1.A Clinical Study on the Antihypertensive Effects of Lasix(R) Retard 30.
Korean Circulation Journal 1980;10(1):65-69
The antihypertensive action of Lasix(R) retard 30 was evaluated in 20 cases of essential hypertension on an outpatient basis. The following results were obtained. 1. The patient population comprised 11 males and 9 females, aged 32 to 67 years, with mild to moderate essential hypertension. mean age was 50 years, with 75% between 40 and 59 years of age. 2. The daily effective doses ranged from 1 to 3 capsules with an average of 1.7 capsules. The total duration of medication ranged from 4 to 12 weeks with an average of 6.5 weeks. 3. In 60% of the cases, good or fair control of blood pressure was resulted. Most of the poor results were in the cases of moderate hypertension, but the results could be improved with continuous treatment or combination with other antihypertensive drugs. 4. Transient dizziness and drowsiness were complained by 2 patients, but subsided spontaneously with continuous treatment. 5. In view of these results, Lasix retard 30 appears to be effective and well tolerated agent for the treatment of mild to moderate hypertension, either used alone or combined with other antihypertensive drugs.

By performing the county-wide surveys of Paragonimus westermani infection in several areas in the Chilgok county, Kyungpook Province, three endemic foci of Paragonimus westermani were found. The foci found in this survey were Haksan first dong, Haksan second dong, and Settom in Kumhwa village, all in Kasan myun, Chilgok county. In the three communities, the positive rates for the fluke among the residents by the intradermal test with Paragonimus antigen varied from 22.3 per cent to 25.0 per cent; school children from these areas showed infection rates above 50 per cent. The rate in males and females was 23.9 and 23.0 per cent, respectively. This difference was not significant. The presence and number of Semisulcospira snails and Astacus crayfish, the intermediate hosts of Paragonimus westermani in the stream communities and the high infection rates for the fluke in the residents were the supporting factors in determining the foci.

3.Clinical Electrophysiological Studies on the Chronic Recurrent Sustained Ventricular Tachycardia.
Korean Circulation Journal 1984;14(2):243-251
Clinical electrophysiological studies(EPS) were done in seven patients with chronic recurrent sustained ventricular tachycardia(VT) in an attempt to delineate the reproducibility and to select the effective antiarrhythmic drugs for the prevention of the recurrence of VT. We could induce and terminate the sustained VT, and could select the effective antiarrhythmic drugs in all patient in the cardiac catheterization laboratory with EPS. With these effective antiarrhythmic drugs VT did not recur for the follow up period of 15 to 20 months. In view of the serious nature of the VT and the demonstrated benefits of EPS, we could conclude that patients with chronic recurrent sustained VT should undergo EPS.

Background: Stomach cancer is the most commonly diagnosed malignant tumor in Korea. Early detection by mass screening very important to increase survival rate of stomach cancer, because the prognosis of early gastric cancer is excellent, and specific symptoms and physical findings are rare with early gastric cancer. Methed: 1865 car manufacturing company employees were examinined by gastrofiberscopy at a dispensary of the company from May 6, l992 to July 13, 1992. Results: 1. Number of cases with normal finding was 1262(67.7%), gastritis 422(22.6%), gastric ulcer 47(2.5%), gasrtric cancer 4(0.2%), duodenitis 39(2.1%), duodenal ulcer 63(3.4%), combined ulcer(gastric & duodenal) 2(0.1%,), post operative state 6(0.3%), and others 4(0.3%) in total 1865 examinees. 2. Of 422 cases with gastritis, cases with superficial gastritis were 171 (9.2%), atrophic gastritis 138(7.4%), erosive gastritis 94(5.0%) and hemorrhagic gastritis 19(1.0%). 3. Of 4 cases with stomach cancer, 1 case was advanced stomach cancer and 3 cases were early gastric cancer(two cases of IIc and one case of IIc+III) by macroscopic classification. Conclusion: Mass screening provides an excellent opportunity to detect gastric cancer in populations without symytoms or with nonspecific symptoms. It should be recommended to undergo screening exam for high risk group of stomach cancer.

Serous cystadenoma of the pancreas, also known as microcystic adenoma or glycogen-rich cystadenoma, is an unusually benign tumor. It is usually large and composed microscopically of many small cysts lined by small, cuboidal or flattened cells containing abundant glycogen. It has been suggested that serous cystadenoma probably arise from the ductular cells or centroacinar cells. Herein, we report on a case of serous cystadenoma of the pancreas in a 55-year-old female. The tumor, measuring 13.5x11.5x10.0 cm, was located in the head of the pancreas and the cut surface revealed a sponge-like appearance due to innumerable tiny cysts containing clear serous fluid. Microscopic analysis showed cystic spaces lined by cuboidal cells with intracytoplasmic glycogen.

The antiarrhythmic effect of Mexiletine was evaluated in five patients with recurrent ventricular tachycardia and in twelve patients with frequent premature ventricular contractions. Electrophysiologic study was performed on the the patients with recurrent ventricular tachycardia before and after the administration of Mexiletin(600-800mg/day). The antiarrhythmic effects of Mexiletine in the patients with frequent premature ventricular contraction was assessed by ambulatory electrocardiography. The results were as follows: 1) In all of the five patients with recurrent ventricular tachycardia, sustained ventricular tachycardia was induced by programmed ventricular stimulation. However, on repeated electrophysiologic study performed while receiving Mexiletine, ventricular tachycardia was not induced in four patients and non-sustained ventricular tachycardia was induced in one patients. 2) The number of premature ventricular contraction was decreased markedly in seven patients(58.3%) with frequent premature ventricular contractions. 3) Minimal side effects, mild indigestion and tremor, were recorded in 3 cases(23%) while receiving Mexiletine 600 mg/day. The higher dose was associated with more frequent and severe side effects.
