ISSN: 1435-1463Keywords: Keywords: Rabbit ; serotonin ; sexual behavior ; penile anesthesia.Source: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Summary. Sexual behavior was evaluated in sexually experienced male rabbits after the administration of different serotonergic drugs. The serotonin1A receptor agonist 8-OH-DPAT, 1 mg/kg, inhibited male rabbit sexual behavior when animals were tested 15 min after subcutaneous (SC) administration of this compound. Lower doses, 0.25 and 0.5 mg/kg, were ineffective at a test 30 min after drug injection. Furthermore, 8-OH-DPAT, 0.25 mg/kg, failed to revert the inhibitory effects upon sexual behavior produced by lidocaine application to the rabbit penis. Stimulation of 5-HT1B/2C receptors by TFMPP, at doses between 0.625 and 2.5 mg/kg, produced a drastic inhibition of sexual behavior when the drug was administered SC 30 min before behavioral observation. Doses below 5 mg/kg were ineffective when given intraperitoneally 15 min before test. When the 5-HT1D/2C receptors were stimulated by the agonist mCPP a reduced number of mounts and ejaculations was observed after the SC administration of 1.25 and 2.5 mg/kg. Similarly, the mixed 5-HT agonist/antagonist lisuride reduced the percentage of rabbits displaying mounting behavior at doses of 0.25 and 0.5 mg/kg SC. All compounds tested produced a clear inhibition of male rabbit sexual behavior independently of the receptor subtype activated. These results are at variance with previous observations in rats where 8-OH-DPAT and lisuride produced a drastic facilitation of masculine coital behavior. Moreover, while the inhibition of male sexual behavior in rats produced by TFMPP and mCPP is associated with a disruption of the execution of this behavior, in rabbits these compounds reduced sexual motivation. These results indicate that the effects of serotonergic drugs on sexual behavior are species specific.Type of Medium: Electronic ResourceURL: -

ISSN: 1435-1463Keywords: Morphine ; naloxone ; methylnaloxone ; loperamide ; sexual behavior ; male rabbitSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Summary The purpose of the present series of experiments was to analyze the effects of morphine and naloxone on sexual behavior in the male rabbit, and to evaluate the role of central and peripheral opioid receptors. Morphine was found to inhibit sex behavior in a dose dependent way. The effects were slight at 5 min postinjection. At 1 hr all aspects of sexual behavior were reduced. This effect lasted at least until 3 hrs postinjection. Subcutaneous (s.c.) injection produced effects at lower doses than intraperitoneal (i.p.) injection. Minimal effective doses were 1.25 and 5 mg/kg, respectively. Naloxone also inhibited sexual behavior. Again, s.c. administration had effects at lower doses than i.p. administration (0.25vs 16 mg/kg). The effects of morphine were reduced but not completely antagonized by several doses of naloxone, independently of whether s.c. or i.p. administration were used. An opioid kappa agonist, bremazocine, inhibited sexual behavior at a low dose (30 μg/kg). It is suggested that the inhibitory effects of morphine may be mediated by the kappa receptor. A peripheral opioid antagonist, methylnaloxone, had no effects by itself and was unable to modify the effects of morphine. It is concluded that the effects of morphine are localized within the central nervous system. This is further supported by the observation that loperamide, a peripheral opiate agonist, had only marginal effects on sex behavior.Type of Medium: Electronic ResourceURL: -

Разультаты указывают на то, что по сравнению с платиной, активность биметаллических катализаторов в несколько раз ниже, в то время как селективностя к гидрогенитическим продуктам увеличивается от 72 до 100%.Notes: Abstract Alumina supported platinum, palladium and bimetallic platinum-palladium catalysts have been investigated in the hydrogenolysis of n-hexane. Results show that, compared with platinum, the activity of bimetallic catalysts is several times lower while the selectivity to hydrogenolytic products increases from 72 to 100%.Type of Medium: Electronic ResourceURL:
