以伊文氏蓝(Evan’s Blue)对脑组织的蓝染程度为判别指标,观察了家兔、大鼠灌服冰片后,伊文氏蓝对脑组织的着色。发现冰片能增强伊文氏蓝对脑纽织的蓝染程度,提示冰片有改善(提高)血脑屏障通透性的作用。
Evan’s Blue was used to determine the extent of blue staining of brain tissue. The coloration of brain tissue of Evan’s Blue was observed after irritation of rabbits and rats. It was found that borneol could enhance the blue dyeing of Evans blue to brain nasosin, suggesting that borneol could improve (enhance) the permeability of the blood-brain barrier.
