The effect of ouabain on membrane potential and flagellar wave in ejaculated bull spermatozoa.

نویسنده

  • A McGrady
چکیده

Ejaculated bull spermatozoa were exposed to various concentrations of ouabain to ascertain the effect on membrane potential, intracellular concentrations of sodium and potassium and motility. Membrane potenital, measured by electrophysiological methods, decreased. Intracellular potassium decreased and intracellular sodium increased. Progressive motility decreased. In addition, the motility change produced by ouabain was identified as a decrease both in beat frequency and in wave amplitude.

Cadmium as an etiology of sperm dysfunction in Holstein bulls

Oxidative stress has been identified as a crucial factor leading to male infertility largely due to peroxidativedamage to the sperm cell membrane. Cadmium (Cd) is a widespread environmental pollutant and oneof the well-known reproductive toxicants. Because of its long biological half-life (10–30 years), Cdaccumulates in the biological systems. The present study was designed to assess the concen...

P-142: Effects of A Synthetic Antioxidant (4-Hydroxy Tempo) Additive to The Semen Extender on the Ejaculated Spermatozoa Characteristics before and after Freezing in Water Buffaloes (Bubalus Bubalis)

Background: Semen cryopreservation is the most important section of artificial insemination programs; it allows preservation of semen fertility for a long time. Materials and Methods: The aim of the present study was to detect the effect of in vitro supplementation of 4-hydroxy Tempo on fresh and frozen spermatozoa quality of buffalo bulls. Five healthy buffalo bulls (5 ejaculates from each bul...

O-12: Studies on Sequestration of PDC-109 Protein on Cryodamage and In Vitro Fertility of Crossbred Bull Spermatozoa

Background: Plasma membrane of the spermatozoa interacts with and is altered by abundant seminal PDC-109 present in their immediate milieu in vivo with damaging effect in a time- and concentration- dependent manner. Therefore we hypothesized that sequestration of detrimental protein from ejaculates would be beneficial for cryopreservation of sperm cells. To this aim we evaluated the effect of s...

Effect of various levels of catalase antioxidant in semen extenders on lipid peroxidation and semen quality after the freeze-thawing bull semen

The objective of this study was to evaluate effect of different concentrations of catalase in two extenders on motility, viability and lipid peroxidation bull spermatozoa during semen freezing process. Thirty ejaculates collected from ten Holstein bulls were pooled and evaluated at 37 °C. Pool ejaculated was split into two main experimental groups, 1 and 2. In experiment 1, specimen was dilute...
