The Blood–Brain Barrier
血 - 脑屏障
译者:生物统计家园网 机器人LoveR
描述----------Description----------
The human brain is protected from bacteria and toxins, which course through the blood–stream, by a single layer of cells called the blood–brain barrier. These data come from an experiment (on rats, which process a similar barrier) to study a method of disrupting the barrier by infusing a solution of concentrated sugars.
人类的大脑免受细菌和毒素,当然通过的血液流,由单层单元称为血 - 脑屏障。这些数据来自一个实验(大鼠,处理类似的屏障),研究的方法破坏屏障注入浓糖的解决方案。
