PURPOSE: To determine the necessity of site-specific bone mineral density(BMD) measurement and the difference between the BMD of the two femora using DXA in the evaluation of osteoporosis. MATERIALS & METHODS: Total BMD and regional BMD(Lumbar spine, femoral neck, Ward's area, intertrochanter area) were measured on seventy-eight healthy persons without previons diseases, and the statistical significance analyzed. RESULTS: Total BMD did not reliably reflect the site-specific BMD. There was a high correlation between BMD in opposing femora. Correlation coefficients between the femoral neck, Ward's area, trochanter area were 0. 939, 0.874 and 0.916 respectively. CONCLUSION: We conclude that a measuremnt of site-specific BMD is necessory because the total BMD can not reliably predict the regional BMD. The measurement of BMD in one femur can predict the BMD of the contralateral femur. If there is no history of femoral neck disease, unilateral BMD measurement is recommended for femoral evaluation.

BACKGROUND/PURPOSE: Phospholipase A (PLAq) is an rate-limiting enzyme hydrolyzing arachidonic acid from the sn-2 position of membrane phospholipids. In vitro studies demonstrated that the enzyme could be secreted into extracellular mileu by pro-inflammatory cytokines and endotoxin which were reported to have important roles in chronic liver diseases. This study was performed to know whether the enzyme is involved in the pathophysiology of the diseases. METHODS: The subjects were composed of 24 patients with chronic hepatitis B, 26 patients with liver cirrhosis and 14 healthy individuals. The PLAp activities wem measured in the sera of the subjects by detecting radioactivity of "C-fatty acid hydrolyzed from "C-labeled phosphotadylethanolamine by the enzyme. RESULTS: The activities of PLA were increased in the patients with chronic liver diseases, especially in the chronic hepatitis B patients with acute exacerbation and in the decompensated cirrhosis patients. Furthermore, their activities were closely related with the levels of transaminase in hepatitis group and with the levels of serum albumin in cirrhosis group, respectively. CONCLUSIONS: These results suggest that extracellular PLA might be involved in the exacerbution and progression of the chronic liver diseases.

BACKGROUND: Angiotensin convertiong enzyme inhibitors have been shown to exert favorable effects on the left ventricular remodeling process associated with ventricular dilation after coronary occlusion. However, the effects of such therapy on global and regional left ventricular remodeling after coronart artery reperfusion have not been characterized, nor have such effects been assessed after exercise training. METHODS AND RESULTS: Female Sprague-Dawley rats(n=80) were randodmized into 4 groups at 5 days after 45 minutes of left coronary artery occlusion followed by reperfusion. Animals completion the experiment included : Untreated Sedentary group(n=20), Untreated with Swimming Exercise group(n=21), Captopril Treated Sedentary group(n=18) and Captoril Treated with Exercise group(n=21). At 3 weeks after randomization, global and regional morphologic changes of the left ventricle(LV) were examined from mid-ventricular transverse slices which were perfusion-fixed at a constant aortic pressure of 60mmHg and a left ventricular cavity pressure of 10mmHG. At rest and during exercise, compared to untreated rats, the captopril treated animals showed significantly decreased LV weight/tibial length ratio(LV/TL)(p<0.01),increased LV cavity area and dimension(both p<0.01), decreased total myocardial area and noninfarcted area(both p<30.001) and reduced wall thicknesses in the noninfarcted and infarcted regions(both p<0.001). Compared to treated and untreated dsedentary rats, exercise significantly increased LV/TL(p<0.05) and epicardial and endocardial areas in the infarcted zone(both p<0.05) and decreased transmurality(p<0.01). Exercise decreased LV cavity area in the captopril treated groups(42.3+/-10.4 vs. 40.4+/-6.0mm2),whereas exercise increased LV cavity area in the untreated groups(33.5+/-8.9 vs. 39.1+/-6.2mm2)(p<0.05). CONCLUSION: These findings provide evidence in rats for evidence in rats for exaggerated left ventricular dilation and supperssion of compensatory myocardial hypertrophy globally and in the infarct zone with 3 weeks of captopril treatment following coronary artery reperfusion with acute nontransmural myocardial infarction. In addition, the effects of captopril on LV dilation and suppression of global and regional hypertrophic response were partially reversible by swimming exercise.

BACKGROUND: The skin prick test and in vitro allergen-specific IgE assays are commonly used to diagnose atopic diseases. However, there is still a need for comparison of their diagnostic efficiency. Objective and METHOD: To evaluate their clinical efficiency, the results of UniCAP and multiple antigen simultaneous test (MAST) were compared with skin prick test results. After 51 allergic patients completed skin prick test (SPT), serum sample was collected and UniCAP and MAST were performed to determine specific IgE to house dust mite (Dermatophagoides pteronyssinus : Dp and D. farinae. Df). Result : When SPT was used as a reference standard, UniCAP depicted higher sensitivity of 88.8% to Dp IgE and 91.4% to Df - IgE, but lower specificity of 73.3% to Dp IgE and 75.0% to Df - IgE. However, MAST had lower sensitivity of 75.1% to Dp-IgE and 71.4% to Df - IgE, higher specificity of 93.3% to Dp-IgE and 93.7% to Df - IgE. The values of UniCAP and MAST were significantly correlated with the reactivity grade of skin prick test, respectively. Additionally, the response of SPT was not apparently associated with ECP levels. CONCLUSION: These study results may suggest that both UniCAP and MAST are generally feasible for measuring house dust mite - specific IgE and that they are both replicable.

Ovarian tumor in pregnancy is not rare and benign cystic teratoma is most common ovarian tumor in pregnancy. Most ovarian tumor in pregnancy is found at first and second trimester but sometimes found at third trimester and it is difficult to make a decision for management. Moreover physician should consider fetal age and mother's condition, and weigh outcome of operation for complicated ovarian tumor in pregnancy. Torsion of ovarian tumor is not an uncommon complication during first trimester of pregnancy and puerperium but rare occurs during the third trimester of pregnancy. We have experienced a case of torsion of benign cystic teratoma of ovary which occurred at 37 weeks gestation in a 25 year-old woman. So we report this case with a brief review of literature.

A total of 162 patients with invasive cervical cancer was investigated retrospectively with a view to elucidate the efficacy of pretreatment staging procedures of application with intravenous pyelography, cystoscopy, rectosigmoidoscopy. All 72 intravenous pyelograms, 155 sigmoidoscopies, 158 cystoscopies were normal. Of 111 patients with stage Ib who had paraaortic lymph node biopsies, two patients had a positive node(0.02%). Of 51 patients with stage II who had paraaortic lymph node biopsies, five patients had positive paraaortic lymph node(10%). And the accuracy of computed tomography and magnetic resonance imaging in the evaluation of invasive cervical cancer was assessed. In evaluating stage of cervical cancer, clinical staging had an accuracy of 78.9%, compared with 65.7% for CT and 58.9% for MRI. And for detection of parametrial invasion, clincal staging had an accuracy of 85.9%, compared with 85.1% for CT and 78.9% for MRI. Both modalities were comparable in evaluating lymph node metastasis ( 76.1% for CT, 74.4% for MRI ). IVP, cystoscopy and sigmoidoscopy for staging procedure evaluated in this study are unnecessary and should no longer be performed in patients with early stage cervical cancer. In addition, paraaortic lymph node biopsies in the absence of clinically suspicious nodes are not warranted. Compared with CT and MRI, pelvic examination offered improved evaluation of cervical cancer staging, parametrial invasion, but CT and MRI was useful in detecting the pelvic lymph node metastasis which was nearly impossible by clinical evaluation.

bcl-2 and c-myc protein expression were studied in 44 epidermal (8 seborrheic keratoses, 21 squamous cell carcinomas, and 15 basal cell carcinomas), and 26 melanocytic tumors(8 nevi, and malignant melanomas) by immunohistochemistry using the specific anti-bcl-2 and anti-c-myc monoclonal antibodies. 14 out of 15 basal cell carcinomas(BCC) (93.3%) showed expression of bcl-2 protein, 12 of which (85.7%) showed coexpression of c-myc protein. In the melanocytic tumors, 7 out of 8 nevi showed bcl-2 expression (87.5%). Five of these 7 cases (62.5%) also showed c-myc protein expression. Eight of 18 malignant melanomas(MM) (44.4%) showed expression of bcl-2 protein and 7 of these 8 cases (38.9%) also showed c-myc protein expression. All seborrheic keratoses and squamous cell carcinoma(SCC) were negative for bcl-2 proteins. 12 of 15 SCCs(80%) were positive for c-myc protein. In conclusion, bcl-2 and c-myc proteins were coexpressed in BCCs, nevi, and MMs. Coexpression of bcl-2 and c-myc proteins in these tumors was statistically significant(p<0.01), while no considerable differences of bcl-2 and c-myc expression were found between nevi and MMs. These results suggests that bcl-2 may cooperate with c-myc to promote tumorigenesis of BCCs, nevi, and MMs(p<0.01).
