The current presence of sodium ions markedly decreased the binding of 8-OH-DPAT however, not the binding of “type”:”entrez-protein”,”attrs”:S14506″S14506 [11]. “type”:”entrez-protein”,”attrs”:”text”:”S14506″,”term_id”:”110239″,”term_text”:”pirS14506 potently reduced the duration of immobility in the forced swim test in rats at the minimal effective dose (MED) 0.01 mg/kg, s.c.
