INTRODUCTION Persons with high or low body mass index (BMI), involved in clinical or mechanistic trials involving exercise testing, might estimate dyspnoea differently from persons with a normal BMI. AIMS Our objective was to investigate the relationship between BMI and dyspnoea during exercise in normal subjects with varying BMI. MATERIAL AND METHODS A total of 37 subjects undertook progre...

OBJECTIVE To test the hypothesis that macrophage migration inhibitory factor (MIF) is involved in the disease activity of systemic vasculitis. METHODS Patients with systemic vasculitis were divided into three groups based on the size of the affected vessels. Microscopic polyangiitis (MPA) was considered as small vessel vasculitis (SVV), polyarteritis nodosa as medium-sized vessel vasculitis (...

The atrial T wave (l’a) was studied by computer analysis in 171 patients with chronic obstructive pulmonary disease (COPD). They were divided into three groups according to Ta amplitude. Group 1 included 98 cases (57.6 percent) with Ta of .05 my or less, group 2, 38 cases (22.3 percent) with Ta between .06 my and .09 my, and group 3, 35 cases (20.5 percent) with Ta of .10 my or more. The mean T...

In twelve patients with severe emphysema who underwent lung volume reduction surgery (LVRS), we assessed the results of dyspnea scale, pulmonary function, 6-minute walk distance (6MD), and thoracic movement prior to and 6 months following LVRS. Postoperatively, forced expiratory volume (FEV1), maximum inspiratory mouth pressures (MIP), maximum expiratory mouth pressures (MEP), maximum voluntary...

Aim The small ruminant lentiviruses are known to cause maedi-visna (MV) and caprine arthritis - encephalitis in sheep and goats, typically affecting joints, udder, lungs, and the central nervous system. The diagnosis usually involves serology, clinical signs, immunohistochemistry, and polymerase chain reaction (PCR). In the present study, the histopathologically positive pneumonia cases of MV w...

Background: Pulmonary function tests are getting increased favour not only of industrial physiologists but also of practicing physicians. Obesity is a major health concern facing today’s society. This study has looked into a possible role of obesity in the aetiology of mortality, with decreased pulmonary functions resulting in cardiovascular disease. Methods: Pulmonary function tests (PFTs) of ...

Purpose: The purpose of this study was Comparison of pulmonary function parameters changes at different altitudes in female athletes. Methods eleven voluntary Female athletes, (age; 22.27±0.65yr), (weight; 57.00±6.31kg), (Fat%:20.81±3.2 1) (Height; 160.54± 3.7cm and vo2max: 40.65±1.00) were selected to this study on spirometric parameters. Each subject was informed consent form. Respiratory fun...

The strength of the respiratory muscles can be evaluated from static measurements (maximal inspiratory and expiratory pressures, MIP and MEP) or inferred from dynamic maneuvers (maximal voluntary ventilation, MVV). Although these data could be suitable for a number of clinical and research applications, no previous studies have provided reference values for such tests using a healthy, randomly ...

Relationship between breathlessness and hypoxic and hypercapnic ventilatory response in patients with COPD. S. Kobayashi, M. Nishimura, M. Yamomoto, Y. Akiyama, K. Miyamoto, Y. Kawamaki. ©ERS Journals Ltd 1996. ABSTRACT: The purpose of this study is to examine the relationship between breathlessness and the ventilatory response to hypercapnia or hypoxia in patients with chronic obstructive pulm...
