1.Characteristics of Gastric Cancer in Korea - with an Emphasis on the Increase of the Early Gastric Cancer (EGC).
Journal of the Korean Medical Association 2010;53(4):283-289
Gastric cancer is the most common malignancy and the second leading cause of cancer-related death in Korea. Age-adjusted annual incidence of gastric cancer per 100,000 persons is 62.8 for male and 25.7 for female. The proportion of early gastric cancer among surgically treated gastric cancer patients was 28.6% in 1995, 32.8% in 1999, and 47.4% in 2004. Screening upper endoscopy is quite commonly performed in Korea, and the proportion of early gastric cancer in the screened population is almost 75%. Gastric adenoma is considered to be a very important precancerous lesion. Gastric adenomas are actively treated in Korea, and at least 1/3 of the gastric adenomas with high grade dysplasia show cancerous focus when endoscopically resected. The prevalence of Helicobacter pylori is decreasing in Korean population, which may lead to the decreased incidence of gastric cancer in the near future. Paradigms of the diagnosis and treatment of gastric cancer are rapidly changing in Korea. Efforts to establish robust scientific data for new approaches are strongly required. The proportion of early gastric cancer among all gastric cancers has been and will be more increased in Korea.

Pityriasis rosea is sometimes accompanied with considerable pruritus. Ultraviolet B irradiation is reported to be beneficial in relieving pruritus. The purpose was to evaluate the effect of UVB phototherapy on severe pruritus of pityriasis rosea. Nine patients with severe pruritus had UVB irradiation three times a week Five patients became symptom free and three showed a marked improvement. One dropped out. UVB phototherapy could be an effective modality for relieving pruritus in pityriasis rosea.

A number of chronic inflammatory lesions of unknown etiology in man have recentlybeen understood by the mechanism of so called auto-immune disease and a series of experimental study using animals have been extensively undertaken to reproduce the lesion. Experimental chronic inflammatory diseases induced by repeated injection of homologous or heterologous tissue antigen with adjuvant are based upon immunological process and these are readily reproducible. The author has experimentally studied on any allergic destruction of the epididymis of the rat on immunologic process as in other particular organs and tissue. A total of 59 white healthy male rats were divided into 7 major experimental groups of injection as follows. Group 1: six rats, control, injection with normal saline alone. Group 2: six rats, injection with adjuvant only. Group 3: six rats. injection with epididymal tissue only. Group 4: twenty-three rate, injection with rat epididymal tissue plus adjuvant. A. seven rats, sacrificed on the 64th day B. ten rate, sacrificed on the 92nd day C. six rats, sacrificed on the 128thday Group 5. six rate, injection with rat epididymal tissue plus adjuvant plus prednisolone. Group 6: six rats, injection with rabbit epididymal tissue only Group 7: six rats, injection with rabbit epididymal tissue plus adjuvant Injections were given into the abdominal muscle of the rat once s week for 8 weeks as scheduled in the text and the animals of all groups except the group 4, were sacrificed 8 days after the final injection. In the group 4, animals were further divided into 3 subgroups which were sacrificed on the 61st, 92nd and l28th day of the experiment, respectively. The epididymis and other organs of allexperimental animals were studied histopathologically and the following results were obtained; 1. In all rats of the group 1 receiving homologous epididymal tissue with adjuvant, the epididymis revealed relatively marked and significant inflammatory changes. Histopathology included edema, congestion, fibrosis in the interstitial tissue, and infiltration of inflammatory cells mainly composed of lymphocytes, histiocytes, plasma cells and eosinophils. Flattening and hyperplasia of the epithelial cells and cellular exsudation were observed in the tubules. 2. In the group 1, the lapse of time after injection provoked more marked inflammatory changes. Diffusely mild or moderate degree of inflammation observed on 61st day, was changed to diffusely moderate or marked inflammation on 92nd day and then to significantly more chronic lesion with less exsudation and more fibrosis on 128th day. 3. Homologous tissue antigen without adjuvant andheterologous tissue antigen with or without adjuvant caused no inflammatory changes. 4. Inflammatory changes induced by homologous tissue antigen with adjuvant seem to be readily inhibited or prevented by simultaneous administration of prednisolone.

PURPOSE: The purpose of this study was to evaluate the effects of magnetization transfer contrast(MTC) andfat-suppression(FS) in variable spin-echo and gradient-echo sequences for articular cartilage imaging and todetermine the optimal pulse sequences. MATERIALS AND METHODS: Using variable 7-pulse sequences, the knees of 15pigs were imaged Axial images were obtained using proton density and T2-weighted spin-echo (PDWSE and T2WSE),turbo spin-echo (TSE), multiplanar gradient-echo (MPGR), and 3D steady-state gradient-echo (3DGRE) sequences, andthe same pulse sequences were then repeated using MTC. Also T1-weighted spin-echo(T1WSE) and 3D spoiledgradient-echo(3DSPGR) images of knees were also acquired, and the procedure was repeated using FS. For each knee,a total of 14 axial images were acquired, and using a 6-band scoring system, the visibility of and thevisibilities of the the articular cartilage was analyzed. The visual effect of MTC and FS was scored using a4-band scale. For each image, the signal intensities of articular cartilage, subchondral bone, muscles, and salinewere measured, and signal-to-noise ratios(SNR) and contrast-to-noise ratios(CNR) were also calculated. RESULTS: Visibility of the cartilage was best when 3DSPGR and T1WSE sequences were used. MTC imaging increased the negativecontrast between cartilage and saline, but FS imaging provided more positive contrast. CNR between cartilage andsaline was highest when using TSE with FS(-3 5 1 . 1 +/-15.3), though CNR between cartilage and bone then fell to-1 4 . 7 +/-10.8. In MTC imaging using MPGR showed the greatest increase of negative contrast between cartilage andsaline(CNR change=-74.7); the next highest was when 3DGRE was used(CNR change=-34.3). CNR between cartilage andbone was highest with MPGR(161.9 +/-17.7), but with MTC, the greatest CNR decrease(-81.8) was observed. Thegreatest CNR increase between cartilage and bone was noted in T1WSE with FS. In all scans, FS provided acartilage-only positive contrast image, though the absolute value of CNR was lower than that of MTC imaging. CONCLUSION: The most prominent effects of MTC and FS were seen in MPGR and T1WSE, respectively, though forcartilage, optimal high signal intensity and contrast can be achieved using 3DGRE with MTC, and 3DSPGR with FS.

The electrocardiography was performed to the 95 patients(58 male, 37 female) with chronic anemia in Department of Internal Medicine, Busan City Hospital, Busan University Hospital, Busan paik Hospital In-Je Medical College, Busan korea between April 1978 and March 1981. The hemoglobin levels were 4 Gm%-10Gm%, and the symptoms such as dizziness, palpitation, weakness, and appetite loss were continued for 6 months or more. The results were as following: 1. The abnormal electrocardiographic changes were observed in 49 of the 95 chronic anemic patients. 2. Prolonged QTc interval was observed in 12(12.6%) of 95 cases, depressed ST segment in 48(50.5%), inverted T wave in 32(33.7%), LVH in 31(32.6%), low voltage in 5(5.3%), and Rt. B.B.B. in 5(5.3%). 3. In the Hb level of 4.0~5.9Gm% 20% of the total 95 patients revealed prolonged QTc interval, 86.7% depressed ST segment, 40% inverted T wave, 20% LVH, 6.7% Rt. B.B.B., in the Hb level of 6.0~7.9Gm 10.6% prolonged QTc interval, 39.3% depressed St segment, 42.9% inverted T wave, 39.3% LVH, 3.6% low voltage and in the Hb level of 8.0-9.9Gm% 11.5% prolonged QTc interval, 46.1% depressed ST segment, 27% inverted T wave, 32.7% LVH and 7.7% low voltage.
