Tissue localizing ability of protoporphyrin in mice have been described. Protoporphyrin was analized by means of Dresel' s method. The amount of protoporphyrin which localized in the transplanted tumor tissue of mice at various times following i v. injection (20mg/kg) was higher than in the skin, music or intestinal tissue but was less than in the liver or spleen tissue. These results show that tissue distribution of protoporphyrin was similar to that of Hp D. Furthermore, comparison of transmission between 514.5nm and 630nm light have been studied by PRT and spectrophotometer. The results suggested that 630nm light transmission was prior to that of 514.5nm light.
