G - gastrula 中文 - EN166

gastrula n.(pl. -lae ) 【動物；動物學】原腸胚。

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 而在est和me同工酶表達上，同源和異源精子激發的胚胎則幾乎沒有差異。對不同精子激發彭澤鯽雌核發育子代的生長效應研究，證實了異精效應的存在，發現海鯉精子是一種激發效果較好的外源精子。

gastrulation
G - banding the gtg banding ( g - banding ) was carried out by the standard trypsin method with slight modification , which works well for protochordate because a good number of reproducible g - bands are consistently obtained from the embryonic cells of late blastulae and early gastrulae of amphioxus b . belcheri tsingtauense G帶型用稍作修改的標準的胰酶顯帶技術，進行gtg帶紋的顯示，它們能較好地顯示頭索動物青島文昌魚的晚期囊胚和早期原腸胚的中期染色體的g帶，并且重復性好。
Recombination gene was cut - down and introduced into the nuclei of oocytes or the cytoplasm of goldfish at one - cell stage via microinjection . the results as follows : ( 1 ) fluorescence was observed from embryo under suitable uv light after microinjection 36 hours . the fluorescent ratio of gastrula embryo period was up to 25 % 采用顯微注射法將這種重組基因轉化1細胞期的金魚受精卵，實驗結果如下： ( 1 )顯微注射后，根據胚胎發育分期，胚胎在顯微注射后36小時開始能在紫外燈下觀察到熒光，原腸期發熒光的胚胎比例為25 ，后期發育熒光率逐漸下降，肌肉效應期后又相對穩定。

The fertil ized egg entered the early gastrula stage in 11h45min , the germ ring appeared , and the oil globules diffused in the plant hemisphere in this stage 11小時45分囊胚開始下包，胚環出現，油球出現重新擴散的現象。
The embryonic shield appeared in 15h , and the fertilized egg entered the middle gastrula stage 15小時出現胚盾， 15小時55分，胚體下包一半。
