Abstract
Objective. Intraperitoneal adhesions are an important cause of postoperative intestinal obstruction, abdominal discomfort and infertility. In the present study we hypothesized that a combination of polypeptides with different surface properties, resulting in fine disperse low-soluble complexes, could be of benefit in the prevention of abdominal adhesions. Material and methods. Various polypeptides including lysozyme, polyglutamate, polylysine and combinations of all three were evaluated as compared to hyaluronic acid. A standard wound on the parietal peritoneum in mice was used and the evaluated agents were administered immediately postoperatively. The extent of peritoneal adhesions to the injured area was measured and expressed as a percentage of the wound length as evaluated after 7 days. Flow cytometry was performed to evaluate the effect on peritoneal macrophage survival and phagocytic function and the Pick test was used to determine peroxide production in order to estimate toxicity and potential impairment of macrophage function caused by the chemicals. Results. Significant differences were seen among the treatment groups ( p
