Helicobacter pylori에 의한 위세포독성 및 interleukin-8 생성에 미치는 무의 억제효과

Abstract

무(한국 품종 및 일본 품종)를 사용하여 H. pylori에 의한 위세포독성 및 IL-8생성에 미치는 영향을 살펴보았다. 그 결과 무는 H. pylori에 의한 위세포독성을 농도의존적으로<TEX>$(2\~10 mg/ml)$</TEX> 억제하였으며 또한 위암세포인 KATO III에서 분비되는 IL-8의 생성을 억제시킴<TEX>$(5\~10mg/ml)$</TEX>을 알았다. 이러한 사실은 무가 H. pylori감염에 의한 위점막세포의 손상을 방지할 수 있음을 나타낸다. The efforts of Korean and Japanese radishes on the viability and interleukin (JL)-8 production by Helicobacter pylori were investigated in human gastric epithelial cell. Cell viability was significantly decreased when they were incubated with H. pylori toxin (p <0.05, p<0.01 and p<0.005). Co-incubation with Korean or Japanese radish increased H. pylori toxin-inhibited cell growth in a concentration-dependent manner. The production of IL-8 was greatly increased in H. pylori-infected gastric epithelial cell in concentration- and time-dependent manners. The increased production of IL-8 was significantly inhibited by Korean (p<0.05 and p<0.01) or Japanese (p<0.05) radishes <TEX>$(5\~10mg/ml)$</TEX>. These results indicate that Korean and Japanese radishes have protective effects on H. pylori-inhibited cell growth and H. pylori-induced gastric mucosal cell inflammation by suppressing the production of inflammatory cytokine (IL-8) from gastric epithelial cell.
