조직공학용 생체 물질로 사용하고자 가교제 1,3-butadiene diepoxide (BD)를 사용하여 락타이드와 가교시킨 히아루론산 막을 제조하였다. 막의 락타이드 및 BD 반응도는 핵자기 공명 분광볍으로 결정하였다. BD 농도가 높을 경우 6%이하의 성장저해 현상이 나타났으나 그 값은 세포 성장에 문제되지 않을 정도로 충분히 낮았다. 가교온도가 낮을수록 탄성 율은 증가하고 팽윤도는 감소하였다. 막의 생분해속도는 가교온도가 낮을수록 감소하였다. 약물방출 실험 결과 가교 온도가 낮을수록 막을 통한 약물 투과는 감소하였다.
The biodegradable hyaluronic acid membranes cross-linked with lactide using the crosslinking agent, 1,3-butadiene diepoxide (BD), were prepared as a potential biocompatible material for tissue engineering. The degree of lactide and BD reaction of the crosslinked membrane was determined by the analysis of nuclear magnetic resonance spectroscopy 6% of growth inhibition was observed in case of high BD concentration but the value is low enough not to affect cell growth. As the crosslinking reaction temperature increased, elongation increased and swelling ratio decreased. The rate of degradation was found to increase with the crosslinking temperature. The drug release experiment showed that the transport of drug through the membrane decreased with the crosslinking temperature.
