The anti-inflammatory effects of Sargassum fulvellum water extracts (SFWE) were investigated using lipopolysaccharide (LPS)-induced inflammatory response in this study. To examine the potential anti-inflammatory properties of SFWE, the NO, TNF-α, IL-6, IL-1β, and cell proliferation were measured. It was confirmed that the NO and TNF-α secretion were significantly suppressed when SFWE was added to LPS-stimulated RAW 264.7 cells. Moreover, the expression of IL-6 and IL-1β cytokines was suppressed by SFWE in a dose-dependent manner. Especially, IL-6 inhibition activities were over 50% at 1% of SFWE. The cytotoxicity of SFWE and the proliferation of macrophages was measured by MTT assay. As a result, there was no cytotoxicity in the macrophage proliferation treated with SFWE compared to the control. In conclusion, these results suggested that the SFWE may have significant effects on inflammatory factors and can be a potential anti-inflammatory therapeutic materials.

사람의 질병은 여러 요인의 복합적인 작용으로 발생하는데 이 중 유전적인 요인에는 유전자 간의 상호작용을 들 수 있다. 마이크로어레이(Microarray) 데이터로부터 유전자의 활성화 및 억제 관계를 밝히려는 다양한 시도는 계속되어왔다. 그러나 마이크로어레이 자체가 갖는 불안정성과 실험조건 수의 제약이 커다란 장애가 되어 왔다. 이에 생물학적 사전 지식을 포함하는 방법들이 제안되었다. 본 논문에서는 질병과 관련된 유전자 간의 상호작용의 집합을 질병 모듈이라 정의하고 이를 유전자 알고리즘으로 학습한 베이지안 네트워크(Bayesian network)로 추론하는 방법을 제안한다.

The anti-inflammatory effects of Undaria pinnatifida water extract (UPWE) were investigated using lipopolysaccharide -induced inflammatory response in this study. To examine the potential anti-inflammatory properties of UPWE, the cell proliferation, nitric oxide (NO), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α) and IL-1β were measured. As a result, there was no cytotoxicity in the macrophage proliferation treated with UPWE compared to the control. NO levels decreased with increasing concentration of UPWE. Moreover, the secretion of IL- 6, TNF-α and IL-1β were suppressed in a dose-dependent manner, and IL-6 inhibition activities were over 50% at 0.1%. These results suggested that UPWE may have significant effects on inflammatory factors and be a potential anti-inflammatory therapeutic materials.
