[Succinate dehydrogenase activity of the retina and occipital lobe of the brain during emotional stress].
The emotional stress induces changes in redox processes in the visual analyzer at the level of the succinic acid transformation in the Krebs cycle. The stress evokes a particularly sharp decrease in the succinate dehydrogenase activity in the retina under conditions of dark adaptation whereas in the occipital lobes under the same condition a considerable intensification of the succinic acid oxidation is observed. Stress action under ordinary conditions of the day and night change is accompanied by the succinate dehydrogenase activation in the visual analyzer. However, the light load increases the enzyme activity in test animals the same way as in intact animals.
