BACKGROUND: Recently, according to many studies, variable factors have been known to be associated with physical fitness. The factors such as obesity and inactivity are associated with poor physical fitness, but regular exercise is associated with good physical fitness. In our country, these studies are not yet reported. And so, this study was designed to investigate the factors associat,ed with physical fitness. METHODS: From May 1st, until July 30th 1996, we recruited the 411 subjects who visited the Health Promotion Center at Seoul National University Hospital. Data related to sex, age, exercise, job, cigarette smoking, alcohol consumption were obtained by self-administered Questionnaire. Obesity index was calculated by the percentage of standard body weight. And VO2max were obtained by submaximal bicycle ergometer test. High level exercise group was defined as the persons who had taken exercise more than 3 times a week and 20 minutes per session, and moderate exercise group was defined as the persons who had taken exercise one or two times a week and 20 minutes per session, and sedentary group was defined as the persons who had taken exercise more than 20 minutes less than one time per week. RESULTS: The subjects were 230 males(56%), total numbers were 411. The results were as follows. Compaired to women and nonexercise group, men and exercise group had high VO2max(p<0.005). The relationship between VO2max and age showed negative, and the VO2max of obese group(obesity index>_120) was greater than that of nonobese group. Any significant relationships between VO2max and job, disease were not found. In multiple regression analysis, significant relationships between VO2max and age, sex, exercise type, and obesity index were observed(p<0.01). CONCLUSIONS: We concluded that there were significant relationships between VO2max and obesity index, exercise group.

PURPOSE: There have been repoty on radiological features of lower respiratory track infection in infants and children caused by RSV(respiratory syncytial virus) in KOREA. The aims of this study were to summarize radiological features of lower respiratory tract infection caused by common viral agents other than RSV and to find any specific radiological features which might provide clue to the etiologic diagnosis. MATERIALS AND METHODS: We retrospectively analyzed radiological features in 51 children with symptoms of lower respiratory tract infection and identification of viral agents(except RSV). They included parainfluenza (n=22), adenovirus(n=16), influenza A(n--11), influenza B(n=2) virus infections. The mean age of the patients was 23 months. RESULTS: Major radiological findings of viral lower respiratory tract infection were bilateral parahilar peribronchial infiltration(62%), bilateral overaeration(60%), atelectasis(59%)(segmental or subsegmental atelectasis(43%), Iobar atelectasis(16%)) and patchy or confluent consolidation(20%). Pleural effusion was seen in only one case and hilar adenopathy was not observed in any of them. In the cares of adeno virus, consolidation was seen in 5 cases(31%) including 3 cases919%) of extensive confluent consolidations and overaerations were less frequent findings(44%) than in other viruses. In 24 patients with radiological follow up for more than 1 week, consolidation improved most rapidly, while was persistent atelectasis. CONCLUSION: The major radiologic features in vital lower respiratory tract infection(except RSV) were overinflation, bilateral peribronchial infiltration and atelectasis. In adenoviral infection, confluent consolidations which are usually seen in bacterial pneumonia were more common findings than in other viral lower respiratory tract infections.

Accumulation of leukocytes within the glomerulus is a key event in the pathogenesis of glomerulonephritis. This process is mediated by pairs of adhesion molecules. We have examined the expression pattern of selectins (E and P), intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1) in 30 renal biopsies with IgA nephropathy, diffuse crescentic glomerulonephritis, and minimal change disease. Normal controls were obtained from four nephrectomy specimens with renal cell carcinoma. ICAM-1 expression was significantly increased in the glomerular endothelial and mesangial cells in cases with IgA nephropathy compared with normal controls. VCAM-1 was expressed in glomerular mesangial cells in all cases with IgA nephropathy and diffuse crescentic glomerulonephritis, but faintly expressed in 3 cases with minimal change disease and not expressed in normal controls. P-selectin was faintly expressed in the glomeruli in cases with IgA nephropathy and diffuse crescentic glomerulonephritis. E-selectin was only expressed in the vascular endothelium in one case with IgA nephropathy and in the other with diffuse crescentic glomerulonephritis. ICAM-1 and VCAM-1 were strongly expressed in the crescents. However, selectin was not expressed in the crescent. These results suggest that adhesion molecules, particularly ICAM-1 and VCAM-1, play an important role in the pathogenesis of glomerular damage and crescent formation in primary glomerular diseases.

OBJECTIVE: This study was performed to determine the smoking status and its associated factors in military life among young Korean men to provide date for smoking prevention in military areas as a part of the health promotion program for soldiers. METHODS: 1,033 infantrymen serving in 17 military units, which are located in suburbs of K city, were enrolled in this study. A questionnaire on the soldiers smoking status and other various characteristics was obtained from October 2nd to 12th, 2000. Logistic regression analysis was performed on the various variables in order to determine the factors related to smoking. RESULTS: 1) 830(80.3%) out of 1033 subjects had smoked cigarettes and 759 persons(73.4%) were regular smokers. 2) Among the 734 soldiers who started smoking before their military service, 714 soldiers(97.2%) continued to smoke after, while 45 soldiers(15.0%) among the 299 non-smokers started smoking after joining the army. 3) Through the logistic regression analysis, the education level, specialty in the army, smoking amongst the friends they met before military service, smoking amongst soldiers in the army, dating girl friends, drinking, satisfaction with their army lives and the presence of convenient smoking places at the barracks were significant factors related to the prevalence of smoking in soldiers. CONCLUSION: the factors related with incidence of smoking in the army are the complicated interactions among the individuals personal background, general charcterisitcs of the solider and the special environment in the barracks. Therefore, to improve national soldiers' health, an active non-smoking campaign and education should be pushed to discourage smoking in the barracks.

BACKGROUND: Recent data suggest that the colonization rate of group B streptococci(GBS) in pregnant women and the incidence of neonatal infections by GBS is increasing trend in Korea, but the antimicrobial susceptibilities and serotypes in pregnant women have not been reported in Korea. So, we studied to define the antimicrobial susceptibility patterns and frequency of serotypes of GBS in pregnant women. METHODS: The susceptibility and serotyping of 60 GBS isolates from 27 pregnant women and four isolates from their two neonates were tested by an agar dilution method and agglutination test, respectively. The typing sera used in this study were Ia, Ib, II, III, IV, and V. RESULTS: Minimal inhibitory concentration range of 60 GBS from pregnant women were penicillin G 0.015-0.12 microgram/ml, vancomycin 0.5-2 microgram/ml, clindamycin 0.015-4.0 microgram/ml, chloramphenicol 2-4 microgram/ml, erythromycin 0.015-2 microgram/ml, tetracycline 0.5-256 microgram/ml, cephalothin 0.12-0.25 microgram/ml, ceftriaxone 0.03-0.12 microgram/ml, respectively. The resistance rate of GBS were 6.7% to clindamycin, 0% to erythromycin, and 98.3% to tetracycline. Most of GBS serotypes from pregnant women in decreasing order were Ib(48.3%), Ia(24.1%), III(20.7%). CONCLUSION: All GBS strains isolated from pregnant women are highly susceptible to commonly used antimicrobial agents with the exception of tetracycline. The low prevalence of severe neonatal GBS infections in Korea is not due to the absence of serotype III, but probably due to a low genital carriage rate of GBS by pregnant women.

A functional upper airway obstruction due to a vocal cord dysfunction(VCD) is characterized by a paradoxical adduction of the vocal cords throughout the respiratory cycle with no obvious organic cause for the obstruction. It commonly occurs paroxysmally and imitates acute asthmatic attacks, often in patients with coexisting asthma. They present with episodes of dyspnea associated with inspiratory wheezing that persists despite conventional asthma treatment and a flattening of the inspiratory limb of the flow-volume curve; an adduction of the vocal cord during inspiration. Failure to recognize concurrent vocal cord dysfunction and asthma has led not only to the excessive use of bronchodilators and corticosteroids, but also to intubation and tracheostomy. Here, we report a case of coexistent obstructive pulmonary disease and functional upper airway obstruction due to a vocal cord dysfunction where a bronchoscopy showed a paradoxical vocal cord motion and typical features of a variable extrathoracic obstruction and a lower airway obstruction on the Flow-volume loop during a symptomatic period.

BACKGROUND: Joint symptoms frequently occur in the course of antituberculous chemotherapy and tend to be ignored and overlooked, but in some cases, they are often very troublesome in obstructing ordinary life. Joint symptoms that develop during antituberculous chemotherapy need to be understood, but there are few materials describing them systematically. METHOD: This study enrolled 33 patients with tuberculosis treated with first line antituberculous agents for more than 6months. In the course of treatment, joint symptoms not associated with specific cause, such as pre-existing joint disease or trauma, were investigated and compared with those of the asymptomatic group, We confirmed the incidence of joint symptoms and factors associated with them. RESULTS: Nineteen of 33 patients (58%) had joint symptoms. Joint symptoms developed 1.9±1.4 months after the beginning of chemotherapy and lasted for 3.6±2.5 months. IN 18 of 19 symptomatic patients, multiple joints were involved : shoulder(10 patients, 53%), knee(10,53%), finger(6,32%). Joint symptoms were expressed as pain(19 patients, 100%), stiffness(7,37%) and/or swelling (3,16%). Fourteen patients (74%) took analgesics to relieve their symptoms and in 2 patients, antituberculous agents were discontinued because of the severity of their symptoms. The symptoms seem to be caused by agents other than pyrazinamide, but it was very difficult to identify the definite causative agent. In age, sex, underlying disease and serum uric acid level, no significant differences were noted between the two groups. CONCLUSIONS: Although joint symptoms are common during antituberculous chemotherapy, their development is difficult to predict. Because some joint symptoms can become very bothersome, the physician should pay close attention to these symptoms.
