The aim of this study was to investigate the diffusion lung capacity in patients with untreated hypertension. For this purpose, a total of 30 cases and 30 controls were included in the present study, which was based on several spirometry indicators in the analysis. The measurements were based on "single breath approach". The results indicated that the two groups differed in several spirometry r...

The forces expiratory volume, total lung capacity, transfer factor (diffusing capacity), and their subdivisions have been measured in 113 healthy British women aged 27 to 74 years of whom 47 were current smokers and 66 were lifetime non-smokers. The results have been analysed in terms of age, stature, mass, body fat, and smoking. In addition to their relation to stature and to age, the inspirat...

Genetically susceptible Brown Norway rats develop a chronic asthmalike syndrome after recovering from viral bronchiolitis at an early age. We hypothesized that airway closure is an important mechanism of airflow obstruction in postbronchiolitis rats. Rats were studied 8-12 wk after inoculation with Sendai virus or sterile vehicle at 3-4 wk of age. Under light pentobarbital anesthesia, rats were...

introduction: exposure to flour dust is an important risk factor in occurrence of allergic airway disorders among mill workers. the purpose of this study was to determine the prevalence of respiratory symptoms and its relation with exposure to respirable dust. materials and methods: in this study, all of 35 workers who worked in the flour producing section of three factories were chosen as case...

Introduction. The current trend away from pneumothorax is in part based on evidence indicating marked diminution in pulmonary function of the reexpanded lung after conclusion of treatment. However, this evidence is not extensive. The function of the reexpanded pneumothorax lung has been the subject of two spirometric' and three bronchospirometric investigation^.^, 4, Cournand and Richards1 firs...

AIMS In cohort studies, Type 2 diabetes mellitus has been associated with decreased forced 1 s expiratory volume and forced vital capacity. We examined if forced vital capacity, forced 1 s expiratory volume and diffusion lung capacity correlate with diabetes mellitus across different races in a clinical setting. METHODS We examined the medical records of 19,882 adults 18-97 years of age in ou...

BACKGROUND It is well established that patients with longstanding weakness of the respiratory muscles have a reduction in lung distensibility. Although this occurs in most patients without any radiographic changes suggesting parenchymal lung disease, it has been attributed to the development of microatelectasis. METHODS A high resolution computed tomographic (CT) scanner was used in eight pat...
