摘要
目的:研究鸡鸣散(Ji-Ming-San,JMS)对动物模型的镇静、利尿、抗凝作用;探讨鸡鸣散药理作用的昼夜节律性差异,验证前人关于鸡鸣散择时用药的科学性。方法:以小鼠走动时间、前肢上举次数和自主活动为指标观察鸡鸣散镇静作用及其昼夜差异;用代谢笼法观察鸡鸣散利尿作用及其昼夜差异;用玻片法观察鸡鸣散抗凝作用及其昼夜差异。结果:鸡鸣散对小鼠有明显的镇静作用,使小鼠走动时间、举上肢次数及活动次数均明显减少,用药后小鼠原有活动昼夜节律消失;鸡鸣散有良好的利尿作用,用药后明显增加排尿量,且作用呈昼夜差异,夜间用药效果明显优于白昼;鸡鸣散有明显的抗凝作用,用药后明显延长小鼠凝血时间(CT),且作用呈昼夜差异,白昼用药CT延长显著长于夜间。结论:鸡鸣散具有良好的镇静、利尿及抗凝作用,且利尿、抗凝作用呈昼夜节律性差异,在动物休息期末、活动期初用药疗效较好。
AIM： To study the sedation, diuresis and anticoagulation effects of Ji-Ming-San （JMS） in animal models for exploring the circadian variations of the dosing action and verifying the rationality of administering JMS on special time. METHODS： The sedation effect and circadian difference were determined by observing the time session of ambulation, raising double-forefoot test and autonomic activity of model mice. The diuretic effect and the circadian variation in rats were examined by metabolic cage test while the anticoagulation and the circadian change were observed by glass test. RESULTS： JMS produced significant sedation effect by reducing time session of ambulation, raising upper limbs frequencies/time and autonomic activity and the built-in rhythm with autonomic activity disappeared after JMS administration. JMS had satisfactory diuretic effect and total urinary output in water-loaded rats was increased after dosing. The diuretic effect of dosing showed a circadian rhythm with more significant output during the night than that during the daytime. Also, JMS prolonged the clotting time significantly and the action exhibited circadian difference. As compared with administration at the night, the clotting time was more prolonged at the daytime. CONCLUSION： JMS can produce obvious sedation, diuresis and anticoagulation effects with varied circadian rhythm. The findings suggest that the effect of administering JMS is better at the end of rest phase than other time session.
