THE EFFECT OF SALIVARY GLAND EXTIRPATION UPON RABBIT UROPAROTIN EXCRETION

Abstract

The effect of the extirpation of the salivary glands upon uroparotin excretion in rabbits was investigated over a prolonged period of time. Thus, excretion of uroparotin stopped within about 15 weeks after the removal of both parotid and submaxillary glands together and the excretion also remarkably decreased after the removal of either one. The stopped or decreased excretion of uroparotin, however, was found to be completely restored to a normal level in all experiments over a prolonged period of time after the operation. Furthermore, the uroparotin was excreted temporarily after the administration of a considerable amount of parotin into rabbits in which salivary glands had been extirpated.
