METHODS On the basis of the animal model of traumatic DBI caused by free dropping,we measured the water content,the levels of TXB2,6-keto-PGF1α,cAMP and cGMP,and observed the changes of the blood-brain barrier permissibility by the Lanthanum Nitrate labeled electroscope to assess the protective effect of MCPG on the brain tissues after DBI in rats.

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。

Results: MC of tryptase immunoreactivity contain abundant F-actin ring that region of cytomembrane endothecium form a barrier of blocking tryptase liberation. Copious tryptase temporarily was stored in secretory vacuole, and small amounts tryptase was released from secretory vacuole for depolymerize of F-actin ring in cell.

结果：类胰蛋白酶免疫反应性的肥大细胞内含有丰富的丝状肌动蛋白环，在质膜内层区域形成阻碍类胰蛋白酶释放的屏障；大量的类胰蛋白酶暂存于分泌泡中，少量的类胰蛋白酶因细胞内丝状肌动蛋白环的解聚使之从分泌泡中释放。
