摘 要 ：目的：研究鳄鱼止咳膏的镇咳、祛痰、抗炎以及免疫调节作用。方法：设立模型对照组、鳄鱼止咳膏(0.43,1.30,3.90,11.7 g·kg^-1)给药剂量组、阳性药组分别为地塞米松组、念慈庵组。采用小鼠氨水引咳和气管酚红排泄法评价鳄鱼止咳膏的镇咳和祛痰作用；采用二甲苯致小鼠耳肿胀法、角叉菜胶致大鼠足肿胀法及大鼠棉球肉芽肿法评价鳄鱼止咳膏的抗炎作用；通过碳廓清和血清溶血素的测定评价鳄鱼止咳膏对免疫低下小鼠的免疫调节作用。结果：鳄鱼止咳膏能够明显延长小鼠的咳嗽潜伏期,减少咳嗽次数,并极显著的抑制小鼠耳廓肿胀度(P<0.001)和大鼠足趾肿胀,对大鼠棉球致肉芽肿增生也起到较强的抑制作用。此外,11.70 g·kg^-1鳄鱼止咳膏也能显著提高免疫低下小鼠的碳廓清指数(P<0.05)以及血清溶血素水平(P<0.01)。结论：鳄鱼止咳膏具有明显的镇咳、祛痰、抗炎以及免疫调节作用。

Abstract:Objective: To research the effects of Alligator Zhikegao on relieving cough, dispelling phlegm and anti-inflammation. Method: The coughing tests in mice, the phenol red secreting tests in mice, ear edema tests in mice,and paw edema tests and subcutaneous cotton ball granuloma in rats were adopted for observing the related pharmacological effects of Alligator Zhikegao. Result: Alligator Zhikegao could obviously prolong the latent period and decrease the times of mouse coughing, and remarkably inhibit the mouse ear edema (P<0.001), the rat paw edema and the hyperplasia of subcutaneous cotton ball granuloma in rats. Alligator Zhikegao 11.70 g·kg-1 could significant improve the carbonic clearances of macrophages (P<0.05) and the hemolysin level in serum (P<0.01). Conclusion: Alligator Zhikegao has significant effects on relieving cough, dispelling phlegm, anti-inflammation and immunological regulation.
