title: Proof of plasmatic imbibition in rat musculocutaneous grafts: enzymatic proof using peroxidase.
abstract: At present, the concept of plasmatic imbibition is generally accepted. That is, observation of weight change or pigmentation methods of the grafts were established to support it. In the present study, we investigated plasmatic imbibition in rat musculocutaneous grafts histologically using peroxidase, which is one of the reductases. Tissue pigmentation by peroxidase became an insoluble sediment that indicated the sites of peroxidase activity. The entire contact surface of the graft with the recipient bed was stained brown within a few minutes after the operation. At 30 minutes, the panniculus carnosus and dermis were stained dark brown diffusely, extending toward the epidermis. This condition continued until the sixth day at least. As a result, peroxidase that was dissolved with the exudate between the graft and recipient bed was imbibed into the musculocutaneous graft.
