  6. Abstract : the early embryo developmental block is a common phenomenon in mammal when embryos are cultured in vitro. many studies of phosphorus, glucose, hypoxanthine and cytoplasmic factors on early embryo developmental block carried out by different methods such as morphology, biochemistry, molecular biology and micromanipulation have been reviewed. the merit and shortcoming were analyzed and the necessity of using simple or components limited media overcoming early embryo developmental block were also reviewed. media that have been shown effective in overcoming early embryo developmental block in mouse, rat, hamster, rabbit, pig, sheep, cattle and monkey were listed

    摘要哺乳動物胚胎在體外培養中普遍存在早期發育阻滯的現象.對此，人們用形態學、生物化學、分子生物學、顯微操作等手段開展了磷酸、葡萄糖、次黃嘌呤和細胞質因素對早期胚胎發育阻滯的影響的研究.本文綜合分析了共培養系統的優缺點.說明了採用完全成分已知的培養液對進行有關研究的必要性.列出了有效運用於克服小鼠、大鼠、倉鼠、兔、豬、羊、牛、猴等動物早期胚胎阻滯的成分已知的培養液的名稱。
  7. 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。
  8. Tungstate competitively inhibits the utilization of molybdenum for the formation of xanthine dehydrogenases.

    鎢酸鹽競爭性地抑制鉬的利用以形成黃嘌呤脫氫酶。
  9. Tea contains, in addition to caffeine, small amounts of two other methyl xanthines, theobromine and theophylline, 3, 7 - dimethy1 and 1, 3 - dimethy1 xanthine, respectively

  10. Using molecular imprinting method, the 1, 3 - dimethylxanthine theophylline, tho molecular recognition membranes, containing an segments as membrane formation sites and aa segments as functional sites, were prepared by the phase inversion technique. here, tho was selected as a template molecule. the hydrogen bonding between aa segments and the tho templates was measured by ft - ir and nmr. the tho templates can be removed from the membrane through washing with acetic acid aqueous solution. the permeation of tho through the membranes is far more than that of 1, 3, 7 - trimethylxanthine caffeine, caf, which demonstrated the function of tho molecular recognition of the membrane. the results also show that the increase of the tho templates concentration in the cast solution caused an increase of tho amounts taken into the copolymer membrane

    Ft - ir及nmr測試結果表明：制備的高分子膜中， tho模板分子和膜中的丙烯酸功能殘基存在著氫鍵鍵合作用。大量的極性醋酸水溶液可抽出膜中的模板分子。 tho溶液和與模板分子具有相似結構的1 ， 3 ， 7 -三甲基黃嘌呤咖啡因， caf溶液的基質透過實驗結果：進入膜結構中tho分子的量遠大於caf分子，這表明制備的高分子膜具有tho分子識別功能。
