Outline of Final Research Achievements

Wound healing is hastened by the wound dressing of wet type. But this type cannot be applied to suppurative wound. Although a wound dressing containing antimicrobial agent is developed, wound healing is delayed because of its cytotoxicity. We found an inhibitor, which depresses toxin production by pathogenic bacteria without bactericidal activity. This compound does not exhibit cytotoxicity. Therefore, the wound dressing contained this inhibitor was prepared by soaking in 3 mM solution of the inhibitor and air drying. This dressing was plastered to the suppurative wound of immunodeficient hairless mouse, and its healing effect was examined. As the result, after 3 days from plaster, healing of suppurative wound was notably improved. Then both of enhancement of wound healing and depression of infection are achieved.
