[Localization of NADPH diaphorase in the central nervous system of the bivalve mollusc Cristaria tuberculata].
By histochemical and electron histochemical methods, NADPH-diaphorase was discovered in neurons and their processes of all ganglia of the central nervous system (CNS) of Cristaria tuberculata. Small cells predominated among neurons containing NADPH-diaphorase. Ultrastructural localization of the enzyme was detected on the perinuclear membrane and membranes of endoplasmic reticulum, cytoplasmic granules and cytosol. In the majority of cells, the reaction product was commonly found in cytoplasmic granules-cytosomes. We studied peculiarities of synaptic contacts between nitrogen oxide synthesizing neurons and their processes. In active synaptic areas, a sediment was discovered on the internal surface of pre- and postsynaptic membranes.
