The Motility of Ram and Bull Spermatozoa in Dilute Suspension
1. Ram and bull spermatozoa suspended in a glucose-sodium chloride solution rapidly lose motility at relatively high dilutions. The substitution of chloride-free diluents does not alter the phenomenon. 2. The rapid immobilization of ram and bull spermatozoa due to high dilution may be partially prevented by the addition of supernatants of either ram or bull semen, although motility is not maint...
متن کاملDistribution of adenosinetriphosphatase activity in ram and bull spermatozoa.
The active transport of sodium and potassium has been demonstrated in dog spermatozoa (Quinn & White, 1967) and the existence of a cation pump, involving a sodium\p=m-\potassiumactivated ATPase has been postulated to account for the gradients of alkali metal ions between the cell and seminal plasma (Quinn, White & Wirrick, 1965). Recently, Uesugi & Yamazoe (1966) have reported the occurrence of...
متن کاملThe Effect of Washing on the Motility and Metabolism of Ram, Bull and Rabbit Spermatozoa
The technique of washing tissues and cells has been widely practised in the field of enzyme chemistry, for removing natural substrates and for demonstrating important components of enzyme systems. In the field of reproductive physiology several authors (e.g. Lardy & Phillips, 1943; Mann, 1945) have used spermatozoa washed in calcium-free Ringer's solution for studying the endogenous metabolism ...
متن کاملO-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...
