目的 观察视网膜色素变性过程中，视网膜外节层内组织细胞肿瘤坏死因子α、神经组织蛋白S-100、细胞间黏附分子－1(ICAM-1)的表达情况，探讨其在视网膜色素变性过程中的作用及意义。

We discovered that the mechanisms of borneol opening BBB involved (1) promoting the tight junction of endothelial cells opening:(2) increasing the quantity of pinocytosis vesicle in endothelial cells and enhance the pinocytosis;(3) inhibiting the activation of P-glycoprotein (P-glycoprotein is an efflux pump of drugs) and increase the permeability of BBB;(4) reducing the expression of intercellular adhesion molecule-1 in brain microvessel endothelial cells;(5) increasing the concentration of Ca〓 in brain microvessel endothelial cells;(6) increasing the activation of eNOS in brain microvessel endothelial cells.

随后，在对冰片开放血脑屏障的机制作进一步的研究时又发现，冰片开放血脑屏障的机制包括以下几个方面：(1)冰片可使血脑屏障内皮细胞间的紧密连接开放；(2)冰片能使内皮细胞内的囊泡数量增加，吞饮功能增强；(3)冰片能抑制P-糖蛋白的活性（P-糖蛋白是一种药物外排泵），而使血脑屏障的通透性增加；(4)冰片能使脑微血管内皮细胞ICAM-1表达量减少；(5)冰片使脑微血管内皮细胞内的Ca〓浓度升高；(6)冰片可升高脑微血管内皮细胞eNOS的活性。
