Wingate test 및 Supramaximal exercise를 이용한 무산소성 운동능력의 측정시 나타난 변인의 관련성을 살펴본 본 연구를 요약하면 다음과 같다. Wingate test시 혈중젖산농도 최고치는 9.04±0.62mM로서 Supramaximal exercise시 보다 유의하게 높았으며, 혈장 LDH 및 CPK활성도는 두가지 운동부하후 모두 유의한 변화는 나타나지 않았다. 근전도상의 적분치, 중간파형빈도 및 평균파형빈도도 유의한 변화는 없었다. 등속성 수축시의 최대토오크는 양쪽 다리 모두에서 초당 60도의 각속도에서가장 높았다. Wingate test시의 최대파워는 등속성 수축시 최대토오크 및 Wingate test시 중간파형빈도의 직접적인 영향을 받는 것으로 나타났으며, 평균파워는 Wingate test시의 적분치 변화, 듣는 쪽 슬관절의 등속성 수축시최대토오크 및 Supramaximal exercise시 혈장 LDH 활성도의 직접적인 영향을 받는 것으로 나타났다. 이상의 결과에서 무산소성 운동능력과 관련지어 그 기전을 살피고자 할 때 체내 화학적 변화, 전기생리적 변화 및 발현능력의 복합성을 고려해야 하며 최대누적 산소결핍량의 활용가능성은 측정강도 결정방법을 중심으로한 계속적인 연구가 요구된다. The present study examined the relationship of variables related to anaerobic capacity with Wingate test and supramaximal exercise. Peak value of blood lactate concentration with Wingate test showeda significantly higher than suprammaximal exercise, and plasma LDH & median power frequency and mean power frequency were not any difference between two tests. Peak torque of isokinetic contractionh on knee joint showed a highest value in 60 degrees of angular velocity among a various angular velocity. Peak power of Wingate test was related to peak torque of isokinetic contraction and median power frequency of EMG with Wingate test, and mean power of Wingate test was related to integrated EMG with Wingate test, peak torque with isokinetic contraction of dominant knee joint and plasma LDH activity with supramaximal exercise. In this result, when it analyzed the mechanism of anaerobic capacity, ti was required the consideration of complexity according to biochemical alteration, electrophysiological alteration and revelation of performance, Appicapability of maximal accumulated O₂deficit was demaned a continuous study with the focus of exercise intensity.

<P>Childhood obesity seems to contribute to the development of vascular inflammation and the progression of arterial wall changes. High-sensitivity C-reactive protein (hs-CRP) has recently emerged as a useful biomarker for vascular inflammation associated with atherosclerosis. The objectives of this study were to evaluate the association of the serum hs-CRP level with ultrasonic findings of early atherosclerosis, carotid intima-media wall thickness (IMT) and brachial flow-mediated dilation (FMD), in obese children. Thirty eight obese children and 45 sex/age-matched healthy control children were recruited. Serum CRP levels were measured by the high-sensitive latex turbidimetric immunoassay, and we measured carotid IMT and brachial FMD using high-resolution B-mode ultrasonography. Obese children had significantly higher hs-CRP levels (1.40±0.74 mg/L vs. 0.55±0.49 mg/L, <I>p</I><0.01), as well as increased IMT (0.52±0.09 mm vs. 0.41±0.07 mm, <I>p</I><0.01) and impaired FMD (7.35±7.78% vs. 20.34±16.81%, <I>p</I><0.01) compared to healthy controls. Serum hs-CRP correlated positively with IMT (r=0.413, <I>p</I><0.05) and inversely with FMD (r=-0.350, <I>p</I><0.05) in the obesity group. Measurement of the serum hs-CRP level is a simple, cheap, and highly reproducible assay and correlates with IMT and FMD in obese children. Thus, it would be a useful marker for evaluating and estimating the degree of atherosclerosis in children.</P>

Congenital syphilis is a completely preventable disease, but it still occurs. It usually involves multiple organs, which may cause neurological or skeletal disabilities or death in the fetus or newborn. Although lung involvement is rare in congenital syphilis, we should consider pneumonia alba when respiratory symptoms or radiologic findings are abnormal. We first report herein two cases of pneumonia alba with high resolution computerized tomography (HRCT) findings. [Pediatr Allergy Respir Dis(Korea) 2009;19:300-306]

Background: Respiratory viral infections are common exacerbating factors for asthma in children. Recently the detection of respiratory viruses can be improved by using molecular biology techniques, which providing a method capable of detecting an increasing number of viruses. Objective: The aim of this study was to evaluate the causative viral infections and their seasonal trends in children who were admitted with the exacerbation of their asthma by multiplex polymerase chain reaction (PCR) assay. Method: Nasopharyngeal aspirates were obtained from hospitalized asthmatic children at Dankook University Hospital from November 2005 through Febraury 2007. Multiplex PCR assay was used for the detection of respiratory viruses. The demographic and clinical characteristics were reviewed retrospectively from the patients`` medical records. Result: During the study period, 58 were hospitalized due to acute asthma exacerbations. Of these, infectious agents were detected in 38 (65.5%) of the patients. Resipiratoy syncytial virus was detected in 18 (31%), influenza virus in 10 (17.2%), rhinovirus in 7 (12.1%), coronavirus in 5 (8.6%), adenovirus in 4 (6.9%), parainfluenza virus in 5 (8.6%) and human metapneumovirus in 2 (3.4%). Conclusion: It is suggested that the causative virus in hospitalized children with asthma exacerbations follow may the epidemic of respiratory virus in hospitalized children with respiratory infection.

Purpose: This study was aimed to investigate the clinical and epidemiological characteristics of the patients with acute bronchiolitis who visited in 146 Emergency Departments (EDs) in Korea in 2012. Methods: We used the NEDIS (National Emergency Department Information System) database to obtain all children with acute bronchiolitis who visited ED under the age of 3 between January 1, 2012 and December 31, 2012. Results: Totally 18,313 children with acute bronchiolitis were enrolled at this study. The male to female ratio was 1.55:1 and mean age was 10 months. The peak proportion was 17.3% in November during the whole year. The most common chief complaints were fever (38.5%), cough (37.4%), dyspnea (9.5%), gastrointestinal symptom (6.7%), and wheezing (2.5%). The most common accompanying disease was pneumonia (13.3%). The rate of hospital admission and intensive care unit admission were 34.5% and 0.3%, respectively. A predictor for admission via ED was respiratory difficulty. Conclusion: These data expand our understanding of clinical characteristics of patients with acute bronchiolitis who visited all ED in Korea in 2012. (Allergy Asthma Respir Dis 2015;3:334-340)
