Air pollution in the traffic areas in Seoul during the winter season was studied. The average level of sulfur dioxide concentration was 0.24 ppm through the day. Lowest was 0.14 ppm at 2~4 P.M. when the highest vertical temperature gradient was indicated, and 0.33~0.29 ppm during 10 P.M. to 8 A.M. at night. Average level of dust was 4.65 mppcf (2.1~12.8 mppcf) and higher levels were shown at 10 A.M., 6 P.M. and 10 P.M. as 5.44, 4.73 and 5.01 mppcf respectively. The noise level in the main traffic areas was 73.5 db in the average during this survey, 75.1 db in the daytime and 65.6 db in the night (11 P.M. ~7 A.M.) in the average. Various air pollutants in auto-exhaust gases and noise of automobiles were studied, since those are main sources of nuisance in the traffic areas. Carbon monoxide in the "Corona" taxi, formaldehyde in the jeep, and carbon monoxide, formaldehyde and sulfur dioxide in the "Senara" taxi were measured respectively in high concentration and there was no significant difference in other gases among the various type of vehides. As regards average Overall noise level at ordinary driving speeds, heavy vehicles emitted much more noise (30 KPH) (82.2~83.5 db) than light vehicles such as taxi (40~5O KPH) (71.5-80.2 db). The noise level when starting heavy vehicles was higher 88.5 db(94.2 phon) on the average and that of light vehicles was lower 69.4 db (76.2 phon). There were two types of automobile horn noise in the octave band; one was in 1,000 cps and the other 2,000~4,000cps. The average horn noise level of automobiles was 98 db (107.8 phon), with 106 db (11.05 phon) maximum and 88.8db (99.5 phon) minimum. In the epidemiological study of CO poisoning in urban areas, there were 260 deaths out of 532 patients in 201 incidents of poisoning occurring on a total of 128 days during January 1964 to Dec. 1966. The concentration of co in the main living rooms and kitchens was detected as 58 and 112 ppm respectively, and the level of carboxyl-hemoglobin in the blood of housewives was relatively high, 11.2% on the average. In outside air maximal concentration of CO was 80 ppm in Shinchon-Dong an urban area.

Acute suppurative thyroiditis is uncommon in children. The relative rarity of thyroid infection is thought to reflect its complete fibrous encapsulation, generous vascular and lymphatic supply and high local iodine level. The bacterial involvement include the normal oropharyngeal microflora, and broad spectrum antibiotic therapy including anaerobic coverage should be utilized initially. We have experienced three cases of acute suppurative throiditis. All of them had painfull swelling on anterior cervical area and diagnosed by clinical and radiological features. Since two of them occured repeatedly, we report with brief review of literatures.

This study was carried out to determine the accuracy of Doppler echocardiography for predicting the pulmonary arterial pressure from right ventricular systolic time intervals in 52 patients with ventricular septal defect. The diagnosis of ventricular septal defect was made by cardiac catheterization and angiocardiography at Dong San hospital, Keimyung University during the period of one year from jan. 1988 to Dec. 1988. Doppler measurements of acceleration time (AT), right ventricular ejection time (RVET), right ventricular preejection period (RPEP), AT/RVET, and RPEP/AT were compared with pulmonary arterial pressure (PAP), measured by cardiac catheterization. The patients were divided into 3 groups : PAP< or =30mm Hg, PAP 31-59mm Hg, PAP??0mm Hg. The following results were obtained. 1) In the groups of PAP< or =30mm Hg, AT was 0.12+/-0.01sec, AT/RVET was 0.47+/-0.07 and RPEP/AT was 0.50+/-0.05. 2) In the groups of PAP> or =60mm HG, AT was 0.06+/-0.01sec. AT/RVET was 0.28+/-0.05. RPEP/AR was 1.51+/-0.21. As the level of PAP increased, Doppler AT, AT/RVET and RPEP/AT showed significant change(P<0.001). 3) The Doppler AT showed relative high correlation(r=-0.76) with PAP measured by cardiac catheterization in all group. 4) The Doppler AT/RVET showed correlation(r=-0.70) with PAP. 5) The Doppler RPEP/AT showed high correlation(r=0.91) with PAP. The Doppler echocardiography was easy to apply in all age groups, and was found useful for detecting pulmonary hypertension in ventricular septal defect and for the follow-up check of the patients. It may help to determine the optimal time for surgery and evaluation of the treatment.

Serum lipids and lipoproteins were determined in 70 patients with hypertension, 40 patients with cerebral infarctions, and 41 patients with cerebral hemorrhage. The results were compared with findings in 64 healthy controls. The results are as follows; 1) Total cholesterol, VLDL-cholesterol, LDL cholesterol and total cholesterol/HDL-cholesterol ratio were significantly higher in patients with hypertension or cerebral infarction than in control group, but HDL-cholesterol showed no significant difference. 2) In Patients with cerebral hemorrhage, total cholesterol, LDL-cholesterol and HDL-cholesterol were higher than in normal controls. Total cholesterol/HDL-cholesterol ratio was within the limits of normal. It is possible that the susceptibility to cerebral infarction is the result of high total cholesterol/HDL cholesterol ratio rather than low HDL cholesterol. But our study suggests that hyperlipoproteinemia plays a minor role in the development of cerebral hemorrhage.

BACKGROUND: Coronary arteriovenous(AV) fistula is a rare congenital disease, and seldom produce symptoms during childhood. However late complications can occur including congestive heart failure, myocardial ischemia, and bacterial endocarditis. Therefore surgical repair is recommended even if the patients are asymptomatic. In these days many investigators are interested in transcatheter embolization because of high procedural success rate without risks and morbidity associated with cardiac surgery. METHODS: Five patients(4 females and 1 male) of coronary AV fistula were treated with transcatheter coil embolization. All had symptom of chest pain. In coronary angiograms fistulous tracts were originated from left anterior descending artery(LAD) and drained to main pulmonary artery(MPA) in 4 cases. The other case had abnormal vessel from left circumflex artery(LCX) to bronchial artery. Transcatherter coil embolization were done with Judkins left guiding catheter, 018 inch Tracker or 3F Microferret catheter, and 018 inch coils. RESULTS: The fistula tracts were completely occluded in 3 cases after coil emboilzation. In 2 cases with multiple fistular vessels, major fistula were occluded, but minor vessels remained. There were no procedure related complications. CONCLUSION: Transcatheter coil embolization may be an effective treatment modality in coronary AV fistula with excellent result and minimal complications.

To evaluate the effect of Perindopril in patients with essential hypertension, we administered Perindopril 4 to 8mg/day once daily to 30 patients(18 males, 12 females) for 12 weeks. Baseline blood pressure after 4 weeks with placebo was 150.4+/-7.5/102.0+/-4.3mmHg. The blood pressures of the patients were declined significantly at 4th(140.6+/-14.9/95.4+/-6.5), 8th(136.7+/-11.4/91.7+/-7.6), and 12th(132.3+/-11.1/87.5+/-6.9) week(p<0.01) without change of heart rate. The blood pressure of the patients was normalized below 140/30mmHg in 24 patients(80%) and declined diastolic blood pressure more than 10mmHg in one patients. Therefore the response rate of perindopril was 83.3%. There were reported 3 patients who revealed mild adverse reactions as follows; cough, indigestion, dizziness in one each. In conclusion, these results indicate that antihypertensive therapy with perindopril single daily dose was effective in patients with mild to moderate essential hypertension and well tolerated.
