被诱导的心肌细胞的判定除常规指标外，我们还用了心脏特异性引物β-MHC对不同收缩时间的心肌细胞总RNA进行RT-PCR扩增和RNA斑点杂交，发现该心肌细胞不仅具有正常心肌细胞的特性，而且在分化早期就高度地表达心脏特异性基因。

The large stem and loop structure can be constructed from the sequence surrounding the 5' and 3' ends of the 16S rRNA gene.The stem is about h alf shorter than that of tobacco,due to a 79 bp deletion in Brassica napus chlor oplast.

5%、96.1%。油菜叶绿体16SrRNA基因5＇端上游及3＇端下游的顺序能互补而形成一个较大的茎环结构，但与烟草相比，由于3＇端下游顺序有79bp的缺失，因此，该结构中的茎部分大小仅为烟草的二分之一。

Epidermal cells near the wound dedifferentiate and proliferate forming blastema and/or migrate to the wound plane forming a pre-epidermis consisting of several layers of stem cells covering the wound plane, which then re-differentiates further forming fully developed epidermis. Cells in the parietal peritoneum are also induced by injury to dedifferentiate into stem cells which then proliferate and migrate along the parietal peritoneum to the wound place forming a pre-peritoneum which re-differentiates into fully developed parietal peritoneum.

伤口愈合包括伤口闭合、顶端表皮层及体腔上皮的新生：创伤后的前4 d，残腕顶端的肌肉组织向伤口处迁移并重排使伤口闭合；创伤附近的表皮层细胞发生脱分化并增殖后迁移到创伤面形成由数层干细胞组成的前表皮层，之后进一步分化形成表皮层；而体腔上皮细胞在创伤诱导下也脱分化并增殖，然后沿体腔上皮迁移到创伤处形成&前体腔上皮&，经再分化形成新的体腔上皮。

Flower buds ± cylindric; leaf blade broadly ovate basally on stem, usually triangular-lanceolate to linear distally on stem

Objective:to compare the effects between seed stem and commercial rhizoma gastrodia on memory dysmnesia induced by scopolamine in rat .methods: a month before the scopolamine administration, seed stem and commercial rhizoma gastrodia were given to two groups of young rats with scopolamine–induced dysmnesia model, incubation period of findingplatform were measured by means of morris watter-maze.

目的比较天麻种麻与天麻商品麻改善东莨菪碱诱发的记忆障碍的疗效。方法用天麻种麻，商品麻灌胃饲养幼鼠一个月，然后用东莨菪碱诱发大鼠造记忆获得性障碍模型，通过morris水迷宫测试大鼠寻找平台的潜伏期。

Result:seed stem and commercial rhizoma gastrodia (6g/kg) both can significantly improve dysmnesia on learning and memory ability in rat , even the effects ofcommercial rhizoma gastrodia reaches the normal level ;the seed stem reaches thehuperzinea.
