Results: IL-8 protein was located in the epithelium of viii. The expression of IL-8 was significantly increased in RSA group than that in the control group. Positive IL-8 cells was shown in decidua of RSA group, and its IL-8 level was higher than that in the control group. By hematoxylin-eosin staining. trophoblastic layer was found to get thinner, cells of trophoblastic layer denatured or necrotized, and turned acidophily, and the fibration of villous axis increased in RSA; decidual cells lost connection, a part of decidual cells appeared cytoclasis and turned more acidophilic, and nuclei disappeared in RSA.

From the early study of the pathogenesis of pre-eclampsia people have found its association with immunological function . In 1986 Ellis et al[1] had found that the extravillous chorionic cytotrophoblast contacting with the maternal tissue expressed high levels of Human leukocyte antigen-G, a major histocompatibility tissue-specific antigen . Extravillous chorionic cytotrophoblast with high levels expression of HLA-G proteins can invade the maternal deciduas and the maternal spiral arteries by displacing the endothelial lining and destroying most of the musculoelastic tissue of these arteries .

早期研究开始，许多学者即发现其与免疫学有密切关系，至1986年Ellis等[1]发现人类白细胞抗原(human leukocyte antigen，HLA) G分子高度表达在绒毛外滋养层细胞( extravillous cytotrophoblast，EVCT)上，即浸润至子宫蜕膜层甚至达子宫浅肌层以及子宫螺旋动脉内皮层，与母血及子宫组织直接接触的滋养细胞，这种独特的组织分布提示HLA-G分子在母胎免疫耐受方面起重要作用。

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.

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.

chorion：绒毛膜

1.绒毛膜 绒毛膜(chorion)由滋养层和衬于其内面的胚外中胚层组成. 植入完成后,滋养层已分化为合体滋养层和细胞滋养层两层,继之细胞滋养层的细胞局部增殖,形成许多伸入合体滋养层内的隆起,这时,表面有许多突起的滋养层和内面的胚外中胚层合称为绒毛膜.

chorion laeve：平滑绒毛膜
