尿感宁的主要药效学研究

Studies on the Pharmacodynamics of Niao Gan Ning

目的研究尿感宁的抗炎、抑菌、利尿、解痉和增强机体免疫力的作用。方法分别采用小鼠腹腔白细胞游走抑制试验、药物体外抑菌试验、水负荷代谢笼试验、离体平滑肌张力记录法及小鼠腹腔巨噬细胞功能试验,研究尿感宁的药效作用。结果尿感宁能抑制小鼠腹腔白细胞游走,使白细胞数明显减少;对各菌种表现出不同程度的抑制作用,使水负荷大鼠每小时尿量增加;抑制由氨乙酰胆碱(Carbacol)和组胺引起的兔及大鼠膀胱平滑肌、输尿管平滑肌的收缩;此外尿感宁还可明显增强小鼠腹腔巨噬细胞吞噬鸡红细胞的能力。结论尿感宁具有较强的抗炎、抑菌、利尿、解痉作用。

Objective: To investigate the anti-inflammatory, bacteriostatic, diuretic, antispasmodic and immunoenhancement effect of Niao Gan Ning(NGN). Methods: The tests of inhibiting the leukocyte infiltration, in-vitro bacteriostasis, water loading with metabolism cage, isometric tension recording and the phagocytosis of abdominal macrophages(AM) were conducted. Results: NGN could obviously inhibit the wandering of leukocyte in abdominal cavity and decreased the number of WBC in mice, and exert bacteriostatic effect to various degrees. NGN also increase the urine volume in water load rats, inhibited contraction of bladder and ureter smooth muscle induced by Carbacol and histamine in rabbits and rats, and increased phagocytosis of the chicken red cells by AM. Conclusion: NGN has a strong anti-inflammatory, bacteriostatic, diuretic and antispasmodic effect.
