We present a case of nevus flammeus associated with angiokeratoma of Fordyce and lymphangioma circumscriptum in a 26 year-old Korean man. We have known that the congenital hemangiomas may be associated with many syndromes such as Kasabacb-Merritt syndrome, Sturge-Weber syndrome and etc. Recently the congenital hemangiomas associated with angiokeratoma or lymphangioma were reported in several literatures, Watson and McCarthy reported that it seemed to be established that three types of benign vascular tumors had a common origin and grew in an identical fashion by projecting buds of endothelial tissue. So the congenital hemangiomas may have a close association with angiokeratoma or lymphangioma.

An giant cell tumor arising from the tendon sheath and other soft tissue of the extremities, hasbeen of clinical and pathologic interst for many years, which is the second most common tumor of the hand, but it is not common in other location. One case of tendon sheath giant cell tumor with regional bone destruction on the pharangeal bone is presented which experienced at Department of Orthopaedic Surgery, Korea University recently. At first, the lesion of bone that is confused with Enchondroma in roentgenographically, which is confirned regional bone destruction of tendon sheath giant cell tumor by histologically. The tumor is composed of a vascularized network of spindle shaped or ovoid stromal cell regularly and rather interspersed with multinuclear cell and xanthoma cells. We report a case of giant cell tumor of tendon sheath and review of literature.

The head-pelvic skeletal traction was first attempted in 1958 by Arther R. Hodgson., and was described. The Halo skull traction apparatus by Perry and Nickel (1959), the method were provided for immobilising the unstable cervical spine, correction of the Scoliotic deformity, Tuberculotic Kyphosis, and other deformed disease. We performed Halo-pelvic apparatus,after posterior-fusion of unstable cervical spine, on a 24 year old male, with Quadriplesia due to Fracture-dislocation of the 7th cervical spine in May 1976. The following were the condition to be met: 1) Rigid stabilization and improved the cervical pain. 2) progressive adjustable., longitudinal traction for reduction 3) The patient was able to sitting position withont other Supports. 4) No pressure sores developed as happens beneath a cast. 5) Ease of patient management and taking of Roentogenogram.

We have used BALB/c mice as an animal model for the study of anaphylactic hypersensitivity to the house dust mite. For the sensitization, BALB/c mice were injected with a single dose of extracts of Oermatophagoides farinae (D. pa) or Dermatophagoides pteronyssinus (D. pt) mixed with adjuvants (aluminum hydroxide and Bordetella pertussis) intraperitonealy. On days of 15, 30, and 60 after the sensitization, the mice received a challenge dose of the same allergen intravenously to induce anaphylactic shock. The hypersensitivity reactions were scored by anaphylactic shock. And various immunological parameters, including cytokines and immunoglobulin isotypes, were studied in relation with the shock. A high level of anaphylactic shock was produced in the mice by both of the allergens, D, fa and D, pt, at 15 and 30 days after sensitization. In vitro Ag specific proliferative reponses of spleen cells from D. pt treated mice (D. pt mice) was six times higher than those from O. fa treated mice (O. fa mice). Regardless the differences in antigens, the production of IFN-r by spleen cells from D. pt mice or O. fa mice was equally high at 15 days after sensitization. However, the ability to produce IFN-r by the spleen cells from D, pt mice was three times higher compared to that from D. fa mice. The production of IL-4 by the spleen cells was enhanced slightly but not significant in both groups. In studies of the allergen-specific immunoglobulin isotypes in the sera of the mice, the level of IgE in both groups was enhanced slightly but not significant. In contrast, the level of IgG subtypes were increased in both groups. When the levels of IgG were compared by subtypes, the level of IgG1 increased significantly on day 15 when the anaphylactic shock score was maximized in both groups. Increase in IgG2a level at the day was not significant, instead, asignificant increase in IgG2 levels was observed on day 60 after sensitization when the anaphylaxis was almost discontinued. Although a higher level of IgG3 was examined on day 15 and 30 in D. pt mice and on day 60 in D, fa mice, anaphylaxis was not appeared to be associated with the levels of IgG3 in this study. The IgG1, rather than IgE, was assumed to the major factor involved in the anaphylactic response observed in this experiment. In conclusion, BALB/c mice would be an animal model for the study of anaphylactic hypersensitivity to D. fa or D, pt., which might be an essential tool for the future development of immuno-therapeutic agents.

Peripheral nerve injury is relatively common in post-trauma surgery. Although various microsurgical techniques and repair methods can recover the continuity of the injurcd nerve. But, functional recovery achive is difficult. The purpose of this study examines the effect of electrical stimulation on muscle strength or sensibility increase in hrachial plexus injury with clinical results. We have retrospectively analyzed 44 cases of brachial plexus injury. The group(20 cases) which received nerve surgery and electrical stimulation was compared with the group(24 cases) which received nerve surgery only. Electrical stimulation was performed to nerve for axonal regeneration-strength & sensibility(18 cases) and to muscle for strengh(2 cases). All cases had heen evaluated for motor power recovery by 24 months after nerve surgery. A significant difference(P<0.05) between the power of elhow flexion and shoulder abduction, hut not sensibility of forearm in the two groups suggests that electrical stimulation to nerve or muscle enhanced the progress of nerve regeneration or muscle strength respectively. The results suggest that electricai stimulation is promising supplementary method for functional recovery in brachial plexus injury.

The purpose of this study is to evaluate the short-term results of the reconstruction of acetabular bone defect radiographically. Twenty three reconstruction with bone graft and non-cemented porous hemispherical cup and one reconstruction with bone graft and cemented polyethylene cup that had been performed in 24 patients from 1991 at Wonkwang University Hospital and had followed more than one year were included in this study. Osseous union, resorption of the graft, the amount of the migration and angle change of the acetabular components and radiolucency were checked on plain X-ray. 9 morselized grafts for contained defect showed 100% union within 6 months, without severe resorption and loosening. Of the 15 structural grafts, 11 minor column or shelf grafts showed 100% union and remodeling, and one case of radiolucency around the cup. There were two collapses of the structural graft and one migration of the cup which suggest the failure among the 4 major column grafts. For the above 3 failed cases, non-cemented porous hemispherical cups were used. In conclusion, bone graft for reconstruction of the deficient acetabular bone stock seems to be suc- cessful, but the use of cement and the delay of weight bearing should be considered for the major column graft.
