[Changes in the catecholamine level and energy metabolism of the myocardium in rats during cold and emotional stress].
The catecholamine content in adrenergic plexuses and the oxidative enzyme activity (succinate dehydrogenase, lactate dehydrogenase) during cold and emotional stress were studied histochemically in the rat myocardium. An acute short-term cooling led to an increase in the catecholamine fluorescence intensity and succinate dehydrogenase activity, whereas a short-term emotional stress resulted in a decrease in both these parameters.
