Objective: This study reports on the effects of CheonPae-hwan among asthma patients.Method: This case study was conducted with two asthma patients who had visited a traditional Korean medicine clinic. CheonPae-hwan was prescribed to the two patients; we then evaluated the objective symptom changes through forced vital capacity (FVC) and forced expiratory volume at one second (FEV₁). Dyspnea-subjective symptom change was evaluated with the visual analog scale (VAS).Results: In case 1, FVC increased from 2.24 to 2.55 after treatment, FEV₁ increased from 1.86 to 1.99, and VAS decreased from 2 to 0. In case 2, FVC increased from 1.51 to 2.79 after treatment, FEV₁ increased from 1.12 to 2.22, and VAS decreased from 8 to 5.Conclusion: CheonPae-hwan appeared to be effective for treating the two asthma patients in our study.

Objectives: The aim of this study was to evaluate pulmonary function in patients with mandibular fractures and to determine the pattern of pulmonary functions in these patients. Materials and Methods: This was a cross-sectional study of pulmonary functions in Nigerian non-smoking patients with isolated mandibular fractures managed at our health institution from December 2015 to June 2017. Forced vital capacity (FVC), forced expiratory volume in one second (FEV₁), peak expiratory flow rate (PEFR), and ratio of FEV₁ to FVC (FEV₁/FVC) were measured for all participants using a portable spirometer just before treatment. The pulmonary indices were compared with the predicted reference values for Nigerians to determine the respiratory pattern. Results: Forty participants consisting of six females (15.0%) and thirty-four males (85.0%) with a female to male ratio of 1:5.7 were included in this study. The mean patient age was 34.5±13.1 years (range, 17-63 years). The mean FVC, FEV₁, FEV₁/FVC, and PEFR were 3.8±1.2 L, 3.0±1.0 L, 74.3%±13.8%, and 5.2±2.2 L/s, respectively. Comparison of data with predicted values revealed that 17 subjects (42.5%) had normal pulmonary function pattern while 23 subjects (57.5%) had features suggestive of obstructive and restrictive pulmonary function patterns. Conclusion: Isolated mandibular fractures presented with abnormal pulmonary function pattern.

Spirometry and regional function studies using 99m-Technetium were performed preoperatively to predict postoperative pulmonary function change in 34 patients who had various pulmonary resectional procedures at the Department of Thoracic and Cardiovascular Surgery, Seoul National University Hospital. Between two months and fourteen months postoperation all the patients were reinvestigated with spirometry and clinical examination to evaluate their functional respiratory status. The postoperative obtained values, especially forced vital capacity [FVC] and forced expiratory volume in one second [FEV1] among the other parameters were compared with the postoperative predicted values. Estimated values of FVC and FEV1 derived from preoperative spirometry and quantitative perfusion lung scan correlated well with the measured postoperative values. The linear regression line derived from correlation between postoperative estimated[X] and postoperative measured[Y] values of FVC and FEV1 in all patients are as follows; 1. Y=0.76x + 0.39 in correlation of FVC [r=0.91] 2. Y=0.88x + 0.17 in correlation of FEV1 [r=0.96],br> This method of estimation was one of the best methods of predicting postoperative pulmonary function change and valuable in determining the extent of safe resection and postoperative prognosis to a poor risk patient with chronic obstructive lung disease.

Purpose: Forward head posture is a typical symptom in people who use computers for long periods of time. Respiration is a complex function involving co-operation of muscular, skeletal, and nervous systems. Abnormal posture can have a negative effect on respiratory function. The purpose of this study was to investigate the relationship between forward head posture and respiratory function in young adults. Methods: Forty-six healthy subjects participated in this study. Craniovertebral angle was measured for assessment of the forward head posture. The respiratory function of all subjects was evaluated by measuring forced vital capacity (FVC), forced expiratory volume at one second (FEV1), forced expiratory volume at one second/forced vital capacity (FEV1/FVC) ratio, and peak expiratory flow (PEF). The baseline of forward head posture was less than 49 degrees. Results: : Significant differences for predicted FVC and FEV1 were observed between the two groups, however, no statistically significant differences in FEV1/FVC ratio and PEF were observed between the two groups. Conclusion: Results of this study demonstrate that forward head posture has a negative effect on respiratory function in young adults.

목 적 : 천식의 특징은 기도염증의 결과인 가역적인 기류제한과 기관지과반응성이다. 최근에 호기산화질소(exhaled nitric oxide; FeNO)이 비침습적으로 기도염증을 알 수 있는 지표로서 이에 대한 많은 연구가 있었다. 또한 FeNO는 천식의 중증도를 나타내는 데 이용되는 객담내 호산구수나 메타콜린 기도유발시험과 관련이 있다고 보고되었다. 이에 저자들은 간헐성 천식환자에서 폐기능검사와 호기산화질소와의 관계를 알아보고자 본 연구를 시행하였다. 방 법 : 2005년 4월부터 8월까지 경희의대부속병원 소아과에서 천식으로 진단되어 폐기능검사와 호기산화질소 측정이 가능하였던 5세부터 15세의 80명의 환자를 대상으로 하였다. 최근 4주내에 상기도 감염이 없었고, 부신피질스테로이드를 포함한 조절약물을 사용하지 않은 경우에 연구 대상에 포함하였다. 폐기능검사는 Microspirometer를 사용하였다. Eco Medics사의 Chemiluminescence NO-analyzer(CLD 88 sp, Duernten, Switzerland)를 사용하여 FeNO를 측정하였으며 폐기능 검사와 FeNO와의 상관관계 분석은 Spearman correlation coefficient를 사용 하였다. 결 과 : 1초간 강제호기량(forced expiratory volume in 1 second, $FEV_1$)의 평균은 $0.890{\pm}0.455L$이었으며 강제폐활량 (forced vital capacity; FVC)의 평균은 $1.071{\pm}0.630L$이었다. $FEV_1%pred$의 평균은 $98.39{\pm}34.27%$였으며 $FEV_1/FVC$의 평균은 $88.53{\pm}19.49$이었다. FeNO의 평균치는 16.88 parts per billion(ppb)이었다. FeNO 측정치는 $FEV_1$(r=0.345, P<0.01), FVC(r=0.244, P<0.05)와 유의한 상관관계를 보였으나 $FEV_1%pred$와 $FEV_1/FVC$는 FeNO와 유의한 상관관계를 나타내지 않았다. 결 론 : FeNO의 측정은 폐기능 검사와 함께 소아천식 환자의 관리에 유용하게 사용될 수 있는 신빙성있는 검사로 생각되며 측정 방법이나 측정치의 참고치 설정에 앞으로 많은 연구가 필요할 것으로 생각된다.

Purpose : We investigated the correlation between body composition and lung function in healthy adults. Methods : This study included 204 healthy adults in whom all measurements were obtained once, and all data were analyzed using the SPSS software for Windows, version 22.0. Pearson's correlation analysis was performed to determine the correlation between body composition (represented by the total body water, protein mass, soft lean mass, mineral mass, basal metabolic rate, fat-free mass, skeletal muscle mass, and body fat percentage) and lung function (represented by the forced vital capacity [FVC], forced expiratory volume in 1 second [FEV₁], the FEV₁/FVC ratio, maximum voluntary ventilation [MVV], maximum expiratory pressure [MEP], and the maximum inspiratory pressure [MIP]). All measurements were obtained by two investigators to improve reliability. A significance level of α=.05 was used to verify statistical significance. Results : Among the lung function measurements obtained in both men and women, the FVC, FEV₁, MVV, and MIP were positively correlated with the total body water, protein mass, soft lean mass, mineral mass, basal metabolic rate, fat-free mass, and skeletal muscle mass in men (p<.05). The FEV₁/FVC ratio was negatively correlated with the total body water, soft lean mass, mineral mass, basal metabolic rate, fat-free mass and the body fat percentage (p<.05). Notably, the FVC, FEV₁, and MVV were positively correlated with the total body water, protein mass, soft lean mass, mineral mass, basal metabolic rate, fat-free mass, and skeletal muscle mass in women (p<.05). Conclusion : This study showed a significant correlation between body composition and lung function in healthy adults. In combination with future studies on lung function, our results can provide objective evidence regarding the importance of prevention of lung disease, and our data can be utilized in rehabilitation programs for patients with respiratory diseases.

Theoretically one might suggest the abdominoplasty can cause respiratory decompensation resulting from musculofascial plication, which reduces the respiratory reserve by decreasing intra-abdominal volume and diaphragmatic excursion. This prospective study was perfomed to evaluate the effect of abdominoplasty and the change of intraoperative Paw on the pulmonary function of 20 consecutive otherwise healthy subjects. The pulmonary function test was performed preoperatively, and repeated 2 months after the operation. Additionally, we monitored intraoperative Paw. Comparison of the pulmonary function test showed a significant decrease(p<0.001) in the mean forced vital capacity(FVC) and the mean forced expiratory volume in one second($FEV_1$) throughout the study period. Postoperatively, the mean FVC decreased by 11.65% and the mean $FEV_1$ decreased by 16.15%. The mean Paw increased by $6.6cmH_2O$($3-12cmH_2O$) by musculofascial plication. And we found that the decrease in FVC and $FEV_1$ was significantly correlated with intraoperative changing of Paw in abdominoplasty(p<0.001). FVC and $FEV_1$ could be decreased by abdominoplasty due to decreasing intra-abdominal volume and diaphragmatic excursion, but there was no respiratory symptom clinically in all patients 2 months after the operation. In conclusion, We found that the decrease in FVC and FEV1 after 2 months of abdominoplasty was significantly correlated with intraoperative Paw change during operation. The intraoperative Paw was increased to $12cmH_2O$ without any respiratory symptom in this study. We suggested that the increase in intraoperative Paw less than about $10cmH_2O$ can not affect on respiratory function clinically.
