Figure 5

Degradation of Pc 4 fluorescence due to photobleaching of Pc 4 in response to irradiation at (■) 50 mW/cm2 (n=5) or (●) 150 mW/cm2 (n=5), normalized to pre-PDT fluorescence. The increased rate of photobleaching at 150 mW/cm2 was found to be significant with a significance level of p<0.1. The points marked with an asterisk (*) are fluences for which the difference between fluence rates was significant with a significance level of p<0.05. Error bars are standard deviations of measurements made in n=5 tumors for each group.
