目的:研究五酯胶囊(wuZhi-capsule,WZ)对环孢素(cyclosporin A,CsA)在大鼠小肠吸收的影响。方法:三组大鼠分别以CsA试液、含WZ100 mg·L~(-1)的CsA试液、含WZ200 mg·L~(-1)的CsA试液进行在体肠段吸收实验,HPLC法测定CsA浓度。结果:与单用CsA相比,回肠段合用WZ组CsA吸收率明显降低,空肠段合用WZ组CsA吸收无明显变化。结论:WZ对CsA小肠吸收有抑制作用。
Objective: To study the effect of wuZhi-capsule (WZ) on the intestinal absorption of cyclosporin A (CsA) in rats. Methods: CsA solution containing CsA of WZ100 mg · L -1 and CsA solution containing 200 mg · L -1 of WZ were used to perform intestinal absorption experiments in vivo. HPLC Determination of CsA concentration. RESULTS: Compared with CsA alone, CsA absorption in the ileum combined WZ group was significantly lower than that in CsA alone. There was no significant change in CsA absorption in the jejunal WZ group. Conclusion: WZ can inhibit CsA intestinal absorption.
