Abstract
Description
도 2는 NR1, NR2 및 NR3 이 HIF-1α와 VEGF의 단백질 발현에 미치는 효과를 나타낸 것이다.
도 3은 NR1, NR2 및 NR3 이 혈관내피세포에서 신혈관 생성에 중요한 형태학적 변화인 Tube formation에 미치는 효과를 나타낸 것이다.
도 4는 NR1, NR2 및 NR3 이 human dermal fibroblast (HDF)에서collagen 1A2, fibronectin 과 IF-1α의 단백질 발현에 미치는 효과, 및 collagen 1A2, fibronectin과 VEGF의 전사 활성에 미치는 효과를 나타낸 것이다.
도 5는 NR2와 NR3이 HDF에서 세포 이동 (migration)에 미치는 효과를 시간대 별로 나타낸 것이다.
도 6은 NR3가 동물 실험시 wound healing에 미치는 효과를 기제 및 시판 연고제 (후시딘, 동화약품)와 비교하여 상처크기 감소율로 나타낸 것이다.
도 7은 NR3가 동물 실험시 wound healing에 미치는 효과를 현미경을 통해 낙설된 상피 부분, 육아 조직에서 신생모세혈관 및 침윤 염증세포, 또한 콜라겐 발현률을 조직병리학적으로 관찰한 결과를 나타낸 것이다.
