Figures & data

Figure 1. (a) The effect of cell viability sodium butyrate (NaB) in the BV-2 cells, (b) the effect NaB on cell viability in LPS-induced BV-2 cells, and (c) NO production against in LPS-induced BV-2 cells. Histograms were presented as mean ± SD, where n = 3. The p-value is determined by ANOVA with Tukey’s multiple test comparison and p-value less than 0.05 was expressed as statistically significant. *p < 0.05, **p < 0.001, and ***p < 0.0001 compared to the only TNF-α-treated group.
