Flow cytometric analysis showing the effects of fermented Aloe juice on the TNF-α and IFN-γ production by LPS-induced PBMC cell model. Cells were incubated with or without LPS (1mg/mL) for 24 h, in the presence or absence of Aloe at the indicated concentration. a untreated PBMCs negative control for INF-γ, b LPS-induced PBMCs (Positive control for INF-γ), c Aloe-treated PBMCs for INF-γ, d untreated PBMCs negative control for TNF-α, e LPS-induced PBMCs (Positive control for TNF-α) and f Aloe-treated PBMCs for TNF-α. Data are presented in the graph as mean ± SE where statistical significance was tested using one-way ANOVA (*P < 0.05, ** P < 0.001)
