Following the puncture of zona pellucida with two holes by injection pipette that contained donor nuclei or cells, the injection pipette was pulled back to the perivitelline space while the negative pressure was increased in the holding pipette until the polar body and karyoplasm were wiped off completely. Then a reconstructed embryo was completed by the direct injection of the donor nucleus or cell without pulling out the injection pipette.
首先以预先吸有细胞核或细胞的注射针在固定于持卵针上的卵母细胞透明带上穿刺两个孔,然后一边缓慢地将注射针回拔至卵周隙中,一边逐渐增加持卵针中的负压,直至极体与目标核质被完整吸入持卵针中而完成去核,最后在不拔出注射针的情况下直接注射细胞核或完整细胞进而完成重构胚的构建。

objective the effects of anthocyanin pigment from maize purple plant on resisting lipid peroxidation were investigated.methods the inhibition of anthocanin pigment from maize purple plant was examined in vitro that autcoxudation of lecithin liposome system induced by fe2+.50 mice were randomly divided into 5 groups.vehicle and different dose anthocyanin pigment from maize purple plant were given respectively,and then experimental injury of mice liver was induced to make use of bromobenzene and the content of mda was determined in liver homogenate.results the inhibition rates of anthocyanin pigment from maize purple plant on linoleic acid oxidation was higher that of ascorbic ascorbic acids.the content of mda in homogenate in middle and high dose of pigment were significantly lower than that in low dose and the injured control group.there were no significat differences in the content of mda in homogenate between low dose group and injury control group.conclusion the anthocyanin pigment from maize purple plant have the capability to resist lipid peroxide.
目的 探讨玉米紫色植株色素抗脂质过氧化的作用。方法体外实验测定玉米紫色植株花色苷色素在fe2+引发的卵磷脂脂质体体系中抗氧化活性。体内实验,取50只小鼠随机分成5组,分别给予溶媒和不同剂量的色素,然后采用溴代苯致实验性肝损伤,测定肝匀浆的丙二醛含量。结果在由fe2+引发的卵磷脂脂质体体系中玉米紫色植株色素对脂质过氧化有明显的抑制作用,抑制率随样品的浓度增高而增大,并且明显优于抗坏血酸。在溴代苯致小鼠实验性肝损伤模型实验中,中、高剂量组的丙二醛含量均低于损伤模型组。低剂量组和损伤模型组比较丙二醛含量差异无统计学意义。

The cleavation rates and blastocyst development rates of cloned embryos were used to assess the efficiency of different operational procedure. Finally, the best combination of operational procedure, that the spindle-viewer system was used for oocytes enucleating, and donor cell was electrofused into ooplasm by electrical pulse (1.9 kV/cm, 10 ms, two) to reconstruct bovine cloned embryos.
以核移植胚胎的卵裂率、囊胚发育率作为检测指标,对不同的方法所获得的克隆胚胎的卵分裂率与囊胚发育率进行比较,最后筛选获得1个优化的牛体细胞核移植操作程序,即采用Spindle view系统对牛卵母细胞进行去核操作,将供核体细胞注射到卵周隙,然后通过电融合法将供体核引入去核卵细胞质(电融合参数为1.9 kV/cm,脉冲时程10 ms,方波2次间隔2 s)。

The results showed that : 1 During nonbreeding season, the giant panda′s ovary was still rich with large and small follicular oocytes, and the large follicular oocytes could be matured in vitro; 2 The mean diameter of the oocytes was (141±6.7)μm and lots of cortical granules contained in the cytoplasm of oo...
结果表明∶(1)在非繁殖季节,大熊猫卵巢中小腔及大腔卵泡卵母细胞仍较丰富,其大腔卵泡卵母细胞可在体外培养成熟;(2)大熊猫的卵母细胞平均直径为(141±6.7)μm ,其胞质富含卵黄颗粒;(3)自配 PandaI I号获能液(含丙酮酸钠、肾上腺素等)可使大熊猫精子有效获能;(4)大熊猫卵母细胞体外受精后,经培养可观察到第2 极体,有的受精卵开始发生卵裂。

In conclusion, these results suggested that (1) the ageing-associated decline in fertility of female KM mouse was due to a decrease in both quantity and quality of oocytes;(2) the ooplasm from young mice did not correct the meiotic errors of aged mice, and the ooplasm from aged mice did not induce abnormal segregation of meiotic chromosome of young mice, indicating that meiotic anomalies found in the oocytes of aged mice might be related to nucleus or chromosomes and relevant factors;(3) a critical nucleocytoplasmic ratio was essential for normal maturation and segregation of meiotic chromosomes of oocytes and development to 2-cell embryos.
本研究结果表明:(1)昆明白小鼠与衰老相关的生育力下降是其卵母细胞数量减少和质量下降的综合结果;(2)年轻小鼠卵母细胞细胞质不能纠正老龄小鼠GV的减数分裂错误,老龄小鼠卵母细胞细胞质也不诱导年轻小鼠的GV发生减数分裂错误,老龄小鼠卵母细胞减数分裂异常很可能与细胞核或染色体及其相关因素有关;(3)关键的核质比对卵母细胞正常的成熟、减数分裂染色体分离及2-细胞期胚的发育是绝对必需的。

Under the transmission election microscope, we had observed that the state of oocytes arid the cumulus cells around them was tightness, and there were plenty of long and thin microvilli playing the role of connection in the enwrapping. The shape of cumulus cells nucleus was ovate, and the longer and shorter diameters of the cumulus cells were 4.250±0.042μm and 2.750±0.07 μm respectively. The zona pellucida was well proportioned and tightly linking with oocyte. There were great deals of multi-crista mitochondria, lipid droplet and vacuolus. The mitochondria longer and shorter diameters were 0.600±0.106μm and 0.490±0.117μm. Granular nucleoplasma distributed very well in the cell nucleus.
电镜下,卵母细胞外的卵丘细胞紧紧包裹卵母细胞,且与卵母细胞之间有大量细长的微绒毛相联系;卵丘细胞核呈卵圆形,其长径为4250±0.042μm,短径为2.750±0.071μm;透明带均匀,与卵母细胞结合紧密;在皮质区集中分布大量的多峰型线粗体、脂滴和空泡,线拉体长径为0.600±0.106μm,短径为0.490±0.117μm;细胞核中颗粒状的核质分布非常均匀。

The results were as follows: nanos 1 mRNA uniformly dispersed throughout the cytoplasm of oocytes at all stages. Strong expression of nanos1 mRNA was observed in oogonia and stageⅠ、Ⅱ oocytes, but the signal became weaker in later stage oocytes.
结果表明:在斑马鱼卵子发生中,nanos1 mRNA均匀分布于卵原细胞和各时期卵母细胞的胞质中;在卵原细胞和Ⅰ、Ⅱ期卵母细胞中,nanos1 mRNA的杂交信号十分强烈,而较晚期卵母细胞中信号明显减弱。

Most sperm nuclei eventually developed into the male pronuclei, just like the normal sperms, except sperm nuclei in a few zygotes kept dense throughout the fertilization process. Dense chromosome body was seen at the nuclear area during the prophase of first mitosis, and in the middle of spindle at metaphase of first mitosis.
精子入卵后形成精核,大多能够逐渐解凝、液化并膨大,最终形成形态正常的雄性原核,但在第一次卵裂早期退化成浓缩的染色质小体,并在胞质分裂时随机地分配到其中一个子细胞里的分裂沟附近。
