On the morphological differentiation,by inducing of fetal calf serum,it wasshown that the cytotrophoblast cells underwent aggregation first,and the adjacentcytoplasm membranes became tightly contacted through desomosomes andcytoskeleton.Then the adjacent cytoplasm membranes disintegrated fragmentallyto form fusion pore-like structure.Finally the multinuclear cells formed and inwhich the intercellular desmosomes disappeared.Immunocytochemical stainingfurther demonstrated that the formation of syncytium was through cell membranefusion rather than the amitosis process.

细胞形态分化的研究结果表明：早孕胎盘来源的细胞滋养层细胞在血清诱导下，首先发生聚集，并通过桥粒和细胞骨架使相邻的细胞膜紧密接触；之后细胞膜发生片段断裂，形成融合孔样结构；细胞间桥粒消失，最终形成多核的合体细胞；免疫细胞化学分析进一步证实合体化是通过细胞膜融合而非无丝分裂（amitosis即细胞核分裂而细胞质不分裂）实现的。

Sertoli cells can provide a material basis and a favorable microenvironment for sperm. After X radiation, spermatogenic cells and mitochondrion dramatically swelling and lysis with a decrease of mitochondrial cristae, with the prolonging of time, the mitochondria damage get even worse, mitochondrial crista is disappeared.

Sertoli细胞在精子发生过程中可为精子发生提供物质基础和能力，为精子发生提供有利的微环境，对精子的生成有复杂的作用。X射线照射后即出现生精细胞和支持细胞线粒体明显肿胀，线粒体嵴减少，且随着时间延长，线粒体形态的损害进一步加重，线粒体数量减少，线粒体嵴消失。

Hepatic sinusoid capillarization plays an important role in occurrence of portal hypertension. The fenestra of endothelial cells in hepatic sinusoid reduces and the diameter of fenestra decreases. The formation of basement membrane impaires the substance exchange between blood and hepatic cells,which results in oxygen deficiency, metabolic product accumulation and cell necrosis.

肝窦毛细血管化在硫代乙酰胺诱导的肝硬化门脉高压发生中起重要作用，肝窦内皮细胞窗孔减少并减小，内皮细胞下基底膜形成使肝细胞与外界物质交换减少，导致细胞缺氧、代谢产物聚集，肝细胞坏死，最终导致门脉高压的发生。

Morphological and flourescent changes were assessed using confocal microscopy in whole-mount organ of Corti preparations. Results (1) After the animals were exposed to broadband noise at 122 dB SPL in 4 h/day for 2 days, both apoptosis and necrosis appeared in OHCs. The single strand DNA in apoptotic OHCs were observed both in guinea pigs and mice.(2) In normal OHCs, EndoG was distributed outside of nuclei. EndoG translocated from outside to inside of the nuclei in both apoptotic and necrotic OHCs following noise exposure.(3) The MNNG cochlear perfusion and noise exposure both caused the transloctation of AIF from the mitochondria to the nuclei. The translocation of AIF took place in both apoptotic and necrotic OHCs.

结果 (1)暴露于120 dB SPL的白噪声环境中每天4小时，连续2天后引起豚鼠和小鼠耳蜗外毛细胞凋亡时，其细胞核内产生ssDNA，而在正常细胞内没有三ssDNA；（2）在正常情况下，EndoG分布于耳蜗毛细胞的细胞核外，在暴露于上述噪声后发生凋亡和坏死的豚鼠耳蜗外毛细胞中，EndoG从细胞核外转移到细胞核内，细胞核中的EndoG显著增加；（3）豚鼠耳蜗外淋巴灌流烷化剂MNNG后发生耳蜗外毛细胞凋亡和坏死，在凋亡和坏死的耳蜗外毛细胞中，AIF自线粒体转移到细胞核，其变化与噪声损伤引起耳蜗外毛细胞凋亡和坏死时一致。

According to the size and shape of oocyte, the morphology of nucleolus, the growth of yolk and the structure of follicle, oogenesis of H. d. supertexta can be divided into three stages as follows: oogonium, previtellogenic oocyte and vitellogenic oocyte. The ovary wall is composed of tunica adventitia and germinal epithelium which will produce oogonia and follicle cells. The follicle is the structure unit of ovary.

根据卵细胞的大小、形状，核仁的形态，卵黄颗粒的积累情况，滤泡的结构等，将九孔鲍卵子的发生分为卵原细胞、卵黄发生前的卵母细胞和卵黄发生期的卵母细胞3个时期；卵巢壁由外膜及内生殖上皮构成，生殖上皮分化产生卵原细胞和滤泡细胞；卵巢的结构单位是滤泡。

Leucocytic differentiation antigen 40 sign-al access participates in regulation of inflammatory reaction accommodation of major cell component (vascular endothelial cell、vascular smooth muscle cell and macrophage), it is playing critical role in AS process, participates ather-osclerotic occurrence and development ,reside in atherosclerotic plaque cell thro-ugh CD40-CD40L interaction, induce activate by itself , express and secrete profit to happen immune response、inflammatory reaction、hemagglutination t-hrombogenic proteo-cytokine.

白细胞分化抗原40 (CD40)信号通路参与了动脉粥样硬化斑块内主要细胞成分(血管内皮细胞、血管平滑肌细胞以及巨噬细胞)炎症反应的调节，其在AS进程中扮演着关键性的角色，参与了动脉粥样硬化的发生和发展；存在于AS斑块内的细胞通过CD40-CD40L相互作用，导致自身活化，表达和分泌了有利于免疫应答发生、炎症反应、血凝和血栓形成的蛋白质细胞因子，如激活在AS斑块中的关键性细胞成分如黏附分子、炎症因子、基质金属蛋白酶等的产生，导致斑块的不稳定和破裂，而最终导致粥样硬化斑块病变的恶化。

The pattern of aerenchyma formation could originate by the combination of cortical cell autolysis and enlarged intercellular space. The process occurred in some stages: cortical cells stopped expansion and the intercellular space became larger at the initial stage. Cortical cells to collapse and autolysis were found with the disintegration of cell contents. After the evacuation of cell contents, cortical cells became shrinking and invaginated.

形成过程大体分为：皮层细胞生长停止，细胞间隙增大；皮层细胞衰老，并发生自溶，内含物解体；解体物逐渐撤走，皮层细胞开始收缩、内陷，当细胞内含物全部撤走，相邻细胞的残留细胞壁叠合即在两侧形成通气空腔；径向上相邻的皮层细胞逐步发生凹陷和细胞壁叠合，结合方形的细胞间隙一起构成通气组织。

Piglet coccidiosis is a parasitic protozoosis, causing serious diarrhea. Thedisease mainly results from Isospora suis parasitizing small intestine epithelial cell ofnursing and freshly weaned piglets. Its main pathogen is I. suis, and the infected pigletsat 1 or 2 weeks postnatal exhibit nonhemorragic yellow or white diarrhea, with a lowmortality, but often followed by a consecutive bacterial or viral diseases, which increasesmortality in piglets and causes great economic losses in pig farms.

哺乳仔猪球虫病是由猪等孢球虫和某些艾美耳属球虫寄生于哺乳期及断奶仔猪小肠上皮细胞引起的一种以腹泻为主要临床症状的寄生性原虫病，其主要病原是猪等孢球虫，表现为出生后第一周发生非出血性的黄色至白色腹泻，临床症状并无特别之处，受害仔猪并不中止吮乳，死亡率较低，但常常会伴发一些继发性疾病(比如由细菌、病毒引起的疾病)，造成仔猪的死亡率升高，从而给许多猪场带来了较为严重的经济损失。
