芩连利咽合剂抗炎抑菌药效学

Anti-inflammation and Bacteriostasis Effects of Qinlian Liyan Heji

目的对芩连利咽合剂的抗炎抑菌作用进行药效学研究。方法采用醋酸诱导小鼠毛细血管通透性亢进模型、蛋清诱导大鼠足跖肿胀模型以及棉球诱导小鼠肉芽肿模型研究芩连利咽合剂抗炎作用;采用琼脂稀释法测定芩连利咽合剂对金黄色葡萄球菌、表皮葡萄球菌、卡他莫拉菌、肺炎克雷白杆菌的最小抑菌浓度;采用微量稀释法测定芩连利咽合剂对A群链球菌、肺炎链球菌、流感嗜血杆菌的最小抑菌浓度。结果与阴性对照组比较,芩连利咽合剂中、大剂量组显著抑制醋酸致小鼠腹腔毛细血管通透性亢进;芩连利咽合剂小、中剂量组显著减轻2,3,4,5 h大鼠足跖肿胀度,大剂量组显著减轻1,2,3,4,5 h大鼠足跖肿胀度;芩连利咽合剂各剂量组均显著减轻棉球致小鼠肉芽组织质量。体外抑菌实验发现芩连利咽合剂对7种细菌有不同程度的抑制作用。结论芩连利咽合剂具有显著的抗炎抑菌作用。

Objective To study the mechanism of anti-inflammation and bacteriostasis effect of Qinlian Liyan Heji. Methods To assess the anti-inflammatory effect, blood capillary permeability in mice was increased by acetic acid, the swelling of toe in rats was induced by albumen, and granuloma was induced by cotton ball in mice.The agar dilution method was used to check the minimal inhibitory concentration of Qinlian Liyan Heji on Staphylococcus aureus, Staphylococcus epidermidis, Moraxella catarrhalis, Klebsiella pneumoniae.The microdilution method was used to detect the minimal inhibitory concentration of Qinlian Liyan Heji on group A streptococci, Streptococcal pneumonia and Haemophilus influenzae. Results Contrast to the negative control group, Qinlian Liyan Heji significantly inhibited the increase of blood capillary permeability caused by acetic acid in the middle dose and the high dose groups.In the low dose and middle dose groups, Qinlian Liyan Heji obviously reduced the swelling of plantar in 2, 3, 4, 5 h.In the high dose group, Qinlian Liyan Heji markedly lowered the swelling of plantar in 1, 2, 3, 4, 5 h. Qinlian Liyan Heji significantly reduced the granuloma caused by cotton ball. On the other hand, Qinlian Liyan Heji exerted bacteriostatic effect on the above 7 types of bacteria. Conclusion Qinlian Liyan Heji has effects of anti-inflammation and bacteriostasis.
