纤维结合蛋白(FN)是一种具有广泛生物学功能的糖蛋白,它能促进细胞与细胞、细胞与基质的粘连,调理单核巨噬系统的吞噬功能。近年来发现冷沉淀中富含FN,国外已用于纠正创伤、烧伤和严重感染患者血浆的低FN水平。1989年以来,我们对冷沉淀和冷沉淀FN滴眼剂的FN含量进行了检测,现报告如下。 Fibronectin (FN) is a glycoprotein with a wide range of biological functions. It promotes the adhesion of cells to cells, cells and matrix, and modulates the phagocytosis of mononuclear macrophage system. In recent years, it has been found that cryoprecipitate is rich in FN, and foreign countries have been used to correct low FN levels in plasma of patients with trauma, burns and severe infections. Since 1989, we have examined the FN content of cryoprecipitate and cryoprecipitate FN eye drops and are reported below.
