[The ultrastructural localization of NO-synthase NADPH diaphorase in a peripheral nerve and its change in diphtheritic polyneuropathy].
Light and electron microscopy was used to study the distribution and changes of NADPH-diaphorase in the cutaneous nerve biopsy specimens in different periods of diphtheritic polyneuropathy (DP). there was a reduction in the reaction rate of the enzyme in Schwann's cells of the destructively changed nerve fibers and an increase in the remyelinated nerve fibers. The enzyme is located on the nuclear and endoplasmic reticulum membranes and ribosomes. It is suggested that there is an association of the synthesis of nitric oxide with the myelin-producing function of Schwann's cells.
