Questionaires on symptoms of respiratory disease have been used in Korea to elicit the probable health effects of air pollution in epidemiologic studies: The objectives of such studies often include comparing prevalence of symptoms of respiratory system between different population groups or between the same population groups, at different times. Unfortunately, little attention has, been paid to standardization of those questionaires, whether those are Korean. versions or not. Furthermore, no attempt to develop Korean ,questionaire on respiratory symptoms and relevant information has been made. Followed by 'a comparative study on responses to Korean version questionaires(English origin) of CMI, MRC, and ATS-DLD-78' two types of questionaires on respiratory symptoms and relevant information for Korean adult, which are short form (SUN-81-AS) and long forms (optional questions are added to the short one, SUN-81-AL), have been designed suitable to Korean background by authors (see Annex). The self-administered and closed-question questionaire were tested their validity and reliability by administration to l80 normal adults (medical and nursing students) and 60 clinical patients of Seoul National University Hospital, with spirometric exam. The results obtained and conclusions drawn are as follow: 1. It took less than 10 minutes to complete the questionaire SNU-81-AS and SNU-81-AL. 2. The test-retest reliability of each questions in AS and AL ,were observed as 92.7% and 92.1%, respectively. And all of the level of agreement are statistically significant with kappa statistic. 3. In addition to higher prevalence rate of symptoms in patients group compared, with, normal. group, the correlations between FEV 1.0/FVC predictive value(%) and number of symptoms were statistically significant inpatients group (See Fig. 1 and, Table 7). 4. The answer rate to optional questions in AL form among those who are not to do was about 10%, while the no-answer rate among who are to do was about 15% in Normal (medical and nursing students) group. 5. From the viewpoints of validity and reliability, the new Korean questionaire (SNU-81-AS and AL) developed by authors are to be recommendable to use in epidemiologic studies on respiratory illness in Korea. The self-administration, however, of optional questions in AL form may not assure the quality of data gathered.

The purpose of this study was to test the effect of the structured preoperative teaching on post-operative recovery and to observe the effects of an structured preoperative teaching on the adult surgical patient's ventilatory function ability, the length of hospital stay, the number of analgesics within a 72 hour postoperative period, the length of early ambulation. The research question investigated in this study was: What would be the effects of a structured preoperative teaching upon the adult surgical patients postoperative recovery? This study was based on a sample of 40 patients who were scheduled for abdominal surgery. They were asssigned alternately to experimental and control group. Among 40 subjects, 20 were placed in the experimental group and 20 in the control group. Preoperative ventilation function testing of control and experimental subjects was done the evening before surgery and before the patient received the structured preoperative teaching. A structured preoperative teaching was given to the subjects in the exporimental group only by writer. Postoperative testing was done the 5th postoperative day. The data were collected over a period of two months, from Aug. 8 to Oct. 31, 1983. For the analysis of the data and test for the hypotheses, the t-test with mean difference was used. The results of this study regarding the four-hypotheses were as follows: 1. Experimental group which received structured preoperative eaching will have more increase to-cough and deep breathe as measured byhis forced vital capacity(FVC), forced expiratory volume 1 (FEV1), maximal voluntary volume 15 (MVV 15) than control group without structured preoperative teaching. The ventilation function ability was more increase in experimental group than in control group, the mean difference was statistically significant at 0.01 level. Hypotheses 1 was supported. 2. Experimental group with structured preoperative teaching will have more reduced the length of hospital stay than control group without structured preoperative teaching. The length of hospital stay of the experimental group and control group were 11.90 days and 16.05 days respectively. However, the difference was. not statistically significant at .05 level. Therefore the hypothese 2 was not supported. 3. Experimental group with structured preoperative teaching will have more reduce the number of analgesics within a 72 hour postoperative period than control group. The number of analgesics within a 72 hour' postoperative period of experimental group and control group were 1.65 times and 2.4 times. The difference was not statically significant at .05 level. Therefore, the hypotheses 3 was not supported. 4. Experimental group with structured preoperative. teaching will have more reduce the length of early ambulation than control group without structured preoperative teaching. The length of early ambulation of experimental group and control group were 2.2 days and 3.5 days respectively The difference was statistically signficant at 0.05 level. Thus the hypothess 4 was supported.

Radionuclide cardioangiography has been widely applied and has played major roles in non-invasive assessment of cardiac function. Three techniques, first-pass, gated first and gated equilibrium methods, have commonly been used to evaluate right ventricular ejection fraction which usually abnormal in the patients with cardiopulmonary disease. It has been known that the gated first pass method is the most accurate method among the three techniques in assessment of right ventricular ejection fraction. The radionuclide right ventricular ejection fraction values were determined in 13 normal subjects and in 15 patients with chronic obstructive pulmonary disease by the gated first pass method and compared with those of the first pass method because there ha,j been no published data of right ventricular ejection fraction by the gated first pass method in Korea. The values of right ventricular ejection fraction by the gated first pass method were compared with the detas from the pulmonary function test performed in the patients with chronic obstructive pulmomary disease. The results were as follows: 1) The values of right ventricular ejection fraction by the gated first pass method were $50.1{\pm}6.1%$ in normal subjects and $38.5{\pm}8.5$ in the patients with chronic obstructive pulmonary disease. There was statistically significant difference between the right ventricular ejection fraction of each of the two groups (p < 0.05). 2) The right ventricular ejection fraction by the gated first pass method was not linearly correlated with $FEV_1$, VC, DLCO, and FVC as well as $P_aO_2$ and $P_aCO_2$ of the patients with chronic obstructive pulmonary disease. We concluded that right ventricular ejection fraction by the gated first pass method using radionuclide cardioangiography may be useful in clinical assessment of the right ventricular function.

Objective: Chronic obstructive pulmonary disease(COPD) is characterized by persistent airflow limitations associated with chronic inflammatory response due to noxious particles or gases in the lung. Inflammation and oxidative stress are associated with COPD. The aim of this study was to evaluate the relationship among inflammation, oxidative stress, and airflow limitation severity in retired miners with COPD. Methods: The levels of serum high-sensitivity C-reactive protein(hsCRP) as a biomarker for inflammation, degree of reactive oxygen metabolites(dROMs) and biological antioxidants potential(BAP) in plasma as biomarkers for oxidative stress were measured in 211 male subjects with COPD. Degree of airflow limitation severity as determined by spirometry was divided into three grades grouped according to the classification of the Global Initiatives for Obstructive Lung Disease(GOLD)(1, mild; 2, moderate; $3{\leq}$, severe or more) using a fixed ratio, post- bronchodilator $FEV_1/FVC$ < 0.7. Results: Mean levels of dROMs significantly increased in relation to airflow limitation severity(GOLD 1, 317.8 U.CARR vs. GOLD 2, 320.3 U.CARR vs. GOLD $3{\leq}$, 350.9 U.CARR, p=0.047) and dROMs levels were correlated with serum hsCRP levels(r=0.514, p<0.001). Mean levels of hsCRP were higher in current smokers(non-smoker, 1.47 mg/L vs. smoker, 2.34 mg/L, p=0.006), and tended to increase with degree of airflow limitation severity(p=0.071). Mean levels of BAP were lower in current smokers(non-smoker, $1873{\mu}mol/L$ vs. smoker, $1754{\mu}mol/L$, p=0.006). Conclusions: These results suggest that inflammation and oxidative stress are related to airflow limitation severity in retired miners with COPD, and there was a correlation between inflammation and oxidative stress.

The prevalence rate of pulmonary tuberculosis is 1.8% in 1990, and endobronchial tuberculosis may exist in 10 to 40% of active disease. Endobronchial tuberculosis usually leaves bronchial stenosis as the complication despite of modern chemotherapy, and it is often misdiagnosed as bronchial asthma. When bronchial stenosis involves major airway, its treatment needs such special measures as steroid therapy, surgical intervention and/or laser therapy, but the therapeutic result is often disappointing. To exploit a new treatment modality for bronchial stenosis, balloon dilatation was carried out in 12 patients with endobronchial tuberculosis. Under local anesthesia, 4F-Fogarty balloon was inserted via bronchofiberscope in ten cases and 10F-Gruentzig balloon was introduced under fluoroscopic guide in two others. Endobronchial tuberculoses were subdivided into two(16.7%) with actively caseating type, seven (58.3%) with fibrostenotic type, and three (25.0%) with stenotic type without fibrosis, according to the bronchoscopic findings. In 7 healed cases which were all stenotic with fibrosis, three (42.9%) took favorable turn in clinical status but four (57.1%) were not improved with balloon dilatation. In 5 active cases, all (two with actively-caseating type and three with stenotic type without fibrosis) were improved with this method. $FEV_{1.0}$ or FVC increased 10% or more after procedure in seven (70.0%) of ten and bronchial lumen remained enlarged in eight (66.7%) of twelve, in whom follow-up examination was done after the procedure. Balloon dilatation of bronchial stenosis is more effective, when endobronchial tuberculosis is in active stage than in healed fibrotic stage. It is suggested that bronchial stenosis can be minimized by early diagnosis and early application of balloon dilatation in the course of disease.

원인 질환이 동반된 속발성 자연기흉에 대한 개흉술은 수술 전후로 높은 위험율을 동반하나, 비디오 흉강경은 최소의 침습적 수술방법으로 치료 효과를 기대할 수 있다. 저자들은 비디오 흉강경술을 이용한 속발성 자연기흉에 대한 36 예(남 33 예, 여 3 예)의 환자에서 임상적 결과로서 유용성을 알고자 하였다. 대상의 평균 나이는 56.3세(범위, 31∼80세)였으며, 21 예에서 폐기종, 20 예에서 폐결핵을 동반하였다. 술전 폐기능 검사상 FEV1은 예상치의 59.3%, FVC는 예상치의 64.0%를 보였다. 19 예의 환자에서 술전 3일 이상의 지속적 공기유출을 보였고, 15 예의 환자에서는 한 번 이상의 재발 기왕력을 보였다. 36 예의 전 환자에서 기계적 흉막유착술을 시행하였으며 33예의 환자에서는 폐기포절제술(bullectomy) 및 폐기포배제술(bullous exclusion technique)을 시행하였다. 평균 수술시간은 97분이었다. 7 예에서 심한 유착을 보였으며, 10 예의 환자에서 폐상엽에 경미한 흉막유착을 보였다. 술후 지속적인 공기유출로 개흉술이 필요한 경우는 없었으나 1 예에서 술후 지속된 공기유출과 호흡부전으로 인하여 사망하였다. 술후 평균 입원기간은 7일(범위, 2∼17일)이었다. 술후 평균 15.8개월(범위, 5∼45개월)의 추적기간동안 기흉의 재발은 없었다. 저자들이 시행한 112 예의 원발성 자연기흉에 대한 비디오 흉강경술에 비하여 수술시간 및 치료 실패율에 있어서 통계적 유의한 차이를 보이지 않았으나 술후 흉강삽관기간 및 입원기간은 더 길었다. 개흉술을 시행하기에 위험한 비교적 고령의 속발성 자연기흉의 환자에서 비디오 흉강경술은 효과적이고 비교적 안전한 수술방법이라 사료된다.
