豬腹部火器傷腸管穿透后肝臟功能和形態的變化The results were as follows : ( l ) the pre - incubation of pmr induced the exocytosis of the cortical granules ( cgs ) in the oocytes and reduced the quantity of the microvillus on the surface of oocytes ; ( 2 ) the matrix of cg might migrate to the surface of plasma membrane of oocytes after pmr pre - treatment. ( 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。It can be observed from experiment that the final whole deformations of the tubes take on the shapes of " v ", and " w " in certain condition. the local dents of the tubes are obvious. the critical velocities and plugging modes of penetrations can be obtained
