Abstract: PURPOSE: Provided are an antiadhesion barrier preventive of the formation of adhesions attributable to surgical operation, infection, trauma, etc. and a method for preparing such an antiadhesion barrier. CONSTITUTION: The antiadhesion barrier is composed mainly of water-soluble and carboxymethyl cellulose with the alginate crosslinked by calcium ions. The barrier has a semi-interpenetrating network structure as a result of the crosslinking of the alginate with the calcium ions. In addition, to be superb in reattachment and bioreadhesiveness, the antiadhesion barrier shows high structural integrity maintenance and retains a certain degree or higher of strength even in a wet state. Also, it lacks blood anticoagulant effects, so that it can be applied for the surgical operations in which the surgical sites are relatively large or bleeding flows profusely. It can effectively prevent the formation of adhesion during injury healing. Further, the antiadhesion barrier is easy to handle and useful in surgical operations and secondary operative procedures.
