    • A bio-artificial liver system is provided to prevent channeling and damage of gel beads by circulating plasma downward using height difference between a bioreactor and a plasma storing vessel and to allow removing toxicities in plasma and providing effective proteins more efficiently. A bio-artificial liver system comprises: a fixed layer bioreactor packed with gel beads(1) containing animal hepatocytes, which performs liver-like functions such as removing toxicities and providing effective proteins; a plasma separator(6) to separate plasma from blood, which is located in a place higher than that of the bioreactor and allows plasma circulation by height(pressure) difference; a plasma storing vessel(2); a flow speed controlling pump(5); inflow/outflow tubing(14,15) through which the plasma passes; and a linkage tube(4) connecting between the bioreactor and the plasma.
    • 提供生物人造肝系统以通过使生物反应器和血浆储存容器之间的高度差向下循环血浆以防止血浆中的毒性并且更有效地提供有效的蛋白质来防止凝胶珠的引流和损伤。 生物人造肝系统包括:装有含有动物肝细胞的凝胶珠(1)的固定层生物反应器,其执行肝样功能,例如去除毒性并提供有效的蛋白质; 血浆分离器(6),其将血液与血液分离,所述血液分离器位于比生物反应器高的位置,允许通过高度(压力)差异的血浆循环; 等离子体存储容器(2); 流量调节泵(5); 等离子体通过的流入/流出管道(14,15) 以及连接在生物反应器和等离子体之间的连接管(4)。

    • A porous collagen-hyaluronic acid composite material and a manufacturing method thereof are provided to minimize rejection in transplanting the composite material, to secure excellent mechanical property and tissue compatibility, and to make a manufacturing process simple. A porous collagen-hyaluronic acid composite material is produced by forming an aggregate by mixing collagen and hyaluronic acid at pH of 3.0~5.0 and then lyophilizing the aggregate. Atelo collagen or soluble collagen is used. The hyaluronic acid has the molecular weight of 800,000~200,000,000 Daltons. The collagen and hyaluronic acid are mixed at the volume rate of 1:1~2:1. GAG(Glucosaminoglycan) is added at the rate of 1:0.1~1:0.5 for the hyaluronic acid. The GAG is selected from a group comprising chondroitin, chondroitin sulphate, heparin, and heparin sulfate.
    • 提供一种多孔胶原 - 透明质酸复合材料及其制造方法,以最大限度地减少移植复合材料的排斥,确保优异的机械性能和组织相容性,并使制造工艺简单。 通过在3.0〜5.0的pH下混合胶原和透明质酸,然后将骨料冻干而形成骨料,从而制造多孔胶原透明质酸复合材料。 使用Atelo胶原蛋白或可溶性胶原蛋白。 透明质酸的分子量为800,000〜200,000,000道尔顿。 胶原蛋白和透明质酸以1:1〜2:1的体积比混合。 对于透明质酸,加入GAG(葡萄糖胺聚糖)的比例为1:0.1〜1:0.5。 GAG选自软骨素,硫酸软骨素,肝素和硫酸肝素组。
