Intraprostatic Injections of various antitumour compounds into rats: Part II. Chronic effects.

Histopathological studies were carried out at intervals of one, two and three months after a single injection of one of seven antitumour compounds into the prostates of adult male CR rats. The histological findings indicate mainly a long term effect of the compounds tested on the glandular epithelium of the rat prostate. The effect is strictly local and no side effects were seen.
