紧密连接的

Objective: To study the expressions of Cx26, Cx30 and ZO-1 and relationship in the cochlear sensory epithelium.

目的：研究耳蜗基底膜组织中Cx26、Cx30和紧密连接ZO1的表达和相互关系。

ZO1 and Cx26 expressions in the sensory epithelium have different location and were not overlapped. Tight junctions maintain the ion barrier between the endolymph and perilymph,and gap junctions take part in ion transportation.

Cx26和Cx30分布在基底膜的各种支持细胞，在感觉毛细胞没有表达；此外，该研究发现Cx26和ZO1在耳蜗内具有不同的表达方式和表达部位，紧密连接ZO1在网状板面构成了毛细胞之间或与其支持细胞之间的离子屏障，阻止内、外淋巴之间的相互流通，保持了各自之间的离子平衡；缝隙连接则表达在基底膜的深层，参与离子转运。

HA increased level of NO by activating NOS after combining with H〓 and H〓 receptors; and on the one hand 5-HT caused brain microvessel endothelial cells constracting strongly, made the tight joint opening, increased the permeability of BBB, and on the other hand 5-HT increased the quantity of pinocytosis vesicle in endothelial cells and enhance the permeability of BBB after comining with 5-HT〓 receptor.

HA与H〓和H〓受体结合，激活NO合成酶，使NO含量增多而诱发BBB通透性增加；5-HT与5-HT〓受体结合，一方面引起脑微血管内皮细胞强烈收缩，使内皮细胞间的紧密连接开放，BBB通透性增高，另一方面可引起内皮细胞转运小泡增加，BBB通透性增高。

METHODS: Healthy, pigmented, adult guinea pigs of both sexes with intact Preyer's reflex were divided into 3 groups (cochlea group,brain group and lung group).

成年健康杂色豚鼠，耳廓反射灵敏，分别取耳蜗、脑、肺三组组织，免疫组织化学法及Western Blot研究紧密连接蛋白occludin，ZO-1在耳蜗外侧壁血管纹中的表达，以脑组、肺组为阳性对照。

AIM: To investigate the expressions of occludin and ZO-1 in the lateral wall stria vascularis of the guinea pig cochlea.

目的：研究紧密连接蛋白occludin，ZO-1在豚鼠耳蜗外侧壁血管纹中的表达。

Tight junctions are essential intercellular junctions, because their barrier and fence functions are indispensable for the establishment of compositionally distinct compartments in multicellular organisms.

紧密连接是上皮细胞间一个重要的连接构造，其功能对建立多细胞生物的隔室扮演不可或缺的角色。

The male's swimbladders increased faster than weight the than females. Morphology of the sciaenids can be grouped to two types. Type I including red drum: the ratio of sonic muscle and body weights is smaller, and the sonic muscles are tightly connected to the swimbladder. Type II including Pennahia argentata, Johnius tingi, Atrobucca nibe, Larimichthys polyactis, and Pennahia macrocephalus: the ratio of sonic muscle and body weights is larger, and the sonic muscles are loosely connected to the swimbladder by membrane tissue.

比较红鼓鱼和其他不同种类的石首鱼发声肌肉形态，发现可以分成二种：类型I即红鼓鱼，其发声肌肉重量较小，与泳鳔紧密连接；类型II即白姑鱼，丁氏叫姑鱼，黑，小黄鱼，大头白姑鱼的发声肌肉重量较大以膜状结缔组织连接而易於剥离。

But in day 14th and day 28th groups, the ratio of macrophagus positive area in lung interstitium was bigger than that of control group（ P 〈0.05 ）, with collagen fibers depositing in the lung interstitium gradually.

结论博莱霉素鼠肺毛细血管内皮细胞间紧密连接持续开放，与巨噬细胞在组织间浸润密切相关，并可能是博莱霉素致肺纤维化发生的重要因素。

These critical spermatozoal functions are acquired in the epididymis where a specific luminal environment is created by the blood-epididymal barrier; proteins secreted by epididymal principal cells bind to maturing spermatozoa and regulate the maturational process of the spermatozoa.

精子功能在附睾特殊的管腔环境中获得，这一环境是由血-附睾屏障来维护。附睾主细胞分泌的蛋白与精子结合并调控精子的成熟。附睾中细胞-细胞间的相互作用通过粘附连接和紧密连接形成。

With the rapid development of modern industry and technology, the requirement of the sealing performances of bolted flanged connections is more and more rigorous.

现代工业和科学技术的迅速发展对连接系统的密封性能提出了越来越高的要求，提高高温连接的紧密性已成为当前过程工业中亟待解决的课题。

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。
