Abstract
Aortic smooth muscle sodium efflux was studied in normal rats undergoing salt restriction or salt loading. Sodium efflux rate constant was not changed by salt loading but fell significantly with salt restriction. This change was not associated with a fall in blood pressure. These studies show that smooth muscle sodium transport can be influenced by dietary salt intake but do not support the concept that salt loading leads to the inhibition of the vascular smooth muscle sodium pump.
摘要
在进行限盐或高盐饮食的正常大鼠中研究了主动脉平滑肌钠外流。高盐饮食并未改变钠外流速率常数，但限盐使其显著下降。这种变化与血压下降无关。这些研究表明，平滑肌钠转运可受饮食中盐摄入量的影响，但并不支持高盐饮食会导致血管平滑肌钠泵受抑制这一观点。
