A quantitative assessment of T3 pool was performed in patients with malignant tumors of the esophagus, stomach, pancreatic head, rectum and colon as well as in patients with chronic gastritis, peptic ulcer and benign stomach tumors. A high T3 pool deficiency was noted in patients with malignant GIT tumors. It was assumed that such a deficiency was indicative of profound disorder of hormone supply of tissues which could be regarded as an endogenous factor of predisposition to the development of malignant neoplasms.

Stimulation of the rabbit anterior hypothalamus reduced the amount of reticulocytes in the blood, decreased the hematocrit, redistributed the intrarenal blood flow reducing the blood supply of the renal cortex. Stimulation of the posterior hypothalamus led to an increase in the reticulocytes amount and an isolated increase in the blood supply of the cortical nephrones' glomeruli. No changes of the plasma erythropoietic activity occurred. The data obtained suggest the hypothalamus-induced changes of the hemodynamics (in bone marrow and kidneys particularly) as one of the possible hypothalamic influences upon the erythrone.
