Glutamic dehydrogenase and glutamic-oxalacetic transaminase were assayed of rat and dog tissues, such as thyroid, adrenal cortex and medulla, anterior and posterior pituitary, liver, kidney, heart and cerebral cortex.It was observed that activity of these enzymes was generally lower in endocrine tissues than in nonendocrine ones.Enzymic activity of the thyroid was the lowest among all the tissues examined.Liver and kidney were found highly active.Interrelationships between these findings and the physiological functions of some of these tissues were discussed with special reference to thyroid physiology.
