초록
본 연구는 RAW264.7 대식세포에 대한 우슬과 땅두릅 복합 열수추출물(1 : 2, 1 : 3, 1 : 5, 2 : 1, 3 : 1 및 5 : 1 비율)의 항염증 효과를 조사했다. 세포 독성은 CCK 분석을 사용하여 확인하였다. 우리는 ELISA 키트를 사용하여 IL-1β, IL-6 및 TNFα를 측정함으로써 우슬 및 땅두릅 복합 열수추출물의 항염증 효과를 평가하였다. 우슬 및 땅두릅 복합 열수추출물은 LPS로 자극된 RAW264.7 대식세포에서 IL-1β 및 TNFα를 유의적으로 억제하였다. 복합 추출물의 다양한 비율을 비교하였을 때, 2 : 1 비율은 LPS로 유도된 RAW264.7 세포에서 훨씬 더 효능이 있었고 TNFα의 생성 또한 억제하였다. 본 연구의 결과는 우슬 및 땅두릅 복합 열수추출물이 RAW264.7 대식세포에 대해 강력한 항염증 효과를 갖는 다는 것을 보여주며, 이들 추출물은 염증 질환 예방을 위한 기능성 식품의 좋은 공급원이 될 수 있다고 사료된다.
This study investigated the anti-inflammatory effects of mixed extracts of Achyranthes japonica Nakai (Aj) and Aralia continentalis Kitagawa (Ac) (ratios of 1 : 2, 1 : 3, 1 : 5, 2 : 1, 3 : 1 and 5 : 1) on RAW264.7 macrophages. Cell toxicity was determined using a cell counting kit (CCK) assay. We evaluated anti-inflammatory effects of the mixed extracts of Aj and Ac by measuring interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)α using an enzyme-linked immunosorbent assay (ELISA) kit assay. The mixed extracts of Aj and Ac inhibited lipopolysaccharide (LPS)-induced IL-1β and TNFα in LPS-stimulated macrophages. Comparing different ratios of the mixed extracts, the 2 : 1 ratio of Aj and Ac has much more potency and inhibited the production of TNFα in LPS-induced RAW264.7 cells. The results of the present study showed that the mixed extracts of Aj and Ac have potential anti-inflammatory effects on RAW264.7 macrophages. Therefore, these extracts may be used as a good source of functional foods for the protection against inflammatory diseases.
