It is now possible to store turkey semen for 4 to 24 h without appreciable loss in fertility and hatchability. Optimum conditions for 24 or 48 h storage have not been fully determined. Development of new storage media, allowing the insemination of very low numbers of spermatozoa, may provide interesting possibilities regarding the use of superior sires. This study was conducted to evaluate effe...

In previous work...

This study investigates the interactions between a porcine lung surfactant (PLS) extract and distilled water, saline solution or Ringer solution. The phases which coexist in equilibrium with water or electrolyte solutions were analysed by X-ray diffraction and cryo transmission electron microscopy (cryo-TEM). A lamellar phase with a structure unit consisting of double bilayers was observed in w...

Metabolism and tension were examined in single fibers of the semitendinosus muscle of Rana pipiens at 15 degree C after excitation-contraction uncoupling by stretch and hypertonicity. Interrupted tetanic stimulation at 20 HZ for 150 s, of control fibers in isotonic Ringer at a rest sarcomere length (SL) of 2.3 micrometers, resulted in a steadily declining tension, stimulated glycolysis, and sig...

LEE, J, S. Contraction of villi and fluid transport in dog jejunal mucosa in vitro. Am. J. Physiol. 221(2) : 488-495. 1971.-An intestinal mucosal membrane preparation permitting simultaneous determination of the fluid transport rate and a microscopic examination of villi was employed. The occurrence of sustained villus shortening was invariably associated with diminution or abolition of fluid t...

Distribution of flow and red cells between the efferent (epibranchial) and venous pathways was examined with an isolated perfused gill adapted to collect the two effluents separately. Gills from two fish species (Ictalurids) with abundant prelamellar arteriovenous anastomoses (AVAs) were compared with those of the trout which contain few AVAs. The gills were perfused with Ringer or Ringer conta...
