The expression of cyclooxygenase-2 (COX-2) and striatal dopamine (DA) depletion in BALB/cAnNcrj (BALB/c) mice following a neurotoxic dose of methamphetamine (METH) was investigated. METH-treatment (4 mg/kgx4, 2 h intervals, s.c.) induced a significant hyperthermia and a persistent depletion of striatal DA levels 72 h after the treatment. COX-2, a marker of the cytotoxic effect of inflammation and oxidative stress and thiobarbituric acid (TBA) were significantly induced in the striatum 72 h after the METH-treatment, but not in the hippocampus. These results suggest that COX-2 may participate in METH-induced neurotoxicity in striatum. Copyright (C) 2000 Elsevier Science Ltd.
