Figure 5: Effect of rikkunshito on plasma ghrelin levels in mice exposed to novelty stress. Plasma ghrelin levels were determined 3 h after onset of novelty stress. (a) Plasma acylated ghrelin level. (b) Plasma des-acyl ghrelin level. Data are expressed as the mean ± SEM of 8 mice. *** versus control group by Aspin-Welch’s -test and ## versus the distilled-water-treated mice exposed to stress by Dunnett’s analysis. DW: distilled water. The partial data of acylated ghrelin level indicated in this figure are derived from .
