  • Title: [Succinate dehydrogenase activity in various parts of the rat heart in systole and diastole].
    Author: Rakhmetov AS.
    Journal: Arkh Anat Gistol Embriol; 1986 Nov; 91(11):23-5. PubMed ID: 3813905.
    Abstract:
    After fixation of the rat heart at the state of systole and diastole, succinate dehydrogenase (SDH) activity has been revealed. In distributions of the muscle fibers according to their optic density, statistic characteristics connected with the first four moments have been taken into consideration. SDH activity is different in five cardiac parts. Individual changeability is more pronounced in the all cardiac parts at diastole. In comparison to the internal one at systole, it is lower in the all parts, and at diastole--in the atria only. The ratio of the internal and individual changeability is in such a state, that it should be taken into account in all statistical calculations, connected with SDH activity determination in cardiomyocytes.
