SUMMARY This study was conducted to shed light on to the factors contributing to fertilizing ability of the caput epididymal spermatozoa. In this content, it should be stated that seminal plasma am! epididymal fluid of most mammalians contains inhibitory factors connected to spermatozoa surface. To do this, components of different regions of mouse epididymis centrifuged and a given volume o...

However, this procedure involves relatively high radiation dose. The purpose of thi...

The effects of unilateral efferent duct ligation, bilateral castration or testosterone replacement on the spermatocrit and inositol concentrations in luminal fluid removed by micropuncture from the rat epididymis were investigated. By 5 days after efferent duct ligation, there were substantial falls in the spermatocrit in the caput and corpus, but no change in the cauda. After 7 days there was ...

In the present study, we developed a novel method to analyze the calcium (Ca2+) signal in living slices of mouse caput epididymides by applying calcium imaging on Fura-2-loaded vibratome slices. The data revealed that in epithelial cells of mouse caput epididymides, ATP induces a rapid Ca2+ signal that is sustained after 60 sec. Preincubating the sections in Ca2+-free medium in the presence of ...

BACKGROUND The epithelium lining the epididymis provides an optimal acidic fluid microenvironment in the epididymal tract that enable spermatozoa to complete the maturation process. The present study aims to investigate the functional role of Na(+)/HCO(3)(-) cotransporter in the pH regulation in rat epididymis. METHOD/PRINCIPAL FINDINGS Immunofluorescence staining of pan cytokeratin in the pr...

Caput epididymis proteins from control, pairfed and zinc deficient (ZD) wistar weanling albino rats after 2-, 4-, 6- and 8-weeks were examined using SDS-PAGE followed by densitometric scanning of the gels. In comparison to the control and pairfed rats, ZD rats displayed new proteins. These included a Mr 42 kDa from 2ZD, Mr 47.5, 27.5, 23.2 and 16.0 kDa from 4ZD and Mr 87 and 14.2 kDa from 6ZD g...

In this contribution, the conservation status assessment of three vascular plants are presented according to IUCN categories and criteria. It includes Oryza rhizomatis D.A.Vaughan Saxifraga facchinii W.D.J.Koch at a global level Helianthemum caput-felis Boiss. regional level.

We have investigated the toxic effects of trichloroethylene (TCE) on the epididymis and epididymal sperm in mice. Mice were exposed to TCE (1000 ppm) by inhalation for 6 h/day for 5 days/week for 1 to 4 weeks. Segments of the epididymis (caput, corpus and cauda) were examined by light and electron microscopy. At the light microscopic level, degeneration and sloughing of epithelial cells were ev...

Rat sperm isolated from the caput and caudal epididymis and the vas deferens were subjected to multiple partition in aqueous two-phase systems. The technique was used to reveal heterogeneity of a sperm population with respect to particular surface properties. Sperm from all three regions gave broad distributions indicative of heterogeneous cell populations. Greatest heterogeneity was observed f...
