The purpose of this article was to identify trend in Arthritis research and to provide ba an approach of Arthritis research. The results of analysis of 69 Arthritis articles public year of between 1970-1999 found that most articles(27.6%, n=19) were published since few(10.1%, n=7) were before 1994. Vast majority of articles(79.8%, n=55) were printed in The Journal of Rheumatology Health, and 79.8%(n=55) of those were quantitative research, 8.7%(n=6) were qualitative research, and 14%(n=1) was methodological research. 29.0%(n=20) of quantitative research were carried in experimental design and over half(50.8%, n=35) in nonexperimental design. Having concerned the types of treatment(or intervention) used in experimental study, the most common treatment was 'exercise' (45.0%, n=9), and other less common were 'self-help education(15.0%, n=3), home care(10.0%, n=2) supportive care(10.0%, n=2), flexibility exercise combined with local heat therapy(5.0%, n=1), relaxation training(5.0%, n=1). Of the types of exercise, aquatic exercise was 30.0%(n=6). The effect of exercise on outcome variable was found to be most strong among the other types of treatment. 18 articles of nonexperimental research were correlational research. From the analysis of correlational research, 29 concepts were identified, and the relationship between depression and other variable were strongly reported. In descriptive studies, most commonly physiological variables were examined in 5 articles(29.5%). Only one study(5.9%) explored patient's perception of the causal factors and those causality. In qualitative researches, two study were carried out by the means of grounded theory. Majority of those subjects were RA patients, and the largest number of sample were 23 and the smallest was 1 In two studies, patient's perceived causality of RA was identified as a research problems, and an experience of ADL, fatigue Phenomenon, an experience of having a total knee replacement with osteoarthritis were each found in one study. Methodological research was carried out to test validity and reliability of the RA Fatigue Scale.

A biomechanical study was made to demonstrate the superior mechanical performance of the newly designed Miniplate staple to the conventional Coventry staple in high tibial osteotomy(HTO). Using twenty fresh porcine tibiae, the fixational strengh of the two different types of staple in HTO was compared. To minimize the error due to the specimen-to-specimen individuality, the bone mineral density of the tibiae was measured with a bone densitometry (Dual photon absorptionometer, Luner, USA) and those with $0.8\;{\sim}\;1.2\;gm/cm^2$ at the proximal tibia was used in the biomechanical test. Testing was performed on a material testing system (Autogram ET-5, Shimatzu, Japan) with aid of a commercial data processor (IBM 80386/ ASYST). Using two differant loading modes, 'pull-out' and 'push-out', the maximum resistant force required to release the staple from the substrate bone was recorded. In the pull-out test, ten non-osteotomized specimens were used and the staple was pullout by subjecting an axial tension on the head of the staple inserted. While in the pull-out test where ten tibiae osteotomized in the usual way of HTO were used, the staple was not directly loaded. In this testing, as a mimic condition of the natural knee, the distal part of the specimen tibia was pushed horizontally in order for the staple to be pulled out while the proximal tibia was fixed. The pull-out strength of Coventry staple and miniplate staple were found to be $27.88\;{\pm}\;5.12\;kgf$ and $182.47\;{\pm}\;32.75\;kgf$, respectively. The push-out strength of Coventry staple and miniplate staple were $18.40\;{\pm}\;4.47\;kgf$ and $119.95\;{\pm}\;19.06\;kgf$, respectively. The result revealed that miniplate staple had the pull-out/ push-out strength at least fivetimes higher than Coventry staple. Based on the measured data, it was believed that the newly designed miniplate staple could provide much better postoperative fixation in HTO. The postoerative application of long leg casting may not be needed after HTO surgery.

증식치료는 정상세포나 조직을 성장시키기 위해 성장인자 또는 성장인자 생성 자극제를 주사하는 것이다. 비록 수십 년 동안 논쟁이 되어 오고 있지만 갈수록 더 많은 의사들이 증식치료를 시술하고 있다. 증식치료라는 단어는 1950년 대에 Hacket에 의해 기술되었는데 인대나 근건에 있는 정상조직의 증식을 의미 하였다. 인대 염좌 등의 불완전한 치료는 만성 통증뿐만 아니라 관절불안 등을 초래하고 골관절염의 진행을 촉진할 수 있다. 증식치료는 통상적인 치료에 불응하는 이러한 근골격계 질환에 사용된다. 사용되는 증식제나 수기는 의사마다 수련과정 또는 선호도에 따라 차이가 있을 수 있지만 최근 가장 많이 사용되는 증식제는 10~25%의 포도당이다. 고해상도 초음파기기의 발전에 따라 인대나 근건 등을 실시간으로 볼 수 있게 됨에 따라 이를 증식치료에 접목하여 수기의 정밀도를 높이고 주입되는 약의 확산을 확인 할 수 있게 되었고 그 치료 결과를 기록할 수 있게 되었다.

In this study, we compared the immune cell populations in rheumatoid arthritis (RA) synovial fluid, which shows lymphoid tissue-like structure, with those in tonsils, which are normal secondary lymphoid tissues. Firstly, we found that $CD4^-CD11b^+$ macrophages were the major population in RA synovial fluid and that B cells were the major population in tonsils. In addition, synovial fluid from patients with osteoarthritis, which is a degenerative joint disease, contained $CD4^+CD11b^+$monocytes as the major immune cell population. Secondly, we categorized three groups based on the proportion of macrophages found in RA synovial fluid: (1) the macrophage-high group, which contained more than 80% macrophages; (2) the macrophage-intermediate group, which contained between 40% and 80% macrophages; and (3) the macrophage-low group, which contained less than 40% macrophages. In the macrophage-low group, more lymphoid tissue inducer (LTi)-like cells were detected, and the expression of OX40L and TRANCE in these cells was higher than that in the other groups. In addition, in this group, the suppressive function of regulatory T cells was downregulated. Finally, CXCL13 expression was higher in RA synovial fluid than in tonsils, but CCL21 expression was comparable in synovial fluid from all groups and in tonsils. These data demonstrate that increased lymphocyte infiltration in RA synovial fluid is correlated with an increase in LTi-like cells and the elevation of the chemokine expression.

Opening wedge high tibial osteotomy (OWHTO) is widely used to treat unicompartmental osteoarthritis of the knee caused by degenerative deformations of the anatomical axes of the leg. However, since it is difficult to accurately plan the surgical degrees of adjustment such as coronal correction angle and tibial posterior slope angle to align the axes before the actual procedure, a number of studies have proposed analytical models to solve this problem. While previous analytical models for OWHTO were limited to specific cases, this study proposes an analytical osteotomy model (AOM) and a surgical planning system (SPS) that are suitable for a wide range of tibial morphologies and tibia conditions. The validity and generality of the model were verified in a total of 60 OWHTO cases. Results of the test showed that, as predicted, surgical degrees are affected quite significantly by tibia shape and slope of the resected surface. Comparison of the required surgical degrees and the degrees estimated from virtual surgery simulations using AOM showed a very small average difference of $0.118^{\circ}$. SPS, based on AOM, allows the operating surgeon to easily calculate surgical parameters needed to treat a patient.

This study investigated cases of progressively necrotizing limbs in Korean indigenous calves. The recent case (Case 1) involved a 3-month old, male calf in Jeonbuk province that presented a visibly dry form of gangrene affecting joints of the forelimbs and the hind limbs. Radiograph revealed osteoarthritis possibly resulting from pressure of disrupted joint skin, fasciae, deeper underlying musculatures and tendon. Histopathology of affected tissue showed necrotizing; severely thrombosed dilated blood vessels with rechanneling microvasculatures. The lack of substantial infectious inflammatory exudates in the vital organs and the inability to respond to antimicrobial treatment bolstered the notion that the observed thromboembolic and vascular lesion was attributed to possible vasoconstrictive effects of ergot alkaloids. Case 2: A previously encountered similar case in a 4-month old, male calf showing gangrene of hind limbs and posterior ataxia was likewise presented. These two cases were impressed as probable ergotism. Ergotism may be uncommon or underreported in Korea. Future isolation of ergot alkaloids in feeds or in pasture is highly suggested.

Background: The purpose of this study was to investigate the effect of structured cryotherapy on edema of patients who had a total knee arthroplasty (TKA). Methods: The subjects were 58 patients who were diagnosed with osteoarthritis and had total knee arthroplasty in D hospital. In total, 29 people were in the leg elevation cryotherapy group (LECTG), 29 people were in the control group (CTG). After TKA, the patients' swelling on post operation days (POD) 3 were checked. After the post OP checking, LECTG was treated with cryotherapy with leg elevation for 12 days but CTG was cryo therapy with sit on chair. Results: Swelling show significant difference within the group (p<.05), but did not show signigicant difference between groups (p>.05). Conclusions: Base on the results, it was found the cryo therapy of $-78^{\circ}C$ improved swelling after TKA. Accordingly, it is thought that cryo therapy of $-78^{\circ}C$ has positive effect on swelling in the process of recovery after operation. but It did not approve that the leg elevation was even more effective. For this study, the reserch developed to enhance the effectiveness of the cryotherapy, would make it possible to apply to an effective cryotherapy posture.

Objectives This study was aimed to evaluate the effects of Daeyoungjeon (hereinafter referred to DYJ) treatment on the injury of articular cartilage induced by monosodium iodoacetate in rats. Methods Twenty-four male rats were divided into normal, osteoarthritic control and DYJ group. Rats of normal group were injected with 0.1 ml physiological saline, rats of control and DYJ groups were injected with 0.1 ml monosodium iodoacetate (3 mg/ml) into each left and right knee joint cavities. Rats of DYJ group were administrated extracts of DYJ during 60 days per orally. At 60 days after treatment, gross lesions, area and proteoglycan contents of articular cartilage, histopathological lesions, immunohistochemistry on matrix metalloproteinases (MMP-2, MMP-3, MMP-7) were evaluated. Results Grossly, degenerative changes of articular cartilages were observed weak in DYJ group. The areas of articular cartilages were broader significantly in DYJ group. The proteoglycan contents in articular cartilages were lesser significantly in DYJ group. Histopathologically, the chondrocyte score was lesser significantly in DYJ group. MMP-3 expression in articular cartilages was observed weak in DYJ group. Conclusions From above results, DYJ treatment has inhibitory effects on the injuries of articular cartilage induced by monosodium iodoacetate in rats, and it's effects may be related with down regulation of MMP-3.
