ABSTRACT
OBJECTIVE:To explore the spasmolytic effect of baked Radix Vladimiriae on in vitro intestinal muscle in rabbits. METHODS:Magnus in vitro intestinal muscle accumulative dose method was adopted to observe the dose-effect relationship of petroleum ether parts of baked Radix Vladimiriae with in vitro intestinal muscle of rabbits and its impact on the spasm of rabbit intestinal muscle induced by acetylcholine, histamine phosphate and Bacl2. RESULTS:There was a certain dose-effect relationship between petroleum ether parts of baked Radix Vladimiriae and spasmolytic mechanism of rabbit in vitro intestine. It showed the effect of acetylcholine, histamine phosphate and Bacl2. CONCLUSION:The inhibition effect of petroleum ether parts of baked Radix Vladimiriae on normal in vitro intestinal muscle increase as long as dose increase. The inhibition mechanism may be associated with acetylcholine competing with histamine to block M receptor and H1 receptor as well as to inhibit excitability of intestinal muscle.
