Abstract

Histochemical methods were used to study the activity of oxidoreductases and enzymes inactivating mediators in the neurosecretory cells of the anterior hypothalamus during hydration and dehydration in rabbits. Enzymes of the Krebs cycle and of the electron transport system were shown to respond by increased activity to dehydration and by reduced activity to hydration. Activity of α-glycerophosphate dehydrogenase and glucose-6-phosphate dehydrogenase was increased compared with the control in both cases. Monoamine oxidase activity was reduced during dehydration but increased during hydration; changes in acetylcholinesterase activity were in the opposite direction.
