Figure 5From: Evidence-based antioxidant activity of the essential oil from Fructus A. zerumbet on cultured human umbilical vein endothelial cells’ injury induced by ox-LDL Effects of EOFAZ on SOD activity in HUVECs exposed to ox-LDL . HUVECs treatment and cell lysate preparation were performed as described in Figure 3. SOD activity was measured by the xanthine/xanthime oxidase mediated ferricytochrome c reduction assay. The values shown are mean ± S.E.M. of three experiments (four or five cultures per experiment). ## p < 0.01, vs. control group; **p < 0.01, vs. ox-LDL group.Back to article page
