first oocyte 中文意思是什麼

first oocyte 解釋
初級卵母細胞
  • first : adj 1 最初的，最早的。2 最上等的，第一流的。3 基本的，概要的。4 高音（調）的。n 1 最初，第一；第...
  • oocyte : n. 【胎】卵母細胞。
  1. Rat cumulus - enclosed oocyte ( ceo ) and denuded oocyte ( do ) both spontaneously resume meiotic maturation in vitro, when cultured for 2h, the germinal vesical breakdown percentage of do reaches up to 88 %, and ceos get 53 %. oocytes begin to extrude first polar body 1 ( fb1 ) when cultured for 8h. mouse oocyte spontaneous maturation in vitro can be inhibited by 4mm hypoxanthine ( hx ) or 25um 3 - isobutyl - methylxanthine ( ibmx ). while, 4mm hx can not inhibit the spontaneous maturation of rat oocyte, and the lowest effective concentration of ibmx to inhibit rat oocyle spontaneous maturation in vitro is 50um. treated with the same concentration of ibmx, gvbd percentage of rat ceo is lower than that of do, the results indicat that cumulus cells delay rat oocyte spontaneous maturation and potentate the inhibition effect of ibmx, but it ' s not the case on mouse

    Ceo和do培養8h時都開始排出pb1 ；在卵母細胞成熟抑制模型中， 4mm次黃嘌呤（ hx ）和25 m的異丁基甲基黃嘌呤（ ibmx ）是小鼠卵母細胞成熟的有效抑制劑，但4mm的hx抑制大鼠卵母細胞成熟效果不理想，用hx - m199和hx - mem培養24h ， gvbd率分別為61 ， 81 ，而ibmx有效抑制大鼠卵母細胞自發成熟的最小濃度為50 m ， ibmx可以降低大鼠ceo和do的gvbd率，但ceo中的卵母細胞gvbd率要顯著低於do的gvbd率， 100 m的jbmx處理24h后，大鼠ceo和do的gvbd率分別為24 ， 84 ，提示卵丘細胞的存在可以延遲大鼠卵母細胞的自發成熟，有助於抑制卵母細胞成熟，但在小鼠上ceo和do的自發成熟差異不明顯。
  2. Oogenesis was described briefly and the ways of the formation of yolk granules were explored. at first, eight stages in the oogenesis of the acrida chinensis were distinguished and described respectively, basing on the changes of the oocyte ' s size, chromosomal changes in the nucleus of the oocyte, vitellogenesis and the size of the follicle cells

    在基礎理論方面，本研究首先在光鏡水平對中華蚱蜢卵子發生進行了階段劃分；並以此為依據，用組織化學方法對卵子發生中卵母細胞與濾泡細胞遺傳物質的變化及作用，組成卵黃的生物大分子物質的生成及變化進行了初步研究。
  3. 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
  4. The effect of icsi in the site of the first polar body of oocyte

    第一極體位置對卵胞漿內單精子顯微注射結局的影響
  5. Effects of the first polar body ' s position and morphology in murine oocyte on fertility rate and fertilized egg quality in intracytoplasmic sperm injection

    卵胞漿內單精子注射中小鼠卵細胞第一極體位置和形態對受精率和受精卵質量的影響
  6. The first reports on successful clinical use of round and elongated spermatids for assisted reproduction in 1995 suggest the benefits that the technique of spermatid conception can bring to some patients suffering from otherwise untreatable types of male factor infertility. men with non - obstructive azoospermia ( noa ) can now be treated by using intra - oocyte round spermatid injection ( rosi ) or elongated spermatid injection ( elsi ). spermatids can be retrieved from semen or from testis biopsy specimens

    目前，完全不能產生精子的非梗阻性無精子癥（ non - obstmctiveazoospermia ， noa ）患者可採用卵胞質內圓形精子細胞注射（ roundspermatidinjection ， rosi ）或長形精子細胞注射（ elongatedspermatidinection ， elsi ）治療，精子細胞可從精液或從睪丸活檢組織中獲取。
  7. 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。
