The normal male external genitalia include the testicles with the epididymis attached posteriorly and the vas deferens arising from this. This case describes an anatomical variation of this normal anatomy not previously reported in the literature. A 17-year-old boy presented with symptoms of intermittent testicular torsion and underwent scrotal exploration. On the left side there was a bell-cla...

Three different types of isolated nerve-synapse preparations, guinea pig ileum, rat vas deferens and toad heart, were used to investigate the physiological activity of Huwentoxin-I, a neurotoxin from the venom of the spider Selenocosmia huwena. The twitch response of isolated guinea pig ileum induced by electrical stimulus can be inhibited by HWTX-I. After blockage, contraction of the ileum can...

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...

Concentrations of mono- and divalent cations in the testis, three different regions of the epididymis and the vas deferens of lizard, M. carinata were determined. The concentrations of Na+, K+ and Ca2+ increased gradually from testis to vas deferens. However, no significant variation in the levels of Mg2+ was observed between testis and anterior epididymis, and between posterior epididymis and ...

Recurrent epididymitis and a history of anorectal malformation (ARM) may be secondary to an ectopic vas deferens to ureter described as persistent mesonephric duct syndrome. This is a case of a child with ARM found to have bilateral ectopic ureter to vas connection. The histopathology specimen here would suggest this is an ectopic ureter to vas. In a child with ARM that is undergoing nephrectom...

BACKGROUND Insufficient vas length for performing a tension-free vasovasostomy is a problem occasionally encountered by microsurgeons. Herein we evaluated utilization of a non-vascularized vas deferens autograft in a rat model. METHODS Segments of isolated vas deferens, 2.5 cm in length, were used as bilateral autografts in 15 rats. Each autograft was implanted between the two transected ends...

Aluminium is a blocker of voltage sensitive cakcium channels which intere the body from different soueces.this ion interferes with biological function of Ca++ion.because GnRH synthesis,secretion and spermatogenesis on vas deferens and epididymis sperm count and weight of these organs in male rats.the study was performed on four group of rats(n=49),in whom the arcuate nuleus was bilateraly cannu...

The biotin-avidin immunoperoxidase staining method and antisera against highly purified porcine relaxin were utilized to localize relaxin in the male genital tract. Formalin-fixed tissue specimens from the prostate gland, the testis, epididymis, vas deferens and the seminal vesicle were studied. Specific relaxin immunoactivity was seen in the glandular epithelium of the prostate and also in the...
