Relation of the Parotid Gland to Serum Protein and Malnutrition

Abstract

1. The serum A/G decreases after the removal of the parotid glands in dogs and rabbits.2. The injection of parotin in doses of 10mg. per kg. of body weight raises the serum A/G of normal rabbits, but does not change the blood sugar level. We assert, therefore, that the parotid gland participates in serum protein.3. We discussed the possibility that the cause of parotid enlargement of malnutrition could be explained by our experiments.4. Parotin causes leukopenia of normal rabbits on the beginning of injection and thereafter marked leukocytosis.5. Parotin action of leukocytosis in normal white rats does not depend upon the existence of their adrenal cortexes. We would like to express best thanks to Dr. Y. Takahashi for the technical advise in the serum A/G determination and to Drs. Akira Ikushima and H. Momoi for the examination with the Tiselius electrophoresis.
