In conclusions: 1 The treatment that buffalo occytes are cultured in Ionomycin (5 min)+CDM (3 h)+ 6-DMAP(3 h) after ICSI with sorted sperm can improve their subsequent embryonic development; 2 The dead ultrasoniced sorted sperm can be used for ICSI; 3 The result of ICSI with sorted sperm is similar to that with unsexed sperm, but the result of IVF with sorted sperm is lower than that with unsorted sperm; 4 The treatment of heparin after ICSI with sorted sperm can improve the blastocyst development rate; 5 The development rate of blastocyst with sorted sperm was variable among buffalos indicating that sorting high quality sperm from specific buffalos can increasethe efficiency of ICSI.

结果表明：1水牛分离精子ICSI后用Ionomycin(5min)+CDM(3h)+6-DMAP(3h)方法激活处理能提高其胚胎发育率；2分离后的死精子经超声断尾也能用于水牛卵母细胞的ICSI；3分离精子的ICSI效果不低于未分离精子，但分离精子的IVF效果却低于未分离精子；4肝素能促进分离精子ICSI后的胚胎发育；5分离精子ICSI后的胚胎发育率在不同公牛之间有差异，选择能产生高质量精子的公牛进行精子分离，可以提高ICSI的效率。

The variation to vitellin polypeptide was studied by SDS-PAGE during embryogenic and postembryonic development to Chrysopa septempunctata. The results indicated that vitellin was degradated constantly during embryonic development, and the bands of vitellin couldn't be detected in the 4th day of ovum development.

BFGF immunoreaction was detected at 3-weeks' embryonic neuroepithelium, and remained positive throughout various development a l stages examined, whereas NGF immunoreaction appeared after 4-weeks. The expres sion varied gradually with the development of embryos. There was no specific EGF immunoreaction in all tissues and stages examined. The occurrence and distribut ion of FGFR, NGFR and EGFR were similar, and their expression altered with the development.

As an "acceptor", the teachers" professional development will be influenced by many exterior factors, namely the restrictions and limitations, which includes the factors from the society and school which are expounded on from the outside to inside and one tier after another. As a "subject", the impellent of the teachers" subjectivity plays an essential role in their professional development by reasons of the intrinsic factors-teachers" activity, sociality, independence and creativity, that is the teachers" subjectivity in the professional development. As an "object", teachers have obvious characteristics and relatively centralized needs and attention in their development, so the teachers"development is quite different from other professional development in developing phases and training modes, viz, the uniqueness of the stages of the teachers" professional development. The factors analysis connotes two clues. One is the lognitudinal analysis from "acceptor" to "subject", the other is lateral analysis from the "object".

外在影响因素包括社会影响因素和学校影响因素两方面，采用由外向内，逐层递进的考察方式；第二个层面是把教师看作"主体"，教师在专业发展中不只是被动地接受外部的影响，教师本身具有能动性、社会性、自主性和创造性，教师要受到自身各种内在因素的影响，教师专业发展要考虑教师主体性的发挥对自身发展的推动，即"教师专业发展的主体性"；第三个层面是把教师看作"本体"，教师在专业发展中具有相对明显的阶段性特征和相对集中的教师发展需要与教师关注点，教师专业发展作为一种相对独立的专业发展历程，有区别于其他专业发展历程的独特的发展阶段特点和培养模式，即"教师专业发展的独特阶段性"。
