Effects of MEGR on the expression of METH-induced CPP in rats. In this study, rats were administered either METH or saline on alternating days for 6 days, and MEGR or DW was given 60 min prior to testing METH-induced CPP expression. METH treatment for 3 nonconsecutive days elicited CPP for the METH-paired chamber, which was blocked by pretreatment with MEGR. All data are expressed as means ± SEM (n = 7). MEGR: methanol extract of G. radix, DW: distilled water, S: saline, MEGR180: 180 mg/kg/day MEGR, SCH: a single SCH50911 (3 mg/kg) treatment,   ### P < 0.001 versus S/DW/S group; $$$ P < 0.001 versus S/DW/METH group (one-way ANOVA followed by Newman-Keuls post hoc test).
