Histoenzymatic characteristics of the adrenal medulla 60 days after ending exposure to detergents

: Histochemical and histoenzymatic features of the adrenal medulla were studied 60 days after the end of an exposure to detergents. The findings obtained, point to an increase in the quantity of nucleic acids, and an intensified activity of nonspecific esterases as well as the cytochrome oxidase in rats maintained in a detergent manufacturing plant. The activity of isocitrate dehydrogenase was reduced in the control animals, as well as the activity of lactate dehydrogenase and isoenzyme "S" lactate dehydrogenase. The activity of isoenzyme "F" lactate dehydrogenase, glucose-6-phosphate dehydrogenase and succinate dehydrogenase is greater in the group which had been exposed to detergent influence. An active engagement of medullocytes is emphasized at this term of the experiment. The agent applied elicits a disturbance in the metabolism of glucose and a number of other substances. The author is of the opinion that an altered and stimulated synthesis and secretion of catecholamines takes place in the adrenal medullocytes under the experimental conditions which were investigated. The neuroendocrine system has been engaged in a series of processes which had been studied.
