Dextromethorphan is an NMDA receptor antagonist in the glutamatergic system. Currently, there are some reports showing that the glutamatergic NMDA receptor mechanism stimulates dopamine release from several brain regions. This effect may in part modulate the stereotyped behaviors of dopaminergic system. The purpose of the present study was to determine the interaction between the blockade of NM...

background: phytoestrogens, a group of plant-derived polyphenolic compounds have recently come into considerable attention due to the increasing information on their potential adverse effects in human health. some of phytoestrogens show estrogenic activity that may be carcinogenic for human. in the present study, we investigated the transcriptional effects of variety of phytoestrogens on the bo...

intraperitoneal (ip) injection of bupropion (3,6, amine (4,16 mg kg•&apos;) induced dose-dependent climbing in mice. the climbing response induced by both drugs were decreased in animals pretreated either with the 0-1 antagonist sch 233<)0 or the 0-2 antagonist sulpiride. the α-adrenoceptor blocker phenoxybenzamine decreased the climbing induced by both bupropion and amphetamine, but the β-adre...
