환절기나 겨울철에 사람들은 독감, 천식, 비염 등 호흡기성 질환의 발병율이 높아지는 것과 동일하게 닭에서도 호흡기성 질병이 발생된다. 더군다나 닭은 어느 동물보다 호흡기를 구성하고 있는 실질장기들의 표면적이 넓어 그 만큼 많은 병원체에 쉽게 감염되며, 이에 따라 양계농장에서는 이들 전염병으로 피해가 속출하고 있다. 밤낮 기온차가 큰 환절기나 추운 겨울철에는 계사내 보온과 에너지절약, 이 두 가지 효과를 동시에 얻기 위해 노력하다 보면 신선한 산소의 제공

방사선치료의 발전으로 3차원치료보다 진보된 호흡연동방사선치료가 시행되어지고 있다. 호흡의 규칙성과 환자의 위치 재현성이 중요한 치료적응 인자이며, 호흡연동 방사선치료의 효율을 높일 수 있는 지표이다. 국가암통계상 고령의 암환자가 증가하며, 수술, 화학요법을 병행하는 암 치료법이 널리 이용이 되고 있다. 고식적인 치료를 요하는 고령의 복부 암 환자분들에 호흡연동 방사선치료법을 사용하는데 에는 호흡의 불규칙성과 체위의 재현성의 문제점으로 인한 치료 효율의 저하를 가져온다. 본 연구에서는 호흡에 의한 종양 움직임이 있는 방사선 치료에서 내부표적체적 기반의 치료계획과 호흡연동 기법을 적용한 치료계획과의 선량비교 분석하였다. 2가지 치료법 모두 정상조직 보호선량에 부합한 것으로 나타났으며 치료체적은 처방선량의 95%이상 포함된 선량분포로 적합하였다. ITV 설정을 통한 3D Plan은 고식적 치료을 목적으로 하는 고령의 환자, 체위 및 호흡의 불안정성 환자에게 처방선량의 95% 이상의 4D Plan의 치료법 보다 짧은 시간에 치료함으로써 치료효율을 높일 수 있을 거라 사료된다. 다만 정상조직보호선량(NTCP)에 부합하는지에 대한 평가가 전제되어야 한다.

Objectives : Although dysfunctional breathing is a common symptom in general population and affects qualities of life, it is still underdiagnosed. There are some studies of prevalence of it in astma, but few studies in anxiety and depressive disorders. The purposes of this study were to explore the prevalence of it in anxiety and depressive disorders, and to investigate whether anxiety and depressed mood influence it. Methods : 135 patients diagnosed with anxiety or depressive disorders, and 124 controls were recruited. Nijmegen questionnaire was used to assess dysfunctional breathing, and Hospital anxiety depression scale was used. Results : The prevalence of dysfunctional breathing in anxiety or depressive disorders was higher than that in control. In the linear regression model, anxiety accounted for 59.6% of dysfunctional breathing, but depressed mood did not. With covariate adjusted for anxiety, scores of dysfunctional breathing in anxiety or depressive disorders were higher than in controls. Conclusions : Dysfunctional breathing in anxiety or depressive disorders is higher than that in control. Adjusting anxiety, its difference is still. Anxiety affects dysfunctional breathing, but depressed mood does not.

We review three methods of separating soil respiration into root and soil microbial contribution: (1) component integration, (2) root exclusion, and (3) isotopic method. Among these methods, component integration and root exclusion are most commonly used. Root respiration contribution to soil respiration estimated by the root exclusion method is higher than those by other two methods. Trenching has little environmental disturbances in soil or on surface of site compared to other methods in root exclusion such as root removal and gap formation. Isotopic method has an advantage over other methods because of minimal soil and root disturbances, but this method is costly and requires techniques for the complex analysis. Trenching seems to be an appropriate in situ method for calculating component contributions to soil respiration with minimum disturbances in site. However, the method overestimates the contribution of microbial respiration because of root decay, and realistic results could be obtained by estimating root decay or avoiding large roots in trenched plots.

We report two cases of the thoracoscopic thymectomies for patients of myasthenia gratis with tracheostomy (Osserman's Group-ll-C-1). The Irst case was 47-year-old male wlth generalized myas- thenia gravis who was under the mechani al ventilator therapy with tracheostomy. The second case was 60-year-old male with deteriorating generalized myasthenia gratis after the mechanical ventilator therapy. We decided to resect the thymus by vldeo-assisted thoracoscopy to prevent the ouurrence of postoperative complications, especially mediastinitis because all two cases were under tracheostomy state. We could stop the mechanical ventilator therapy on the postoperati'fe 16th day and 3rd day respect- ively and they were recovered without mediastinitis. So we concluded that video-assisted thoracoscopic thymectomy is a good alternative surgical method for myasthenia gratis patients with tracheostomy.

요즘 비만은 대사성증후군의 하나로, 질병으로 인식되고 있다. 그러한 이유는 비만한 사람이 의학적으로 뿐 아니라, 사회적, 정신적으로도 장애를 일으키기 때문이다. 비만과 관련된 질환으로는 제2형 당뇨병, 고혈압, 뇌졸증, 심장질환, 고지혈증, 골관절염, 위장관질환, 담낭질환, 수면무호흡증, 암, 통풍, 정서장애, 수면장애, 섭식장애, 불임이 있으며, 그 외에도 다낭성 난소증후군 등 산부인과 질환이 있다.

Background : To assess the diagnostic role of bronchoscopic lavage for the evaluation of pneumonia in intensive care unit(ICU), the results were compared to blind endobronchial specimen. Method : From September 1993 to August 1996, twenty-eight ICU patients suspected pneumonia on the basis of clinical evidence and performed bronchoscopy under the diagnostic or therapeutic purpose were studied retrospectively for the clinical findings including culture of bronchoscopic and blind endobronchial specimen. Bronchoscopic specimen was got through small amount of bronchoalveolar lavage with 20-40ml saline, one or two times on the suspected site. Results : l. Main reasons of ICU admission were respiratory and impending respiratory failure Nosocomial pneumonia was most common with 16 cases; each for community acquired and immunocompromised type with 6 cases. Diagnostic purpose of bronchoscopy was performed in 20 cases as 71 percent in total, whereas therapeutic removal of secretion in 8 cases. The complication during bronchoscopic evaluation was trivial. 2. The agreement between blind endobronchial and bronchoscopic specimen on microbial culture was only 39.3 percent. However, 2 cases each for aspergillosis and tuberculosis were diagnosed under bronchoscopic evaluation. 3 The application of mechanical ventilation occured significantly frequently in multidrug resistant pneumonia compared with other pneumonia in terms of bronchoscopic specimen. 4. The application of mechanical ventilation was significantly common in nosocomial pneurmonia compared with other types of pneumonia. Conclusion : The selective bronchoalveolar lavage and therapeutic removal of bronchial secretion with bronchoscopy in ICU patient accompanying pneumonia is a very useful tool with safety. The multidrug resistant pneumonia or nosocomial pneumonia could be closely associated with the use of mechanical ventilation.

Sleep plays an important role in maintaining overall human health. There is increasing interest regarding the impact of sleep related disorders on metabolic diseases. Obstructive sleep apnea (OSA) is a common health problem, and in the last decade, the emergence of increasing obesity rates has further led to a remarkable increase in the prevalence of OSA, along with more prominent metabolic diseases. Obesity is the strongest risk factor for OSA. However, OSA is also known to cause obesity, suggesting an interaction between OSA and obesity. Although the underlying mechanisms leading to OSA-induced metabolic diseases are probably multi-factorial and are yet to be fully elucidated, the activation of inflammation and oxidative stress and the dysregulation of appetite-regulating hormones have emerged as important pathophysiological components of metabolic dysfunction and obesity observed in patients with OSA. Here, we will review the current state of research regarding the association of OSA with metabolic diseases and the possible pathophysiological mechanisms by which OSA could lead to such diseases. This will enhance our understanding of the potential interactions between OSA and obesity and between OSA and metabolic dysfunction.

In order to inquire the most effective management of increased intracranial pressure(ICP), mannitol, steroid and hyperventilation were used in rabbits after ligation or non-ligation of the carotid artery. Mannitol was more effective than steroid and hyperventilation in the degree of the reduction of ICP. The intracranial pressure was decreased 43~45% for 25~30 minutes after injection of mannitol. Steroid was less effective than mannitol in the degree of the reduction of ICP. But the time of reduction of ICP was longer, that is, the degree of reduction was 24~60 minutes after injection of steroid. Hyperventilation is effective in the initial time only, for 10 minutes after hyperventilation. The degree of ICP reduction was 13.5~16.7% for 10 minutes after hyperventilation. The combined group, that is three kinds of mangenent were used, is the most effective treatment to reduce ICP of ICP. The degree of the reduction of ICP was 42.1~49.3% for 20 minutes, 47.7~52.5% for 30minnutes. There was no significant difference between ligation and non-ligation group.
