postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
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 ...
