examined. 3 The incidence of hepatocellular carcinoma was the same in all groups of rats irrespective of the magnitude of carbohydrate calorie restriction and 50% total calorie restriction. 4 These studies demonstrate that carbohydrate or total calorie restriction has no effect on the progression of hyperplastic nodules to hepatocellular carcinoma.
