  • Particular matter is steadily increasing due to environmental factors at domestic and abroad such as industry and economy. Recently, the exposure particular matters has been reported to increase the risk not only for morbidity and mortality, but also for diseases of the respiratory system, cardiovascular system and central nervous system/neuropsychiatric disorder. Although the causes of neuropsychiatric diseases are genetic and environmental factors, it is necessary to pay more attention to environmental factors in terms of prevention. We mainly describe environmental factors that affect neuropsychiatric disorders, mainly on particular matter, which is one of harmful environmental substances. In the current study, we reviewed evidence for the presence of particular matter or particular matter related harmful air pollutants-O3, SO2, NO2/NOx, traffic related air pollution, that may represent risk factors for the development of neuropsychiatric disorder.

  • Pulmonary alveolar proteinosis is a rare disorder that is characterized by the abundant accumulation of surfactant-derived material within the alveolar spaces and distal bronchioles. Although the findings of homogenous ground-glass opacities overlaid by thickened septa, which form a "crazy paving" pattern on high-resolution computed tomography, can assist in making a diagnosis, a lung biopsy is usually required. This disorder has a variable clinical course, from spontaneous resolution to respiratory failure and death. While a whole lung lavage has been the standard treatment since the early 1960s, GM-CSF therapy has been attempted based on the recently suggested pathogenetic mechanism. We report a case of pulmonary alveolar proteinosis that resolved spontaneously after an open lung biopsy.

  • Obstructive sleep apnea is a common disorder in which respiratory flow decreases or disappears despite respiratory effort due to occlusion of the upper respiratory tract during sleep. Oxidative stress and systemic inflammatory reaction induced by the obstruction cause complications such as hypertension, coronary artery disease, and diabetes and increase cancer incidence. Furthermore, in patients with interstitial lung disease, obstructive sleep apnea has a very high prevalence and is thought to have a close pathophysiological and clinical correlation. In other words, obstructive sleep apnea could be the cause or a complication of interstitial lung disease ; when these two afflictions coexist, the prognosis of the patient is worse. In patients with interstitial lung disease with obstructive sleep apnea, CPAP treatment significantly improved sleep and quality of life, as well as improved morbidity and mortality in a recent study. Therefore, early diagnosis and treatment of obstructive sleep apnea in patients with interstitial lung disease are very important, and additional studies designed to include patients with idiopathic pulmonary fibrosis as well as patients with advanced interstitial lung disease should be performed.

  • Objective : This study's purpose was to review the clinical studies of Galgeun-tang. Method : We searched papers about Galgeun-tang using KISS, RISS, OASIS, PUBMED and J-stage. The key words we used were "Galgeuntang", "Kakkonto", "Ge gen tang", and "Pueraria Decoction". Papers not matched with inclusion criteria were excluded. Results : Until today, there have been 223 studies on Galgeun-tang. Of these, 25 studies were classified as clinical research papers. There were 4 cases of fever, 5 cases of inflammation on respiratory system, 3 cases of head, neck and shoulder disorder, 2 cases of diarrhea, 6 cases of pharmacokinetics and interaction, 5 cases of side effect. Conclusion : It can be seen that Galgeun-tang has established the basis for application to the purpose of treating fever (common cold, influenza), inflammation on respiratory system (nasal obstruction, maxillary sinus retention cyst, mucoid pseudomonas aeruginosa chronic lower respiratory tract infection), head, neck and shoulder disorder (temporomandibular disorders, shoulder stiffness, tetanus), and diarrhea. On the other hand, considering 4 cases of side effect on drug eruption, caution should be exercised when observing the progress of the patient taking Galgeun-tang.

  • Sarcoidosis is a rare systemic disorder with unknown cause that is characterized pathologically by non-caseating granuloma. The lung and mediastinal lymph nodes are almost always involved, and most patients experience acute or insidious respiratory symptom. Because sarcoidosis is an interstitial lung disorder involving the alveoli and bronchioles, the most common radiological finding is a reticularnodular lesion with lymphatic distribution. However, cavitation is quite rare. Sarcoidosis is also a major cause of hepatic granuloma in Western countries, accounting for 12% to 30% of cases. In most patients, the course of hepatic sarcoidosis is benign. However, chronic intrahepatic cholestasis or portal hypertension may develop in some patients. We report a case of sarcoidosis with cavitation and hepatic involvement.

  • Vocal cord dysfunction (VCD) is respiratory disorder characterized by paradoxical closure of the vocal cord during the respiratory cycle leading to obstructive airway symptoms. The clinical presentation of VCD is often dramatic and its misdiagnosis as asthma or exercise-induced brochospasm(EIB) has led to inappropriate treatment including high dose corticosteroids, intubation, and tracheostomy. Many VCD patients are asymptomatic at rest and require exercise challenge to elicit symptoms and vocal cord abnormalities. The "gold standard" for the diagnosis of VCD remains laryngoscopy or bronchoscopy with direct visualization of paradoxical adduction of the vocal cords. We report a case of exercise-induced Vocal cord masqueraded as exercise-induced asthma unresponsive to corticosteroids. And bronchodilator confirmed by typical bronchoscopic findings with paradoxial adduction of the vocal cords.

  • Background: Workers in slaughterhouses are exposed to a wide range of biological contaminants, such as bacteria and fungi, due to their working environment. This study aimed to assess the prevalence of respiratory disorders among workers in slaughterhouses. Methods: This study was conducted on 81 workers in slaughterhouses and 81 healthy office workers as a reference group. The American Thoracic Society standard respiratory symptoms questionnaire was used to determine the prevalence of respiratory disorders. Besides, lung function tests were conducted using a calibrated spirometer at the beginning (preshift) and at the end (postshift) of the $1^{st}$ working day. Single-stage Anderson sampler was used to measure the concentration of bioaerosols in different parts of slaughterhouses. Results: The prevalence of respiratory disorders, such as cough, productive cough, breathlessness, phlegm, and wheezing, was 3.17, 4.02, 3.07, 4.66, and 3.94 times, respectively, higher among workers in slaughterhouses compared with the reference group. Conclusion: The prevalence of respiratory disorders was significantly higher among workers in slaughterhouses. Thus, the significant reduction in the percentage predicted lung function among workers in slaughterhouses might be associated with exposure to bioaerosols in their work environment.

  • Objective : The correlation between age of onset and symptoms/severity of panic disorder has not yet been determined. The aim of this research is to determine the different clinical features of panic disorder according to the age of onset. Methods : Patients diagnosed with panic disorder were placed into two groups according to onset of age. The subjects were checked for 13 different panic symptoms presented in the DSM-IV. The investigation was also executed by severity, the anxiety sensitivity index, the scale for depression and anxiety. Results : The early onset group had significantly higher frequencies than the late onset group in the areas of "choking feeling" and "derealization or paresthesia". It was found that only "choking feeling" was statically significant as a risk factor of early onset panic disorder. Among the objective anxiety scale, the subscale of psychological anxiety was higher in the early onset group compared to the late onset group. Conclusion : "Choking feeling" was the only panic symptom that showed a significant difference in accordance with onset age. Earlier onset patients tend to experience a more frequent "choking feeling," which is related to respiratory symptoms. This could mean that earlier onset patients are more likely to have higher psychological anxiety.

  • Diffuse panbronchiollitis (DPB), a rare progressive disorder, has lately been receiving increasing attention. DPB is a disease of obscure etiology, characterized by chronic inflammation localized mainly in the region of respiratory bronchiole just distal to the terminal bronchioles. In 1983, Homma and coworkers reported 82 cases of a new clinicopathological entity, DPB, in Japan. Also DPB is a disease largely restricted geographically to Japan but the prevalence in other countries is extremely low. Histoloically, it is characterized by a suppurative bronchiolitis involving primarily the respiratory and terminal bronchioles with subsequent progression to bronchiectasis. The disease progresses rapidly and results in respiratory failure due to repeated respiratory infections. We experienced a cases of DPB accompanied with chronic maxillary sinusitis in both sinuses. Diagnosis of DPB was comfirmed by pathological results from thoracoscopic lung biopsy, typical radiological findings, clinical symptoms and pulmonary function test. After treatment with erythromycin for 6 months, the patient's condition and the typical micronodular densities on the chest radiography improved. A few case of DPB was reported in Korea. We report a case of DPB through thoracoscopic lung biopsy.

  • The development of blood ionic changes could be precipitated in acid-base disorder and subsequent treatment. As technology for detecting circulating ionized $Mg^{2+}$ (the most interesting form with respect to physiological and biological properties) is now available in veterinary clinical medicine. This present study investigated the changes of whole blood ionized $Mg^{2+}$ correlated with acute metabolic and respiratory alkalosis in rodent model. Metabolic alkalosis was induced by intravenous infusion with $NaHCO_3$ and mechanical hyperventilation was applied for respiratory alkalosis. We founded that the blood ionized $Mg^{2+}$ could be reversibly decreased by the $NaHCO_3$-induced acute metabolic alkalosis but irreversibly increased by the mechanical hyperventilation-induced respiratory acidosis and respiratory acidosis. We suggested that the potential change in blood suggested that the potential change in blood ionized $Mg^{2+}$ should be counted in treatment of acid-base disorders.
