The influence of surgical transection and anastomosis on the rate of cell proliferation in the colonic epithelium of normal and DMH treated rats

David H. Barkla and Peter M. Tutton

Department of Anatomy, Monash University Clayton 3168, Australia

Normal and DMH-treated male rats aged 18–20 weeks underwent surgical transection and anastomosis of the transverse colon. Animals were subsequently killed at intervals of 14, 30 and 72 days. Three hours prior to sacrifice animals were injected with vinblastine sulphate and mitotic indices were subsequently estimated in histological sections. Possible differences between experimental and control groups were tested using a Student's t-test. The results show that the accumulated mitotic indices in normal and DMH-treated colon are statistically similar. The results also show that transection and anastomosis stimulates cell division in both normal and DMH-treated colon and that the increase is of greater amplitude and more prolonged duration in the DMH-treated rats. Carcinomas developed close to the line of anastomosis in DMH-treated but not in control rats. The results support the hypothesis that non-specific injury to hyperplastic colonic epithelium promotes carcinogenesis.
