[Prolongation of rejection of porcine skin using iodine tincture].

Tincture of iodine compound with strong penetrating and broad spectrum disinfectant properties was used locally to prolong the rejection of porcine skin heterograft. We believed that injury of epidermis of porcine skin and infection may be the important factors for accelerating rejection phenomena after porcine skin grafting. The possible mechanisms for prolongation of rejection of porcine skin by tincture of iodine compound may by due to effective control of infection and coagulation of protein in epidermis whose antigenic property is very high, so the primary trigger factor inducing early skin necrosis is diminished.
