ON THE RELATION BETWEEN ARTERIAL PRESSURE CHANGES AND THE STATE OF CERTAIN REGULATING MECHANISMS IN THE EARLY PERIODS AFTER IONIZING RADIATION AND THE EFFECT OF WHOLE-BODY ALPHAIRRADIATION ON LIPOLYTIC ENZYME INDUCTION BY CONNECTIVE TISSUE CELLS,

Abstract

It was concluded that: the character and degree of early changes in arterial pressure depend on the radiation dose, its rate, and also on the time which passed from the beginning of irradiation to the measuring of arterial pressure; early changes in arterial pressure have a phase character: after a relatively short period of time from the start of irradiation, the arterial pressure increases, after a longer period its decrease is proportional to the dose; and the early rise in arterial pressure is definitely connected to the reaction of the sympathetic nervous system, and the subsequent drop is tied to the predominant influence of the parasympathetic nervous system. It was also observed that for both an absorbed dose of 0.25 and 0.125 rad over the course of the test, a similar (with negligible differences) stimulating effect of wholebody alpha-irradiation onthe process of induction of lipolytic enzymes in cholesterol granuloma occurred. This documents the favorable effect of the used absorbed doses of alpha-irradiation on lipid metabolism. (Author)
