초록

뽕잎으로부터 분리한 H. pylori 억제물질이 건강기능식품으로 산업화되기 위하여 이들 유용성분이 생체 내에서 약리성을 가지는지 여부를 검토하였다. 청목노상으로부터 분리한 혼합물은 $200{\mu}g/100{\mu}L$의 농도에서 H. pylori에 대한 저해 clear zone을 형성하여 항균활성을 나타내었고, C57BL/6종 mouse에 H. pylori의 감염을 유도 한 결과 6주 이상이 되어야 H. pylori의 감염이 되는 것을 확인하였으며, 이 때 감염균수는 평균 $8{\times}10^5$ CFU/mL이었다. 경구투여를 통해 청목노상뽕잎에서 추출한 유효성분의 혼합물이 H. pylori 감염에 있어 예방 및 치료 효과를 갖는지 시험한 결과, 절개된 위속의 H. pylori colony 수가 약물투여 군에서 대조군에 비해 감소한 것을 확인하였다. 마우스의 혈청을 분리하여 immunoglobulin isotype을 측정한 결과, 대조군 보다 IgG1, IgA 등이 높게 생성되는 것이 확인되었고, 시료 혼합물에 의해 항체생성이 증가되어 H. pylori 감염을 억제하는 것으로 판단되었다. 이러한 결과로 뽕잎에서 추출한 유용성분인 caffeic acid, rosemarinic acid와 chlorogenic acid가 H. pylori의 감염에 있어서 예방 또는 치료효과가 있는 것으로 확인되었다. 따라서 H. pylori에 의해 유발되고 감염률이 증가되고 있는 위염, 위궤양, 위암의 예방과 치료가 가능할 것으로 판단되었다.

Inhibitory effect of useful components from Cheongmoknosang mulberry leaves extracts against Helicobacter pylori were investigated to develope them to a health functional food. It was confirmed that H. pylori bacterial infection occurred after 6 weeks over in C57BL/6 mouse which was caused the infection, and the average number of pathogens was $8{\times}10^5$ CFU/mL. Effects of the prevention and cure against H. pylori were tested by the mouth administration with Cheongmoknosang mulberry leaves extracts include the active ingredient, and number of H. pylori colony in stomach of drug groups were decreased more than control group. The result of testing immuno-glogulin isotype from the separated serum from a mouse, IgG1, IgA produced more in administered group, and it is expected to inhibit the H. pylori infection because of increasing antibody production in the mixture. These results suggest that caffeic acid, rosemarinic acid and chlorogenic acid in Cheongmoknosang mulberry leaves extracts are very effective to prevent or cure against H. pylori infection. So the ratio of infection is increasing and it is regarded to be able to prevent and cure the disease like gastritis, gastric ulcer and gastric cancer which are caused by H. pylori.
