  1. Materials and methods the mouse, golden hamster and human sperm were incubated with endotoxin in different concentration for different time to get capacitation, respectively, and ar was induced by progesterone after capacitation, then the rates of capacitation and ar were detected by chlortetracycline ( ctc ) and hoechst 33258 fluorescent staining method. the medium was with endotoxin in different concentration in sperm - oocyte fusion step during ivf, then the fertilization rate was observed. the 1 - cell, 2 - cell and zona - free 2 - cell mouse embryos were incubated in the medium with endotoxin, then the rate of blastocysts was recorded

    方法取小鼠精子10份、金黃地鼠精子6份、人新鮮精液標本10份及人冷凍精液標本9份，分別與不同濃度內毒素共孵育進行體外獲能和孕酮誘導的頂體反應，應用金黴素和dna結合的熒光染料hoechest33258雙重熒光染色法檢測精子的獲能率和頂體反應率；小鼠體外受精實驗的精卵結合環節培養液中加入不同濃度的內毒素，觀察受精情況並記錄受精率；取小鼠1 -細胞胚胎、 2 -細胞胚胎和去卵透明帶2 -細胞胚胎，與不同濃度內毒素共孵育進行體外培養，觀察體外發育情況並記錄囊胚率。
  2. Eeffect of different concentrations of progesterone on ovine sperm capacitation in vitro

    孕酮對綿羊精子體外獲能的影響
  3. Objective the present study was to investigate the effects of endotoxin on capacitation and acrosome reaction ( ar ) of mouse, golden hamster and human sperm, on the sperm - oocyte fusion in mouse, and on the development of 1 - cell, 2 - cell and zona - free 2 - cell mouse embryos in vitro. the purpose was to definite the committed step and the mechanism during in vitro fertilization ( ivf ) on which endotoxin affected, and to distinguish the sensitivities to endotoxin of three developmental systems of mouse embryos. all these data would provide the reference to clinical and laboratory quality control

    目的研究內毒素對小鼠、金黃地鼠及人精子的體外獲能和頂體反應、小鼠精卵結合及小鼠1 -細胞、 2 -細胞和去卵透明帶2 -細胞胚胎體外發育的影響，探討內毒素影響體外受精結局的環節及可能的機制，確定三個體外培養系統對內毒素的敏感性，以期為臨床和實驗室質量控制提供參考。
  4. Endotoxin made capacitation of mouse, golden hamster and human sperm increase in advance, and the effect on frozen - thaw human sperm was stronger than fresh human sperm. 2

    內毒素使小鼠、金黃地鼠和人精於獲能的高峰期提前，且對人冷凍精於體外獲能的影響比人新鮮精子更加顯著。
  5. These results suggest that cftr in sperm may be involved in the transport of hco3 - important for sperm capacitation and that cftr mutations with impaired cftr function may lead to reduced sperm fertilizing capacity and male infertility other than cbavd

    研究結果顯示，精子的cftr功能為碳酸氫根的傳輸，促使精子獲能；而cftr基因突變引致功能失效，會降低精子授精能力，這是先天性無輸精管以外另一導致男性不育的可能因素。
  6. Cftr inhibitor or antibody significantly reduces the sperm capacitation, and the associated hco3 - dependent events. they also found that the fertilizing capacity of the sperm obtained from heterozygous cftr mutant mice is also significantly lower as compared to that of the wild - type

    Cftr抑制劑或抗體能有效減低精子獲能，及相關的碳酸氫根依賴反應；研究人員又證實cftr突變老鼠，其精子授精能力大大比野生型老鼠為低。
  7. This review will discuss the role of epithelial sodium channel ( enac ) and the cystic fibrosis transmembrane conductance regulator ( cftr ) in regulating the fluid volume and composition of the reproductive tract and their importance in various reproductive events such as sperm capacitation and implantation

    本綜述著重探討了上皮細胞鈉離子通道和囊性纖維化跨膜電導調節體對雌性生殖道內液體容量和成分的調節以及它們在不同生殖事件，比如精子獲能及著床中的重要作用。
  8. Bsp ( boyine seminal plasma ) protein is the cardinal protein in bovine sperm, which can combine with choline or phosphycholine and then adhere to the surface of sperm to promote the sperm capacitation induced by heparin and high density lipoproteins ( hdl ). moreover, bsp protein can combine with heterogeneous collagen, fibrinogen, heparin, calmoduline, igf - ii and apoa - i. bsp can also inhibit the migration of cholesterol on the sperm membrane

    前言bsp （ bovineseminalplasma ）蛋白是牛精漿中的主要蛋白質， bsp蛋白可以與膽堿或磷脂膽堿結合，黏附於精子表面，可促進由肝素、 hdl等誘導的獲能過程，另外bsp蛋白與不同來源的膠原、纖維蛋白原、肝素、鈣調蛋白、 igf - 、 apoa -等結合， bsp蛋白還可抑制精子胞膜上的膽固醇遷移，這些都暗示了bsp蛋白在精子胞膜的脂類代謝及調節精子的獲能以及頂體反應方面發揮重要作用。
  9. In order to investigate the role of mannose receptor ( mr ) of human sperm, the zona free hamster eggs were pre - incubated with purified mr ( pmr ) isolated from motile human sperm by mannose - agarose gel affinity chromatography. the ultrastuctural alteration and cortical granule exocytosis of the eggs were then observed by transmissian electron microscope and tritc - lca immunofluorescence microscope, respectively. the mice were immunized with pmr and the antiserum was raised. after capacitation and induction of the acrosome reaction, the human spermatozoa and oocytes were incubated with the antiserum. then the sperm penetration assay was undertaken

    為了進一步探討人精於mr在精卵融合中的作用，本文採用改良后的甘露糖-瓊脂糖凝膠親和層析法分離純化人精子mr ，並將提純的人精子甘露糖受體（ purifiedmannosereceptor ， pmr ）作用於去透明帶的金黃地鼠卵母細胞，運用透射電子顯微鏡技術和羅丹明偶聯的兵豆凝集素（ tritc - lca ）免疫熒光標記技術觀察pmr對卵子的影響。
  10. Co - culture of sperm with endometrial cells treated with antisense oligonucleotide against cftr, or with bicarbonate secretion - defective cf epithelial cells, resulted in lower sperm capacitation and egg - fertilizing ability

    相反，如果用缺乏cftr的細胞，或者是cftr發生突變的細胞，精子便不能有效獲能。
  11. Many reports suggested that the high cholesterol concentration of sperm membraneis a barricade of capacitation and in many mammals such as bull, ray and human. it had been corroborated there is cholesterol efflux while capacitation

    Bsp蛋白還可促進精子胞膜上的膽固醇外流，目前已有報導認為精子胞膜上高濃度的膽固醇是妨礙獲能的一個重要原因。
