In this study, we investigated the antipsychotic-like effect of methanolic extract of Mitragyna speciosa leaf (MMS) using in vivo and ex vivo studies. In vivo studies comprised of apomorphine-induced climbing behavior, haloperidol-induced catalepsy, and ketamine-induced social withdrawal tests in mice whereas the ex vivo study was conducted utilizing isolated rat vas deferens preparation. Acute...

Studies on the beneficial effects of vitamins E and D supplementation on functions of caput and cauda epididymides, their spermatozoa, vas deferens and seminal vesicle of sodium fluoride (NaF) treated (10 mg/kg body weight) male mice (Mus musculus) were carried out. The NaF treatment resulted in significant decrease in the body and epididymis weight but those of vas deferens and seminal vesicle...

1. When administered subcutaneously HS-599, a new didehydroderivative of buprenorphine (18,19-dehydrobuprenorphine), produced a long-lasting antinociceptive response in rats. Its potency exceeded twice that of buprenorphine. In the tail-flick test it acted as a full agonist but in the plantar test only as a partial agonist. Whereas the mu-opioid antagonists naloxone and naltrexone antagonized H...

INTRODUCTION Congenital absence of the vas deferens (CUAVD) is a rare clinical entity, usually discovered accidently during surgical procedures of the urogenital zone, CUAVD has the prevalence of 0.5-1.0% in male population and it is associated with various forms of congenital genitourinary malformations like renal agenesis. we present a case of a 21 years old, male, managed in our private hosp...

Chronic antidepressant administration increases neurotrophin levels in the central and peripheral nervous system, leading to an increase of neuronal sprouting, reestablishment of neural networks and neurotransmitter levels. Injured peripheral nerves regenerate at very slow rates. However, the recovery of the hypogastric nerve in rodents after injury is significantly improved with neurotrophin a...

1. The effect of lysergic acid diethylamid (LSD) on the response to field stimulation in vitro of the rat vas deferens and anococcygeus muscle was examined. 2. LSD in concentrations from 10(-9) to 10(-6) M caused an increase in tone or rhythmic activity in both tissues, effects identical to those produced by guanethidine or tyramine. The motor effects of all three drugs were abolished by phento...
