[Cytophotometric study of catecholamines and energy metabolism enzymes in the neurons of the rat celiac plexus during cold and emotional stresses].

The content of catecholamines and activity of the energy metabolism enzymes in neurons of the celiac ganglia during cold and emotional stress were studied histochemically using a computer analysis. It was shown that acute short-term cooling increased catecholamine fluorescence intensity, as well as succinate dehydrogenase and lactate dehydrogenase activity in the celiac ganglia neurons, whereas short-term emotional stress induced no changes in the fluorescence intensity and enzyme activity.
