Analysis of mitochondrial DNA composition of the panda-rabit cloned embryos found that mitochondria from both panda somatic cells and rabbit ooplasm co-existed in early blastocyst, but mitochondria from rabbit ooplasm decreased and those from panda donor cells dominated in early fetuses after implantation.

结果显示，应用卵裂球电融合方法可以制作一系列的多倍体胚胎；小鼠囊胚的形成与胚胎中的细胞数目无直接关系，卵裂球的电融合和染色体数目的增加不会改变胚胎的发育进程；而胚胎细胞中的核／质比可能是控制胚胎囊胚化的一个重要因素。

MS medium equipmented with different kinds and concentrations of phytohormones were used to induce and subcultrue of calli from suaeda salsa L.

mg/ L上培养出盐地碱蓬的无菌苗，然后在 MS基本培养基中添加不同的激素种类及浓度配比，对所培养的无菌苗的下胚轴和叶进行愈伤组织的诱导与继代。

Toxicity tests showed dextran and trehalose solutions had no effects on in vitro development of morulae after exposed for 5-20 mm at 250C.

抗冻保护剂溶液对桑椹胚的毒性试验证明，25℃下，胚胎在葡聚糖和海藻糖溶液中平衡5-20分钟，对其体外发育无不良影响。

The histological observation showed that the larvae of S .japonicum in superinfected snails were sluggish in development, irregular, shrunken, deformed, relatively small in number as compared with the control. The sporocysts contained few germ balls or immature cercariae and most of the digestive glands of superinfected snails were atrophiej.

组织学观察发现各双重感染组钉螺消化腺萎缩，消化腺盲囊间隙只有少量血吸虫子胞蚴，血吸虫子胞蚴皱缩、变形及不规则，且子胞蚴中只含稀疏的尾蚴胚球，有的子胞蚴中已无胚球；而单独感染血吸虫的对照组中血吸虫均发育到成熟的子胞蚴或尾蚴。
