Nimesulide induced histopathological changes in the vas deferens of mice.
AIM Nimesulide, a preferential COX-2 inhibitor has 20 times more selectivity towards COX-2 than that of COX-1. COX-2 selective inhibitors cause frequent nephrotoxicity and hepatotoxicity following their usage. This proposes a physiological role of COX-2 in kidney and liver. Not much attention has been focused on the role of COX-2 with respect to reproduction especially in male reproduction, and...
متن کاملCyclophosphamide Treatment Alters the Contractility of Isolated Rat Vas Deferens.
Influence of cyclophosphamide treatment (40. mg/kg, ip on alternate days for 5 times) was assessed on 1 m mol BaCl2-induced in vitro rhythmic contractions in isolated rat vas deferens. The mean frequency (contractions per min) and amplitude (g tension) of rhythmic contractions were significantly decreased in the tissues isolated from cyclophosphamide-treated rats as compared to the control tiss...
متن کاملA new example of a morphine-sensitive neuro-effector junction: adrenergic transmission in the mouse vas deferens. 1972.
The isolated mouse vas deferens possesses an adrenergic excitatory motor innervation which can be inhibited by low concentrations of morphine (ID50=0.5 muM). This effect of morphine is mediated by specific receptors which are blocked by naloxone. Activation of the morphine receptors inhibits noradrenaline release. It is concluded that adrenergic neurotransmission in the mouse vas deferens diffe...
متن کاملA comparative study on the effects of new opioid compounds and morphine on the contractility of guinea pig ileum and mouse vas deferens
Considering the clinical significance of opioids, especially their application for the treatment of severe painful conditions including cancer pain and the requirement for the synthesis of more specific drugs with lower side effects, this study was conducted to perform a preliminary investigation on six newly developed opioid drugs. Our aim was to introduce drugs that act selectively on the opi...
متن کاملSpinal cord segments controlling the canine vas deferens and differentiation of the primate sympathetic pathways to the vas deferens.
This study was undertaken to explore the spinal cord segments controlling the canine and human vas deferens and differentiation of the mammalian sympathetic pathways to the vas deferens. Thoracolumbar white communicating rami (WCR) were electrically stimulated in the dogs. Stimulation of the 1st, 2nd, 3rd, and 4th lumbar WCR elicited an elevation of intraluminal pressure of the vas deferens in ...
