卵周隙

高剂量组卵母细胞卵周隙内出现颗粒比例也明显高于低中剂量组（40.2%vs17.5%、23.2%，P<0.01）。

Moreover , percentage of oocytes with perivitelline space granularity were significantly higher than those in intermediate dose and low-dose groups ( 40.2 % vs 17.5 % , 23.2 % , P < 0.01 ) .

在显微操作仪的控制下，将分离后的单个卵裂球注入去核次级卵母细胞的卵周隙。

The blastomeres separated from the embryos were injected into the perivitelline space of enucleated secondary oocytes under the control of micromanipulator .

卵周隙随卵母细胞在体内的老化逐渐增大。

The width of PVS was increased gradually with aging of oocytes in vivo .

为了研究受精过程对慢病毒感染胚胎的影响，本试验采用卵周隙显微注射的方法，用低滴度的病毒（106TU/ml）分别感染小鼠受精卵和卵母细胞。

In order to study the influence of fertilization on the infection of embryos by lentivirus , lentivirus of low titer ( 106 TU / ml ) were microinjected into perivitelline spaces of mouse fertilized eggs and oocytes .

方法：用显微注射法把小鼠附睾头和附睾尾精子注入卵母细胞的胞质内或卵周隙进行显微受精。

Methods : ICSI and SUZI were employed to obtain the assisted fertilization of mouse sperm from caput epididymidis and cauda epididymidis .

因此推测，卵母细胞的第一极体形态和卵周隙大小反映了卵母细胞的成熟度，受精前观察卵母细胞第一极体和卵周隙的形态可以预测ICSI后的受精能力。

Present data indicates that , oocyte morphology , including the shape of the first polar body and the size of perivitelline space , reflects the maturity of the oocytes and may have a predictive value on the ability of fertilization following ICSI .
