Figure 2: Effects of young green barley leaf extract on the serum corticosterone concentration in mice subjected to forced swimming Values represent the mean ± SEM for eight mice. **P < 0.01 versus the vehicle group (Dunnett's multiple comparisons). ##P < 0.01 versus Nil (Student's t test). Nil: non-swimming group; YGB400 and YGB1000: young green barley leaf extract at doses of 400 and 1000 mg / kg. Imipramine dose was 100 mg / kg.
