title: [The acid phosphatase, aminopeptidase and glutamate dehydrogenase activity in the nodose ganglion neurons in emotional stress].
abstract: Cell bodies of cardiovascular receptors localized in the rabbit ganglion nodosum exposed to experimental emotional stress were studied histochemically. Two groups of animals were selected for investigation. Rabbits of one group had almost unchanged arterial pressure and small increase in heart rate under emotional stress, while animals of the other group were characterized by strongly marked disturbances of blood circulation leading to the lethal exit at the end of experiment. Activities of lysosomal enzymes--acid phosphatase and aminopeptidase--in the nodose ganglion neurons of the first group rabbits were found to be on the control level, the activity of mitochondrial enzyme, a glutamate-dehydrogenase, was slightly increased, whereas in the second group rabbits all the enzymes studied were significantly activated. A possible correlation between the metabolic changes found in the neurons and the type of hemodynamic changes is discussed.
