날씨가 차고 건조해지면 우리 몸의 호흡을 관장하는 폐도 예민해진다. 그런데 폐는 피부와도 관련이 깊다. 한의학에서는 피부와 털을 폐가 주관한다고 본다. 폐 기능이 떨어지면 피부 건강에도 악영향을 미치기 마련. 대신 좋아지면 얼굴빛부터 달라진다. 몸 속 유해물질을 배출하고 피부까지 챙기는 폐 기능 강화식품 베스트 4.

Background : Patients with locally advanced non-small cell lung cancer are often treated with radiation alone or in combination with chemotherapy. Both modalities have a potentially damaging effect on pulmonary function. In order to examine changes in the cardiopulmonary exercise function of patients with locally advanced non-small cell lung cancer before and after conventional radiotherapy, we conducted a prospective study involving patients with such cancer, that had received radiation therapy. Method : Resting pulmonary function test, thoracic radiographic finding and cardiopulmonary exercise test(CPET) were assessed prior to and 4 weeks following radiation therapy in 11 male patients with locally advanced non-small cell lung cancer. Patient with endobronchial mass were excluded. Results : The forces vital capacity (FVC), forced expiratory volume in 1 second ($FEV_1$ and maximal voluntary ventilation (MVV) did not decreased between before and 4 weeks after radiation but the diffusing capacity (DLCO) had decreased by 11% 4 weeks after radiation, which was not statistically significant. No changes in maximal oxygen consumption ($VO_2$max), carbon dioxide production ($VCO_2$), exercise time and work load were attributed to radiation therapy. Follow up cardiopulmonary exercise testing revealed unchanged cardiovascular function, ventilatory function and gas exchange. No difference in cardiopulmonary exercise test performance was observed between pre- and post-radiation. Conclusion : Cardiopulmonary exercise function did not decrease within the short-term after the radiation of patients with locally advanced non-small cell lung cancer.

Mostly lung diseases by smoking and air pollution is increasing social interest one of 6 kinds of modern diseases which is difficult functional recovery of damaged lung as dangerous diseases of life extension. Therefore, to reduce suffering from respiratory diseases is usually non-smoking, to do strengthen behavior of lung function. In this paper, we would like to propose method to do investigation by voice analysis technology to apply when lung associated ear acupuncture point stimulus to help strengthen actually lung function. From this, we would like to consider the voice change of before/after in smoking to analyze the impact on the human body to the lungs. Based on this experiment, we would like to investigate numerically quantity data actual improved lung function to analyze of voice character difference of before/after in lung associated ear acupuncture point stimulating.

의료기기들 중 기능 영상을 보기 위해 이용되는 PET 장치에서 획득된 결과 영상은 선명하지 않기 때문에, 해부학적 구조와 기능 영상을 동시에 보기 위해서는 선명한 영상을 제공하는 CT 와 PET 장치와 하나로 통합하여 영상을 획득하게 되었다. 그래서 한번의 촬영으로 PET/CT 영상을 얻을 수 있게 된 것이다. 서로 다른 특성을 갖는 이미지를 융합하게 되면 보다 정확한 진단을 내리는데 많은 도움을 준다. 본 논문은 CT 영상에서 폐 영역을 반 자동(Semi-Auto)으로 분리한 후 PET 영상에 자동으로 융합하는 방법을 제안한다. 반 자동 폐 영역 분할을 위해 1 차원 신호 처리 기법과 Seeded Region Growing 기법을 사용한다. 수행된 폐 분리 결과는 몸의 해부학적 구조를 보기 위해 사용되는 CT 영상에서 추출한 폐 영역을 기능을 보기 위한 PET 영상에 퓨전 함으로서 진단 전문가가 보다 정확한 진단을 하는데 도움이 될 것이다. 또한 이러한 기능을 쉽게 구현하고 사용할 수 있도록 시각 프로그래밍 기법을 접목하였다.

Purpose Lung Ventilation Scan(LVS) images directly inhaled radiation gas to evaluate lung ventilation ability. Therefore, it is influenced by various factors related to inhalation, including number of breaths, respiratory duration, respiration rate, and breathing method. In actual LVS examinations, it is difficult for objectify the patient's ability to inhale, and there is currently no known index related to inhalation. Therefore, this study confirms the correlation between counts per second(cps) in LVS and the results of pulmonary function test(PFT) and evaluate its usefulness as an objective indicator of inhalation. Materials and Methods From October 2010 to September 2018, 36 Chronic Obstructive Pulmonary Disease(COPD) patients who had both LVS and PFT were classified by severity(Mild, Moderate, Severe). LVS was performed by creating Technegas with Vita Medical's Technegas Generator and inhaling it to the patient. LVS images were acquired with Philips's Forte equipment., and PFT used Carefusion's Vmax Encore 22. The correlation between the cps measured by setting the region of interest(ROI) of both lungs on the LVS and the forced vital capacity(FVC), forced expiratory volume in one second($FEV_1$), $FEV_1/FVC$ of the results of PFT was compared and analyzed. Results We analyzed the correlation between cps of LVS using Technegas and the results of PFT by classifying COPD patients according to severity. Correlation coefficient between $FEV_1/FVC$ and cps was Severe -0.773, Moderate -0.750, and Mild -0.437. The Severe and Modulate result values were statistically significant(P<0.05) and Mild was not significant(P=0.155). On the other hand, the correlation coefficient between FVC and cps was statistically significant only in Mild and it was 0.882(P<0.05). Conclusion According to the study, we were able to analyze correlation between cps of LVS using Technegas and the results of PFT in COPD Patients. Using this result, when performing a LVS, the results of PFT can be used as an index of inhaling capacity. In addition, it is thought that it will be more effective for the operation of the exam rooms.

Lymphangioleiomyomatosis (LAM) is a rare disease in women of childbearing ages that eventually leads to respiratory failure. Lung transplantation is the only conclusive therapeutic modality in end-stage LAM. While single-lung transplantation is the preferred operation, the graft failure or recurrence of LAM was reported. We performed a single lung transplantation on a 36-year-old woman suffering from respiratory failure due to lymphangioleiomyomatosis. After a 1-year follow up, the patient was readmitted because of graft failure with collapsed transplanted lung. The lung volume reduction surgery (LVRS), tracheostomy and ventilator care were performed. However, neither the medical nor surgical treatment had any effect. Subsequently, we performed a contralateral single lung re-transplantation and had a good postoperative results.

Although lung transplantation has been accepted as the most effective treatment for end-stage pulmonary emphysema, it is not only very hard to find a donor but also to obtain a relatively healthy lung. Furthermore, it is more difficult to match the size of the allograft, considering the height, the weight, and the size of the thoracic cage. The single lung transplatations for the end-stage emphysema have been more commonly performed than bilateral lung transplantation due to the shortage of the donors and the long-term survival rate of the single lung transplantations has shown no reasonable difference compared with that of the bilateral lung transplantationh. Recently, the functional criteria based on a comparison of predicted TLCs(Total Lung Capacities) of the donor and recipient according to height, sex and age, have been accepted at a more suitable.

폐는 산소가 많이 포함된 신선한 공기를 혈액에 공급하여 줌으로써 우리 몸의 활동유지에 필요한 산소를 공급해 줌과 동시에 신체의 활동에 의하여 생성된 이산화탄소를 몸밖으로 배출하는 작용을 주로 하는 기관이다. 따라서 폐는 본연의 기능을 유지하기 위하여 계속적으로 외부의 공기를 흡입하여야 한다. 이 과정에서 외부에서 균으로 오염된 공기를 흡인하거나 또는 폐에 도달되기 전에 공기가 거쳐 지나가게 되는 구강 및 인후가 균으로 오염되어 있다가 오염된 분비물이 기도로 흡인되거나 하는 경우에는 폐실질에 염증이 발생할 수 잇는데, 이러한 경우를 폐렴이라고 한다. 이밖에도 다른 외부장기의 감염이 혈행성으로 폐로 전이되어서 폐렴이 발생할 수도 있다. 폐렴의 원인균은 각종 세균, mycoplasma, chlamidae, rickettsiae, virus 등 매우 다양하며, 균이 아닌 자극성 물질 또 호산구의 폐침윤 등에 의해서도 폐렴이 발생할 수 있다.

In this paper, using a image processing techniques to develop an color analysis program to apply the influence analysis by smoking were analyzed. So, this study was conducted to analyze is based on oriental medicine diagnosis theory, especially ocular inspection, of the right cheek area of the lung and lung function and weakness associated with it closer to white by applying IT image processing techniques based on smoking to compare the change in color according to the face. From this, 15 patients with 20 male subjects before and after smoking extract the color of the area on the right cheek, a values and b values in Lab digital color system were analyzed by smoking how to analyze what is changing. Also, health care system based on this variation reflects the individual, personalized will be constructed. Experimental results on the right cheek area approach to the color white according to the amounts of smoking, this is by smoking adversely affects lungs function that can be analyzed.
