Effects of KRG on plasma tryptophan (TRP), homovanillic acid (HVA), 5-hydroxyindoleacetic acid (5-HIAA), and the 5-HIAA/5-HT ratios in the hippocampus, and expression of tryptophan hydroxylase-1 (TPH-1) and tryptophan hydroxylase-2 (TPH-2) mRNA in the hippocampus of rats exposed to SPS for 14 consecutive days. PCR bands on agarose gels and relative intensities are shown. *p < 0.05, **p < 0.01 vs. SAL group; #p < 0.05, ##p < 0.01 vs. SPS group. SAL, saline-treated; SPS, single prolonged stress; KRG, Korean Red Ginseng; FLX, fluoxetine.
