A Giant cell tumor of bone has unusual characteristics of pulmonary metastasis as well as local aggressiveness. Clinical courses of pulmonary metastasis of benign giant cell tumor vary including rapid growth, continuously slow growth or spontaneous regression. We report a case of extensive pulmonary metastasis of giant cell tumor of bone, which regressed spontaneouly.

Giant cell reparative granuloma (GCRG) is an uncommon benign lesion that is most commonly found in the mandible and maxialla, and is a very rare condition in finger. We report an unusual case of GCRG arising in the index finger of a 21-year-old man. Histology was characteristic of giant cell reparative granuloma.

Periosteum and periosteum-derived progenitor cells have demonstrated the potential for stimulative applications in repairs of various musculoskeletal tissues. It has been found that the periosteum contains mesenchymal progenitor cells capable of differentiating into either osteoblasts or chondrocytes depending on the culture conditions. Anatomically, the periosteum is a heterogeneous multi-layered membrane, consisting of an inner cambium and an outer fibrous layer. The present study was designed to elucidate the cellular phenotypic characteristics of cambium and fibrous layer cells in vitro, and to assess whether structural integrity of the tendon in the bone tunnel can be improved by periosteal augmentation of the tendon­bone interface. It was found the cells from each layer showed distinct phenotypic characteristics in a primary monolayer culture system. Specifically, the cambium cells demonstrated higher osteogenic characteristics (higher alkaline phosphatase and osteocalcin levels), as compared to the fibrous cells. Also in vivo animal model showed that a periosteal augmentation of a tendon graft could enhance the structural integrity of the tendon-bone interface, when the periosteum is placed between the tendon and bone interface with the cambium layer facing toward the bone. These findings suggest that extra care needs to be taken in order to identify and maintain the intrinsic phenotypes of the heterogeneous cell types within the periosteum. This will improve our understanding of periosteum in applications for musculoskeletal tissue repairs and tissue engineering.

Objective This study was undertaken to determine the effect of Whallak-tang on expression of CD/cytokine Genes. Methods The expression of CD/Cytokine Genes were examined by cDNA microarray using the human mast cell line(HMC-1). Results The expression of ATP5F1, FLJ20671, unknown, KIAA0342, OAS2, unknown genes were increased in $200{\sim}300%$ range. The expression of unknown, MDS006, IFITM1, MRPL3, ZNF207, FTH1, FBP1, NRGN, NR1H2, KIAA0747 genes were decreased in $0{\sim}33%$ range. Conclusion These results would provide important basic data on the possibility of the clinical treatment of Whallak-tang in musculoskeletal disease.

Between Sep. 1986 and Mar. 1996, twenty four patients with recurrent giant cell tumor of their long bones were treated and followed up for more than two years. We applied three different modalities for treatment: curettage with bone graft, curettage and packing with polymethylmethacrylate, wide excision with or without reconstruction. During the average 51.5 months after operation(24-97 months), two of three patients who underwent curettage with bone graft showed recurrence. Patients who underwent wide excision showed no recurrence. Five of fifteen patients who underwent curettage and packing with polymethylmethacrylate showed recurrence. Four of seven who showed recurrence were treated with reapplication of curettage and packing with polymethylmethacrylate. All four patients showed no recurrence, and two of them have been followed up for more than two years. We suggest that the curettage and packing with polymethylmethacrylate is an effective treatment modality of the recurrent giant cell tumor.

Giant cell tumor is usually found around the knee joint, especially in the distal femur or proximal tibia. Despite being classified as benign, it has unusual biological behavior of local aggressiveness and tend to have severely destructive lesion and develop rare pulmonary metastasis. Therefore, when the patient is presented to the physician with an expansile lytic lesion of challenging clinicopathologic entity extending to subchondral bone, the physician faces up to difficulties in treatment. We report a case of 25 years old patient having recurrent giant cell tumor in the right distal femur which developed metastasis to lung. The primary bone lesion was treated with local curettage and fillings with methylmethacrylate, but when he returned to the hospital two years later, the recurrence had developed with lung metastasis.

Giant cell tumor was described by Sir Astley Cooper in 1818. This tumor is considered to be a benign tumor but has problems of recurrence and metastatic change after treatment. Methods of operative treatment of this tumor have included currettage, currettage and bone graft, excision, resection, excision and graft and amputation. We experienced a case of giant cell tumor which involved the distal part of right radius and treated by wide excision and fibular graft. The postoperative courses have been satisfactory because of no recurrence or malignant change. After 6 years and 1 month follow up, the patient was able to return to daily life without any problem.

Extramedullary plasmacytoma is extremely rare, constitute 3 to 5 % of plasma cell malignancies and commonly occur in the upper aerodigestive tract. Several case studies of extramedullary plasmacytoma occurring in unusual location are reported; stomach, bladder, central nervous system, breast, thyroid, testis, salivary gland and skin. Here, we present a case of an extramedullary plasmacytoma of the right gluteus maximus muscle in a 49-year-old man.

Objectives : Juglandis Semen herbal acupuncture solution(JSS) has a broad array of clinical applications in oriental medicine, including treatment of chronic musculoskeletal diseases such as arthritis. This study was performed to investigate the global gene expression profiles using microarray assay in RAW 264.7 cell line treated with JSS and to advance our understanding of the pharmacologic effect of Jss. Methods : Change of the gene expression profile in RAW cell line following treatment with JSS alone, with lipopolysaccharide(LPS) alone, or with LPS plus JSS was investigated with a cut-off level of 2 fold change in the expression. Results : Of the 8170 genes profiled in this study, 95 were upragulated and 42 downregulated following JSS treatment, 51 were upragulated and 21 downregulated following LPS treatment, and 88 were upregulated and 69 downregulated following costimulation of JSS and LPS. Conclusion : JSS treatment induced upregulation of some genes including IL-10 with its possible implication in an antiinflammatory action of JSS. However, further research on expression profile changes induced by JSS treatment is expected.
