Inhibitory effect of reserpine on N-2-fluorenylacetamide-induced hepatocarcinogenesis in rats. 1987

S Sugie, and T Tanaka, and T Kuniyasu, and H Mori

The effect of reserpine on N-2-fluorenylacetamide (FAA)-induced hepatocarcinogenesis was examined in female ACI rats. The incidence of hepatocellular altered foci (number/cm2) in rats of group 1 given FAA (0.02% in diet) and reserpine (subcutaneous injections of 1 microgram/g body weight, once a week) simultaneously for 10 weeks, and fed a basal diet for 17 weeks was significantly smaller than that of group 3 exposed to FAA alone for 10 weeks and given the basal diet for the subsequent 17 weeks (1.51 +/- 0.58 vs. 11.46 +/- 3.13, P less than 0.001). Similarly, the incidence of the foci of group 2 given reserpine for 16 weeks after discontinuation of FAA exposure for 10 weeks and a one-week interval of basal diet, was also significantly smaller than that of group 3 (1.51 +/- 0.62 vs. 11.46 +/- 3.13, P less than 0.001). No hepatocellular foci were seen in rats of group 4 given reserpine alone for 27 weeks and group 5 (untreated controls). These results indicate that reserpine has an inhibitory effect on FAA-initiated hepatocarcinogenesis.

D012110	Reserpine	An alkaloid found in the roots of Rauwolfia serpentina and R. vomitoria. Reserpine inhibits the uptake of norepinephrine into storage vesicles resulting in depletion of catecholamines and serotonin from central and peripheral axon terminals. It has been used as an antihypertensive and an antipsychotic as well as a research tool, but its adverse effects limit its clinical use.
