图 2 不同浓度的 H2O2和苏木素对细胞活力的影响Fig.2 Effects of different concentrations of H2O2and hematoxylin on cellviability.Cell viability was detected by MTS assay. Cytotoxic effects of H2O2(A) andbrazilin (B) on PC12 cells. The cells were treated with H2O2for 24 h or withbrazilin for 36 h with the indicated concentrations. All data are expressed asmeans ± SEM and represent three independent experiments. Bars withdifferent characters indicate statistical difference at P<0.05 level.
图 3 苏木素抑制 H2O2诱导的 PC12 细胞的细胞毒性Fig.3 Brazilin suppressed H2O2-induced cytotoxicity in PC12 cells. Morphological observation. Cells after treatment were observed se contrast microscope (×200). (B) Brazilin attenuated H2O2-inrease of cell survive. The PC12 cells were pre-treated with or wilin for 1 h and co-treated with H2O2for another 24 h. All daressed as means ± SD and represent three independent experiments different characters indicate statistical difference at P<0.05 level.
20图 4 苏木素对 H2O2诱发的 PC12 细胞凋亡、坏死的影响Fig.4 Effects of brazilin on H2O2-induced apoptosis and necrosis on PC12cells.(A) PC12 cells were exposed to 200 μM of H2O2and different concentrationsof brazilin for 24h. After the treatment, the staining cells with AnnexinV-FITC and PI-labeling were analyzed by flow cytometric. Apoptotic cells (B)and cell necrosis (C) were analyzed. Results are presented as means ± SEM(n=5). **P<0.01, compared with control group, *P<0.05, compared withH2O2-treated group.
