Many organic and nonorganic agents can cause chemical pneumonitis. Chemical pneumonitis induced by inhalation of acetic acid is a rare clinical condition. As acetic acid is a water soluble agent, it causes chemical irritation to respiratory tract and causes variable symptoms. We experienced a case of acute lung injury due to inhalation of acetic acid fume. A 56-year-old male patient was admitted due to dyspnea with vomiting for one day. After he inhaled acetic acid fume in occupational situation, he had chest tightness, chilling sense, and productive cough. Our case was good response to oxygen inhalation, antibiotics, and systemic steroids.

A 3-year-old female jaguar (Panthera onca onca) died after having 1 day history of respiratory failure. At necropsy, the pericardial sac contained large amounts of cloudy fluid enriched with fibrin. Numerous yellowish nodules, which are variable in size and often confluent, are randomly scattered throughout the myocardium. Pasteurella haemolytica was isolated from the pericardial sac and myocardium. In the lung, severe pulmonary congestion, edema and vasculities with intralesional presence of heartworm were found. Therefore the cause of death in this jaguar is believed to be due to respiratory failure following concurrent heartworm infection and bacterial pericarditis and myocarditis.

Pulmonary histiocytosis X is an idiopathic benign disease characterized by proliferation and infiltration of lung tissue by characteristic Langerhans cells and eosinophils. Pulmonary histiocytosis X is common in young male adults, and shows variable clinical characteristics. We experienced a case of pathologically proven pulmonary histiocytosis X in a 30-year-old man who visit to our hospital due to chest discomfort and cough. The chest radiograph of our patient shows right pneumothorax and characteristic multiple thin-walled cysts on the both upper lung fields. The HRCT shows multiple thin-walled cysts, a few scattered nodules in both upper and right middle lung, and right pneumothorax.

The congenital cystic adenomatoid malformation of the lung is a rare disease, and is one of the most common congenital lung diseases which require prompt surgical intervention. The prognosis depends on its tissue type, prompt diagnosis and surgical intervention. The lesion consists of enlarged, variable sized multiple cyst with overgrowth of terminal bronchioles, like hamartoma. This disease can be associated with other vascular anomalies or other congenital defect especially in type II lesion We recently experienced one case of congenital cystic adenomatoid malformation The patient was 2 months old infant who showed respiratory distress without associated anomaly. After right upper lobe lobectomy, the patient was recovered uneventfully.

Cardiovascular and respiratory responses of fish exposed to environmental hypoxia have on the subject of a number of investigations. Although relatively few species have been examined, generalized responses to ambient hypoxia include an elevation of blood pressure, increased systemic vascular resistance and bradycardia (Fritsche and Nilsson, 1990; Bushnell and Brill, 1991). The degree of bradycardia experienced by fish during hypoxia is highly variable and may depend upon the severity of the hypoxia and the rapidity with which it is imposed. (omitted)

1. The effect of variations in inspiration and expiration times on heart rate variability was studied in 78 healthy subjects (mean age $24.35{\pm}1.92$ years; 47 male) between regulated respiration group and normal respiration group as the control group. 2. The control group followed normal respiration pattern, whereas the regulated group followed three types of respiration pattern. The first pattern was long respiration(E/I ratio 1.6:1), the second pattern was short inspiration followed by long expiration (SILE), and the last pattern was long inspiration followed by short expiration(LISE). The average expiration/inspiration time ratios of SILE and LISE were 1.0 and 3.4, respectively. The respiration rate in the regulated group was approximately 10 cycles/min. 3. Respiration rate and tidal volume are respiratory variables known to modulate RSA. The results of the present study indicate that RSA can also be modulated by a third respiratory variable, the expiration/inspiratory time ratio. In this study, LF, HF, RSA, VLF is increased the most in LISE group compared to the other groups. HF and RSA increased significantly in the long respiration rate and SILE groups. However LF and VLF, which reflects the sympathetic tones, did not increase as much as the LISE group.

To evaluate the effect of air pollution on respiratory health in children, we conducted a longitudinal study in which children were asked to record their daily levels of peak expiratory flow rate using potable peak flow meter (mini-Wright) far 4 weeks. The relationship between daily PEFR and ambient air particle levels was analyzed using a mixed linear regression models including gender, age in you, weight, the presence of respiratory symptoms, and relative humidity as an extraneous variable. The daily mean concentrations of PM$\_$10/ and PM$\_$2.5/ over the study period were 64.9$\mu\textrm{g}$/㎥ and 46. l$\mu\textrm{g}$/㎥, respectively. The range of daily measured PEFR in this study was 170-481 l/min. Daily mean PEFR was regressed with the 24-hour. average PM$\_$10/ (or PM$\_$2.5/) levels, weather information such as air temperature and relative humidity, and individual characteristics including sex, weight, and respiratory symptoms. The analysis showed that the increase of air particle concentrations was negatively associated with the variability in PEFR. We estimated that the IQR increment of PM$\_$10/ or PM$\_$2.5/ were associated with 1.5 l/min (95% Confidence intervals -3.1, 0.1) and 0.8 l/min (95% Cl -1.8, 0.1) decline in PEFR. Even though this study shows negative findings on the relationship between respiratory function and air particles, it is worth noting that the findings must be interpreted cautiously because exposure measurement based on monitoring of ambient air likely results in misclassification of true exposure levels and this is the first Korean study that PM$\_$2.5/ measurement is applied as an index of air particle quality.

The purpose of this study was to examine the respiratory system health condition of dental technicians and to be of use for more successful health management and health promotion for them. The subjects in this study were 155 dental technicians who were working in North Jeolla province. Out of them, 70 dental mechanics were investigated in 1993, and 85 were surveyed in 2001. And the reports of the two groups on respiratory distress, including cough, sputum, phlegm, the notable sound of breathing, nasal discharge, coryza, shortness of breath and gasping, were compared. The findings of this study were as below: 1. The cough report rate was 24.3% in 1993 and 16.5% in 2001. There appeared approximately 7.8% decrease between the two years. The most powerful variables included working hours and age. 2. The complaint rate of sputum and phlegm was 47.1% in 1993 and 43.5% in 2001. The rate of 2001 reduced by 3.6%. Whether or not they smoked was identified as the most influential variable. 3. The report rate of shortness of breath and gasping was 7.4% in 1993 and 12.9% in 2001, and this rate showed about 1.5% increase in the latter year. The biggest variables were working hours and career. 4. The complaint rate of nasal discharge and coryza was 41.4% in 1993 and 44.7% in 2001, which showed about 3.3% increase. The largest variables were smoking and career. 5. The report rate of the notable sound of breathing and breathing in light little gasps was 12.0% in 1993 and 17.6% in 2001. There was approximately 5.6% increase, and the most powerful variables were working hours and career.

Broncholiths are defined as calcified materials that occur in a tracheobronchial tree or in a cavity communicating with that. Broncholith has variable clinical features. The therapeutic options to remove broncholiths are so variable that clinicians need to select the most safe and effective methods by mass size, mobility, and location. As yet, there is no consistent guideline removing a broncholith. We report 2 successful cases of removing a fixed broncholith by flexible bronchoscopy guided cryoadhesion. With repeated technique of thawing and freezing with cryoprobe, we could extract the fixed broncholith safely. This method is promising as a way to remove broncholith in the future.
