黄芪桂枝五物汤及其配伍抗炎镇痛的比较研究

Comparative Studies on the Anti- inflammatory and Analgesic Actions of Huang qi Guizhi Wuwu Decoction and Its Compositions

目的探讨黄芪桂枝五物汤和方中不同药对抗炎镇痛的药理作用及该方的配伍规律。方法将该方按药对研究法拆方分组,采用热板法、醋酸扭体法镇痛实验模型,以及二甲苯致小鼠耳肿胀、小鼠腹腔毛细血管通透性、大鼠棉球肉芽肿、大鼠蛋清性关节炎、大鼠佐剂性关节炎等炎症模型,比较不同药对的抗炎镇痛作用。结果全方及方中各药对组对二甲苯、蛋清所致急性炎症有明显抑制作用,对大鼠佐剂性关节炎也有较好的抑制作用,能降低腹腔炎症小鼠的毛细血管通透性,抑制棉球肉芽肿增生,提高小鼠痛阈值,减少醋酸所致小鼠扭体次数。结论黄芪桂枝五物汤有明显的抗炎、镇痛作用;单味黄芪也有一定的抗炎镇痛作用,而方中其他药与黄芪配伍后,均能不同程度地增强黄芪的药效作用。

Objective To investigate the anti- inflammatory and analgesic a ctions of Huangqi Guizhi Wuwu Decoction (HGWD) and its compositions and to study its rule of compatibility.Methods Analgesic action of HGWD and its compositio ns were observed by hot- plate method and acetic- acid- induced body twist me thod. Anti- inflammatory action of HGWD and its compositions were observed on t he models of xylene- induced auricular swelling in mice, celiac capillary perme ability in mice, cotton- induced granuloma in rats, albumem- induced arthritis and adjuvant arthritis in rats.Results HGWD and its drug pairs could inhibit the acute inflammation induced by albumen and xylene and rat adjuvant arthriti, decrease the celiac capillary permeability, inhibit the proliferation of granu loma, increase the pain threshold in mice and reduce the frequencies of body tw ist induced by acetic acid.Conclusion HGWD has significant anti- inflammatory and analgesic actions, so does single drug; Radix Astragali alone, but when Ra dix Astragali is used with the other drugs in HGWD, its effect can be enhanced.
