[The distribution of nitric-oxide synthetase in the cells of the rat cerebral cortex].

In the experiment performed in mature male Wistar rats using histochemical method of nitric oxide synthase revealing it was shown that the enzyme may be produced in brain by neurons, glial cells, epitheliocytes of vascular plexuses of lateral ventricles and endotheliocytes of different caliber vessels. Distribution of nitric oxide synthase in neurons and their processes indicate the possibility of both post- and presynaptic localisation of the enzyme.
