Collection and preservation of first polar body of oocyte in mice
小鼠卵母細胞第一極體的採集與保存The first polar body of human oocytes does not help predict the precise location of the spindle
第一極體不能精確定位人卵母細胞紡錘體The influence of the first polar body position at intracytoplasmic sperm injection on fertilization and embryo development
第一極體位置對卵母細胞顯微注射受精后受精和胚胎發育的影響These results indicate that chx at an app ropriate concentration can improve the parthenogenetic development of buffalo oocytes, cb at an appropriate concentration may inhibit the extrusion of the first polar body and increase the proportion of activated oocytes with two pronuclei
結果表明，適當濃度的chx能提高卵母細胞激活效果，適當濃度的cb可抑制卵母細胞第二極體的排出，提高孤雌激活后雙原核的比例。 2The percentage of oocytes cleaved and formed pronucleus in either 0. 625 ( ag / ml or 1. 25ug / ml chx group was significantly higher than the control group ( p < 0. 05 ). however, when the concentration of chx was increased to 5 ug / ml, the cleavage rate and pronuclear formation rate were decreased significantly ( p < 0. 01 )
結果培養在0 . 625和1 . 25 g mlchx的卵母細胞的激活分裂率和總原核形成率明顯高於對照組（ p 0 . 05 ） ，而培養在5 g mlchx的卵母細胞的激活分裂率和原核形成率則極顯著低於對照組（ p 0 . 01 ） 。At the beginning, the cytoplasm is evently distributed, then it is polar - distribution and at last it only remains between the apical cap and the sperm nucleus. during the period of spermatogonium, chromatin in the nucleus is in the shape of conglomeration and the nucleus is big ( i. e. the proportion of the nucleus to cytoplasm is bigger than spermatocyte ). at the stage of primary spermatocyte, chromatin accumulates to sc complexity. the nucleus of the mature sperm takes the shape of a plate and filmentous chromatins exist freely in uncondensed nucleus
精子發生過程中，細胞器由少到多，到最後解體；細胞質從均勻分佈，到精細胞期極性分佈，最後殘留于成熟精子的頂帽和精核之間；細胞核在精原細胞期，染色質異固縮，胞核大，即核質比大於后續的精母細胞；在初級精母細胞中，染色質凝聚為sc復合體，到成熟精子，精核呈碟狀，染色質呈絲狀游離于非濃縮的核中。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 ） 。Presently, the scientist have made out some successes by using biotechnology and molecuology, for example, planting out regeneration shoots, culture suspended cell in ferment tank, screening mutant tissue with high content of flavonoids, cloning and sup - expression of key enzyme, restraining derivative pathway by anti - dna or anti - rna and inducing genetic transformated hairy root
通過培養水母雪蓮的發狀根將是獲得雪蓮類黃酮極有前途的方法，目前還是一項待填補的空白。發根農桿菌（ agrobacteriumrhizogenes ）是一種革蘭氏陰性土壤細菌，細胞內有200kb左右的雙鏈閉環dna ? ri質粒（ rootinducingplasmid ） 。At first, the vrl - cdna plasmids were transformed into tg1 r. coli to enlarge vrl - cdna ; then the plasmids were extracted and cut off with enzymes ; subsequently, vrl - cdnas were transcribed into vrl - inrna by t7 or sp6 polymerase in vitro, following vrl - mrnas were injected into xenopus laevis oocyte to express into vr1 receptor protein ; at the end the vrl + - oocytes were tested by double electode voltage clamp
這項實驗中，我們首先將大白鼠vr1 - cdna質粒轉入大腸桿菌中進行擴增，然後提取質粒並酶切，然後在體外轉錄成vr1 - mrna ，接著將vr1 - mrna注射到非洲爪蟾卵母細胞中表達為蛋白質受體，建立了實驗模型細胞，最後用雙微電極電壓鉗檢測此模型細胞。An analysis of rhys ' blood showed the few lymphocytes he possessed came from his mother and the supply had been cut off when breast - feeding ended
