Abstract

The pharmacological effects of hydrocooked extracts of crucian carp have been investigated. All of the hydrocooked extracts showed the contractile effect on the isolated rat duodenum and decreased to a certain extent the normal blood pressure in anesthetized rat. The hydrocooked extracts also exhibited a dose-dependent relaxation on the isolated rat aorta precontracted with 50 mM KCl. All of these except for RM 60 fraction haying cytotoxic effect against MCF-7 human breast cancer cell showed neither antibacterial activity nor antitumor activity. In addition, we found that although body weight gain in the hydrocooked extracts treated group were all reduced significantly compared to control group, there were no significant changes in the hematological parameters, except that the levels of high-density lipoprotein was significantly increased. These results suggest that the hydrocooked extracts of crucian carp may contain a variety of bioactive materials.
