Abstract

This study investigated the effect of mulberry fruit extract(MFE) on antioxidant and anti-inflammatory activities of middle aged women with rheumatoid factor (RF). Thirty two middle-aged subjects were divided into two groups which were normal middle-aged group (NMG) and abnormal middle-aged group whose serum RF level were > 10 u/mL (AMG). All groups had consumed MFE (100 mL/day) for 4 weeks. Anthropometric measurements, serum inflammatory factors, serum oxidative stress markers analyses were performed at baseline and then at 4 weeks following the study. There were no significant differences in anthropometric measurements, including BMI, WHR and body fat composition between two groups. But after 4 weeks MFE consumption, serum levels of C-reactive protein (CRP), ferric-reducing ability of plasma (FRAP), serum TNF-${\alpha}$, IL-2, IL-4 had significantly decreased (p<0.05) in AMG. These findings suggested that the MFE consumption as food may be protective against oxidation and inflammation like RA.

본 연구의 목적은 오디가 류머티스 요인(Rheumatoid Factor: RF>10 u/mL)이 있는 중년여성의 혈중 항산화 및 항염증 지표수준에 미치는 영향을 알아보고자 32명의 중년여성을 2군 (NMG, AMG)으로 나누어 4주간의 오디 추출물 투여 전ㆍ후로 체성분 측정 및 채혈을 통하여 혈청 산화(TBARS, FRAP) 및 염증성 지표물질(요산, C-reactive protein: CRP, RF 및 homocystein) 농도를 분석 및 비교하였다. 연구결과 오디 추출물 투여에 따른 NMG와 AMG간의 체성분에는 차이가 없었다. AMG의 CRP 수준은 $0.80{\pm}0.05$ mg/dL에서 $0.55{\pm}0.02$ mg/dL로 유의적으로 감소하였다(p<0.05). AMG의 오디 추출물 투여 전의 혈청 TBARS 수준($63.04{\pm}12.20$ mol/L)은 투여 후($57.44{\pm}11.16$ mol)와 유의적인 차이는 없었으나, 감소하는 경향을 보였다. AMG의 혈청 FRAP 수준은 급여 전($1239.02{\pm}63.22$ mol)에 비해 급여 후($1556.21{\pm}11.16$ mol) 유의적으로 증가되었다(p<0.05). AMG의 혈청 TNF-${\alpha}$가 $8.78{\pm}0.12$ pg/mL에서 $6.58{\pm}0.16$ pg/mL로, IL-2 수준은 $5.41{\pm}0.71$ pg/mL에서 $3.94{\pm}0.03$ pg/mL로, IL-4 수준은 $7.21{\pm}0.61$ pg/mL에서 $5.15{\pm}0.36$ pg/mL로 감소하여 오디 추출물 투여에 의한 항산화 및 항염증 활성이 규명되었다. 이상의 연구결과로 볼 때 오디는 류머티즘 요인이 있는 중년여성의 항산화 및 항염증 활성을 강화시키는데 도움이 된 것으로 보인다. 따라서 산화 스트레스 감소를 통한 염증조절물질로써 오디를 꾸준히 섭취한다면 류머티스 관절염(Rheumatoid Arthiritis: RA)환자의 질병관리에 부작용 없이 도움이 될 것으로 사료된다. 본 연구를 기초로 후속적으로 RA 발병 유발인자인 사이토카인을 효과적으로 통제할 수 있는 오디를 활용한 치료식 개발 및 보급을 활성화하여 국내 오디 농가의 부가가치 창출에도 기여할 수 있을 것으로 기대된다.
