Inhibition of H22 cell growth with PPN treatment.

Notes: PPN was added to culture medium at different concentrations, and the cells were kept at 37°C for 24 hours. Next, a standard MTT assay was performed to measure the impact on the cellular metabolism of the H22 cells. The percent cellular metabolism is the normalization of OD₅₇₀ value to the control cells without treatment. Each data point represents the mean of three independent experiments. *Indicates P<0.05.

Abbreviations: MTT, 3-(4,5-dimethylthiazol-2yl)-2,5-diphenyl tetrazolium bromide; OD, optical density; PPN, Panax notoginseng.
