Cyclosporine A Impairs Wound Healing in Rats
1983
Abstract Cellular immune responses may play an important role in the early inflammatory and cellular phases of wound healing. Cyclosporine A (CSA), a new immunosuppressive agent, impairs cellular immunity and T-cell-dependent humoral immunity. Therefore, the effect of CSA-induced immunosuppression in a rat wound-healing model was studied. Sprague-Dawley rats underwent a standardized skin incision and subcutaneous implantation of sterile polyvinyl alcohol sponges. CSA was dissolved in olive oil and given by gavage to one group of animals at a total dose of 125 mg/kg/10 days. The control group received an equivalent volume of olive oil. Ten-day-old wounds were weaker in CSA-treated animals, both in the fresh state (282 ± 19 g vs 380 ± 27 g, P P
