Abstract

단삼(丹蔘) (Salvia miltiorrhiza)은 꿀풀과(일과(―科) Lamiaceae)에 속하는 다년생 초본으로, 중국이 원산지이며 약용하기 위해 우리나라에서도 널리 재배하고 있다. 신농본초경(神農本草經) 상품(上品)에 수재(收載)되어 있으며, 거어지통(祛瘀止痛), 양혈소종(凉血消腫), 청심제번(淸心除煩), 활혈조혈(活血調血) 등의 효능이 있어 부인과 질환에 많이 사용되고 있는 약재에 속한다. 본 연구에서는 단삼(丹蔘) 추출물이 흰쥐의 흉부 대동맥 절편에 어떠한 양상으로 작용하는지 확인하고자 하였으며, 그 결과 단삼 추출물 특히 헥산 분획에서 강력한 혈관 이완 작용이 나타났으며, 혈관 내피 세포의 존재 유무에 상관없이 농도 의존적으로 혈관을 이완시켰으나 혈관 내피 세포가 존재하는 상황에서 더욱 강력한 혈관 이완 작용을 보였다. 이러한 과정에 NO에 의한 cGMP 증가가 주요하게 작용하는 것으로 추정되었으며, 칼슘 통로 차단 효과에 의한 세포 내 $Ca^{2+}$의 감소도 관여하는 것으로 생각된다.
