Figure 3: Effect of 7-Chloronorlichexanthone in combination with irradiation on the growth of murine SV40 transformed lymphoid sarcoma cells. The X axis is intensity (Gy) of radiation. The Y axis is cell count after 5 days of growth, normalized to cell count of the control. Cells were irradiated after treatment with 0.0001 μM 7-Chloronorlichexanthone. Confidence intervals at 95% are indicated. The difference between 0.5 Gy and control is significant (p=0.0012).
