Percentage of differential leukocyte counts after PDT and DOX treatments. Negative control (NC) received filtered water and no tumor implantation took place. In the control tumor (CT), tumor was implanted and no treatment was performed. Bar graphs were expressed as SEM (standard error of mean). Asterisks indicate highly significant differences (**p < 0.01) detected by the Bonferroni test, with a = significant compared to NC group. For groups’ nomenclature see Table 5.
