Abstract

In our previous studies, we found that behavioral sensitization evoked by repeated administration of methamphetamine (METH) was suppressed by the activation of the histaminergic neuron system in the brain. In continuation of these studies, we measured the levels of H1 and H2 receptor mRNAs in the rat striatum by semi-quantitative reverse transcription-polymerase chain reaction. Seven days after the 21 consecutive administrations of METH (4 mg/kg, i.p.), the levels of both H1 and H2 receptor mRNAs in the rat striatum increased significantly. However, 1 and 14 days after the last administration, there were no significant changes in levels of either H1 or H2 receptor mRNA in the rat striatum. These transient increases of H1 and H2 receptor mRNAs may have some relation to chronic METH abuse and its withdrawal. Copyright (C) 1999 Elsevier Science Ireland Ltd.
