Abstract

The aim of the present study is to investigate the anti-inflammatory effect of a vegetable soup (VS). The present study was designed to determine the effect of the vegetable soup on pro-inflammatory factors such as NO, iNOS and TNF-$\alpha$ in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. The cell toxicity was determined by MTS assay. To evaluate the anti-inflammatory effect of vegetable soup, amount of NO was measured using the NO detection kit and the iNOS expression was measured by reverse transcriptase polymerase chain reaction (RT-PCR). Also, proinflammatory cytokines were measured by ELISA kit. The results showed that the vegetable soup reduced NO, iNOS and TNF-$\alpha$ production without cytotoxicity. Our results suggest that the vegetable soup may have an anti-inflammatory property through suppressing inflammatory mediator productions and appears to be useful to develop the functional food realted to anti-inflammation.

본 연구의 목적은 일상생활에서 쉽게 섭취할 수 있는 당근, 무, 무청, 우엉, 표고버섯을 재료로 한 야채 스프의 항염증성을 검토하기 위한 것으로, RAW264.7 세포에서 LPS에 의해 유도되는 염증물질 중 NO와 염증성 사이토카인 TNF-$\alpha$에 대한 억제력을 관찰하였다. 실험결과 실험에 사용된 야채스프는 세포독성을 나타내지 않았다. 세포독성이 없음을 확인 한 후 LPS로 처리한 RAW264.7 세포에서 야채스프의 NO 생성억제를 평가한 결과 RAW264.7 세포만 배양한 대조군에서 NO의 농도는 매우 낮게 측정되었으며, LPS를 처리한군에서 NO의 농도는 현저히 증가되었다. 또한 야채스프를 처리한 실험군은 NO 생성이 유의성 있게 억제되었으며, RAW264.7 세포를 LPS로 처리 시 iNOS가 발현되어 NO를 생성하게 되므로 iNOS의 발현에 미치는 영향을 평가하였다. LPS 처리 시 iNOS 유전자 발현이 유의하게 증가되었으나, 야채스프를 전 처리한 실험군에서 iNOS의 양이 감소하였다. 야채스프에 의한 iNOS의 발현억제는 NO 생성억제를 유도를 의미한다. Proinflammatory cytokines인 TNF-$\alpha$ 분비 억제를 살펴본 결과 LPS를 처리한 군에서 TNF-$\alpha$의 분비가 현저하게 증가되었으나 야채스프를 처리한 군에서는 유의한 억제를 나타냈다. 이상과 같이 야채스프는 RAW264.7 세포에서 LPS에 의해 유도되는 NO의 생성억제, iNOS의 발현을 억제시켰으며, proinflammatory cytokines인 TNF-$\alpha$의 분비량도 억제시켰다. 이는 야채수프의 항염증성을 입증하기 위한 기초자료로 활용이 가능하다고 사료된다.
