The functional and morphological study about the action mechanism of the sacral acupuncture stimulus to overactive bladder model rats.

通过功能形态学研究，探讨针刺对膀胱过度活动模型大鼠欲空传递系统的作用机制。乙酸致膀胱刺激大鼠和氯致膀胱炎大鼠经骶针刺激后，间缩间期增加。观察骶部针刺对膀胱粘膜恢复过程的影响。骶针刺激可通过不同于药物的作用机制有效改善尿频，并可预期对耐受性过动膀胱的作用。

This study of functional morphology was performed to investigate the action mechanism of the acupuncture for the transfer system of desire-to-void using overactive bladder model rats. The intercontraction interval was increased immediately after sacral acupuncture stimulation in acetic acid-induced bladder irritation rats and chloride-induced cystitis rats. And we observed the change of the recovery course of bladder mucosa by performing a sacral acupuncture. Sacral acupuncture stimulus is effective in improving urinary frequency by different action mechanism from medication, and can expect the effect on the overactive bladder of tolerance.
