Cholinergic mechanisms in cocaine-induced genital reflexes in paradoxical sleep-deprived male rats
(Elsevier B.V., 2004-03-01)In view of the fact that paradoxical sleep deprivation (PSD) modifies cocaine-induced genital reflexes (penile erection [PE] and ejaculation [EJ]), the aim of this study was to address the interaction of cholinergic agents ...

The effect of apomorphine on genital reflexes in male rats deprived of paradoxical sleep
(Elsevier B.V., 2003-11-01)Drugs that stimulate dopamine (DA) systems can stimulate sexual arousal in male rats and humans, and previous work has shown that cocaine enhances genital reflexes [penile erection (PE) and ejaculation (EJ)] in rats deprived ...

Effect of sildenafil (Viagra®) on the genital reflexes of paradoxical sleep-deprived male rats
(Associação Brasileira de Divulgação Científica, 2007-11-01)Since there is evidence that paradoxical sleep deprivation (PSD) elicits penile erection (PE) and ejaculation (EJ), and that the erectile response of rats is mediated by nitric oxide, the present study sought to extend the ...

Effects of morphine or naloxone on cocaine-induced genital reflexes in paradoxical sleep-deprived rats
(Elsevier B.V., 2004-11-01)The involvement of opioidergic neurotransmission in the modulation of genital reflexes induced by paradoxical sleep deprivation (PSD) and cocaine in rats was the aim of the present study. Morphine (0, 1, 5 and 10 mg/kg) ...

Effects of paradoxical sleep deprivation and cocaine on genital reflexes in hyperlipidic-fed rats
(Elsevier B.V., 2005-08-01)The present study was designed to investigate the effects of a hyperlipidic diet (HD) on penile erection (PE) and ejaculation (EJ) induced by cocaine in paradoxical sleep deprived (PSD) rats. Secondly, we aimed to verify ...

Effects of paradoxical sleep deprivation on genital reflexes in five rat strains
(Elsevier B.V., 2006-02-01)This study examined the effects of cocaine on genital reflexes in paradoxical sleep-deprived (PSD) male rats of five strains since it has been demonstrated that this drug enhances genital reflexes in Wistar PSD rats. At ...

Effects of progesterone blockade over cocaine-induced genital reflexes of paradoxical sleep-deprived male rats
(Elsevier B.V., 2005-04-01)Paradoxical sleep deprivation (PSD) enhances cocaine-induced genital reflexes (penile erection [PE] and ejaculation [EJ]) in male rats and induces a significant increase in progesterone concentration. As progesterone ...

Inhibitory effect of GABAergic drugs in cocaine-induced genital reflexes in paradoxical sleep-deprived male rats
(Elsevier B.V., 2004-06-01)The aim of this study was to seek whether GABAergic drugs were involved in the action of cocaine on spontaneous genital reflexes (penile erection-PE, and ejaculation-EJ) of paradoxical sleep-deprived (PSD) male rats. After ...

Noradrenergic system interacts with genital reflexes induced by cocaine in paradoxical sleep-deprived male rats
(Amer Psychological Assoc, 2005-04-01)Different doses of alpha-1, alpha-2, beta-1, and beta-2 adrenoceptor agonists or antagonists were administered to paradoxical sleep-deprived (PSD) rats prior to cocaine administration. Metboxamine reduced the percentage ...
