The control of salt preference in the adrenalectomized rat.

Abstract

Three experiments are reported. In the first, adrenalectomized animals deprived of salt until a severe salt need had developed showed an immediate high intake of 3% NaCl solution, as contrasted to the slower increase in preference for this solution by animals that had been allowed access to it immediately after their adrenalectomy. The second experiment demonstrated "that a decrease in the internal salt-level results in an elevation of the preference-aversion function at all concentrations . . ‥ The third experiment showed that adrenalectomized animals markedly increase their intake of 3% NaCl when being fed an ion-exchange resin which permits intestinal absorption of only about 50% of the sodium entering the gut."
