Histochemical reactions for NADPH-diaphorase (NADPH-d) were used to study the dynamics of NO synthesis activity in the cervical nuclei of the rat brain after i.v. administration of morphine hydrochloride. In normal conditions, NADPH-d activity was found in neurons in all the cervical nuclei. Acute and chronic administration of morphine at different doses(More)
Using histochemical reaction demonstrating NADPH-diaphorase (NADPH-d), the dynamics of NO synthesis was studied in the rat brain raphe nuclei following intravenous injection of morphine hydrochloride. In normal conditions NADPH-d activity was demonstrated in neurons of all raphe nuclei. Acute and chronic administration of morphine in different doses (0.5(More)
Systemic administration of diacetylmorphine considerably reduced the number of NADPH diaphorase-positive (NO-synthesizing) neurons in rat brain raphe nuclei. This effect was blocked by naloxone. In animals with the withdrawal syndrome NO-ergic activity in raphe neurons increased and surpassed the normal.
