球结膜和软脑膜微循环障碍相互关系的实验研究

本文报道应用高分子右旋醣酐形成家兔球结膜和软脑膜微循环障碍,并观察了它们之间的联系。在本组动物实验中家兔球结膜微循环障碍出现的时间比软脑膜微循环障碍出现的时间要早。在微循环障碍的程度上,球结膜较软脑膜为明显,但在红细胞聚集的变化上,则结果比较一致。因此本实验证实,在活体动物身上,球结膜微循环障碍在一定程度上可以反映脑微循环障碍的程度。

AN EXPERIMENT ON THE INTERRELATIONSHIP BETWEEN THE BULBAR CONJUNCTIVAL MICROCIRCULATION DISTUBANCE AND PSAl MICROCIRCULATION DISTURBANCE

The animal model of the bulbar conjunctival and pral microcirculation disturbance induced by high molecular weight dextran in rabbit were reported In this experiment.The interre'ationship between the bulbar conjunctival microcired ation disturbance and the pial miciocirculation disturbance, has been observed. We found that the occurrence of the buibar conjunctival microcirculation was earlier than the pial microcirculation. The degrees of abnormal bulbar conjunctival micro-circulation were more prominent. than that of the pial one, however, the degrees of erythrocyte aggregation in the bulbar conjunctiva Was similar to that of the cerebral microcirculation. The experiment showed the bulbar conjunctival microciculation disturbance, to some degree may reflect the degree of the cerebral microcirulation disturbance in living animals.
