[Sanatorium-resort treatment in a low-mountain region of patients with ischemic heart disease after aortocoronary bypass].

Sanatorium treatment of patients with coronary heart disease performed in Kislovodsk 6-8 months after aortocoronary bypass leads to a substantial improvement of the functional status of patients without anginal episodes and with Functional Classes I and II angina pectoris.

[Mathematical model of light diffraction on red blood cells].

Mathematical model diffraction of laser radiation on red blood smear for population erythrocytes with their normal distribution according to sizes is presented. It was shown during normal distribution of erythrocytes according to sizes that the first maximal pattern diffraction case does not correspond to the medium diameters, as it is given in literature. It was established that the depth of the first maximum is changed depending on the dispersion value according to sizes.

[The use of image recognition methods in evaluating the degree of severity of radiation injury].

The possibility of application of mathematical methods of the image recognition theory for the estimation of radiation damage severity (RDS) is grounded. The application of the method for the RDS estimation according to densito-geometrical parameters of the peripheral blood lymphocytes is described. The decisive rules for the estimation of the RDS within the feature space are developed.
