绒毛膜

Methods: By using immunohistochemical analysis EMMPRIN expressions in chorionic villi and deciduas were evaluated.

目的 探讨先兆流产时绒毛及蜕膜组织中细胞外基质金属蛋白酶诱导因子的表达情况。

Methods Expressions of TGF -β1 mRNA and its receptors were detemined in villi and deciduas by semi-quantitative reverse transcriptional-polymerase chain reaction from 38 cases of spontaneous abortion women and 35 cases of normal early pregnancy women.

应用半定量逆转录-聚合酶链反应技术，检测 38 例 RSA 患者和 35 例正常早孕妇女的绒毛及蜕膜组织中 TGF -β1 mRNA，TβRmRNA 的表达情况。

The mechanism of mifepristone for termination of early pregnancy might be related to the down-regu- lated expression of OPN and up-regulated expression of p53 protein in the chorion and deciduas.

米非司酮终止早孕的机制可能与绒毛及蜕膜的OPN表达下调，p53蛋白表达上调有关。

The basolateral M cell surface is invaginated to form an intracellular central pocket into and out of which lymphocytes and macrophages.

M细胞是一种特化的上皮细胞，多分布于Peyer's结圆顶区的周边，FAE的顶端未见M细胞；其结构有别于相邻的肠上皮细胞，表面没有长而整齐的微绒毛，取而代之的是粗而短的微皱褶，胞质内终末网不发达，溶酶体较少，基底膜向顶部穹隆状突起，形成一&口袋&样结构，其中含有多个免疫活性细胞。

In rat esophagus, the positive varicosities and fibres could be observed in the circular muscle layer and the muscularis mucosae layer at 21st day before birth. With the development of rat digestive tract, neurokinin A-immunoreactivity positive nerves could be observed gradually in the epithelium, submucosa, longitudinal muscle layer, myenteric plexus and submucosal plexes, while mature nerve fibres could be seen at one month after birth. 2. In rat stomach, the positive reaction of NKA initially happened in the myenteric plexus at the 14th day of embryo, and then appeared on circular muscles, longitudinal muscles, submucosal, muscularis mucosae, lamina propria and epithelium. 30 days after birth, expression of NKA is same as seen in adaulthood. 3. In rat small intestinal, the NKA-IR could first be found in the myenteric plexus of the duodenum, jejunum and ileum at 14th , 15th and 17th day before birth respectively. Then the NKA-IR occurred in the longitudinal muscle layer, circular muscle layer, intestinal villus, intestinal gland, muscularis mucosae, submucosa, submucosal plexes, mucosa plexus and deep muscular plexus.

结果 1、在食管，于胚胎21天的粘膜肌层和环肌层内观察到神经激肽A免疫阳性膨体纤维，出生后，随幼鼠的生长发育，相继在上皮，粘膜下层，纵肌层、肌间丛、粘膜下丛有NKA-IR表达，30天时已和成年鼠相似；2、在胃，首先于胚胎14天的肌间丛出现NKA-IR的表达，随发育相继在环肌、纵肌，粘膜下层、粘膜肌、固有膜及上皮内出现NKA-IR的表达，30天时具备成年鼠的分布特征；3、在小肠，分别于胚胎14、15、17天的十二指肠、空肠和回肠的肌间丛处出现NKA-IR的表达，随发育相继出现在纵肌、环肌、绒毛、小肠腺周、粘膜肌、粘膜下层、粘膜下丛、粘膜丛、深肌丛。

The injured gill cells had a different ultrastructure, with endoplasmic reticulum dilated and vesiculated, mitochondrial cristaes partially disintegrated, gill fibre cuticles denatured and dropped. The ultrastructural damages to hepatopancreatic cells were characterized by the decrease of microvilli, swelling and breaking up of mitochondria, expansion of endoplasmic reticulum, disruption and vacuolization of nucleus, tumefaction of nuclear membrane and increase of lipid droplets. As for the toxicological changes of myocardial cells, the mitochondria were swelling, having a lot of vacuolus and disintegrating, while the myofibrils were irregular with endoplasmic reticulum dissolved.

鳃细胞的损害表现为鳃丝水肿，细胞器溶解，角质层变薄，线粒体、内质网的肿胀、解体；肝胰脏细胞的主要损害特征为肝管微绒毛减少，线粒体水肿解体，内质网扩张，细胞核空泡化，核膜水肿和脂肪滴增加；心脏细胞的毒理变化为线粒体内嵴肿胀、瓦解，肌原纤维不规则，内质网溶解。

The villi in the synovial membrane were different in different joint.It was different in different part of the same joint.

关节滑膜和绒毛形态在不同的关节及同一关节的不同部位都不尽相同。

Methods The chemical hypoxia was induced by incubation of U251 cells with cobalt chloride.

以氯化钴模拟缺氧，采用RT-PCR、免疫细胞化学方法分别检测缺氧诱导因子-1α和血管内皮生长因子mRNA和蛋白的表达，鸡胚绒毛尿囊膜模型检测缺氧时胶质瘤细胞血管生成情况。
