Salivary Excretion of Lithium: II. Functional Analysis

Abstract
Salivary Li+ was actively secreted by the cat submaxillary gland, inversely to the rate of flow, at concentrations above serum level. Stop-flow studies indicated ductal secretion of Li+ by a HgCl2 and ouabain-sensitive mechanism. Salivary secretion of Li+ did not resemble Na+ but was similiar to K+ secretion.
