삼채 뿌리 메탄올 추출물이 LPS가 유도된 RAW264.7 세포에 대한 항염증 효과 = 연구노트

국문 초록 (Abstract)

본 연구에서는 삼채 뿌리 메탄올 추출물의 항염증 효과를 확인하기 위하여 마우스 대식세포인 RAW264.7 세포에 LPS를 처리한 결과 세포 생존율은 다양한 농도의 삼채 뿌리 메탄올 추출물에서 세포독성이 없는 것으로 나타났다. 삼채 뿌리 메탄올 추출물은 다양한 농도에서 LPS만을 처리한 대조군과 비교하였을 때, NO 생성을 농도 의존적으로 감소시키는 것으로 확인되었다. 또한 염증성 사이토카인인 TNF-α와 IL-6의 생성양 역시 LPS만을 처리한 군과 비교했을 때, 각각의 농도에서 농도의존적으로 감소하는 경향을 보였다. 본 연구에 사용된 삼채 뿌리 메탄올 추출물의 염증 억제 기작에 관한 추가적인 연구의 수행과 활성물질의 동정에 관한 연구가 추가로 이루어져야겠지만, 본 연구의 결과는 삼채뿌리 메탄올 추출물은 NO 및 염증성 사이토카인의 생성을 조절함으로써 대식세포 유래의 염증 반응을 효과적으로 억제하고, 염증성 매개질환에 탁월한 효능이 있을 것으로 사료되며, 예방물질로서 활용될 수 있을 것으로 기대된다.

다국어 초록 (Multilingual Abstract)

Allium hookeri, a member of the onion family, has long been mainly cultivated for food and medicinal use in Southeast Asia countries owing to its various biological properties. However, no studies of the anti-inflammatory effects of A. hookeri extracts have been conducted to date. Therefore, this study was investigated the potential of the methanol extract of A. hookeri to suppress the inflammation in lipopolysaccharide (LPS)-induced mouse macrophage RAW264.7 cells. This study was performed on macrophage cells that were pretreated with 0～500 μg/mL of methanol extract of A. hookeri root prior to LPS treatment. Treatment with methanol extract of A. hookeri root significantly inhibited LPS-induced nitric oxide formation in dose-dependent manner. Treatment of A. hookeri root also significantly decreased LPS-induced TNF-α and IL-6 production. The results of this study provide new evidence of the anti-inflammatory properties of A. hookeri and indicate that it may have a potential therapeutic use for the prevention and treatment of macrophage derived chronic immune diseases.
