During a fire-year period from March 1979 to February 1984, 559 patients underwent surgical treatment for rheumatic mitral valve disease at Seoul National University Hospital. Left atrial thrombus was found at surgery in 74 of these patients, an incidence of 13.2%. This report outlines the surgical experience with these seventy-four patients. They were 32 men and 42 women, and their age ranged between 23 and 57 with mean of 42 years old. All except one had the findings of atrial fibrillation on the preoperative electrocardiogram. Ten [13.5%] had experienced embolic events before surgery. A history of one or more episodes of cardiac failure requiring digitalis and diuretics was noted in all patients Nineteen were associated with the aortic and/or tricuspid valve disease and closed mitral commissurotomy had been performed previously in four patients. The average cardiac index was 2.68L/min/M2 [1.59 to 3.47 L/min/M2] The mean systolic pulmonary artery pressure was 57mmHg [26 to 120 mmHg]and pulmonary capillary wedge pressure 21.5 mmHg [12 to 40 mmHg]. There were no significant hemodynamic findings to suggest the presence of the left atrial thrombus. Operative mortality was acceptable with two early deaths [2.7%]. The follow-up of the hospital survivors has shown excellent functional status.

At the Dept. of Thoracic and Cardiovascular Surgery of Pusan National University Hospital, postoperative cardiac catheterizations were performed in 12 patients of ventricular septal defect with severe pulmonary hypertension [Pp/Ps>0.75], who were operated during the period from July 1981 to Dec. 1986. The mean age of the patients preoperatively was 12.4 [range: 4-18] year-old and the mean follow-up duration was 25.8 [range: 8-53] month per patient. In comparison with the preoperative data, the systolic pulmonary artery pressure [SPAP] was decreased from 103.6*18.4 to 70.4*35.9 mmHg [p<0.01] and the Pp/Ps was decreased from 0.89*0.10 to 0.58*0.27 [p<0.01]. But the Rp/Rs and Rp were not meaningfully changed, from 0.31*0.16 and 7.6*0.4 unit to 0.41*0.32 and 8.0*6.6 unit, respectively. The preoperative Qp/Qs was bellow 2.0[mean: 1.6] in 3 out of 4 cases whose postoperative Rp/Rs and Rp were above 0.75 and 15 unit, respectively. On the contrary, the preoperative Qp/Qs was above 2.0 [mean: 3.5] in all of the 8 cases, whose postoperative Rp/Rs and Rp were below 0.50 and 10 unit, respectively.

Background: Painful experiences during procedures such as prolotherapy and intramuscular stimulation are stressful to patients and can affect the treatment outcome. We present a method for relieving pain and increasing the level of patient comfort during the procedure. Methods: Twenty six patients who requested sedation anesthesia during the procedure were examined. All patients were injected with 500 ml of 0.9% normal saline and were monitored by electrocardiography, blood pressure and pulse oximetry. The patients were supplied with oxygen (3 L/min) through a nasal cannula. Midazolam (0.02 mg/kg) and alfentanil ($8{\mu}g/kg$) was injected before the procedure and a bolus injection was administered during the procedure if patients felt any pain. The duration of the procedure, the total amount of drugs, the changes in the systolic blood pressure, heart rate, pulse oxygen saturation, sedation and pain level during procedure, satisfaction scale after the procedure, complications and the incidence of amnesia were evaluated. Results: Twenty one patients had a moderate level of sedation, 15 patients did not feel any pain during the procedure, 17 patients had high level of satisfaction (8-10). No patient experienced complications after the procedure, or unstable vital signs, and 6 patients could not remember the procedure. Conclusions: Sedation anesthesia is a safe method for relieving pain during the procedure, and most patients had a high level of satisfaction.

Changes in nutritional and health status brought on by a two-year balanced diet were assessed with anthropometric measurements as well as hematological and lipid profiles in 56 healthy young men. Recommended dietary allowances (RDA) were adjusted with estimated daily weighted activity factor. The weighted resting energy expenditure factor of the subjects was 2.37 $\pm$ 0.05. Compared with RDA, all nutrient intakes were adequate and 56% of energy was supplied by carbohydrates, 18% by protein and 26% by fat. The vitamin and mineral intakes except vitamin B-2 were higher (26.46-129.88%) than RDA. Vitamin B-2 intake was 92.15 \ulcorner 14.16% of RDA. There was no seasonal variation on nutrient intakes. Height was increased and systolic blood pressure was decreased by balanced diet for two years. Body weight, diastolic blood pressure and body mass index (BMI) were unchanged. The level of hemoglobin and hematocrit was not changed, the level of plasma protein was decreased and the level of plasma total cholesterol and albumin was increased. These results suggest that a balanced diet can increase height and complement health status achieved through vigorous exercise, even in adults, and that the level of Korean RDA for energy is adequate to maintain existing body weight.

Twenty two hypertensive and thirty normotensive in-patients were participated in this study to investigate the relationship between plasma renin activity and metabolism of Ca and Na, Prior to pharmacological treatments, renin activity, aldosterone and parathyroid hormone(PTH) levels were measured from the fasting blood samles. Twenty four hour urine samples were collected to analyze urinary levels of creatinine, Ca, Na and K. Habitual intake of Na and Ca were also measured for hypertensive and normotensive patients. Hypertensive subjects were classified into higher reinin hypertensive (HH), medium renin hypertensive(MH) and low renin hypertensive (LH) group according to their renin activities. PTH level of LH group was the highest among three hypertensive groups. It appeared that aldosterone levels of HH group were significantly higher than LH or MH groups(p<0.05). However there were no significan시 differences in aldosterone level between LH group and normotensive group. Habitual intake of Na and Ca were highest in LH group but lowest in HH group, however, they were not statistically different. Positive correlations of systolic blood pressure with PTH(r=0.2597) and aldosterone(r=0.26480existed(p<0.05). Urinary Ca level was positively correlated with urinary Na(r=0.5619), K(r=0.4533) and habitual Na intake(r=0.3253). Above results suggested the possible relationships among renin activity, habitual Ca intake and Na intake and suggested a further study on the interrelationship between the hormonal control of Ca and Na metabolism and blood pressure in hypertension.

This study was intended to figure out the effects of the amount and the distribution of body fat on the risk fators of adult disease. Sixty-four male college students paticipatied in this study, whose to find out body fat distributions were classified on the basis of Waist/hip ratio(WHR) into three groups-upper body type(UBTM), intermediate body type (IBTM) and lower body type(LBTM). Various risk factors such as adiposity, body fat ammount, serum lipid amount and blood pressure and their intercorrelations were analyzed. The three bodys type groups showed significant differences each other in weight(P<0.001), WHR showed considerable correlations with BMI and the percentage of body fat. The frequency of obesity assessed by BMI$\geq$25 and body fat percentage were the highest in the UBTM of the three groups. Thus, we could conclude that the closer the body fat distribution is to the upper body type, the higher the BMI and body fat percentage. Waist/girth ratio(WTR, P<0.01) and BMI(P<0.05) were positively correlated with serum triglyceride levels, and % of body fat was positively correlated with both serum triglyceride (P<0.01) and serum total cholesterol(P<0.05) levels. WHR (P<0.05), BMI(P<0.01) and % of body fat(P<0.01) also showed positive correlations with systolic blood pressure. From the above results, we could conclude that body fat distribution was a good index reflecting adiposity and body fat amount and that blood and serum amount of triglyceride was highest in the upper body type group showing the highest frequency of obesity.

The study aim was to investigate the antihypertensive effect after oral supplementation of dried radish leaves powder (DRLP). Angiotensin-converting enzyme (ACE) activity was measured by spectrophotometric assay. The systolic blood pressure (SBP) was measured in spontaneously hypertensive (SHR) and normotensive rats (Wistar) by the tail cuff method after a 4-week diet with DRLP at the level of 2.5% or 5%. The supplementation of DRLP decreased SBP of SHR although the 5% supplementation level did not show any more pronounced effect than the 2.5% level did. The decrease in the SBP observed for both 2.5% and 5% DRLP was accompanied by significant increases of the urinary Na and K excretion. The DRLP supplementation showed a potent ACE-inhibitory activity in pulmonary tissue from both hypertensive and normotensive rats. However, the DRLP supplementation did not affect the SBP in normotensive rats. These results indicated that DRLP exerted an antihypertensive effect in SHR due to the decreased ACE activity and increased urinary Na excretion.

The effects of the vegetable diet on the levels of the serum lipids, particularly the level of the serum total cholesterol which is most concerned with coronary heart disease (CHD) were investigated in 30 male SDA (Seventh Day Adventists) group and 30 male omnivorous group (control group). SDA participated in this study intaked relatively few animal origin foods whereas they intaked plant origin foods largely; they seldom or sometimes intaked meats, fishes, butter, margarine, beverages and coffee, but often unrefined cereals, legumes, vegetables and fruits. In the both systolic pressure and diastolic pressure, there was no difference between two groups. The levels of the serum total cholesterol, triglyceride and phospholipid were lower in SDA group than in the omnivorous group. Among them the difference was statistically significant in the level of the serum total cholesterol. HDL-cholesterol was more or less higher in SDA group than in the omnivorous group, but the difference was no significant. The result that SDA group had lower level of the serum total cholesterol than the omnivorous group suggested that that they might be less prone to CHD than the omnivorous group. Though this possibility, however, was derived from the fact of the lower level of serum total cholesterol of SDA group, it might by partly responsible for their habit that they never smoke and drink alcohols and coffee.

The purpose of this study was to investigate the relationship among nutrient intake, life style, and serum lipids level in 108 healthy middle-aged men in Taegu. A convenient method was to assess nutritional intake. Anthropometric measuement of body weight and hight were measured and average energy expenditure was calculated. The mean body mass index(BMI) was 22.8$\pm$2.4 and it was in the middle of the mean BMI of Korean men. Obesity rate of study subject were 13.2%. Daily energy intake was not sufficient as 88.4% of recommended dietary allowances and the energy percentage of carboydrate, fat protein was 65 : 21 : 14. Mean intake of vitamin A, B1, C and Ca were lower than RDA. There was a highly significant negative correlation between the systolic blood pressure and calcium intake(r=-0.28, p<0.05). Smokers showed significantly higher blood glucose than non-smokers. Skipping meals and uneven diurnal distribution(no breakfast and large evening meals) are associated with high triglyceride level in this population. There was a highly significant correlation between body weight and plasma lipids. Energy expenditure was negatively correlated with plasma triglyceride level. Especially, atherogenic index was significantly lower in job-time physically active worker than that in sedentary worker. Above data provides valuable imformation to the community for program planning as well as to health providers who work individual male adults to meet their nutrition needs and to control blood lipids.

Purpose: Many Korean college students suffer from physical inactivity and mental health problems. However, it has not been sufficiently reported how this lack of exercise and health-related behavior affect their health. The present study was performed to identify the relationships among physical activity level, health-promoting behavior, and physiological variables in Korean undergraduate and graduate students. Methods: Participants were 115 undergraduate and graduate students from one university in Seoul. The Pearson's correlation analysis was performed using SPSS for Windows. Results: Physical activity level had significant positive correlations with health-promoting behavior (r=.32, p=.001) and exercise self-efficacy (r=.25, p=.008), and health-promoting behavior had a significant correlation with depression (r=-.33, p<.001) and exercise self-efficacy (r=.44, p<.001). Additionally, physical activity level had significant correlations with triglyceride (r=-.20, p=.034) and vitamin D (r=.20, p=.029) levels. The high density cholesterol level had significant negative correlations with systolic blood pressure (r=-.33, p<.001), diastolic blood pressure (r=-.29, p=.002), and vitamin D (r=-.20, p=.035) levels. Conclusion: Physical activity level or health-promoting behavior had significant relationships with the health status of college students. Strategies need to be developed to improve health-promoting behaviors among college students.
