The uptake of sugar and amino acids was affected by the presence of cations in the filling solution in both the fishes, Ophiocephalus and Heteropneustes. Under low Na+ concentration, the rate of transport decreased while an increase in Na+ concentration brought about its corresponding increase in both the fishes. Li+ was able to substitute Na+ to some extent in the filling solution in the transport of xylose, glycine and leucine. The replacement of Na+ by Li+ was more successful in xylose transport, in contrast to the transport of glycine and leucine. On the other hand, K+ was not able to substitute Na+ in the transport process. K+ inhibited the transport of glycine but did not that of xylose and leucine.
在月鳢和胡子鲇这两种鱼类中，填充溶液中阳离子的存在会影响糖和氨基酸的摄取。在低钠浓度下，转运速率下降，而钠浓度增加时，这两种鱼类的转运速率都会相应增加。在木糖、甘氨酸和亮氨酸的转运过程中，锂离子在一定程度上能够替代填充溶液中的钠离子。与甘氨酸和亮氨酸的转运相比，锂离子替代钠离子在木糖转运中更为成功。另一方面，钾离子在转运过程中不能替代钠离子。钾离子抑制甘氨酸的转运，但不抑制木糖和亮氨酸的转运。
