Popis: This study explores the possible side effects on healing skin grafts of irradiation, commonly used intra-operatively following surgical tumor removal. The experimental model involved the delivery of a single 10-Gy dose of electron radiation to the recipient bed of a skin wound, followed by attachment of a full thickness rat skin autograft. Skin graft repair was assessed by light microscopy, immunohistochemistry, and transmission electron microscopy over a 3-week period for grafted and grafted-irradiated groups. Graft-bed irradiation reduced fibrinogen, fibrin, and fibronectin deposition in the wound. It also produced brief changes in the extent of both re-epithelialization and granulation tissue formation, and reduced the diameter of collagen fibrils in the granulation tissue. Despite these changes, the results suggest that graft-bed irradiation only delays the healing process, producing no serious clinical complications at the time points studied.
