β-Glucan extracted from strain I-6 demonstrated the attenuation of effects of water avoidance stress (WAS). (A) Effect of oral administration of β-glucan on the number of stool pellets in WAS-treated rats. (B) Effect of oral administration of β-glucan on the abdominal withdrawal reflex threshold in WAS-treated rats. The rats were divided into a sham WAS+vehicle group (n=8), a WAS+vehicle group (n=10), and a WAS+β-glucan group (n=8). Results are expressed as means±SDs. The sham WAS+vehicle group and the WAS+vehicle group are the same as those in Fig. 2. *p<0.01 compared with the sham WAS+vehicle group; ^†p<0.05, ^‡p<0.01 compared with the WAS+vehicle group.
