Abstract:
Objective To explore the mechanism of Niaochangshu capsule in the treatment of postmenopausal overactive bladder, through observing its influence on bladder weight and the expression of eNOS and AQP1 of ovariectomized female rats. Methods Female SD rats were divided into blank group, model group, Nilestriol group and Niaochangshu group. Rats were removed ovaries except the blank group. The treatment groups were given corresponding drugs, blank group and model group were given normal saline by gavage. After 4 weeks, the bladders' weight and thickness were detected, the expressions of eNOS and AQP1 in serum and bladder tissue were determined by ELISA, and NO by spectrophotometry. Results Ovariectomy resulted in decreased bladder weight, bladder mucosal and muscular atrophy, and opposite changes showed after given Niaochangshu. The expressions of eNOS and NO in bladder and serum were decreased significantly after ovariectomy, while increased by given Niaochangshu capsule or nylestriol (P<0.05), and there was significant difference between Niaochangshu group and Nilestriol group (P<0.05). The expression of AQP1 was decreased in the model group, and increased after given nylestriol or Niaochangshu capsule. While the expression of AQP1 in bladder had no significant difference among the four groups. Conclusion Niaochangshu capsule can reverse bladder mucosal and muscular atrophy caused by estrogen deficiency, and increase the content of eNOS in serum and bladder, thus play the role in the treatment of postmenopausal overactive bladder.
