Activity of redox enzymes, and of mediator-inactivated enzymes in the neurosecretory cells of the anterior hypothalamus under hydration and dehydration conditions of the rabbit organism was investigated by the histochemical methods. The activity of the Krebs' cycle enzymes and of the electron transport system responded by an increased activity to dehydration and by decreased one to hydration. The activity of alpha-glycerophosphate dehydrogenase and glucose-6-phosphate dehydrogenase increased as compared to the control in both cases. Changes in the monoamine oxidase activity diminished in dehydration and rose in hydration. As to acetylcholinesterase -- the changes in its activity had a reciprocal character.
