Outline of Final Research Achievements

Triamcinolone acetonide (TA), a steroid, is often used clinically to prevent dysfunctions associated with fibrosis. TA was suspended in biodegradable gelatin and freeze-dried in a sheet form. In this study, we prepared a TA suspension gelatin sheet (TA sheet) and confirmed both the homogeneity of suspended TA and controlled-release of TA in the presence of collagenase in vitro. The TA sheet decreased the rate of skin wound regeneration and caused less myofibroblast infiltration into the tissue than the control sheet did. In addition, the TA sheet caused less myofibroblast infiltration into the tissue than TA injection.

Academic Significance and Societal Importance of the Research Achievements

今回作製したトリアムシノロン内包化ゼラチンシートは、薬剤徐放性、線維化抑制効果を認めた。皮膚瘢痕拘縮、関節可動制限、消化管領域では食道狭窄など、線維化をきたす疾患に関しては、このシートによって改善が見込まれる可能性がある。シート自体はゼラチンを使用し、人体に無害であるため、臨床応用の可能性が示唆された。
