| Outline of Final Research Achievements |
A clinical and basic study was conducted aiming at one-day photodynamic therapy. As a clinical study, clinical trials using Talaporfin sodium- PDT were continued. Talaporfin sodium- PDT was performed on 9 CIN cases, and cure was confirmed in 8 cases that could be followed up. In the basic study, the effect of PDT was examined by administering a smaller amount of Talaporfin sodium than usual in mice, and the enhancement of the antitumor effect of ulinastatin, betamesazone valerate, and indomethacin was confirmed.

| Academic Significance and Societal Importance of the Research Achievements |
今回臨床的検討で確認できたレザフィリンPDTの治療効果は優れていたため、早産を伴わないCIN治療として臨床へ応用できる可能性が示唆された。基礎的検討で得られた、ウリナスタチン、ベタメサゾン吉草酸エステル、インドメタシンの増強効果は投与タイミングで効果が変化するため、今後臨床試験を行うことでより副作用の少ない治療が期待できると考える。
