Parameters of the left ventricular performance were evaluated by echocardiographic examination in 66 normal subjects. Effects of pulse rate, systemic arterial pressure, peripheral resistance and left ventricular end-diastolic dimension on the parameters were also observed. Normal value(mean+/-SD) of fractional shortening was 34.0+/-5.2%, ejection fraction 0.71+/-0.07, mean rate of circumferential fiber shortening 1.15+/-0.19 circ/sec, mean posterior wall velocity 4.05+/-0.70cm/sec, maximal posterior wall velocity 6.31+/-1.26cm/sec, mean normalized posterior wall velocity 0.82+/-0.14/sec, and maximal normalized posterior wall velocity 1.28+/-0.24/sec. There were negative correlations of peripheral resistance to fractional shortening, ejection fraction and mean rate of circumferential fiber shortening. Pulse rate and left ventricular end-diastolic dimension did not have significant effects on these parameters. Mean and maximal posterior wall velocity had negative correlations to peripheral resistance and positive correlations to left ventricular end-diastolic dimension. But mean and maximal normalized posterior wall velocity had no correlations to any of them.

BACKGROUND: The majority of Staphylococcus aureus strains isolated from atopic eczema skin produce toxins like enterotoxin B or toxic shock syndrome toxin-1(TSST-1) as a superantigen and these toxins may contribute to the exacerbation of this skin disease. OBJECTIVE: We designed this study in order to investigate the effect of toxic shock syndrome toxin-1 on IL-4, interleukin-10(IL-10), interleukin-12(IL-12) and IFN- r production by peripheral blood mononuclear cells from normal and atopic patients. METHODS: Peripheral mononuclear cells obtained from ten patients with severe atopic dermatitis and ten healthy volunteers were stimulated with TSST-1 and cultured for 4 days. The amount of IL-4, IL-10, IL-12 and IFN- r in the culture supernatants were determined by a solid-phase enzyme- linked immunosorbant assay. RESULTS: l. After stimulation with TSST-1, IL-4, IL-10, IL-12 and INF- r, production of peripheral mononuclear cells from both atopic patients and healthy volunteers were increased. 2. After stimulation with TSST-1, the amount of IFN- r in the culture supernatants was significantly greater in the healthy controls than in the atopic patients. 3. After stimulation with TSST-1, the amount of IL-10 in the culture supernatants was significantly greater in the healthy controls than in the atopic patients. CONCLUSION: This data indicates that TSST-1 induces Thl-type and Th2-type cytokines associated with parallel Thl and Th2 stimulation in atopic patients and healthy donors. In addition, peripheral mononuclear cells from atopic patients have a diminished capacity to synthesize IFN- r and IL-10 in vitro in response to stimulation with TSST-1. Our results suggest that TSST-1 is not considered as a really important aggravating factor in atopic dermatitis.

Osteoporosis has recently been recognized as a major health problem in the elderly population. The disorder is manifested as a loss of bone mass accompanied by structural alteration of bone and increased incidence of fracture. Mandible also may be affected. So, I evaluated panoramic views of 66 postmenopausal women for finding the possibility of useful diagnostic mandibular parmeters of osteoporosis. To know the correlationship between skeleton and mandible, the average of the bone mineral density of lumbar from 2nd to 4th by the dual energy X-ray absorptiometry(DEXA, LUNAR DPZ. USA), and age and mandibular parameters, that is, the number of residual teeth, alveolar ridge resorption ratio, panoramic mandibular index (PMI), mandibular cortical width (MCW), angular cortical thickness (ACT), ramus cortical thickness (RCT), morphology of mandibular inferior cortical (MIC) were compared. And I divided the all tested women to the osteoporotic group and non-osteoporotic group by the use of T-score-2.0, which was derived from skeletal bone mineral density (BMD). To find the correlationship of the each group with mandibular parameters, t-test and discriminant analysis were done. The results of the t-test were that all parameters were highly related with 2 groups (p<0.05). Especially ACT, MIC, age have had even higher correlationship than others (p<0.001). The results of the discriminant analysis by the use of these ACT, MIC and age were that the discriminant function was Z =-2.973+(-1.447)x(ACT)+1.131x(MIC score)+(0.052)x(age), the cutting score was 0.257 and the classification accuracy was 84.8%. Therefore I suggest that the consideration of the angular cortical thickness (ACT), the age of patient and the morphology of mandibular inferior cortical(MIC) may help find the osteoporosis.

Purpose: Dislocation is the second most common cause of failure, after implant loosening, in revisional THA (Total hip arthroplasty), and its evaluation and treatment still remain controversial issue. This study was undertaken to evaluate the risk factors after THA using the posterolateral approach and posterior soft tissue repair. Materials and Methods: Between January 1998 and May 2003, 211 consecutive primary total hip replacement arthroplasties using the posterolateral approach and posterior soft tissue repair were performed by the same surgeon. To compare the dislocation groups (6 cases) with the non-dislocation groups (205 cases), we randomized 120 of the non-dislocation cases. The risk factors for hip dislocation were categorized into patient factors and surgical factors. Patient factors included gender, age, preoperative diagnosis, underlying systemic disease, and alcoholic history. Surgical factors included position of the component (acetabular version and inclination, femoral anteversion), leg length discrepancy, and sum of anteversions of the cup and stem. Their parameters were measured on postoperative radiographs. Statistics were performed with Fishe`s Exact test and T test. Results: Dislocations occurred at an overall incidence rate of 2.8% (6/211cases). There were 4 (1.9%) cases of anterior dislocations and 2 (0.9%) cases of posterior dislocations. Dislocations occurred on average at postoperative day 6.1 and all dislocated hips were reduced with the closed method, except for one case that was treated surgically. There was no statistical significance in patient factors between the two groups, except for neurologic disease and alcoholic history. However, the sum of the acetabular and femoral anteversions in the anterior dislocation group was larger than that of the non-dislocation group by approximately 19 degrees. Conclusion: Our results demonstrated that by using the posterior approach and repair of soft tissue, the posterior dislocation rate after total hip replacement arthroplasty can be reduced and the sum of the acetabular and femoral anteversions had more influence on dislocations after THAs than did either anteversion alone.

To build and to manipulate clinical data in one of the important works in the hospital. In order to accurately append the data and to quickly find and display the informations as the user need, we developed a software program running on the personal computer. Our system largely consists of four parts; registration of the clinical and departmental data, retrieving tool of articles in the medical journal, collection of special data for clinical survey and display system of the various reports. In our experiences, we consider the key factors for systemic management of clinical rearch data base as the follows; work analysis for data processing, design of data base, coding and classification of basic data and technique of registeration. Of these standarized coding system of the orthopedic diseases appeare to be of it most importance.

An irreducible atlanto-axial rotatory dislocation(so-called fixation) is an extremely rare deformity. Its stricking features are the delay in diagnosis and the persistent clinical and roentgenographic deformities. The diagnosis is suggested by the plain roentgenograms and is confirmed by operation. A 9 year-old boy having the atlanto-axial rotatory fixation was examined at Pohang St. Mary's Hospital in July 1985 and was treated with skull traction followed by Gallie fusion. He was followed up over a year, and had satisfactory result at last follow-up.
