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.
A data frame with 34 observations on the following 9 variables.
Brain tumor count (per gm)
Liver count (per gm)
Sacrifice time (in hours)
Days post inoculation
Sex of the rat
Initial weight (in grams)
Weight loss (in grams)
Tumor weight (in 10^(-4) grams)
