류마티스 관절염 동물 모델에서 활막의RANKL/OPG mRNA 발현 비율 및 IL-17의 효과
이준희,김근태,류선,김주인,백승훈,김성일 대한류마티스학회 2006 대한류마티스학회지 Vol.13 No.4
Objective: To investigate the synovial mRNA expression of receptor activator of NFκB (RANK), RANK ligand (RANKL), osteoprotegerin (OPG) and RANKL/OPG mRNA expression ratio, and to evaluate the effects of IL-17 in experimental rheumatoid arthritis (RA) model. Methods: After induction of collagen-induced arthritis (CIA) by type II collagen in DBA1 mice, mice were anesthetized at day 28 and a small aperture in the skin of the knee was performed. Mice, in which arthritis of knee was present, were selected and divided into 3 groups, and phosphate-buffered saline (PBS group), IL-17 (IL-17 group) or anti-IL-17 monoclonal antibody (anti-IL-17 group) was injected to both knee joint at day 28 and 32. At day 35, mice were sacrificed and synovium of knee joints were isolated. Synovial mRNA expression of RANKL, RANK and OPG was assessed by real-time RT-PCR and immunohistochemical stain. Results: Synovial RANKL and RANK mRNA expressions were significantly different among IL-17, PBS, anti-IL-17 and normal group (IL-17>PBS>anti-IL-17>normal group), and synovia OPG mRNA expressions in PBS, IL-17 and anti-IL-17 group were significantly high than those in normal group, however, there was no significant difference among IL-17, PBS and anti-IL-17 group. RANKL/OPG mRNA ratio was significantly different among these groups (IL-17>PBS>anti-IL-17>normal group). In immunohistochemical stain, RANKL, RANK and OPG-positive cells were expressed at synovium. Conclusion: Synovial RANKL/OPG mRNA ratio was enhanced in CIA, and IL-17 induced higher RANKL/OPG ratio in the synovium of CIA, which was blocked by anti-IL-17 antibody. These results suggest that RANKL/OPG mRNA ratio play an important roles on bone destruction, and IL-17 may be actively involved in bone destruction by enhancing RANKL/OPG ratio in CIA model.
동무(東武)와 노사(蘆沙)의 사상적(思想的) 연계 가능성에 대한 고찰 -이기(理氣)관계를 중심으로-

1. Objectives: This study reviews the general theory on Li-Qi (理-氣) found in Dongmu Lee Jema (東武 李濟馬) and Nosa Gi Jeongjin (蘆沙 奇正鎭)'s works and explores the associations between their philosophical systems. 2. Methods: The main ideas on Predisposition (氣稟論) found in Dongmu's works were explored in connection with the Li-Qi (理-氣) theory and compared with the perspectives suggested by Nosa. 3. Results and Conclusions 1) Nosa criticized the "weakened supervision of Li (理)" and the "separation of Li (理) and Qi (氣)", proposing that this problem can be overcome through "mutual embracement of Li and its manifestations (理分圓融 理分相涵)". 2) When Dongmu's theory on Predisposition (氣稟論) is interpreted in terms of Li-Qi (理-氣), the Seong-Li (laws governing the organ scheme) (性理(臟理)) represents the Li (理) while the formational variations in organ scheme(臟局短長) and and the level of self-cultivation (心地淸濁) represents the Qi (氣). 3) The concept of "Diversification of Li (理之異)", bearing similarities to Nosa's Li-Qi (理-氣) theory, was introduced for the first time in Dongmu's theory on Predisposition (氣稟論), which presumably built the fundamental theories in the Sasang Constitutional Typology. 4) Within Dongmu's theory of Predisposition (氣稟論) can be found a dichotomous division of "similitude between the morally unaccomplished and the morally accomplished" in the ontological plane and "dissimilitude between the morally unaccomplished and the morally accomplished" in the axiological plane; this dichotomy is more extensive and developed compared to Nosa's attempt to find a consistent logic in both the ontological and axiological plane through a Li-Qi (理-氣) structure with Li-predominance.
