[Role of mitochondrial swelling in the energetic effectiveness of intact myocardial cells (according to electron microscopy data)].
The myocardium of the left and the right cardiac ventricles was studied at various seasons on 20 rabbits. There was found a distinct seasonal dynamics of a number of quantitative indices of electronograms. In particular, there was found a relationship between the coefficients of energy efficacy of the mitochondria (integral value--calculated by multiplying the mitochondrial area by the number of mitochondrial cristae) and the mitochondrial area. With increase of the latter to 0,85 mc2 this relationship is positive and linear. With further swelling of the mitochondria this relationship disappears, however.
