A new class of unimodular perfect sequences of length p/sup s/, where p is a prime, is proposed. An explicit secondary construction is provided. This construction includes most of the previously known unimodular perfect sequences of length p/sup s/ as special cases. Also the proposed construction is extended to sequences with autocorrelation over /spl… (More)
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)
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.
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)
