Adhesions in rat abdominal cavity were studied after laparotomy and subsequent single intraperitoneal injection of 2 ml of 5% aqueous solution of oxidized dextran (OD) with a molecular weight of 40 kDa (oxidation degree 10%). On days 7 and 21 after laparotomy, the number of adhesions in OD-treated rats was lower by 7.5 and 4 times than in animals not receiving OD. The number of neutrophils in adhesions on day 21 was manyfold lower in OD-treated rats. In 7 and 21 days after laparotomy, the number of fibroblasts in the adhesions of rats receiving and not receiving OD was similar, but 2-fold higher than in the peritoneum of non-operated rats. The content of collagen in adhesions on day 21 after laparotomy in OD-treated rats was 10-fold lower than in animals no receiving OD.
