Fig. 4. Effect of probiotics GKLC1, GKM3, and GKS6 on the GSH (A) and CAT (B) activities in the liver of ethanol-fed C57BL/6 mice. Each value is represented as the mean ± SD (n = 6). Duncan's multiple range test was applied.

GSH, glutathione; CAT, catalase; GKLC1, Lactobacillus rhamnosus GKLC1; GKM3, Lactobacillus plantarum GKM3; GKS6, Lactobacillus paracasei GKS6.

^*P < 0.05, ^**P < 0.01, ^***P < 0.001 when compared to the positive control.
