最小浓度 meaning in Chinese
cmin minimum concentration
minimum concentration
Examples
- 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培养8h时都开始排出pb1 ；在卵母细胞成熟抑制模型中， 4mm次黄嘌呤( hx )和25 m的异丁基甲基黄嘌呤( ibmx )是小鼠卵母细胞成熟的有效抑制剂，但4mm的hx抑制大鼠卵母细胞成熟效果不理想，用hx - m199和hx - mem培养24h ， gvbd率分别为61 ， 81 ，而ibmx有效抑制大鼠卵母细胞自发成熟的最小浓度为50 m ， ibmx可以降低大鼠ceo和do的gvbd率，但ceo中的卵母细胞gvbd率要显著低于do的gvbd率， 100 m的jbmx处理24h后，大鼠ceo和do的gvbd率分别为24 ， 84 ，提示卵丘细胞的存在可以延迟大鼠卵母细胞的自发成熟，有助于抑制卵母细胞成熟，但在小鼠上ceo和do的自发成熟差异不明显。
