Protective effects of HAS on the cell viability of H₂O₂-stimulated PC12 cells. (a) The represented cell morphology of PC12 cells with different treatment (×100). (b) Effects of HAS on cell viability of normal PC12 cell. (c) Effects of HAS on cell viability of H₂O₂-induced PC12 cells under different concentration and time. (d) Effects of HAS pretreatment for 2 hours on cell viability of H₂O₂-induced PC12 cells. HAS: hydroxy-α-sanshool; Norm.: normal. The values were represented as the mean ± SD (n = 3). ^∗∗P < 0.01 vs. the control group.
