Effects on 4080 rats of chronic ingestion of N-nitrosodiethylamine or N-nitrosodimethylamine: a detailed dose-response study.
Four thousand eighty inbred rats were maintained from weaning on various different concentrations of N-nitrosodiethylamine (NDEA) or N-nitrosodimethylamine (NDMA). The principal aim was to characterize the dose-response relationship for the effects of these agents on esophageal cancer (NDEA) or on various types of liver cancer (NDEA and NDMA), although NDEA also caused a few tumors of the nasop...
متن کاملCC]-N-nitrosodiethylamine in mice
Naturally occurring plant products belonging to different chemical classes namely alizari n, an anthraquinone, caffeine, a methyl xanthine derivative and quercetin, a flavonol were studied for their effect on elimination of metabolites of [14C]_N_ nitrosodiethylamine e4C-NDEA) through respiration in mice. Treatment with caffeine, quercetin and alizarin at doses of 200, 9 and 9 JLg/ml respective...
متن کاملDose and time relationships for tumor induction in the liver and esophagus of 4080 inbred rats by chronic ingestion of N-nitrosodiethylamine or N-nitrosodimethylamine.
A Weibull analysis is presented of the dose and time relationships for the effects on 4080 inbred rats of chronic ingestion in the drinking water of 16 different doses of N-nitrosodimethylamine (NDMA) or N-nitrosodiethylamine (NDEA). The sites chiefly affected were the liver (by both agents) and the esophagus (by NDEA only). Since the experiment continued on into extreme old age, effects became...
متن کاملN-Nitrosodimethylamine Carcinogenesis in Nicotinamide-deficient Rats1
Special diets that were extremely low in protein (5.5%) and high in carbohydrate were used to test the effect of nicotinamide on A/-nitrosodimethylamine-induced Carcinogenesis in Holtzman albino rats. The level of nicotinamide in the three diets ranged from 0 mg/kg of food to 50 mg/kg to 500 mg/kg. During the treatment with these diets (5 weeks) and the carcinogen (18 days), the renal and hepat...
