5.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.

6.Study on the Systolic Time Intervals in Normal Koreans.
Korean Circulation Journal 1978;8(1):9-15
The measurement of systolic time intervals has become one of the established quantitative noninvasive tests of cardiac function, especially of left ventricular performance, and remain one of the simplest and most reliable to perform. In an attempt to obtain the normal data of the systolic time intervals, we conducted a study in 89 normal Koreans of 43 males and 46 females. The measurements are obtained from the simultaneous high speed recordings (100mm/sec) of electrocardiogram, phonocardiogram, and indirect carotid arterial pulse. The results were as follows. 1. The QS2I, LVETI, and PEPI was 521+/-18 msec, 409+/-13msec, and 112+/-12 msec in males and 529+/-14 msec, 408+/-15 msec, and 121+/-11 msec in females, respectively. 2. The PEP/LVET ratio was 0.29+/-0.04 in males and 0.31+/-0.05 in females. 3. The QS2I and PEPI were significantly more lengthened in femals than in males, but other systolic time interval indices did not significantly relate to the sex. 4. The A2D was significantly shortened with age, but other systolic time intervals did not change with age. 5. According to the regression equations of QS2, LVET, and PEP to the heart rate, QS2 and LVET related more inversely to the heart rate than PEP.

7.Study on the Change of Serum Lipids.
Korean Circulation Journal 1975;5(1):1-17
To observe the effect of serious illness, surgical trauma, body weight, and clofibrate on serum lipids, the serum levels of cholesterol and triglyceride with lipoprotein patterns by electrophoresis on cellulose acetate membrane were studied in 30 normal persons, 18 patients with coronary heart disease, 26 patients with cerebral thrombosis, and 7 surgical patients. The results obtained were as follows; 1. The values of serum cholesterol and triglyceride in cerebral thrombosis and coronary heart disease were markedly higher than those of control, and the optic dinsities of each serum lipoprotein fractions were also increased significantly. 2. Serum lipoprotein type IIa and IIb were more frequently observed than type IV in cerebral thrombosis and coronary heart disease. 3. The change of serum cholesterol and triglyceride related moderately to relative body weight in normal persons. 4. The decrease in serum cholesterol occured on the 1st day following surgery, and recovered to 97.8% of the preoperation level on the 7th day. The serum triglyceride started to increase on the 3rd day following surgery, and reached to 115.1% of the preoperation level on the 7th day. 5. After attack of cerebrovascular accident the serum cholesterol and triglyceride level increased slowly to the 122.1% and 133.1% of the each lst day level on the 7th day. 6. The serum lipid lowering effect of clofibrate was most conspicuous in the hypertriglyceridemic patients, especially during lst and 2nd week after medication, and mixed hyperlipidemic patients responded moderately. But pure hypercholesterolemic patients resisted completely. The optic densities of each serum lipoprotein fraction were also decreased in drug responded groups.

8.Study on the Variation in Serum Lipids: On the Cholesterol, Triglyceride and Lipoprotein in Korean.
Korean Circulation Journal 1977;7(2):11-26
The serum cholesterol and triglyceride levels were measured and the lipoprotein patterns by electrophoresis on cellulose acetate membrane were observed in 30 normal Koreans, 26 patients with cerebrovascular accident, and 18 patients with coronary heart disease. Similar measurements and observations were made in normal Koreas, surgical patients, the patients with cerebrovascular accident and hyperlipidemia in an attempt to examine the effects of body weight, surgical operations, cerebrovascular accident and the administration of clofibrate on serum lipids. The results obtained were as follows. 1. The mean values of serum cholesterol and triglyceride, which shows moderately significant correlation to the body weight in normal Koreans, were markedly higher in the patients with cerebrovascular accident and coronary heart disease than those of control. 2. Serum pre-beta- and beta-lipoprotein patterns in the densitometry of the serum lipoprotein electropherogram of the patients with coronary heart disease were larger than those of control, but the densitometric patterns of the patients with cerebrovascular accident were similar to those of control. Serum pre-beta- and beta-lipoprotein-cholesterol levels of the patients with cerebrovascular accident and coronary heart disease were higher than those of control. 3. Serum hyperlipoproteinemic type IIa and IIb were more frequently observed than type IV in the patients with cerebrovascular accident and coronary heart disease. 4. Serum cholesterol levels decreased to 74.9% of preoperation levels on the 1st postoperative day and recovered to 97.8% of preoperation levels on the 7th day. Serum triglyceride levels started to increase on the 3rd postoperative day, and reached to 115.3% of preoperation levels on the 7th day. After attack of cerebrovascular accident, serum cholesterol and triglyceride levels increased slowly to 121.7% and 133.7% of the each 1st day levels on the 7th day. 5. Serum lipid lowering effect of clofibrate was most conspicuous in the hypertriglyceridemic patients, especially during the 1st and 2nd weeks after initiation of medication, and moderately in the mixed hyperlipidemic patients. Serum pre-beta- and beta-lipoprotein-cholesterol levels were decreased after 8 weeks of clofibrate therapy, but alpha-lipoprotein-cholesterol levels did not change significantly.

9.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.

Journal of the Korean Ophthalmological Society 1964;5(2):47-53
Central serous retinopathies were arbitrarily divided into two groups; one mainly with edema of the macula and the other with discoloration opacity and a number of tiny yellow spots in and around the macula. Eight cases of central serous retinopathy with macular edema were selected to have oral administration of chlordiazepoxide, 20mg to 60mg a day. Of eight cases of the variety, six cases showed a marked improvement of visual acuity and a complete subsidence of macular edema within ten days after the administration of the drug. Two other cases were also benefitted by the regime. The drug was found to be equally effective even in the patients who had been on the other treatments for varying lengths of time without success. The mode of action of the drug is not yet fully understood. It is, however, assumed that the effectiveness of the drug on the disease might be due to relief of the stress which, in turn, leads to the relaxation of spasm of the retinal and or choroidal arterioles in the vicinity of the macula.
