Boar rete testis fluid and luminal contents from nine epididymal segments were collected for analysis. From proximal to distal, segments were designated A, B, C (caput), Da, Db, Ea (corpus) and Eb, Fa, Fb (cauda). Concentrations of sperm, protein and soluble sperm membrane glycoprotein S2P3 were lowest in the caput epididymidis (region A) and highest in the proximal corpus epididymidis (region ...

Grasslands of Iran are encountered with a vast desertification and destruction. Some legumes are plants of forage importance with high palatability. Studied legumes in this project are Onobrychis, Medicago sativa (alfalfa) and Trifolium repens. Seeds were cultivated in research field of Kaboutarabad (33 km East of Isfahan, Iran) with an average 80 mm. annual rainfall. Plants were cultivated in ...

In a previous study we showed that the administration of gossypol to rats for 34 days caused 2 types of modification of the epididymis: (1) the secretion of carnitine and inositol were reduced in the fluid, (2) the spermatozoa lost their motility and showed major morphological changes (head-flagella dissociation). We wished to clarify the early effects of gossypol on the epididymis. Sprague Daw...

High-resolution two-dimensional polyacrylamide gel electrophoresis analyses have indicated that several major boar sperm plasma membrane polypeptides (PMPs) increased in concentration during maturation in the epididymis. To investigate this further, monoclonal antibodies (MAbs) to two of these PMPs/glycoproteins referenced as 4.85 and 5.0 and polyclonal antisera (PCA) raised against PMP 5.0 wer...
