산벚나무의 주요성분과 활성으로 어떤 것들이 밝혀졌는가? | 산벚나무 (Prunus sargentii)는 장미과 (Rosaceae) 벚나무속(Prunus)에 속하는 식물로, 산벚나무의 수피와 가지는 벚나무(Prunus serrulata), 왕벚나무 (Prunus yedoensis)의 수피와 함께 화피 (樺皮) 또는 앵피 (櫻皮)라는 생약재로 염증성 질환이나 피부 관련 질환에 빈번히 이용되어 왔다 (Shin, 2006).Sakuranin, aringenin, taxifolin, pinostobin 등이 지금까지 밝혀진 주요성분으로, 관련된 활성으로는 항산화 활성과 면역억제 활성, 항염증 활성, 피부 미백 활성, 항균활성 등이 연구되어 왔다 (Kang, 2007; Lee et al., 2001; Park et al. | |
Propionibacterium acnes는 무엇인가? | Propionibacterium acnes는 여드름의 주 원인균으로 혐기성세균이며 피부 안쪽 또는 피지선에 존재한다. 청소년기 호르몬 활동이 증가하고 피지선의 분비가 활발할 때 P. | |
피부에 영향을 미치는 요인은 크게 어떤 것들로 나뉘는가? | 피부는 외부 자극으로부터 신체를 보호하는 기관으로 체온조절 작용, 에너지 저장 작용, 분비 및 흡수 작용, 비타민 D 합성 등의 많은 역할을 수행하고 있지만, 스트레스 및 외부자극에 노출될 경우 1차적으로 가장 손상 받기 쉬운 부분이기도 하다. 피부에 영향을 미치는 요인으로는 생물학적 원인, 물리적 원인, 화학적 원인, 면역학적 원인으로 크게 구별된다(Park and Choi, 2011). 그중에서 여드름은 모낭-피지선단위의 만성 염증성 질환으로 얼굴, 등, 어깨, 목에 주로 나타나며 사춘기 청소년의 85%에서 관찰되며, 20대 중반부터 소실되지만 최근에는 성인기 여드름이 증가하는 경향을 보인다. |
