[Experimental research on the physicochemical action of impulse currents when applied transcerebrally].

Thymocyte function and lipid peroxidation in cell membranes of the cerebral cortex and the myocardium of 72 rats were examined to study the stress-limiting mechanism of 10 and 1000 Hz impulse current effect. The additional measurements were as follows: rat and thymus weight, their proportional relations, thymocyte nuclear population, 11--OCS, thyroid hormones (T3, T4), plasma testosterone and insulin, myocardial and cerebral cortical protein. The animals were immobilized for 6 days in individual tight cages where they had food and water.

[Effect of thyrocalcitonin on mineral metabolism in experimental osteoporosis].

By the method of radioactive indication of ashed specimens of the femur, tibia, jaw bones and molars on a model of experimental osteoporosis in rats it is shown that the degree of mineralization of calcified tissues increases under the effect of thyrocalcitonin (TCT). The hypermineralization of jaw bones and, especially, of molars was attended by a lower 45Ca inclusion in these tissues. The structure of the adrenal cortex, kidneys, pancreas and thyroid returned back to normal under the effect of TCT and with carbohydrate rich nutrition, this occurring against the background of a high 45Ca concentration in these organs.
