Fig. 4From: Germacrone protects against oxygen-glucose deprivation/reperfusion injury by inhibiting autophagy processes in PC12 cellsEffect of different concentrations of germacrone on PC12 cell viability a Detection of the effect of 1.25–80 μM germacrone on PC12 cells viability by MTT assay. b Detection of the effect of germacrone on PC12 cells viability after OGD/R injury by MTT assay. Note: n = 6; ##P < 0.01, vs control group; *P < 0.05, **P < 0.01, vs OGD/R groupBack to article page
