Figure 8.

Effect of α-asarone and/or lipopolysaccharide (LPS) on primary rat microglia cell viability as assessed by the MTT assay. Cells were preincubated with α-asarone (25, 50, and 100 µg/ml) and/or LPS (1 µg/ml) for 24 h. The results are shown as the percentages of the treated samples in relation to the control samples, x ± s. There was no significant difference in cell viability levels between the microglia in the serum-free Dulbecco’s modified Eagle’s medium-treated controls and the microglia treated with α-asarone (25, 50, and 100 µg/ml) and/or LPS (1 µg/ml).
