目的 研究利尿合劑的抗炎鎮(zhèn)痛及體外抑菌作用，為臨床用藥提供科學的理論依據(jù)。方法 采用二甲苯致耳腫脹實驗、冰醋酸致小鼠扭體反應實驗、冰醋酸致小鼠腹腔毛細血管通透性增加實驗及福爾馬林致痛實驗，觀察利尿合劑高、中、低劑量組（以生藥計18.0、9.0、4.5 g/kg）的抗炎鎮(zhèn)痛作用；采用K-B紙片擴散法研究利尿合劑對金黃色葡萄球菌和大腸桿菌的體外抑菌作用。結(jié)果 利尿合劑高劑量組可明顯減輕小鼠耳廓腫脹度（P<0.01），高、中、低劑量明顯減少冰醋酸致小鼠扭體反應次數(shù)（P<0.01），明顯抑制冰醋酸致小鼠腹腔毛細血管通透性增加（P<0.05、0.01），顯著降低福爾馬林致痛實驗的第I時相的疼痛強度（P<0.01），對第Ⅱ時相的疼痛強度沒有明顯影響；利尿合劑對金黃色葡萄球菌和大腸桿菌的抑菌率分別為95.04%、37.44%。結(jié)論 利尿合劑具有較好的抗炎鎮(zhèn)痛作用，對金黃色葡萄球菌和大腸桿菌具有體外抑菌作用。

Objective To investigate the analgesic and anti-inflammatory effects of diuretic mixture and its bacteriostasis effect in vitro, and to provide scientific basis for clinical application.Methods Ear swelling test induced by xylene, twisting reaction test induced by acetic acid, capillary permeability increase in abdominal cavity of mice induced by acetic acid, and pain test induced by formalin were used to observe the analgesic and anti-inflammatory effects of diuretic mixture at high, middle and low doses (crude drug 18.0, 9.0, and 4.5 g/kg). Bacteriostatic activities of diuretic mixture were tested by K-B paper disc diffusion method.Results Diuretic mixture alleviated ear edema in mouse model at high dose (P<0.01). Diuretic mixture at high, middle, and low dose could effectively decrease the twisting reaction (P<0.01), inhibit capillary permeability (P<0.05 or 0.01), and ease the ache degree of mice induced by formalin in the first phase (P<0.01), but there was no significant difference in the degree of pain intensity of phase II. The inhibitory rates of diuretic mixture on Staphylococcus aureus and Escherichia coli were 95.04% and 37.44%, respectively.Conclusion Diuretic mixture has significant effects on analgesia and anti-inflammation and against S. aureus and E. coli in vitro.
