To investigate the effect of Curcuma zedoaria on the myoelectric activity of uterus in virgin rats and study its mech anisms.


A pair of bipolar Ag-AgCl electrodes were implanted on the serosal surface of uterus in rats to observe the effect of C. zedoaria on the myoelectric activity of uterus before and after the five agonists were injected intraperitoneally.


Decoction of C. zedoaria significantly increases the spike area, the duration and the number of bursts of action potentials of the uterine smooth muscle and its effect is related dosage. Atropine and phentolamine decreased the exciting effect of C. zedoaria, whereas verapamil, diphenhydramine and indomethacin have no effect on the excitation of C. zedoaria.


C. zedoaria has obvious exciting effect on the smooth muscle of uterus in rats, and its mechanisms may be associated with M-receptor and alpha-receptor.
