[Effect of irradiation on the size of the mitochondria in rat cardiomyocytes].
The paper presents the results of studies of the influence of radiation on the sizes of cardiomyocyte mitochondria in rats. Considering the established regularity of subordination of mitochondrial size distribution to the gamma-law on the cardiomyocyte mitochondria, one can judge presumably on their functional state by the variation in the mitochondrial size distribution. This conclusion is confirmed by the relationship between the redistribution of mitochondrial size and the biochemical parameters of their functional activities. It is recommended to evaluate morphometrically the variation in mitochondrial sizes in the course of computer-assisted microscopic investigation of cells for the purpose of assessment of morphological and functional properties of these cellular organellae and the cell as a whole.
