Effects of MPEE on the proliferation of H22, BEL-7404, HepG2 and NCTC1469 cells and splenocytes. A After MPEE treatment for 24 h and 48 h, the morphological changes of H22 cells were observed by inverted microscope. B–C The viability of H22 cells was measured by MTT assay after MPEE treatment for 24 and 48 h. D–F The viability of BEL-7404, HepG2 and NCTC1469 cells after MPEE treatment for 24 h. G The viability of splenocytes from C57BL/6 mice after MPEE treatment for 24 h. Data were analyzed by ANOVA. *p < 0.05; **p < 0.01; ***p < 0.001 compared to untreated group
