Abstract
Summary and Conclusions
A constant rate of potassium excretion, dissociated from filtered load, occurring after salyrgan administration suggested a tubular secretory mechanism located, presumably, in the distal tubule. The presence of such a mechanism has been demonstrated by the intravenous administration of hypertonic KC1 solutions which yielded rates of potassium excretion considerably above the rates of filtration of potassium at the glomerulus.
