High doses of methamphetamine that cause disruption of the blood-brain barrier in limbic regions produce extensive neuronal degeneration in mouse hippocampus.

Abstract

Histological examination of brain after a single high (40 mg/kg) dose of D-methamphetamine (METH) was used to determine the relationships between blood-brain barrier (BBB) disruption, hyperthermia, intense seizure activity, and extensive degeneration that this exposure often produces. In very hyperthermic mice (body temperatures > 40.5 degrees C) exhibiting… (More)
