[ECONOMIC EFFICIENCY TECHNOLOGIES DIAGNOSIS OF ISCHEMIC HEART DISEASE BY MAHNITOTOKARDIOHRAFIYI].

The article is devoted to clinical--economic analysis of modern diagnostic technology--magnetocardiography by analyzing the "cost-effectiveness". Economic effectiveness of diagnosis of coronary artery disease using magnetocardiography in terms of cost/effectivness is shown. The economicaly optimal sequence of several noninvasive methods for diagnosis of coronary artery disease is defined.

[The biological action of physical factors in the critical periods of embryogenesis].

The critical period in a chicken embryonic development (the 10-13-th days of incubation) is revealed under total electromagnetic radiation. This external factor is a physiologically active irritant which can influence functional state of the brain. The increased absorption of electromagnetic energy takes place in this incubation period.

[Shortening of the life span in an experiment with chronic external gamma-irradiation. The structure of mortality].

The paper submits the statistical analysis of data on the mortality structure obtained by the experiment with chronic external gamma-irradiation within a wide range of dose rates. The cumulative mortality rate was a function of time. The authors discuss whether the shortening of life span resulting from chronic exposure to gamma-radiation is or is not specific.

[Pathologicoanatomic changes during combined radiation and chemical injuries fo rats].

Pathoanatomical analysis, carried out after the combined effect of whole-body irradiation and pesticides of different classes over 5 days in doses of 1/4 LD50/30 and 1/4 LD50, respectively, did not exhibit any changes other than those caused by each of the factors applied separately.
