spasmolytic effect of vitis vinifera leaf hydroalcoholic extract on rat's isolated vas deferens
introduction: many reports have shown that the grape (vitis vinifera) seed extract induces antioxidant, hypotensive hypolipidemic, and vasodilatory effects. we have recently shown the relaxatory effect of grape leaf extract on rat's aorta, ileum, uterus and frog's heart rate and contractility. the objective of this study was to investigate the spasmolytic effect of vitis vinifera leaf hydroalco...
AIM To access beta-endorphin levels in serum as well as seminal plasma in different infertile male groups. METHODS Beta-endorphin was estimated in the serum and seminal plasma by enzyme-linked immunosorbent assay (ELISA) method in 80 infertile men equally divided into four groups: non-obstructive azoospermia (NOA), obstructive azoospermia (OA), congenital bilateral absent vas deferens (CBVAD)...
We evaluated a biodegradable graft for reconstruction of rat vasa deferentia with long obstructed or missing segments. A total of 47 Sprague-Dawley rats underwent bilateral vasectomy and were divided into groups according to length of the vas deferens affected (0.5, 1, 1.5 cm). After 8 weeks, poly-(D,L-lactide) (PDLA) grafts were used to reconnect the vas deferens. Grafts and adjoining vasa def...
Insertion of a copper wire into the vas deferens of male rats released 4 micrograms of copper in themid portion of the vas deferens in two days time. In urethral and epidymal segments of the vas deferens copper released was less than one microgram. The present study demonstrates that the in vivo effects of 4 microgram of copper in 2 days time in the vas deferens are enough to induce antifertili...
Among rat peripheral tissues examined, Ins(1,4,5)P(3) receptor binding is highest in the vas deferens, with levels about 25% of those of the cerebellum. We have purified the InsP(3) receptor binding protein from rat vas deferens membranes 600-fold. The purified protein displays a single 260 kDa band on SDS/PAGE, and the native protein has an apparent molecular mass of 1000 kDa, the same as in c...
