ABSTRACT
Lithium compounds administered into rats' organisms in euthermia elicited accelerated urinary excretion of physiological cations, especially the Na and K ones. Homeothermic organisms in hypothermia, returnig from hypothermia and in posthypothermia showed considerable caliuresis with delayed excretion of Na during the following days. By way of gastric filling lithium load (in a form of water LiCl solution, with concentration of 0.2 n and the amount of 3.0 ml/100 cm2 ger body surface) administered to rats in deep hypothermia (17 degrees C - 19 degrees C measured high in the sigma), recovering of hypothermia (4 h) and in posthypothermia (20 h) did not elicit delayed natriuresis but efficiency of lithium and hypothermia had been summarised (clearly enhanced natriuresis and extremely enhanced caliuresis as a summarised efficiency).
