A very rare case of multifocal eosinophilic granuloma without extraskeletal involvement in 35 year-old ma was experienced. The patient was admitted for the painful swelling of the right clavicular region and was treati with curettage and autograft of iliac bone. Five months later newly developed the pain in the trochanteric lesion left femur without fever, and also was confirmed as the same lesion. Both lesions were treated with curettage and iliac bone graft, and were followed by radiotheraphy. According to the pathological study, those lesions were confirmed as the multifocal eosinophilic granuloma.

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.

OBJECTIVE: The study was performed to evaluate whether thallium reinjection (RI) distinguishes viable from nonviable myocardium among myocardial segments which showed persistent perfusion defect (PD) in patients with acute myocardial infarction (AMI). MATERIALS AND METHODS: We studied 22 patients underwent PTCA after AMI. SPECT was performed in all patients using dipyridamole stress- 4 hour redistribution (RD) followed by 24 hour RI protocols. Dysfunctional segs were classified into 5 groups: 1) normal, 2) reversible, 3) mild to moderate PD, 4) severe PD and 5) reverse redistribution (RR). All patients underwent follow up echocardiography after 4 months to assess regional wall motion (WM) improvement such as a criteria of viable myocardium. RESULTS: A total of 127 segs with abnormal WM was analyzed. Of 74 segs with PD, 17 (23%) showed enhanced uptake after 24 hour RI. Five of 17 segs (29%) with PD that responded to RI with enhanced thallium uptake showed WM improvement. WM improvement were seen in the 24 of 57 segs (42%) not responding to RI. All four segs (100%) with RR that responded to RI showed improvement. WM improvement were not seen in the 5 of 8 segs (71%) with RR not responding to thallium RI. Eleven (73%) of 15 segs with mild-moderate PD after RI showed improvement, but 33% of segs with severe PD after RI did not showed improvement. Segs with mild-moderate PD after RI and fill in after RI showed improvement in comparison to segs with severe PD after RI(p<0.05). CONCLUSIONS: These data indicate that because only small proportion of PD showed further perfusion improvement after RI and predictive value by the uptake after RI was low, there was limited role of RI after myocardial infarction. Usefulness of RI could be found in segs showing RR responding to RI in AMI reflects viable myocardium.

PURPOSE: We evaluated the importance of redistribution and 24 hour reinjection images in Tl-201 SPECT assessment of myocardial viability after acute myocardial infarction (AMI). MATERIALS AND METHODS: We performed dipyridamole stress-4 hour redistribution-24 hour reinjection Tl-201 SPECT in 43 patients with recent AMI (4-16 days). The myocardium was divided into 16 segments and perfusion grade was measured visually with 4 point score from 0 to 3 (absent uptake to normal uptake). A perfusion defect with stress score 2 was considered moderate. A defect was considered severe if the stress score was 0 or l (absent uptake or severe perfusion decrease). Moderate defect on stress image were considered viable and segments with severe defect were considered viable if they showed improvement of 1 score or more on redistribution or reinjection images. We compared the results of viability assess-ment in stress-redistribution and stress-reinjection images. RESULTS: On visual analysis, 344 of 688 segments (50%) had abnormal perfusion. Fifty two (15%) had moderate perfusion defects and 292 (85%) had severe perfusion defects on stress image. Of 292 severe stress defects, 53 were irreversible on redistribution and reversible on reinjection images, and 15 were reversible on redistribution and irreversible on reinjection images. Two hundred twenty four of 292 segments (76.7%) showed concordant results on stress-redistribution and stress-reinjection images. Therefore 24 hour reinjection image changed viability status from necrotic to viable in 53 segments of 292 severe stress defect (18%). However, myocardial viability was underestimated in only 5% (15/292) of severe defects by 24 hour reinjection. CONCLUSION: The 24 hour reinjection imaging is useful in the assessment of rnyocardial viability. It is more sensitive than 4 hour redistribution imaging. However, both redistribution and reinjection images are needed since they complement each other.

Supracondylar fracture is the most frequent injury of the elbow and frequently accompanies complications in children. Seventy two cases of supracondylar fractures have been treated and managed at Department of Orthopaedic Surgery, Catholic Medical College during the period from Jan. 1969 to Dec. 1972. The evaluation of fracture was done according to the classification of Holmberg and Hoyer. Among 72 cases of the supracondylar fracture, the most common type is 29 cases of Grade 2: (40.2%). Most cases were treated conservatively, and various method of treatment were adopted according to the condition of fracture. Residual angular deformities after successful manipulative reductiion can be accurately evaluated roentgenographically by the Baumanns method. Good results were obtained in 62.6%, fair results in 33.3%, and poor results in 4.1%. The incidence of cubitus varus deformity is 37.5%. There were no instance of ischemic contracture and no permanent neurological deficit in fracture cases.

The purpose of this study is to reveal how the road traffic noise influences on the response of teachers and students, which composed of conversation, studying, relation, and physical disturbances. The research method used in this study was self- administrated questionnaire. Samples of the survey were composed of 420 persons(l14 teachers and 306 students) who are exposed to traffic noise less than 65 dB(A) from two junior high schools and 410 persons(140 teachers and 270 students) from two noisy junior high schools which the road traffic noise above 65 dB(A). In the response of both of the teachers and students in noisy(above 65 dB) schools complaints of disturbances of conversation, studying, relaxation, and physical disturbances are much higher than that of less noisy schools' teachers and students(p<0.01 ). On the occasion of time and season, the subjects answered the traffic noise cause high troublesome and stresses in the afternoon(12:00-17:00) and summer respectively. It is necessary to provide governmental comprehensive and fundamental measures to improve the noisy school environments.
