The changing tendencies of the relative contents of phosphorous contained substances have been detected by in - vivo " p magnetic resonance spectroscopy ( in - vivo " p mrs ) during the whole hatching process. in - vivo ] p mrs proved the catabolism of adenosine 5 ' - triphosphate ( atp ), phosphorous ester and phosphocreatine ( pcr ) when the embryo dead. the results could be used to deduce the conversion of phosphorous contained metabolites during the chicken embryo developed

核磁共振定域氫譜( in - vivohmagneticresonancespectroscopy , in - vivohmrs )對
胚胎發育過程中羊水和蛋白、蛋黃的成分進行了分析;用活體磷譜( in - vivo 』 』 pmrs )的方法分析了在整個
胚胎發育過程中含磷代謝物的相對含量隨時間的變化,表明了磷脂類物質及三磷酸腺苷( atp ) 、磷酸肌酸( pcr )在此過程中的變化及可能的相互轉化的趨勢,
胚胎死亡后的磷譜也證明了磷脂類物質及三磷酸腺苷( atp ) 、磷酸肌酸( pcr )在死亡過程中降解為無機磷的現象。

The main differences in ldh exist in five stages from middle - gastrula to muscle construction, which showed four more bands ( ldh9 ", ldh10 ", ldh 11 " and ldh 12 " ) in the isozyme pattern of embryo activated by heterogeneous sperm than that activated by homogenous sperm

By fluorescence real - time pcr, we found that the expression quantity of jak2 increased along with the development of oocyte we also compared the quantity of jak2 in gv oocytes and 2 - cell embryos nuclear. the quantity of jak2 significantly reduced in 2 - cell embryo nuclear compared with gv oocytes
結果發現,隨日齡的增加, jak2的表達量也隨之增加。本試驗還比較了jak2在gv期卵母細胞和2 -細胞胚細胞核中量的變化。結果發現2 -細胞胚核中jak2的量較gv期明顯降低。
