The effect on the transmural potential from adding glucose under different conditions of sodium and calcium has been studied in rat and laying-hen intestine in vitro with the technique for measuring Transmural Potential Difference. The glucose, in sodium-free mediums, has no effect on the Transmural Potential Difference in rat intestine, whether calcium be present or absent. As to hen intestine, the PDt increased when calcium is present in the medium, both in the absence and presence of sodium. Glucose absorption was also determined in vivo by using mediums with/without calcium. In rat intestine glucose absorption was not affected by the presence of calcium, while its presence enhanced glucose absorption in hen intestine.
利用测量跨壁电位差的技术，在体外对大鼠和产蛋鸡的肠道进行了研究，探讨了在不同钠和钙条件下添加葡萄糖对跨壁电位的影响。在无钠培养基中，无论有无钙，葡萄糖对大鼠肠道的跨壁电位差均无影响。对于鸡肠道，无论有无钠，当培养基中存在钙时，跨壁电位差都会增加。还通过使用含/不含钙的培养基在体内测定了葡萄糖吸收情况。在大鼠肠道中，葡萄糖吸收不受钙的影响，而在鸡肠道中，钙的存在增强了葡萄糖吸收。
