Abstract
-
Hyperplasia of the uninary bladder epithelium in Wistar strain female rats after administration of 0.05% N-butyl-N-(4-hydroxybutyl) nitrosamine(BBN) was examined histologically and the effect of fat diet on the development of hyperplasia of the urinary bladder was studied. Hyperplasia of the urinary bladder epithelium was consistently observed after 4 weeks, and its extent increased with the period of BBN administration. Some of the hyperplastic lesion, showed a tendency to regress following removal of the carcinogenic stimuli. High fat diet has no effect on hyperplastic change of the urinary bladder in rats.
