A 58-year-old man described a short history of dyspnea and a preceding flu like illness with roentgenographic features of an interstitial lung disease. An open lung biopsy specimen from him showed bronchiolitis obliterans with organizing pneumonia (BOOP). Adenovirus was isolated from a throat swab. There was both clinical and radiographic improvement with supportive care. We herein report a fir...

We describe a patient with clinical, radiological and pathological features of bronchiolitis obliterans organizing pneumonia. Investigation showed that this was likely to have been a delayed consequence of inhalation of nitric acid fumes (containing nitrogen dioxide) after a fire. This case shows that thorough investigation of the aetiology is important not only in clinical management but also ...

This paper introduces a new chemically-assisted mechanical refrigeration system that combines the advantages of the vapor compression, vapor absorption, and refrigeration/solvent resorption systems. Principles of the new system are presented and the search for suitable refrigerant/solvent pairs for the system is discussed. The feasibility of the proposed system has been verified by a sample cal...

The pathological changes involved in the immunological lung diseases of the bronchiolar region are reviewed. Next, the possibility that BOOP and DPB, two diseases whose causes are presently unknown, are caused by immune responses, is discussed.

The microtubules of the mature erythrocyte of the chicken are confined to a band at the periphery. Whole-mount electron microscopy after extraction reveals that the number of microtubules in each cell is almost the same. All the microtubules can be depolymerized by incubation in the cold, and the marginal band can be quantitatively and qualitatively reformed by return to 39 degrees C. These pro...

With the increasing of the environmental concerns, carbon dioxide (CO2) as an alternative refrigerant has been investigated intensively. In this study, the heating performance of a transcritical CO2 heat pump system with a twinrotary compressor was investigated. The transcritical CO2 heat pump with gas injection was tested by varying gas injection ratio and outdoor temperature at the optimum re...

BACKGROUND Since being identified as a concept for understanding knowledge sharing, management, and creation, communities of practice (CoPs) have become increasingly popular within the health sector. The CoP concept has been used in the business sector for over 20 years, but the use of CoPs in the health sector has been limited in comparison. OBJECTIVES First, we examined how CoPs were define...

A 69-year-old female complaining of fever, cough and dyspnea was admitted to our hospital. Chest X-ray examination showed bilateral infiltration shadows that increased in spite of antibiotics therapy. Broncho-alveolar lavage fluid analysis demonstrated an increased lymphocytes with an inverted CD4/CD8 ratio. Histopathology of lung biopsy specimens showed organizing granulation tissue in the lum...

External radiotherapy following surgery for breast carcinoma may induce radiation injury to the lungs in a number of patients. Two types of injury are recognized that are temporally related to radiotherapy; an acute pneumonitis-like illness and fibrosis, with abnormalities confined to the radiation port (1). However, the spectrum of radiotherapy-induced sequelae may be more diverse. Two patient...
