Gorham's syndrome (Gorham's disease, Massive osteolysis, Disappearing bone disease, phantom bone) is a rare disorder characterized by histologically benign proliferation of thin-walled vascular channels originating in bone associated with extensive lysis of regional bone matrix. It starts in bone, but it may secondarily involve soft tissues and adjacent bones. Although the osteolysis usually arrests spontaneously, its biologic behavior is unpredictable. The etiolgy is still in dispute and the treatment presents many problems. The author's case was a 20-year old girl, who had pathologic fracture in neck and supracondylar area of left femur with osteolysis of left pelvis, femur, and proximal fibula and tibia. She also had lymphangioma involving bones and adjacent soft tissues. To our knowledge, there is no report on Gorham's syndrome in Korea. The authors report a case of Gorham's syndrome with review of literatures.

STUDY DESIGN: External linkage type of spine motion analyzer and special programs for calculation of the relative angular motion and graphical display were developed and used to measure relative thoracic and lumbar motion patterns in healthy subjects. OBJECTIVES: To examine the dynamic relationship of thoracic and lumbar spines during various trunk motions and to measure main and coupling motions in three-dimensional spinal kinematics. SUMMARY OF LITERATURE REVIEW: Many kinds of methods, such as inclinometer, stereoradiography, electrogoniometer, cadaveric study etc., were introduced for measuring lumbar spine motion. But, there is no reliable method for measuring accurate dynamic three-dimensional motion patterns of whole thoracic and lumbar spines. MATERIALS AND METHODS: Thirty healthy men, ranging in age from 21 to 29 years, participated in the study. The developed device was tested to measure spine motion patterns in flexion, extension, lateral bending and axial rotation. RESULTS: The average range of motion for flexion was 71.30degrees/16.54degrees(lumbar/thoracic), for exten-zion 25.11degrees/12.67degrees, for one side lateral bending 27.42degrees/31.71degrees, for one side axial rotation 30.86degrees/24.38degrees. There were more coupling motions in lateral bending and axial rotation than in flexion and extension. Coupling motion pattern were found to be relatively consistent among subjects in active axial rotation, and the direction of coupling motion was flexion plus ipsilateral side bending. CONCLUSIONS: It was rather simple and reliable method thor spine motion analysis. There were similarities between motion patterns of lumbar and thoracic spine. But, range of motion in sagittal plane was much greater in lumbar spine than in thoracic

The biomechanical responses, such as nucleus pulposus pressure, facet contact force, stress distribution among ligaments in the cervical spine under static loading like flexion and extension, were examined with 3-D nonlinear finite element model. Finite element model consisted of whole cervical spines with intact discs and ligaments was developed from 1mm thick CT-cross sections of a 25-year-old healthy young man. Geometrical nonlinearity was considered for the large deformation and ABAQUS package was used for calculation. Results were verified comparing with those of existing in vivo and in vitro experiments. Results indicated that, developed cervical spine FEM was well consistent with other experiments. Nucleus pulposus pressure increased in flexion and extension more in lower cervical region. Facet contact force increased more in lower cervical spine in extension. In addition, capsular ligament was the most important one among 7 cervical ligaments surrounding cervical spine both in flexion and extension. We could better understand the biomechanics of whole cervical spine with developed finite element model and it might be applied to dynamic or postoperative study.

Many kinds of lumbar diseases cause lumbar segmental instability and/or limitation of motion. But, there is no reliable method for measuring accurate trunk motion. In order to measure relative trunk motion respect to the pelvis in vitro, external linkage type of spine motion analyzer was developed. Special programs for calculation of the relative angular motion and graphical display were also developed. The developed device was tested to compare spine motion pattern between 15 normal volunteers and 18 lumbar fusion patients in flexion, extension, lateral bending and axial rotation. It was rather simple and reliable method for spine motion analysis. And it was possible to measure not only angular displacement but also angular velocity and angular acceleration. There were more coupling motions in lateral bending and axial rotation than in flexion and extension. Compared to the normal subjects, patients showed different angular motion, especially in the angular acceleration. Optimal trajectory of the trunk motion derived from mathematical model in flexion and extension matched well with measurement for normal subjects.

Among the four-hundred patients with cerebral aneurysms confirmed by cerebral angiography, we divided them into two age groups, one with ages 39 years or younger(young-aged group: 51 patients, 12.8%), and another with ages 65 years or older(old aged group: 45 patients, 11.3%). A comparison was undertaken in regard to clinical characteristics and overall outcome in two groups. In young-aged group, the female-to-male ratio was 2.2: 1 whereas, women was predominant by five times more in old aged group. Anterior communicating artery aneurysm was the most common site(43.1%) in young-aged group, unlike to old aged group where posterior communicating artery was the most common site(33.3%). The most common symptom was headache in both groups, and the hypertension was more frequent in young-aged group(45.5%) than old-aged group(33.3%). Surgery was performed in 43 patients(84%) in younger group, and 37 patients(82.2%) in elderly group. Young-aged group showed more favorable outcome(91%) than old-aged group(70%).

OBJECTIVE: Currently available therapies for human malignant gliomas have limited efficacy. Toxoplasma gondii, an obligate intracellular protozoan parasite, and Quil-A are nonspecific, potent immune stimulants. T. gondii is shown to have antitumor activity in some types of cancers. Therefore, this study is undertaken to evaluate the antitumor effect of Toxoplasma lysate antigen (TLA), alone or in combination with Quil-A, on human glioma U373MG and U87MG cells. METHODS: The in vitro effects of TLA alone or in combination with Quil-A on the proliferation, invasion, and apoptosis of glioma cells were tested using MTT, Matrigel invasion, and DNA fragmentation assays, and the in vivo effects on the growth of gliomas were evaluated in athymic nude mice transplanted with glioma cells. RESULTS: Treatment with TLA resulted in the suppressed proliferation and invasion of both U373MG and U87MG cells, in a dose-dependent manner. In addition, at high concentration, TLA induced glioma cell apoptosis. When TLA was administered in the mouse glioma model, malignant glioma growth was decreased. The combined treatment of TLA with Quil-A significantly inhibited the proliferation and invasion of cultured cells as well as tumor mass of implanted mice. CONCLUSION: TLA inhibits the proliferation and invasion of glioma cells in vitro and in vivo, and these antitumor effects of TLA are significantly enhanced by the addition of Quil-A.
