2.Objective:To study the effect between Ethinylestradiol combined Rivanolum and Misoprostil and sole Rivanolum for stoping the metaphase and late pregnancy.
3.Human Peripheral blood exposed with tritiated water at variousdoses for 54 hr was examined to observe the chromosome and chromatid abe-rrations at metaphases in the first mitosis of lymphocytes.
4.Metaphase 1 Homologous pairs move together along the metaphase plate: the paired homologous chromosomes align along an equatorial plane that bisects the spindle.
6.The LH gets to work on the oocyte that's been dormant inside the follicle, and triggers it to finally start dividing again — getting it to complete meiosis I and move on to metaphase II.
LH 开始作用于卵泡内休眠的卵母细胞,并触发它最终再次开始分裂——让它完成减数分裂 I 并进入 II。
