BACKGROUND & OBJECTIVE At present, the diagnosis and differential diagnosis of peripheral solitary pulmonary lesions is a hot-spot in researches of thoracic imageology, and bronchial changes is the morphologic basis of peripheral solitary pulmonary nodules, especially peripheral lung cancer. This study was to investigate the value of multi-slice CT (MSCT) in evaluating bronchial changes of peri...

Changes in the radiological appearances of the hilar region of the lungs may indicate that the pulmonary blood supply is not normal. In atresia of the pulmonary valve, the pulmonary arteries may be absent, but more often they are small and may be supplied or supplemented by anomalous vessels. Then blood reaches the lungs mainly by the bronchial arteries or by other collaterals and there is litt...

Pulmonary angiosarcomas are usually secondary tumors, and only a few primary cases have been reported. Effective strategies for treating this tumor have not been established, and the prognosis of affected individuals is generally very poor. We report a case of primary angiosarcoma presenting as a hemorrhagic solitary nodule at the bifurcation of the left main bronchus, followed for two years be...

The European Community Respiratory Health Survey (ECRHS) was the first study to assess the geographical variation in asthma and allergy in adults using the same instruments and definitions. The database of the ECRHS includes information from approximately 140,000 individuals from 22 countries. The aim of this review is to summarize the results of the ECRHS to date. The ECRHS has shown that ther...

The monoclonal antibody 703D4, which binds heterogeneous nuclear ribonucleoprotein A2/B1 (hnRNP A2/B1), has been reported to detect lung cancer more than a year earlier than routine chest X-ray or cytomorphology. To explore the biological basis of this detection, we studied the expression of this antigen in the central airways of smokers with evidence of bronchial metaplasia using specimens fro...

The sphingosine 1-phosphate receptor agonist FTY720 is a novel immunomodulator that sequesters lymphocytes in secondary lymphoid organs and thereby prevents their migration to sites of inflammation. However, there is currently no information available on whether this drug affects Th1 or Th2 cell-mediated lung-inflammatory responses. The effect of FTY720 was therefore investigated in a murine ai...

the link between allergic rhinitis and asthma is well known. bronchial hyperreactivity (bhr) may be present in rhinitis. the present study was aimed to compare airway responses in patients  with rhinitis symptoms alone following exercise challenge, and to  determine relationship of two different respiratory function tests. 98 subjects with rhinitis were investigated by spirometry and impulse os...

Sixty consecutive patients with central bronchial carcinomas were studied by fibreoptic bronchoscopy. In all forceps biopsy and bronchial needle aspiration were performed, and in 54 bronchial brushings were obtained. The combination of bronchial brushings and forceps biopsy diagnosed bronchial carcinoma of a defined cell type in 80% of patients. Bronchial needle aspiration was the most effectiv...

bronchial leiomyoma is extremely rare. to date less than 60 cases have been reported in the world literature. the presented case here is a 30 year old woman who had been treated for bronchial asthma for several years. her chest radiograph showed bulluos emphysematous changes in the right lung and computer tomography scan found the tumor in the right main bronchus near carina. diagnosis was made...
