Abstract The application of contemporary biochemical, analytical, and production technology have, in part, clarified the physiologic processes and identified many new factors active in wound repair. A restructuring of the sequence of the reparative events for the wound environment followed the identification of an array of hormonal polypeptides and growth factors. Deterrents of the early phases of repair include neoplasms and therapeutic doses of steroidal and cytotoxic agents. The physiological effects of these agents are rapidly reversed following their removal with a resultant enhancement of wound tear strength and wound energy. The use of synthetic growth hormone and recombinant DNA-produced polypeptide may reverse the deleterious wound healing events initiated in the injured and tumor-bearing host.
