case1102

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 possess a similar barrier) to study a method of disrupting the
 barrier by infusing a solution of concentrated sugars.
