【摘要】 采用离体肠管实验法,将鸡空肠置于盛有40mL生理溶液的麦氏浴皿内,然后分别加入不同剂量的苍术、白术、茯苓及二术茯苓散水煎液,使溶液终浓度分别为3.75、7.50、15.00、22.50mg/mL,以观察对离体肠管张力的影响。结果表明,二术茯苓散和其组分药苍术、茯苓水煎液均能抑制肠管的运动,使鸡离体空肠收缩张力和舒张张力降低,收缩振幅减小;白术水煎液对鸡离体空肠平滑肌有兴奋作用,可使肠管张力增强,收缩振幅增大。各种水煎液随着浓度的增加其影响增强。更多还原

【Abstract】 Isolated chook’s jejunum was put in the magnus’ bath with 40 mL physiological solution,then added vary dosage decoction of Rhizoma atractylodis,Rhizoma atractylodis macrocephalae and Erzhu fuling san to make the final concentration to 3.75,7.50,15.00 and 22.50 mg/mL,observing the effects on the tension of isolated intestine. The results indicated that Erzhu fuling san and the decoction of Rhizoma atractylodis and Rhizoma atractylodis macrocephalae could both restrain the movement of intestine,reduce its contract and diastole tension and contract swing,the decoction of Rhizoma atractylodis macrocephalae could excite the unstriped muscle and enhance the tension and swing of chook’s isolated jejunum. All kinds of the decoction could enhance the effects with the concentration increasing.更多还原
