【摘要】 以壳聚糖、胶原为主要原料 ,研制一种新型的创伤敷料 ,并对其在临床上的应用进行初步的探讨。首先制备高纯度的胶原蛋白溶液 ,使之与壳聚糖溶液键合 ,冷冻干燥成为海绵体。然后进行毒理学检测 ,包括急性毒性试验、刺激性试验、过敏性试验和溶血性试验 ;并在骨科的开放性创面上进行了临床试验。壳聚糖 -胶原海绵的毒理学试验均呈阴性 ,在临床上有促进创面愈合 ,阻止渗液溢出的功效。因此 ,所研制的壳聚糖—胶原海绵无毒副作用 ,具有良好的临床疗效 ,具备推广应用的前景更多还原

【Abstract】 We have prepared a wound dressing made from chitosan and collagen. Its clinical curative effect was detected. Chitosan solution was put into purified collagen solution. Then, the solution became sponge by means of freeze drying, and it was subjected to a series of toxicology tests, including acute toxicity, stimulation test, allergic and hemolysis tests, as well as the clinical test of openning trauma in orthopedics. All of the results of toxicology tests were negative. The chitosan collagen sponge could not only accelerate the speed of curing but also restrain the extravasate. Therefore, the chitosan collagen sponge has good biocompatibility and clinical curative effect. It is a prospective security biomaterial for medical use.更多还原
