Abstract:Objective To observe the effect of Tiaojing Zanyu Pills on isolated uterine smooth muscle in rats. Methods A certain dose of Estradiol Benzoate was administered intraperitoneally to induce allergy in rats. After 24 h, the rats were killed and the smooth muscle of the uterus was removed, and then oxytocin was added to induce constriction in the smooth muscle of the uterus. Finally, suspension with three different concentrations (0.1854, 0.3705, 0.7394 mg/mL) of Tiaojing Zanyu Pills were added respectively. Results Tiaojing Zanyu Pills had no obvious effects on normal rats in terms of the average tension, frequency and activity of uterine smooth muscle contraction (P > 0.05). However, the medium concentration (0.3705 mg/mL) and high concentration (0.7394 mg/mL) of Tiaojing Zanyu Pills could obviously inhibit the oxytocin which thereby induced contraction of uterine smooth muscle in rats, thus resulting in decrease in the average tension and activity (P < 0.05), but no obvious effect on the contraction frequency was observed (P > 0.05). Conclusion Tiaojing Zanyu Pills can directly inhibit the pathological conditions of the uterine smooth muscle contraction, which may be one of the mechanism of clinical treatment of dysmenorrhea.
