Abstract:
본 발명은 인간을 제외한 동물의 소장점막하조직을 가교제와 반응시켜 가교결합이 형성된 생체 내 분해기간이 조절가능한 생체적합성 소장점막하조직 시트 및 이의 제조방법을 제공한다. 본 발명에 따른 생체적합성 소장점막하조직 시트는 가교제의 가교결합에 의해 생체 내 분해기간을 지연시킬 수 있으며, 가교제의 종류 및 가교 시간에 따른 가교결합의 형성 정도에 따라 분해기간을 조절할 수 있으므로, 조직공학용 지지체, 약물전달체, 창상드레싱 또는 지혈제로서 매우 유용하게 사용할 수 있다.

Abstract:
The present invention relates to a polyester block copolymer whose mechanical property and biodegradation period are adjustable, the polyester block copolymer which has various functional groups in side chain or a chain end. The polyester block copolymer of the present invention is suitable for the human body and has mechanical properties and half life of biodegradation which are adjustable, thereby resolving adsorption of the protein in the body when applied to the human body and side effect from accumulated products of hydrolysis.
Abstract:
The present invention provides a biocompatible small intestinal submucosa sheet having adjustable in vivo degradation time in which the small intestinal submucosa of an animal reacts with a crosslinking agent to form a crosslinked bond. The present invention also provides a method for preparing the biocompatible small intestinal submucosa sheet. The biocompatible small intestinal submucosa sheet according to the present invention may delay in vivo degradation time by the crosslinked bond of the crosslinking agent, and may adjust the degradation time depending on the degree of formation of the crosslinked bond based on the type of the crosslinking agent and crosslinking time. Therefore, the biocompatible small intestinal submucosa sheet according to the present invention can be significant and valuably used as a scaffold for tissue engineering, a drug carrier, wound dressing or an antihemorrhagic agent.
