In male Fischer 344 rats, the diploma of hyperplasia and microvillus development induced by freeze-ulceration inside the bladder epithelium was equivalent during the next two-7 days interval whether 5% sodium saccharin was administered right away following the treatment. The team obtaining sodium saccharin only didn't present hyperplastic adjustments in this time interval.
