Figure 1

Proliferation of SP2/0 cells determined by MTT assay. (A) SP2/0 cells were treated with different concentrations of hypericin (0-10 μΜ) and irradiation doses (0–14.12 J/cm2) for 24 hours. (B) SP2/0 cells were treated with different concentrations of hypericin (0–0.1 μΜ) and irradiation dose of 11.28 J/cm2) for 24 hours. Results were shown as mean ± SD, n = 5, *p < 0.01.
