title: Protective effect of butylated hydroxytoluene against induction of gastric cancer by N-methyl-N'-nitro-N-nitrosoguanidine in Wistar rats.
abstract: The effects of butylated hydroxytoluene (BHT) on the incidence and histology of gastric cancers induced by oral administration of N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) were investigated in Wistar rats. Oral administration of 1.0% BHT in regular chow pellets during treatment with MNNG for 25 weeks significantly reduced the incidence of gastric cancers in experimental week 40. BHT had no influence on the histological type of adenocarcinomas induced in MNNG-treated rats. BHT alone induced slight glandular hyperplasia, but not moderate glandular hyperplasia or gastric cancer.
