Effects of DHYZ on H₂O₂-mediated cytotoxicity. PC12 cells were treated with H₂O₂ for 4 h (a) or DHYZ for 24 h (b) and cell proliferation was detected by CCK-8 assay. PC12 cells were pre-treated with DHYZ for 24 h, followed by H₂O₂ treatment for 4 h and subjected to CCK-8 assay (c) and LDH release assay (d). ^△P < 0.01, versus normal group; ^*P < 0.05, ^**P < 0.01, ^***P < 0.001, versus control group. The data are mean ± SD of three independent experiment each in triplicate
