( 3 ) incubation of zona - free hamster eggs with spermatozoa pretreated with pmr a ntiserum was associated with a dose - dependent significant reduction in the number of spermatozoa binding to the oolemma, compared with a contraband with a dose - dependent reduction of the fertilization rate and the penetration index. the results indicate that mr of human sperm plays an important role in sperm - oocyte fusion and oocyte activation

    結果顯示： （ 1 ）人精子mr能夠誘發去透明帶金黃地鼠卵母細胞中皮質顆粒的胞吐，並引起卵母細胞膜表面微絨毛形態和數量發生改變； （ 2 ）皮質顆粒胞吐后，其內容物可結合到卵膜表面； （ 3 ）抗mr抗血清預處理精子可抑制精子與卵子的結合與融合，使受精率、穿透指數和結合指數下降，並均有劑量依賴性。以上結果提示，人精子mr在受精過程中起重要作用，其主要作用可能是介導精-卵膜融合併促進卵母細胞的活化。

  8. Multiple electrical stimulations induced higher rates of activation, cleavage and developmental of blastocysts than single one. 3 continuous electrical stimulations ( 10min, interval ) obtained higher rates of activation and developmental than 2 times and 1 time ( 89. 58 %, 20. 59 % vs70. 83 %, 11. 54 % and 60. 42 %, 14. 28 % ; p < 0. 05 ). ( 2 ) ca2 + in electric medium was crucial to mouse oocyte activation when stimulated with electrical pulses. oocytes were activated more easily in a medium with ca2 + than in one without ca2 + by electrical stimulations, but free calcium concentration in electric medium did not affect the activation efficiency of oocytes ( p < 0. 01 )

    脈寬進一步增加並不能繼續升高卵母細胞的激活率；卵母細胞的激活率也隨激活次數的增加而升高，卵子經多次激活處理后，激活率、卵裂率和囊胚發育率都明顯升高，本實驗採用3次連續電脈沖（每次間隔10min ）處理卵子，得到的激活率和囊胚發育率（ 89 . 58 ， 20 . 59 ）顯著高於1次（ 60 . 42 ， 14 . 28 ）和2次處理組（ 70 . 83 ， 11 . 54 ， p 0 . 05 ） 。
  9. In the presence of hx, oocyte maturation to mil and the extrusion of polar body were highly synchronized, the oocytes matured to mil stage were activated in higher rates than oocytes matured without hx, and those oocytes matured exposed to hx for all the 24h showed a high rate ( 55 % ) of spontaneous activation

    Hx存在情況下成熟到m期的卵母細胞排出第一極體時同步化程度高，其孤雌活化能力高於正常成熟卵母細胞， hx作用24h組出現自發激活現象（自發活化比率55 ） 。
