title: Electrolytes, protein, and lactate dehydrogenase isozymes of parotid saliva in mineralocorticoid-treated rats.
abstract: Small quantities of parotid saliva were obtained from 7 of 11 rats in which hypokalemia was induced by treatment with deoxycorticosterone acetate (DOCA). Thirst in the treated rats was indicated by an increase in water consumption. A decrease of 28% in plasma potassium levels indicated that the DOCA-treated rats had become hypokalemic; chloride decreased 6-7% while sodium was unchanged. Saliva showed significant increases in potassium and protein and a decrease in sodium; lactate dehydrogenase-2 and -4 bands appeared darker on the electrophoretic profile. These changes are relevant to the clinical manifestations and diagnosis of hypokalemia.
