The present research used immunohistochemistry to analyse the detection and localization of NOS isoforms in the ductuli efferentes and epididymis of prepubertal and adult alpaca. In the ductuli efferentes and epididymis of prepubertal and adult animals, nNOS and eNOS were similarly expressed in epithelial lining cells, conversely differences were observed in the immunopresence of iNOS. Our data...

In Iraq. the municipalities are responsible for the production and delivery of drinking water (DW) .The quality of DW in Iraq is greatly deteriorated because of the war operation in this country Objective to study the effects of manganese chloride on histological testes, epididymis and kidney of rats and explore the dose –effects and time effects .The rats are randomly divided into six treatmen...

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 ...

Introduction Acute scrotal pain with or without swelling and erythema in the child or adolescent male should be treated as an emergent condition. The differential diagnosis includes: torsion of the spermatic cord, appendix testis or epididymis, epididymitis/orchitis, hernia, hydrocele, trauma, sexual abuse, tumor, idiopathic scrotal edema (dermatitis/insect bite), cellulitis, and vasculitis (He...

BACKGROUND During epididymal transit, functional and structural modifications leading to full maturation enable male gametes to reach, recognize and fertilize the oocytes. In dogs, little is known on the modifications of spermatozoa during the passage in the epididymis. The aim of this study was to describe the motility, morphology and acrosomal patterns of canine spermatozoa retrieved from the...

The mammalian testis and epididymis are responsible for spermatozoa production and maturation, which contributes to male fertility. Predominantly expressed proteins in the testis and epididymis were suggested to be involved in the key functions or pathways in spermatogenesis and sperm maturation. To further investigate these proteins and their associations with sperm, large protein profiles of ...

Bactericidal/permeability-increasing protein (BPI) is an endogenous antibiotic protein with activity against gram-negative bacteria. In the present study, we examined the expression of BPI in postnatal mouse testes and epididymides as well as the subcellular localization within epididymal spermatozoa. Our results showed that, BPI mRNA was expressed in testis and epididymis independently. Throug...

We present a case of 72-year old man treated from 2007 for superficial bladder carcinoma. Patient had undergone surgical intervention for transitional cell carcinoma of the bladder, followed by BCG therapy. Two years later enlarged right testis and epididymis was observed. A resection was carried out. Histologic examination revealed in epididymis cauda granulomatous infiltration with eosinophil...

The reproductive cycles of lizards, including Tropidurus species, have been widely studied. However, few studies describe in detail the ultrastructure and the epithelial changes in the epididymis. Using histology and trasmission electron microscopy, we show the seasonal changes in the testis and epididymis of the lizard Tropidurus itambere, during its annual reproductive cycle. The reproductive...
