It is possible that mice and rats don't have a bbb, or don't have a very good one? For the purpose of keeping toxic metals out of the brain, the human would need this since they live over 50 years, but a rat which dies much sooner, would likely not accumulate enough metal in the brain during it's lifetime to make it need such an efficient one.
I would feel much more comfortable with studies done on primates or at least pigs than mice and rats. Marshall -- The silver-list is a moderated forum for discussion of colloidal silver.
