威灵仙的解痉抗炎镇痛作用

目的：研究威灵仙的解痉抗炎镇痛作用。方法：1）豚鼠离体回肠标本，观察威灵仙对其的舒张作用。并观察威灵仙对抗组胺和乙酰胆碱引起的回肠收缩作用。2）利用扭体法，观察威灵仙的镇痛作用。3）制备二甲苯致炎和纸片肉芽肿炎症模型。观察威灵仙的抗炎作用。结果：威灵仙注射液能松弛豚鼠回肠，并能对抗组胺和乙酰胆碱引起的回肠收缩反应；威灵仙注射液还能明显减少冰醋酸所致的小鼠扭体次数，延长潜伏期。威灵仙能极显著抑制二甲苯引起的小鼠耳朵肿胀，其作用有较好的线性关系；同时，威灵仙还能显著抑制纸片引起的大鼠肉芽组织生长。证明威灵仙有抗炎镇痛和松弛平滑肌作用。

Antispasmodic Anti-inflammation and Analgesic Effect of Clematis

Objective: To evaluate the pharmacodynamic of clematis. Methods: 1) The relaxation of isolated ileum muscle of guinea pig by clematic was tested. The antagonism of clematis on histamine or Ach induced ileum muscle contraction was tested also. 2) By using the model of turning of trunk, the pain releasing effect of clematis was evaluated. 3) The experiments about anti-inflammation action of clematis were carried out in two models. Results: Clematis relaxed the ileum muscle. It also antagonized the contraction of the muscle caused by histamine and Ach. A single intrapeditional administration of clematis to Kun-Ming mice significantly prolonged the latency and reduced the writhe number at the turning of trunk model; clematis dose-dependently inhibited the mouse ear swelling caused by xylol. It also had anti-inflammation effect at the other model. The results demonstrated that clematis could release the pain, suppress the inflammation and smooth muscle contraction.
