The biological activities of Platycodon grandiflorum (PG) root extracts have been studied intensively, whereas there are limited number of studies on PG seed extract (PGSE). PGSE was prepared by ethanol extraction, and its antidiabetic effect was evaluated in mice with type 2 diabetes (C57BLKS/J-db/...

제2형 당뇨 환자수의 현황은? | 또한, 인슐린 저항성은 지질 대사의 이상을 일으켜 중성 지방을 상승시키며, 고혈압으로의 진행을 촉진하고 혈류의 흐름을 방해하는 체내 대사의 총체적 교란의 원인이 된다(Shulman, 2000). 전체 당뇨환자의 약 90%를 차지하는 제2형 당뇨 환자수는 비만 환자의 증가와 함께 지속적으로 증가하고 있으며 중국, 인도를 비롯한 개발도상국의 당뇨 유병율은 매우 빠른 속도로 증가하고 있다(Chen 등, 2012). | |
대사증후군(Metabolic syndrome)이란? | 대사증후군(Metabolic syndrome)이란 복부비만, 당뇨, 콜레스테롤, 고혈압, 중성지방 등 5가지 지표 중 3가지 이상이 기준치를 초과한 상태를 말하며 그 기전은 인슐린 저항성(insulin resistance)으로 보고되었다(Park 등, 2003). 인슐린 저항성이란 일반적으로 포도당 섭취, 당 대사, 포도당 저장에 대한 인슐린의 내성을 의미하는데, 제2형 당뇨에서 인슐린 저항성은 인슐린 자극에 의한 골격근에서의 포도당 흡수 및 대사 감소를 초래하여 혈당을 증가시키는 중요한 원인이 된다. | |
대사 증후군 치료 연구에 종자 추출물을 사용하는 이유는? | 일반적으로 식물의 종자는 발생에 필요한 정보를 보호하기 위한 생체물질을 함유하고 있으며 생육이 어려운 건조, 저온 및 높은 염도 조건과 같은 외부 환경 조건에 대한 높은 저항을 위한 polyphenol 등을 다량 함유하고 있다(Tsao, 2010). 종자 추출물 중 가장 연구가 많이 진행된 소재는 포도 종자 추출물로 다양한 효능의 평가가 진행되었으며, 이 중 Sivaprakasapillai 등(2009) 은 대사 증후군을 겪고 있는 40세 이상 성인 27명을 대상으로 한 연구에서 포도씨 종자 추출물을 하루에 150 mg 이상 섭취 시 혈압을 유의적으로 감소시킨다고 보고하였다. |
