稀释液渗透压对绵羊精液冷冻效果的影响   总被引：3，自引：0，他引：3  

曾培坚  王立铭 《中国畜牧杂志》1992,28(4):17-19

本试验对绵羊冻精采用两次稀释时,从调整Ⅱ液中葡萄糖含量和降低甘油浓度两方面,改变稀释液的渗透压,测定冻精效果。先增减糖的比例,配制9-2(对照), 84-1和84-2等试验组,其稀释Ⅱ液渗透压1191,1026、1499mmol/kg,获冻精情期产羔母羊率61.69, 63.31, 54.55(P<0.05)。随后, 以84-1为对照,降低甘油浓度,设3个试验组,即87-2,88-1和88-1a,渗透压相应为747,456,463mmol/kg,冻精情期受胎率1987年84-1,87-2为65.37,67.37;1988年87-2,88-1,88-1a为63.16,62.50,46.55(P<0.05)。试验说明,绵羊冻精采取2次稀释法,第Ⅱ液以4％甘油,渗透压为747mmol/kg时,冻精效果最佳。  相似文献

Fever and acute phase response induced in dwarf goats by endotoxin and bovine and human recombinant tumour necrosis factor alpha     

A. S. J. P. A. M. VAN  MIEKT  C. T. M. VAN  DUIN Th. WENSING† 《Journal of veterinary pharmacology and therapeutics》1992,15(4):332-342

Tumour necrosis factor (TNF), a polypeptide produced by mononuclear phagocytes, has been implicated as an important mediator of inflammatory processes and of clinical manifestations in acute infectious diseases. To study further the potential role of TNF in infectious diseases, recombinant Escherichia coli (E. coli) derived human (r.HuTNF-alpha) and bovine TNF (r.BoTNF-alpha) were intravenously (i.v.) administered in dwarf goats. Rectal temperature, heart rate, rumen motility, plasma zinc and iron concentrations, and certain other blood biochemical and haematological values were studied and compared with the changes seen after E. coli endotoxin (LPS) was administered (dose: 0.1 microgram/kg i.v.). Following a single injection of 4 micrograms/kg of r.BoTNF-alpha, shivering and biphasic febrile response were observed, accompanied by tachycardia, inhibition of rumen contractions, drop in plasma zinc and iron concentrations, lymphopenia, and neutropenia followed by neutrophilia. The i.v. administration of a single injection of 4 micrograms/kg r.HuTNF-alpha induced shivering and biphasic febrile responses, accompanied by anorexia and a similar drop in plasma trace metal concentrations when compared with r.BoTNF-alpha-treated goats. The TNF-alpha-induced symptoms were essentially the same as those that occurred after LPS administration. However, the time of onset of these changes after the injection of TNF-alpha was significantly shorter than after LPS. Moreover, the r.BoTNF-alpha induced a longer lasting neutrophilic leucopenia, less neutrophilia, and a more persistent lymphopenia than after LPS injection. Neither r.BoTNF-alpha nor LPS caused severe haemo-concentration. Furthermore, no cross-tolerance between r.BoTNF-alpha and LPS could be demonstrated. We conclude that both r.BoTNF-alpha and r.HuTNF-alpha induce many of the physiologic, haematologic and metabolic changes that characterize the acute phase response to LPS. The overlapping biological activities of r.BoTNF-alpha, r.HuTNF-alpha and LPS in dwarf goats may indicate that both recombinant tumour necrosis factors have some homology with caprine TNF-alpha.  相似文献
