In isolated segments of the dog and cat renal arteries alkalization of the bathing solution at pH from 6.5 to 8.0 increased the amplitude of contraction and the sensitiveness to noradrenaline. A sharp rise of O2 content induced some increase in reactivity of muscle cells and caused spontaneous rhythmic activity. The results suggest a direct effect of pH and pO2 on the functional characteristics of renal arterial muscles. The effect seems to occur due to reversible changes in intracellular pH.
在犬和猫肾动脉的离体节段中，将浴液的pH值从6.5碱化至8.0会增加收缩幅度以及对去甲肾上腺素的敏感性。氧含量的急剧升高会使肌肉细胞的反应性有所增加，并引发自发性节律活动。这些结果表明pH值和氧分压对肾动脉肌肉的功能特性有直接影响。这种影响似乎是由于细胞内pH值的可逆变化而产生的。
