Abstract

The diuretic amiloride, an almost specific inhibitor of sodium transport in animal cells and tissues, appears to produce a number of effects in the alga Hydrodictyon reticulatum. At 1 mmol/l concentration it markedly reduces the influx of sodium ions (but not their active outflux), the influxes of potassium, chloride as well as of bicarbonate ions, and causes a profound decrease in the plasmalemma membrane potential. This plurality of inhibitory effects suggests that individual transport processes in the alga are mutually coupled.

摘要

利尿药氨氯吡脒是动物细胞和组织中钠转运的一种几乎特异性的抑制剂,它似乎对网状水网藻产生多种效应。在1毫摩尔/升的浓度下,它显著降低钠离子的内流(但不影响其主动外流)、钾离子、氯离子以及碳酸氢根离子的内流,并导致质膜膜电位大幅下降。这种多种抑制作用表明藻类中的各个转运过程相互关联。
