Two groups of 12 woman Horton Sprague-Dawley rats [age unspecified] had been fed a diet supplemented with 300 mg/kg two-acetylaminofluorene (AAF) for forty weeks and/or five% sodium saccharin. Eleven of your controls given AAF and 6/twelve rats fed AAF moreover saccharin designed palpable mammary and ear-duct tumours. Liver tumours were being observed in both equally groups, However they were smaller sized and fewer malignant within the saccharin-fed animals. Microscopic evaluation of your urinary bladders indicated which the mucosal lining was hyperplastic in all rats fed AAF but a lot more notably so in These fed AAF furthermore saccharin; one particular animal fed AAF in addition saccharin had squamous metaplasia and precancerous variations on the mucosal epithelium.
