Outline of Final Research Achievements

We administered 5-ALA intaperitonally a mouse peritoneal dissemination model, and emitted fluorescence of the tumor. We emitted tumor could detect the metastatic site. We tried photo dynamics therapy also. We found cell death by radiation wavelength 630nm with cultured cell. To irradiate whole peritoneum we injected fat emulsion into peritoneum, and light reflect diffusely and performed PDT. The growth suppression of cancer cell was seen by light radiation with the fat emulsion addition culture media. Treatment effect will improve if we regulate the size of the oil droplet of the fat emulsion and transducing plural LED light source with optical fiber in a peritoneal cavity.
