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

ABSTRACT

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.
