再组织

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。

Dissect the fascia from the dorsum down to the bursa oer the medial aspect of the metatarsal head. Then make a cured incision through the bursa and capsule of the joint Fig. 1-24,; begin the incision oer the dorsomedial aspect of the joint, continue it proximally dorsal to the metatarsal head and then plantarward and distalward around the joint, and end it distally on the medioplantar aspect of the metatarsophalangeal joint.

然后弧形切开滑囊及跖趾关节囊图1-24，，切口起自关节背内侧，自跖骨头背侧向近端延长，然后转向跖侧，再转向远瑞，环绕关节而行，最后在远端终止于跖趾关节的跖内侧面，此切口形成一椭圆形网球拍状组织瓣，连接于近节趾骨的基底部

Results (1) Primary callus came into being 3 days after operation. Mesenchymal cells from peripheral tissues around the primary callus were differentiated into chondrocytes 1 week later. Endochondral ossification was going on then. Bridging callus was formed in the fracture sites 4 weeks after operation.

结果 (1)伤后3 d开始形成原始骨痂。1周时肉芽组织中的间质细胞开始分化为软骨细胞，软骨形成后再进行软骨内化骨。4周时形成连接骨折端的桥接骨痂。

As for the animalmodel, we duplicated MCAO/reperfusion model on SD rats via reformed nylonmonofilament method and did obsevation and evaluation on early ethological andhistological changes, the constancy and reproducibility are satisfactory.

在模型方面我们采用了与临床病人发病情况相类似的SD大鼠MCAO局灶性脑缺血再灌注模型，运用早期行为学及组织学观察评价，通过改良线栓法成功复制了此模型，稳定性、重复性较好。

As the data are collected from this exegetical task, they are organized into the basic patterns of the individual books and then further of the individual authors.

由于收集的数据从这个训诂工作，组织他们到基本模式，个人书籍，然后再就个别作家。

Part 1: Permeability of Exogenetic BDNF through placental barrier of pregnant rats and blood-brain barrier of fetus with transient uteroplacental ischemiaObjective To investigate the potential of BDNF to penetrate the placental barrier and get into the fetus and pass through the blood-brain barrier of fetus to play neuroprotective function in the condition of transient ischemia.

第一部分：外源性脑源性神经营养因子在宫内缺氧环境中对胎盘及胚鼠血脑屏障通透性的实验研究目的：探讨外源性脑源性神经营养因子在宫内缺氧环境下能否通过胎盘屏障进入胎鼠体内，再通过胎鼠血脑屏障进入胎鼠脑组织而发挥其生物功能。

A large drop in hardness appears in as deformed samples at a temperature 45 ℃ lower than the start temperature of the exothermal peak after isochronal annealing, indicating that the recrystallization and grain growth process is closely relatine to annealing time and temperatur.

出现明显晶粒长大的温度较DSC曲线显示的放热峰起始温度低45℃左右，这主要是由于变形组织的回复再结晶过程是退火温度与时间的函数，降低处理温度并延长处理时间能达到与高温短时处理相同的效果。

RESULTS: As compared with group I-R, Fas/FasL mRNA slightly expressed in intima and extima of small pulmonary artery, alveoli, and bronchiole epithelia in group Pur. The values of AI, W/D and IQA showed significantly lower than that in group I-R at 60, 180, 300 minutes after reperfusion in lung tissue (P.01 and P.05). Meanwhile, abnormal changes of the lung tissue in morphologically were lessen markedly in group Pur.

结果：肺再灌注1h、3h、5h， Pur组Fas/FasL mRNA在肺小动脉内膜、肺小静脉内膜、肺泡上皮及肺支气管上皮呈弱阳性表达，明显低于同一时点I-R组(P.05)；AI、W/D和IQA值显著低于I-R组（P.01和P.05）；肺组织形态学异常改变不同程度减轻。

Add LHRH and LHRH-PE40 onto the section of cervical carcinoma tissue, then add rabbit anti-PE40 serum and fluorescin isothiocyanate-labeled goat anti-rabbit IgG and observe the fluorescence intensity under fluorescent microscope.

另取宫颈癌组织切片，分别加LHRH-PE40和LHRH后，再加兔抗PE40血清和羊抗兔IgG-异硫氰酸荧光素，在荧光显微镜下观察荧光强度。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
