Different amount of copies in different tissues attribute to the different density of positive signals . the result of the experiment suggested that the transgenic animals can be produced by spermatozoa - mediated gene transfer after the entrapment of liposome . and because the exogenous dna occurs losing the segments . partly integration , or existin g outside of genome dna , the rate of chimerism is relatively high 結果表明： ( 1 )脂質體包裹外源基因轉染精子的方法，可將外源基因導入受精卵中，能夠獲得轉基因動物，并得到了較高的轉基因陽性率； ( 2 )精子攜帶的外源dna的整合過程是隨機的，在受精過程和胚胎早期分化過程中可能發生了片段丟失、不完全整合或游離于基因組存在而產生嵌合體。 |

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，并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，并均有劑量依賴性。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-卵膜融合并促進卵母細胞的活化。 |

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于mr在精卵融合中的作用，本文采用改良后的甘露糖-瓊脂糖凝膠親和層析法分離純化人精子mr ，并將提純的人精子甘露糖受體( purifiedmannosereceptor , pmr )作用于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。 |

However , kit protein doesn “ t exist in oogenesis after birth . there are also c - myc positive protein granules in the spermatomeres from metaphase i to telophase ii , in the spermatozoa and in the secretory cells of the spermatheca . c - myc protein expresses not in the normal follicles , but in the follicular cells of the apoptotic ones Myc在處于減數分裂的中期至末期的精母細胞的細胞質或細胞核內呈陽性表達，在減數分裂后形成的精細胞和受精囊囊壁的上皮細胞的細胞質內也有陽性表達：但在出生后的卵子正常發生過程中無陽性表達，然而在凋亡卵泡的濾泡細胞的細胞質內有陽性表達。 |

Must we accept the view of empedocles of trinacria that the right ovary the postmenstrual period , assert others is responsible for the birth of males or are the too long neglected spermatozoa or nemasperms the differentiating factors or is it , as most embryologists incline to opine , such as culpepper , spallanzani , blumenbach , lusk , hertwig , leopold and valenti , a mixture of both 我們究竟應該接受特利納克利亞的恩培多克勒的說法，即認為男子的誕生決定于右卵巢272另外一些人則主張是在月經后的時期，還是應該認為被放置過久的精子或精蟲乃是決定性別的重要因素？ |

Different from mammals , the early embryos of fish can not be preserved for the long period at the very low temperature ( - 196 ) . therefore , three methods were usually applied to cryogenic preservation of the fine and rare species of fish : 1 ) perserving fish spermatozoon in cryogenic condition . researchers have had systematically studied on this technique for many years , and this technique has been utilized in application and made a lot of effects ; 2 ) combining with the techniques of cell engineering ( nuclear transplantation and electric fusion etc . ) , and through the process of culturing histiocyte of fish , cryopreservation and re - culture after thawing , carrying out somatic cell breeding of fish . the past studies showed that the nucleolus of somatic cells of fish have totipotency 多年來，國內外學者對各種魚類精液的冷凍保存進行了大量的系統研究，目前這項技術已達到實用水平，并日益發揮作用；二是對魚類培養的組織細胞冷凍保存，通過魚類細胞的培養、超低溫凍存、解凍后再培養過程，結合細胞工程技術(如核移植、電融合等)進行體細胞育種；大量的研究結果表明魚類體細胞核具有發育的全能性，隨著細胞培養技術、細胞工程技術日益發展成熟，完全具備實現魚類物種種質長期保存的理論基礎和技術條件。 |

Of the eons of geological periods recorded in the stratifications of the earth : of the myriad minute entomological organic existences concealed in cavities of the earth , beneath removable stones , in hives and mounds , of microbes , germs , bacteria , bacilli , spermatozoa : of the incalculable trillions of billions of millions of imperceptible molecules contained by cohesion of molecular affinity in a single pinhead : of the universe of human serum constellated with red and white bodies , themselves universes of void space constellated with other bodies , each , in continuity , its universe of divisible component bodies of which each was again divisible in divisions of redivisible component bodies , dividends and divisors ever diminishing without actual division till , if the progress were carried far enough , nought nowhere was never reached 隱藏在大地的洞穴里和能移動的石頭底下蜂巢和土墩子中那無數微小的昆蟲類的有機生物：微生物病菌細菌桿菌精子憑著分子的親和之凝聚力而粘在一根針尖上那幾萬幾億幾兆個多不勝數肉眼看不到的微小顆粒人類的血漿是一個宇宙，群集著白血球和紅血球，每個血球又各自形成一個空虛的宇宙空間，群集著其他球體各個球體連續性地也是由可分割的構成體形成的宇宙，各個構成體又可以分割成為幾個能夠進一步分割的構成體。就這樣，分子與分母實際上在并未分割的情況下就不斷地減少了。如果這個過程延續到一定時候，就永遠在任何地方也不會達到零。 |
