[Nitroxidergic neurons in some nuclei of medulla oblongata in human and rat].

Seven nuclei of medulla oblongata bearing a relation to human and rat bulbar vasomotor center and in which four types of neurons were distinguished by intensity of reaction to NADPH-diaphorase were analyzed. The analysis has shown that majority of human and rat nuclei have similar pattern on nitroxid-positive neuron distribution: neurons with high NO-synthase activity predominate in vasomotor nuclei, and neurons with low one predominate in sensitive nuclei.
