Anti-adhesion gel containing polyhydroxyalkanoate

technical field [0001] The present invention relates to anti-adhesion gels comprising polyhydroxyalkanoates and hydrophilic organic solvents. The present invention also relates to the use of polyhydroxyalkanoate in the preparation of a medicament for preventing postoperative adhesions. Background technique [0002] The formation of tissue adhesions is a general response of the body to tissue trauma such as the peritoneum. Due to tissue trauma, connective tissue fiber bands are combined with adjacent tissues or organs to form abnormal structures. Tissue adhesion is a common pathological reaction (collectively called postoperative tissue adhesion in medicine), most of which occur after surgery (Menzies D, 1992; Dizerega GS, 1994; Holtz G, 1984; Ellis H, 1982). [0003] Adhesions formed between the wound and the omentum, most cases will involve the intestinal tract and other surrounding organs, causing serious complications such as intestinal obstruction, abdominal pain, femal...
