Liver p65 mRNA expression and SOD level. (A): Liver p65 mRNA expression level. Compared with normal group (p < 0.05) *, compared with Alco group (p < 0.05) #. (B): Liver SOD level in mice. p65: Transcription factor p65, SOD: Superoxide dismutase. Normal: normal saline-fed; Alco: alcohol-fed group; A12-L: alcohol-fed with live B. animalis A12 cells group, A12-D: alcohol-fed with dead B. animalis A12 cells group, A12-P: alcohol-fed with B. animalis A12 freeze-dried power group, M18-6-L: alcohol-fed with live L. salivarius M18-6 cells group, and M18-6-D: alcohol-fed with dead L. salivarius M18-6 cells group.
