We reoport a case of multiple basal cell carcinoma in a 51-year-old male who have taken a herb medication for right hemiplegia during 30 years. The patient had a 15-year history of the black colored, ulcerated nodules on left forehead and erythematous, protruded masses on back. Also, he had a 6-year history of black colored, ulcerated nodules on right temporal area of scalp and brownish, flat plaques on anterior chest, Biopsy specimens from lesions revealed typical histopathologic findings of the basal cell carcinoma. Wide excision with graft was done. One year later, he was expired due to lung carcinoma.

The E-cadherin, alpha-catenin, and beta-catenin expressions were immunohistochemically investigated in paraffin-embedded materials of 80 cases of colorectal adenocarcinomas. The staining similar to normal colorectal mucosa with preserved strong membranous staining pattern was considered normal or preserved expression. The X2 test was used to analyse the statistical correlation of cadherin/catenin expression with clinicopathologic parameters and the Breslow test for the correlation with survival length. Normal colorectal mucosa showed strong membranous expression of cadherin/catenin complex. The reduced E-cadherin, alpha-catenin, and beta-catenin expression were found in 53/80 (66.3%), 46/80 (57.5%), and 44/80 (55.5%) cases of colorectal cancers examined, respectively. There were significant correlations between E- cadherin and alpha -catenin (p=0.035), and between alpha-catenin and beta-catenin (p=0.013). The reduced E-cadherin expression was associated with histologic dedifferentiation, tumor depth, lymph node metastasis, clinical stage (p<0.05), poor clinical outcome in stage II (p=0.016) and the reduced alpha-catenin expression with lymph node metastasis and clinical stage (p<0.05). Reduced expression of two or more proteins was correlated with lymph node matastasis, histologic dedifferentiation, clinical stage, and survival (p<0.05). The present study demonstrates a significant down-regulation of E-cadherin and alpha-catenin expression in colorectal cancer is associated with tumor invasiveness, histologic dedifferentiation, lymph node metastasis, and clinical stage. These results suggest that E-cadherin and alpha-catenin may be useful markers of invasiveness, lymph node metastatic potential, and clinical stage and of value as prognostic markers in the earlier stage. Further studies are needed to confirm the prognostic value of these cadherin/catenin complex.

To investigate the human lung development and the distribution of elastic and reticular fibers during the fetal period proper, lung tissues taken from the periphery of the right lower lobes of Korean fetuses (n=49) of both sex were studied. The fetuses were the prodocts of spontaneous or therapeutic abortions and were found to have no associated lesions or anomalies at autopsy. The fetal age were estimated from crown-rump length or foot length. Paraffin sections, cut at 5-7 µm, were stained with routine hematoxylin and eosin for general structure, acid orcein and a1dehyde fuchsin for elastic fiber, and with Gomori's silver technique for reticular fiber, respectively. The lung development during fetal period proper, could be subdivided into three continuous periods according to the relation between airspaces, surrounding mesenchymal tissue, their structural changes and distribution, i.e., an early stage of the formation of conductive airways (pseudoglandular period, before 16th week of gestation), a middle stage of the development of lung parenchyma and new blood vessels (canalicular period, between 16th and 28th week of gestation), and a late stage of transition of respiratory portion to vascular organ (terminal sac stage, after 28th week of gestation). In places, secondary septa of sac or saccule formed by capillaries, capillary connective tissue, elastic and reticular fuel could be identified by the 33rd week of gestation. Elastic fibers could be noted in pleura, subepithelial areas of bronchioles and the wall of blood vessels in the late stage of pseudoglandular period. By the 28th week of gestation, elastic fibers were seen in the wall of small blood vessels or capillaries in the septal wall among the airspaces. And these fibers were observed in the tip of the secondary septa by the 33rd week of gestation but were not still completely developed in the walls of primary or secondary septa. Reticular fibers were already developed and widely distributed in fetal lung by the 10th week of gestation. These fibers were concentrated particular around the subepithelial area of bronchicoles, the airspaces and the blood vessel wall in the canalicular period. By the late stage of terminal sac period, reticular fibers formed a network along the small blood vessels in the septum of airspaces. These results indicate that primitive alveoli might be formed by the late stage of fetal period proper. The fibrous framework could partially formed by collagenous and reticular fibers during the pseudoglandular period, by addition of elastic fiber to the preformed network, and incompletely still finally by the three kinds of connective tissue fiber.

Erythromelanosis follicularis faciei et coli is a pigmentary disorder of unknown cause originally described by Kitamura et al in 1960. We describe two cases of erythromelanosis follicularis faciei et colli occured in adolescence. Clinical features of these patients were consistent with the clinical changes described in previous cases having clinical triad of erythema, hyperpigmentation and follicular papules. This pigmentary disorder may not be an uncommon disease, however it might be neglected from the concern of the dermatologists.

BACKGROUND: It has been reported that one or more intermittent reperfusion(s) during ischemia may be beneficial to the myocardium by washing out catabolites that have accumlated during ischemia. We evaluated the effect of four cycles of ichemia (2 minutes) and reperfusion (3 miutes), i.e., preconditioning on sustained ischemia (20 minutes) and reperfusion (60 minutes) using isolated Langendorff-perfused rabbit hearts. METHODS: After a fifty-minutes recovery phase, LVP , dLVP/dt and ECG were simultaneously recorded and ultrastructure of the stunned(or risk) area of the left ventricle was examined with conventional methods. RESULTS: In the preconditioned hearts, functional parameters such as LVPP(peak pressure), LVPP recovery rate and LVEDP(end-diastolic pressure) reached to 99.6+/-4.38mmHg, 98.0+/-4.67% and 14.0+/-2.90mmHg (109.3+/-2.91mmHg, 109.4+/-1.29mmHg and 10.7+/-2.67mmHg for the controls), respectively, after 30 minutes from the onset of reperfusion and maintained as in the controls(p>0.01). In contrast, in the ischemia-reperfusion hearts, LVPP and LVPP recovery rate were significantly reduced(81.6+/-6.83mmHg and 85.7+/-5.30%;p<0.05) and LVEDP elevated(21.2+/-3.00mmHg) but dP/dtmax, heart rate and ECG patterns were not significantly different between the preconditioned and the ischemia-refusion hearts during reperfusion. Furthermore, irreversible myocardial injury was homogeneous(both subendo- and subepicardial) in the ischmia-reperfusion hearts but only focal(subendocardial) in preconditioned hearts. CONCLUSION: These results suggest that preconditioning induced by very short periods of ischemia and reperfusion may enhance recovery of the left ventricular function and delay ultrastructhral changes to a certain extent during reperfusion.

PURPOSE: We reviewed the treatment outcomes and prognostic factors for patients with anal canal carcinoma who were treated with curative intent chemoradiotherapy (CRT) at Severance Hospital from 2005 to 2011. MATERIALS AND METHODS: Data for 38 eligible patients treated during this period were reviewed. All patients were treated with curative intent using radiotherapy (RT) with (n = 35) or without concomitant chemotherapy (n = 3). Among 35 patients who received CRT, most of the chemotherapeutic regimens were either 5-fluorouracil (5-FU) plus mitomycin C (23 patients) or 5-FU plus cisplatin (10 patients). Recurrence-free survival (RFS), colostomy-free survival (CFS), overall survival (OS), and locoregional control (LRC) rates were calculated using the Kaplan-Meier method and survival between subgroups were compared using the log-rank test. Cox's proportional hazard model was used for multivariate analysis. RESULTS: Over a median follow-up period of 44 months (range, 11 to 96 months), 3-year RFS, CFS, OS, and LRC were 80%, 79%, 85%, and 92%, respectively. In multivariate analysis, tumor size >4 cm was an independent predicting factor for poorer RFS (hazard ratio [HR], 6.35; 95% confidence interval [CI], 1.42 to 28.5; p = 0.006) and CFS (HR, 6.25; 95% CI, 1.39-28.0; p = 0.017), while the presence of external iliac lymph node metastasis was an independent prognosticator for poorer OS (HR, 9.32; 95% CI, 1.24 to 70.3; p = 0.030). No treatment-related colostomies or deaths occurred during or after treatment. CONCLUSION: Curative intent CRT resulted in excellent outcomes that were comparable to outcomes in previous randomized trials. No severe treatment-related toxicities were observed.

N,N-Diethylnitrosamine (DEN) has been proved to have carcinogenic potential in the initiation or promotion stage and the transformed cells proliferate to form preneoplastic nodules which are positive for placental form of glutathione S-transferase (GST-P). E-Cadherin, a member of the cadherin family, is expressed in epithelial cells. To evaluate the role of adhesion molecules (E-Cadherin, alpha-catenin, and beta-catenin), which have not been well understood in carcinogenesis, we investigated the changes of E-cadherin, alpha-Catenin and beta-Catenins by immunohistochemistry and immunoblotting in DEN-induced hepatocarcinogenesis of rat liver. In addition, the sequential analysis of histopathology and the expression of GST-P were also examined. Immunoreactive areas for GST-P were gradually increased from early period of carcinogenesis and strong GST-P positive foci were noted in various lesions, especially in the clear cell and eosinophilic cell nodules. Immunohistochemically, the E-Cadherin expression was increased in DEN-treated preneoplastic nodules in 4 and 10 weeks and hepatocellular carcinomas displayed relatively reduced expression compared with the hyperplastic nodules. But alpha- and beta-catenin expression was increased in hyperplastic nodules and hepatocellular carcinomas. Immunoblotting studies revealed that the level of alpha-catenin (cytosol and membranous fraction) was overexpressed in hyperplastic nodules as well as hepatocellular carcinomas, which showed markedly increased expression. The membranous fraction of beta-catenin was markedly increased in 10 weeks of DEN treatment and slightly reduced in hepatocellular carcinomas. These findings suggest that during DEN-induced hepatocarcinogenesis, the clear cell and eosinophilic cell nodules expressing GST-P in their cytoplasm are early transformed cell nodules. The altered expression of E-Cadherin and catenins is closely related with tumor propagation. Loss or reduced expression of E-cadherin may play a role in the progression of late hyperplastic nodule to hepatocellular carcinoma in DEN-induced rat hepato carcinogenesis.

PURPOSE: To obtain normative data on bone mineral density of each region of interest (ROI) measured by Hologic model dual-energy x-ray absorptiometry (DXA) of children and adolescents. METHODS: Cross sectional results from 723 healthy Korean children and adolescents (10-20 years of age) in the Korean National Health and Nutrition Examination Surveys were analyzed. We used age- and sex-specific reference data for bone mineral density (BMD) of the lumbar spine, femur neck, and total body except head from Hologic DXA device as recommended by the International Society for Clinical Densitometry. RESULTS: The bone mineral density of each ROI increased with age in both boys and girls. Maximal increase in the lumbar BMD occurred between ages 11 and 12 in girls and between ages 12 and 14 in boys. However, the increases of BMD in each ROI were different. The plateaus of the lumbar spine and whole body except head BMD in girls occurred at ages 15 and 17, respectively. The plateaus of BMD in each ROI occurred at age 17 in boys. CONCLUSION: Most of the skeletal mass, including lumbar spine and total body except head, is reached before the end of the second decade. This study provides reference values for bone density of each ROI measured with DXA for children and adolescents.

PURPOSE: MDM-2 is an oncoprotein that inhibits p53 tumor-suppressor protein. These abnor malities have a role in tumorigenesis through inactivation of p53 function. To determine the clini copathological and prognostic value of MDM2 abnormalities in gastric adendegrees Carcinoma, MDM-2& p53 protein expression were analysed in surgically resected materials of gastric adendegrees Carcinoma. MATERIALS AND METHODS: Fifty cases which had got follow-up after surgical resection were immunohistdegrees Chemically studied with p53 and MDM-2 antibodies. We defined variable clinico pathologic factors for expression of p53 and MDM-2 protein and analysed their relationships. RESULTS: Immunohistdegrees Chemical stain revealed expression of MDM-2 protein as a 52.0% (26/50) and p53 protein 20.0% (10/50), respectively. But their expressions were not assdegrees Ciated with clinicopathological factors such as T-factor, N-factor, stage, histology and differentiation. Overall, p53-negative patients seemed to have a better prognosis regardless of MDM-2 protein status (P= 0.057). MDM-2 protein status was considered to have no play as a prognostic factor. CONCLUSION: In the gastric adendegrees Carcinoma, p53 protein expression seemed to have a inverse relationship with clinical outcomes but MDM-2 protein expression, which was observed more frequently than those of p53, seemed not to be prognostic indicator.

PURPOSE: To compare the effectiveness of embolization of the bronchial artery embolization for the management of hemoptysis in pulmonary tuberculosis cases with the severity of lung parenchymal injury and pleural infiltration, as seen on plain chest radiographs, and with the findings of angiography of the bronchial artery. MATERIALS AND METHODS: Among 265 patients with hemoptysis due to pulmonary tuberculosis, the findings of plain chest radiography and angiography of the bronchial artery were comparatively analyzed in the 206 for whom the results of follow up were available. The chest radiographic findings were lassified as follows: Type I refers to simple pulmonary tuberculosis; Type II includes cases in which pulmonary tuberculosis is complicated by bronchiectasis, aspergillosis, or cavitation; Type III is either Types I or II accompanied by pleural infiltrates limited to the lung apex, and Type IV includes cases in which pleural infiltrates have extended beyond the apex in the whole of the lung. Bronchial angiographic findings were divided into four groups : Group I consists of cases which show abnormalities of only the bronchial artery; Group II includes those in which abnormalities are seen in the bronchial artery and either the internal mammary or an ntercostal artery; Group III comprises cases which belong to Group I or II and in which a branch of the subclavian artery is abnormal, and Group IV includes those in which abnormalities occur in at least two branches of the subclavian artery, or there is direct visualization of hypervascularity of this vessel. The initial post-embolic hemostatic effect and the results of follow up were studied over a six-month period. RESULTS: As compared with simple pulmonary tuberculosis (Type I), we found that as the severity of pleural infiltration and complications revealed by plain chest radiographs increased (Type II, III, IV), so did the severity of the manifestation of systemic collateral arteries other than the bronchial artery, as depicted by increase on bronchial angiography. Early post-embolic hemostasis occurred in 96% of Type-I cases (47/49), 82% of Type II (36/44), 70% of Type III (28/40), and 55% of Type IV (40/73). The average success rate was 74% (151/205). During the six month follow-up period, continued hemostasis was found in 80% of Type-I patients (36/45), 75% of Type II (30/40), 59% of Type III (20/34), and 48% of Type IV (20/42). The average long-term hemostasis rate was 66% (106/161). CONCLUSION: Bronchial angiography shows that in systemic collateral arteries circulation increases very substantially, and in cases in which plain chest radiographs depict extensive pleural infiltration or complications associated with pulmonary tuberculosis, it is therefore difficult to expect good hemostatic results after embolization. In such instances we thus recommend aggressive treatment such as surgical intervention.
