The N-acetylhexosaminidase components of the ram testis and epididymis.

چکیده
Three and four N-acetylhexosaminidase components, from ram testis and epididymis respectively, have been separated by ion-exchange chromatography on DEAE-cellulose. Although they all have the same molecular weight (approx. 140000) and very similar catalytic properties towards the synthetic substrates, 4-methylumbelliferyl N-acetyl-beta-glucosaminide and N-acetyl-beta-galactosaminide, isoelectric focusing of the individual components showed that each had a distinct pI value. Isoelectric focusing has also been used to demonstrate the occurrence of multiple forms in ejaculated ram semen.

Leptin receptor mRNA expression in Taleshi ram gonads
Leptin is secreted mainly by fat, which is involved in energy metabolism and reproduction. Leptin and itsreceptor (Ob-R) have been detected in human spermatozoa and testis, thus it can be concluded leptin involves in male physiology. The goal of this study was determination of the presence of leptin receptor mRNA in the ram testis, epididymis and spermatozoa by reverse transcription polymerase ...

Background: Breeding soundness evaluation (BSE) is the primary assessment for determining reproductive potential of male animals. This method, however, cannot be used to evaluate semen frequently or to predict future semen quality. Computerized analysis of ultrasonographic images provides information on histophysiological changes in male reproductive organs.We hypothesized that: 1. semen parame...
