胆酸盐在食物脂肪代谢中超重要作用,这是大家公认的。但目前有一些研究证明,胆酸盐通过对细胞受体膜离子通道和Na—KATP酶的作用,影响细胞输运行为的进程。 为此我们以上海郊区产中华大蟾蜍离体皮肤为材料,皮肤的跨皮电位(Transepi-thelial Potential)为探针,着重研究了胆酸盐对皮肤上皮细胞透性和跨皮电位(以下简称TEP)变化的规律。所用动物雌雄兼 Cholic acid salt in food fat metabolism is an important role, it is generally accepted. However, there are some studies that show that cholate can affect the process of cell transport behavior through the action of membrane ion channels on cell receptors and Na-KATPase. To this end, we used the isolated skin of Bufo bufo gargarizans from Shanghai suburbs as the material and the transepi-thelial potential of the skin as a probe to study the effects of cholate on the permeability of the skin epithelium and the transmembrane potential (hereinafter referred to as TEP) changes in the law. Used animals both male and female
