Biodistribution of cationic porphyrins . Biodistribution of the porphyrins in various organs, after i.p. injection in C57/BL6 mice, bearing a subcutaneous melanoma tumour, at the concentration of 30 mg/Kg P2 and P4 and 9 mg/Kg C14 (the mice were not irradiatiated). Ordinate reports the percentage of injected dose (% ID). Distributions at 1, 3, 6, 9 and 24 h post injection are shown. Each bar is the average of 3 values (3 mice).
