  • 사람 무릎관절의 윤활막을 대상으로 정상과 퇴행성관절염 시의 윤활막의 변화와 tenascin의 발현을 면역전자현미경적 방법으로 비교, 관찰한 결과 다음과 같은 결과를 얻을 수 있었다. 1. 정상의 윤활막과 비교하여 퇴행성관절염 시에 윤활막이 두터워지는 것은 주로 윤활분비세포의 수적인 증가에 의한 것임을 알 수 있었다. 2. Tenascin에 대한 면역금의 관찰 결과 정상의 윤활막을 구성하는 세포에서는 면역금의 표지가 관찰되지 않았다. 3. 퇴행성관절염 시 윤활막의 윤활분비세포 과립세포질 세망에서 면역금의 표지가 관찰되어 tenascin의 분비세포가 윤활분비세포임을 확인할 수 있으며, 윤활세포 사이의 바탕질의 아교섬유에서도 tenascin의 표지가 관찰되었다. 이상의 결과를 종합해 보면, 퇴행성관절염 시에 윤활막이 두터워지는 것과 병변의 진행과정에, 윤활분비세포의 수가 증가와 tenascin의 발현 증가가 관련성이 있는 것으로 생각된다.

  • Objectives Trachelospermi caulis, known as Nak-Suk-Deung in Korea, is the dried leafy stem of Trachelospermum asiaticum var. intermedium Nakai, and climbing stems and branches of Trachelospermum sdisyivum var, intermedium nakai or Apocyanaceae. Trachelospermi caulis has antipyretic and analgesic activity. It has traditionally been used as a folk remedy in Korea for the treatment of various infla mMatory diseases, including rheumatoid arthritis. The purpose of this study was to evaluate the Effects of Trachelospermum caulis extract on SNP-induced infla mMatory responses in rabbit HIG-82 synovial membrane cells. Methods Anti-infla mMatory effects of the extract of Trachelospermum caulis were investigated using rabbit HIG-82 synovial membrane cells. For this study, 3-(4,5-dimethylthiazol- 2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, western blot analysis, PGE2 i mMunoassay, and NO detection were conducted. Results The aqueous extract of Trachelospermum caulis exerted cytotoxicity and suppressed PGE2 synthesis and NO production in rabbit HIG-82 synovial membrane cells. The aqueous extract of Trachelospermum caulis also inhibited the SNP-induced expressions of COX-2, iNOS, and TNF-$\alpha$ in rabbit HIG-82 synovial membrane cells. Conclusions These results showed that the extract of Trachelospermum caulis exerts the anti-infla mMatory effect by suppressing COX-2, iNOS, and TNF-$\alpha$ expressions in the synovial membrane cells.

  • 악관절부위의 활액성 연골종증은 매우 드물기 때문에 확진하기 까지 종종 몇 개월 몇 년이 걸리도 한다. 활액성 연골종증은 드문 양성 병소로 활액 내 수 많은 연골성, 골연골성 결정과 관절강내의 소성체가 형성되는 질환으로 관절강 내에 소성체를 형성하는 활액막의 연골성 변성으로 정의할 수 있다. 본 증례에서 29세 여자 환자로 저작시 동통을 주소로 내원하였다. 방사선 소견상 상관절강내에 석회화된 소성체가 발견이 되었다 치료는 석회된 소성체와 활액막 일부를 제거하였다. 술 후에 환자의 저작시의 동통이 완전히 사라졌다. 현재 아무런 재발 증상을 보이지 않고 있다.

  • The development of synovial membrane from knee joint was studied by electron microscope in human fetuses ranging from 20mm to 260mm crown rump length (40days to 30weeks of gestational age). At 40mm fetus, developing synovial tissue was observed in homogenous interzone as a vascular mesenchyme around the periphery. The primitive joint space was appeared after the intermediate layer of the interzone in direct contact with chondrogenic layer at 60mm fetus. Differentiation of the synovial membrane coincided with clarification of the joint cauity. When dilatation of the synovial cavity occurred, the two types of synovial cells were well endowed with rough endoplasmic reticulum. At 100mm fetus, type A cells with a markedly attenuated cytoplasm were found as well as those cells which contained pinocytotic vesicles and vacuoles. By 150-200mm fetuses a majority of the intimal cells were type B. These cells were characterized by abundant rough endoplasmic reticulum and well developed Golgi complex. In contrast, A-type cell had numerous filopodia, pinocytotic vesicles lysosomes, and large vacuoles containing amorphous material. At 260mm fetus, the intimal cells were well developed and plentiful. The most marked difference between the synovial membrane of full-term fetus and adult was the large amount of collagen in the latter. During fetal period, the B-cells were most numerous cell type in the intimal cells. The B-cells were clearly distinguishable from the A-cells by their content of extensive rough endoplasmic reticulum and well developed Golgi complex.

  • Rheumatoid arthritis (RA) is one of the most typical rheumatic diseases, and is characterized by chronic inflammation, cartilage destruction and joint deformity [1,2]. During this process, profound hypertrophic changes of the synovium with infiltration of immune cells, increased vascularity, and hyperplasia result in the formation of a synovial pannus that invades cartilage and bone [3]. In early stages of RA, the synovial membrane begins to invade the cartilage. In established RA, the synovial membrane becomes transformed into inflammatory tissue, the pannus (Fig. 1). The cell types that occupy cartilage-pannus junctions include synovial macrophages, fibroblasts, mast cells, polymorphonuclear lymphocytes (PMNs), and displaced, probably differentiated condrocytes [4-6]. Recent studies of rheumatoid synovial tissue have demonstrated localized accumulations of mast cells and evidence of their activation/degranulation[7].

  • To investigate the morphology of the synovial lining cells, synovitis was induced by carrageenin injection into the rat knee joint cavities. Synovial membranes were excised at 1, 3, 5, 7 and 14 days, and histologic, electron microscopic, histochemical (periodic acid Schiff: PAS, toluidine blue), and enzyme histochemical (acid phosphatase: ACP, nonspecific esterase: NSE and endogenous peroxidase) studies were performed. The results are as follows: Carrageenin induced synovial membrane hypertrophy with synovial cell proliferation and granuloma formation. The proliferated synovial lining cells and macrophages in the granulomatous lesion had round to oval nuclei and large, plump cytoplasm with many phagocytotic materials and vacuoles. Electron microscopically, these cells had small number of granular endoplasmic reticulum and many lysosomes, phagosomes and vaculoes. Mitotic figures were observed at early stage of experiment. PAS and toluidine blue stains showed strongly positive reaction in the cytoplasm of the proliferated lining cells and macrophages in granulomatous lesion. ACP and NSE activities were strong positive in the cytoplasm of the proliferated synovial lining cells and macrophages in the granulomatous lesion. But endogenous peroxidase stains were negative in all prolifeative lining cells and macrophages in granulomatous lesion. Conclusively, carrageenin-induced synovitis showed proliferation of synovial lining cells and granuloma formation in deep layer. The macrophages, which consisted of the lesions and have active phagocytic function, were speculated to proliferate by mitosis of superficial synovial A cells and histiocytes in the deep layer of the synovial membrane.

  • Synovial chondromatosis is an uncommon disorder characterized by cartilaginous proliferation in the synovium. The cartilaginous nodules occur in the synovial membrane of a joint, bursa, or tendon sheath. It frequents large joints including knee, hip, and elbow. Synovial chondromatosis originating from the first metatarsal is extremely rare. We report a case of 37-year-old man with synovial chondromatosis of the first metatarsal.

  • Synovial chondromatosis is the chondroid metaplasia of the synovial membrane, Large joints such as the knee and hip are commonly involved. Synovial chondromatosis very rarely develops within the shoulder joints. We have experienced the synovial chondromatosis developed in the right subscapular recess communicating the shoulder joint of a 30 year-old-female who was diagnosed by plain radiograph, MRI and microscopic findings, and then treated by arthroscopic synovectomy and removal of loose bodies.

  • Osteochondroma is a benign lesion of osseous and cartilagenous origin. It is a relatively common benign tumor of the skeleton, occurring most often in the metaphyseal region of long bone. However, it is rare in the facial bones. Reported foci in the mandible were the condyle, coronoid process, and symphysis region. Synovial chondromatosis is an uncommon benign condition of unknown etiology which affects the articular joints. Foci of cartilage develop through metaplasia in the underlying connective tissue of the synovial membrane. These cartilagenous foci and fragments may undergo calcification and ossification. We experienced 4 patients with abnormal appearance of mandibular condyle. This report describes 3 cases of osteocondroma and 1 case of synovial chondromatosis of the mandibular condyle with review of the literature.
