There is disclosed a cross-linked hyaluronate compound obtained by reacting a sodium hyaluronate compound with a polfunctional aziridine compound as a cross-linking agent. The polyfunctional aziridine compound was added to hyaluronan of various molecular weights in an equivalent ratio of HA/AZ of 1:1 to 1:10, preferably, 1:3 to 1:10, more preferably, 1:3 to 1:5; most preferably 1:4 to 1:5. The polymeric hydrogel compounds obtained are useful to prevent the formation of post-operative adhesions, designing tissue engineering applications, and the like.
披露了一种交联透明质酸化合物,其通过将钠透明质酸化合物与多官能环氧乙烷化合物作为交联剂反应而获得。将多官能环氧乙烷化合物添加到不同分子量的透明质酸钠中,其HA/AZ的当量比为1:1至1:10,优选为1:3至1:10,更优选为1:3至1:5;最优选为1:4至1:5。所获得的聚合物水凝胶化合物可用于预防术后粘连的形成,设计组织工程应用等。
