葛根芩连汤配伍抗腹泻药效实验研究

目的:通过对葛根芩连汤各配伍与抗腹泻药效之间关系来探讨其配伍规律.方法:运用正交设计方法,用墨汁为显色剂,小鼠小肠推进率为指标;用番泻叶造成小鼠腹泻模型,以腹泻次数为指标,观察葛根芩连汤各配伍与药效变化之间的关系.结果:葛根芩连汤配伍降低小肠推进率的影响中,以黄连与炙甘草作用为主,葛根与黄芩能拮抗黄连的作用,炙甘草则增强黄连的作用.减少腹泻小鼠DI,主要作用药物为黄连,黄芩拮抗黄连,葛根能增加黄芩的作用,而炙甘草与黄芩黄连配伍后能增强黄连的作用.结论:在葛根芩连汤的抗腹泻药效中,其最佳组合为黄连炙甘草.

Experimental study on anti-diarrhae effect of Gegenqinlian Decoction and its compounds

AIM: To investigate combination principle of Gegenqinlian Decoction through experiment of anti-diarrhea. METHODS: Propelling rate of mouse's small intestine was selected as index on the condition of ink as colour reagent, diarrhea frequence served as second index for orthoganal design on the basis of mouse's diarrhea induced by senna. RESULTS:Coptis chinensis franch and Glycyrrhiza uralensis fisch and reduce drive rate. Scutellaria baicalensis Georgi and Pueraria lobata(wild) ohwi had counteracter against Coptis chinensis franch's effect, while Glycyrrhiza uralensis fisch could enforce Coptis chinensis franch's effect.as to DI, Coptis chinensis franch had anti-diarrhea effect. Scutellaria baicalensis Georgi had counteracter against Coptis chinensis franch's effect, Pueraria lobata(wild) Ohwi could enforce Scutellari, baicalensis Georgi effect, but Glycyrrhiza uralensis fisch could enforce Coptis chinensis's effect after compounding with Scutellaria baicalensis Georgi. CONCLUSION: ~Among the combinantion of Gegenginlian Decoction, as to the pharmcological effects on anti-diarrhea, the best compound is Coptis chinensis franch and Glycyrrhiza uralensis fisch.
