  3. 2. oocytes from follicles larger than 1. 5 - 2. 5mm in diameter had achieved the maximal diameter ( about 130 u m ), the maximal volume of zona pellucida ( zp ), and stopped growth. in the smaller antral follicles, oocyte diameter and zp volume increased with follicular growth. 3

    2 、表面直徑1 . 5 - 2 . 5mm以上卵泡其卵母細胞已經達到最大直徑（約130 m ） ，透明帶體積也不再增加；在此前的有腔卵泡階段，二者均隨著卵泡直徑增加而增加。
  4. Our research used this laser system and its precise measurement software to make a all - round study on the relationship of zona pellucida thickness / hardness variation of human embryos and clinical pregnancy outcome following in vitro fertilization treatment and the application of laser thinning in assisted hatching. the purpose of this study was to try to provide the basic rationale for assisted hatching and an alternative assisted hatching method

    本研究即為應用這種激光系統及其精確的測量軟體，對zpt 、 zptv與妊娠結局的關系、體外培養胚胎透明帶硬度的變化及激光薄化透明帶進行輔助孵出的臨床應用進行綜合研究探討，旨在為輔助孵出的病人選擇、方法選擇提供基礎與臨床理論依據。
  5. Study of zona pellucida dilating assisted method for mouse oocyte enucleation

    小鼠卵母細胞透明帶膨脹輔助去核方法的研究
  6. There are so many molecules involved the fertility, such as : spl7, a mammalian testis - and sperm - specific protein, can specifically bind with zona pellucida, dextran, dextran sulfated, and fucoidin. another germ cell cyritestin is a testis - and sperm - specific protein belonging to the adam family. it has a disintegrin domain at the n - terminal, known as a integrin ligand, that suggests cyritestin could be involved in sperm adhesion and fusion with the egg membrane previous study demonstration

    配子中的許多分子均參與了上述關鍵環節，如在精母細胞、精細胞和睪丸精子中表達，並特異性與卵子透明帶糖蛋白、葡聚糖、糖酐脂結合的精子表面蛋白17 （ sp17 ） ，以及參與識別或與卵子膜上的整合素相互作用的adam家族成員之一的cyritestin蛋白等。
  7. Some interest has been generated in studying the rationale for assisted hatching. some reports suggest that embryos with lower zona pellucida thickness ( zpt ) and higher zona pellucida thickness variation ( zptv ) had a better chance of successful hatching and so the patient become pregnant ; another reports suggest that in vivo aging ; in vitro culture and exposure to ultralow temperature may induce zona hardening and then impair the embryo ability of hatching

    有作者提出胚胎透明帶厚度（ zonapellucidathickness ， zpt ）小的胚胎孵出時阻力減小，而透明帶厚度變化率（ zonapellucidathicknessvariation ， zptv ）高的胚胎由於透明帶上有一個明顯薄的區域而使胚胎易於孵出；還有作者推測病人年齡、體外培養天數的增加及冷凍處理會增加透明帶的硬度，使胚胎孵出困難。
  8. Expression of nonfull - long human zona pellucida - 3 in cho cell with lentiviral vector

    3蛋白慢病毒表達載體的構建及其在中國倉鼠卵巢細胞中表達的研究
  9. As one of the most promising population control tools in the world today, immuno - contraception using zona pellucida glycoprotein antigens, specifically zp3, may be used to control lagurus population

    卵透明帶3 （ zp3 ）蛋白是哺乳動物生殖過程中介導精卵結合的關鍵因子，已被用作免疫不育控制鼠害研究的主要靶抗原。
  10. The recent development of a non - contact 1. 48 rn diode laser system offers an excellent method for the basic research of physical properties of zona pellucida as well as the clinical application of assisted hatching

    一種新型的1 . 48 m二極體激光系統因其精確、快速而為透明帶物理特性的基礎研究及輔助孵出的臨床應用提供了條件。
  11. A low implantation potential of human embryos replaced in the uterus after in vitro fertilization ( ivf ) is a great barrier in assisted reproduction. recently, failure of the embryonic zona pellucida to rupture following blastocyst expansion has been supposed as a possible contributing factor in implantation failure. and then an idea of creating a hole artificially in the zona pellucida, i. e., assisted hatching ( ah ) has been put forward in order to help blastocyst hatching

    體外受精胚胎移植（ invitrofertilization - embryotransfer ， ivf - et ）中胚胎種植潛力較低一直是困擾人們的一個問題，近年來的一些研究認為囊胚擴張后透明帶不破裂可能是種植失敗的一個原因，於是提出人為地在透明帶上打孔幫助胚胎孵出，即輔助孵出（ assistedhatching ， ah ）的思想。
