Abstract:
Object To observe the effects of coumarin (CM) and Verapamil (Ver) on contractivity and its relationship with Ca 2+ in isolated ileal smooth muscle of the rabbits. Methods The effects of CM and Ver were observed in three doses by routine experimental methods in isolated rabbit ileal. Results CM and Ver inhibited the contraction of isolated ileal smooth muscle induced by acetylcholine and CaCl 2. The responses were a concentration-dependent and non-competitive manner. CM and Ver were effective against the initial and sustained peak induced by acetylcholine. Conclusion CM has a calcium-antagonistic effect which is similar to that of Ver.
