case1102: The Blood--Brain Barrier

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.
