Cell viability detected by MTT assay. (a) Ox-LDL-induced cell injury in HAECs. (b) The protective effect of EOFAZ on cell viability. HAECs pretreated with EOFAZ (1, 2, or 4 μg/mL) for 2 h prior to treatment with ox-LDL for 24 h. This treatment is used in the following experiments. The survival rates are shown by the mean ± S.E.M of three experiments: , compared with control group; , compared with ox-LDL group.
