In this article, collagen protein was extracted from bovine tendon by enzyme digestion and was spread to form membrane materials. Then the materials were crosslinked by formaldehyde to form guided tissue regeneration materials. The results from the test of physical and chemical properties of materials show that the mechanical properties and water absorption ability of materials exceed those of foreign products. Also the major structrual groups like carbonyl, carboxy, hydroxy and amino groups still exist. According...

In this article, collagen protein was extracted from bovine tendon by enzyme digestion and was spread to form membrane materials. Then the materials were crosslinked by formaldehyde to form guided tissue regeneration materials. The results from the test of physical and chemical properties of materials show that the mechanical properties and water absorption ability of materials exceed those of foreign products. Also the major structrual groups like carbonyl, carboxy, hydroxy and amino groups still exist. According to the observations of collagen enzyme in vitro and muscle implantation in vivo tests, the degradation times of the materials in vitro and in vivo are 240 hours and 60 days respectively and the degradation residue is hydroxyproline. The results of biological evaluations show good biocompatibility and no anaphylaxis,pyrogen and carcinogenicity. Therefore, it is concluded that as a kind of guided tissue regeneration material it is suitable for clinical use in guided tissue regeneration of oral diseases and also many other diseases.Correspondent: ZHANG Qiqing, Professor, Institute of Biomedical Engineering.Chinese Academy of Medical Sciences,P.O.Box 25(204), Tianjin 300192

用酶消化法从牛腱中提取出胶原蛋白,采用涂复法制成胶原膜材料,将该膜用0.25%的甲醛交联后得到用于牙周组织引导再生的材料.在对胶原材料进行物理、化学性能测试后表明:该材料的力学性能超过国外同类制品并具有较好的吸水性,而且胶原材料的羰基、羧基、羟基和胺基等主要结构基团依然存在经体外胶原酶和体内肌肉包埋降解吸收观察,材料在体外约240小时降解完全,降解产物为羟脯氨酸,体内吸收时间为60天左右.对该材料进行生物学评价后证明:该材料无三致反应和其它毒副作用,无热原和过敏反应及溶血现象等,生物相容性优良.因此,该材料可用于牙周组织引导再生术及更广泛的生物隔膜技术中.

本文用微量显微注射法,在金鱼视网膜的背侧用亲脂类荧光染料DiI标记少量神经节细胞,通过顺行标记研究了视神经再生过程中视网膜顶盖投射的精确化过程。在损伤视神经后的不同时期观察了再生视神经纤维在顶盖整装片上的分布。在再生早期它们以超出正常的途径由背腹两侧进入顶盖,广泛分布。但其中大部分仍分布于顶盖腹侧的靶区。在再生晚期通过精确化,重建如正常鱼一样精确的视网膜顶盖投射。这个精确化过程表现在以下三方面:(1)再生于顶盖错误区域的再生视神经纤维的消失;(2)再生早期视神经纤维主干上生长的侧部分支的消失;(3)到达靶区的再生视神经纤维形成重迭的终末分支。由以上结果推测,顶盖中可能存在两类不同的因子:一类是普通诱向因子,存在于整个顶盖中,它在再生早期引导再生的视神经纤维长入顶盖。另一类是神经营养因子,它具区域特异性,在再生晚期引导视神经纤维到达顶盖靶区,形成精确的视网膜顶盖投射。
