누리장나무의 잎과 줄기는 예로부터 항고혈압, 관절염, 류마티스 관절염, 항염증 등을 치료하는 민간약재로 사용되어 왔다. 본 연구에서는 누리장나무의 잎 추출물과 그 분획물의 항산화 및 항염증 소재로서의 활성가능성을 확인하기 위하여 수행되었다. 누리장나무 잎의 ethanol (EtOH)로 추출물과 이 추출물을 분획하여 얻은 hexane, chloroform ($CHCl_3$), ethyl acetate (EtOAc), n-butanol (BuOH) 분획물들의 총 폴리페놀 함량을 비교한 결과, 총 폴리페놀 함량은 EtOAc 분획물($78.08{\mu}g/mg$)과 BuOH 분획물($77.54{\mu}g/mg$)에서 높게 측정되었다. 각 분획물의 항산화 활성을 비교한 결과, 폴리페놀 함량이 높은 EtOAc 분획물과 BuOH 분획물에서 높은 DPPH (1,1-diphenyl-2-picrylhydrazyl) 및 ABTS (2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid)) radical 소거활성을 나타내었다. 그리고 xanthine oxidase 저해활성은 $CHCl_3$ 분획물($IC_{50}=4.43{\mu}g/ml$)과 EtOAc 분획물($IC_{50}=5.69{\mu}g/ml$)에서 높게 나타났다. EtOAc 분획물은 RAW 264.7 세포에서 lipopolysaccharide (LPS)로 유도된 nitric oxide (NO)의 생성을 효과적으로 억제하였다($IC_{50}=18.87{\mu}g/ml$). 또한, EtOAc 분획물($100{\mu}g/ml$)은 LPS로 지극한 RAW 264.7 세포에서 tumor necrosis factor ${\alpha}$ ($TNF-{\alpha}$)와 interleukin-6 (IL-6)의 생성과 inducible nitric oxide synthase (iNOS)와 cyclooxygenase-2 (COX-2) 단백질의 발현을 효과적으로 억제하였다. 본 연구결과는 누리장나무 잎 추출물과 분획물이 항산화 및 항염증 소재로서의 활용가능성이 있음을 제시해 준다.

봉독은 동양의학에서 관절염, 류마티즘 및 각종 암을 포함하여 다양한 질병을 치료하기 위하여 이용되었다. 최근 봉독의 신생혈관 억제효과에 대한 연구가 보고되었으나 정확한 분자메커니즘에 대해서는 보고가 미흡하다. 따라서, 본 연구는 봉독이 인간결장암세포인 HCT116세포에서 신생혈관생성과 종양진행에 중요한 역할을 하는 HIF-$1{\alpha}$와 VEGF 발현 억제효과를 조사하였다. 그 결과 봉독은 $CoCl_2$로 유도한 저산소 상태에서 VEGF와, HIF-$1{\alpha}$의 발현을 감소시키며 HIF-$1{\alpha}$의 promoter 영역인 HRE 활성을 억제하였다. 이러한 봉독의 HIF-$1{\alpha}$ 발현억제효과는 ERK1/2의 인산화 조절을 통한 것이며, 봉독은 p38, JNK, AKT의 인산화에는 영향을 끼치지 않았다. 또한 봉독의 효과를 나타내는 단일물질 탐색을 위해 봉독의 생리활성 물질로 알려진 아파민과 멜리틴을 조사한 결과, HIF-$1{\alpha}$와 VEGF 억제효과는 아파민에 기인하는 것이라고 예상 할 수 있었다. 이와 같은 결과를 통하여 본 연구에서는 봉독의 혈관신생 억제에 대한 새로운 신호전달기전 및 인간 결장암세포 전이 억제제로서의 잠재성을 확인하였다.

본 연구는 시험물질 국내산 땃두릅나무 추출물의 반복 경구투여에 의한 독성을 질적 ${\cdot}$ 양적으로 평가하기 위하여 식품의약안전청의 의약품 등의 독성시험기준에 따라 Sprague-Dawley 계열의 암 ${\cdot}$ 수 흰쥐에 시험 물질을 0, 500, 1,000 및 2,000 mg/kg의 용량으로 14일간 반복경구 투여한 후 사망률, 일반증상, 체중변화, 혈액 및 혈액생화학적 변화, 부검소견, 조직학적인 변화를 관찰하였다. 시험기간 중 암 ${\cdot}$ 수 모든 군에서 시험물질 투여에 기인한 일반적인 증상변화는 관찰되지 않았고, 시험불질의 반복 투여로 인한 사망례 역시 관찰되지 않았다. 시험물질의 투여에 기인한 유의적인 체중감소 또한 나타나지 않았으며, 상기 이외의 육안적인 부검소견에서도 시험물질 투여에 기인한 어떠한 이상소견도 발견되지 않았다. 혈액학적 분석 결과 일부 시험물질 투여군에서 WBC, MCHC, PLT의 수치가 유의적인 변화를 보였으나, 정상범위 내에서의 변화로 시험물질에 의한 독성이라고 판단하기는 어렵다. 혈청중의 ALP 및 뇨의 BUN의 유의적인 감소가 시험물질 투여군에서 관찰되었으나 정상 생리 범위 내에서의 변화로 시험 물질에 의한 독성이라 판단 하기는 어렵다. 간장과 신장의 조직학적인 관찰에서 시험물질 투여에 의한 변화는 관찰되지 않았다. 본시험결과는 흰쥐에서 땃두릅나무 에단올추출물의 14일 반복경구 투여는 2,000 mg/kg 이하의 용량에서 어떠한 독성영향도 유발하지 않았으며, 본 시험 조건하에서 최소치사량은 2,000 mg/kg 이상이라는 것으로 나타났다. 따라서 본 시험을 통하여 땃두릅나무 추출물은 투여가능 최대 용량에서도 독성이 없는 안전한 천연물이라는 것을 확인하였고, 의약품이나 기능성식품으로서의 개발 가능성을 확인하였다.

Background and Purpose : This study shows the clinical effects on treatment with Rheumatoid arthritis using Aqua-acupuncture such as Ursi Fel Bovis Calculus and Cathami Flos that are known for which have anti-inflammatory and analgesic effects. Objective and Methods : This study has been carried out Aqua-acupuncture treatment such as Cathami Flos and Ursi Fel Bovis Calculus twice or three times a week with patients diagnosed as rheumatoid arthritis on 7 criteria of US Rheumatism Academy. Results : 1. If you see the sexual distribution, it shows the rates of male and female 1: 1.83. Age distribution shows as age ascend it shows high. 2. If you see the duration distribution, it shows chronic tendency in order of more than 6 months(63.3%), 2 to 5 months, and I month. 3.

Background: To evaluate the therapeutic benefits of the treat-to-target (T2T) strategy for Asian patients with early rheumatoid arthritis (RA) in Korea. Methods: In a 1-year, multicenter, open-label strategy trial, 346 patients with early RA were recruited from 20 institutions across Korea and stratified into 2 groups, depending on whether they were recruited by rheumatologists who have adopted the T2T strategy (T2T group) or by rheumatologists who provided usual care (non-T2T group). Data regarding demographics, rheumatoid factor titer, anti-cyclic citrullinated peptide antibody titer, disease activity score of 28 joints (DAS28), and Korean Health Assessment Questionnaire (KHAQ) score were obtained at baseline and after 1 year of treatment. In the T2T group, the prescription for disease-modifying antirheumatic drugs was tailored to the predefined treatment target in each patient, namely remission (DAS28 < 2.6) or low disease activity (LDA) ($2.6{\leq}DAS28$ < 3.2). Results: Data were available for 163 T2T patients and 162 non-T2T patients. At the end of the study period, clinical outcomes were better in the T2T group than in the non-T2T group (LDA or remission, 59.5% vs. 35.8%; P < 0.001; remission, 43.6% vs. 19.8%; P < 0.001). Compared with non-T2T, T2T was also associated with higher rate of good European League Against Rheumatism response (63.0% vs. 39.8%; P < 0.001), improved KHAQ scores (-0.38 vs. -0.13; P = 0.008), and higher frequency of follow-up visits (5.0 vs. 2.0 visits/year; P < 0.001). Conclusion: In Asian patients with early RA, T2T improves disease activity and physical function. Setting a pre-defined treatment target in terms of DAS28 is recommended.
