hypoxia and hypocapnia can cause broncho-constriction in human subjects, and this could have a bearing on performance at high altitude. the object of this study was to examine how pulmonary ventilatory functions during high-altitude trekking. this study is a cohort study on spirometric parameters at different altitudes. fifty six healthy male volunteers from a university student population were...
Abstract Prevalence of respiratory symptoms and lung function impairments among Darab ginning factory workers Masoud neghab , Morteza nowroozi sarjoeeye Background: Exposure to cotton dust and its bioaerosol contaminants is the major cause of byssinosis.This study was conducted to determine the prevalence of respiratory symptoms and acute and chronic ventilatory disorders among Dara...
Background & Aims of the Study: Respiratory diseases are considered as the most important occupational diseases and the absence in the workplaces. Workers in the tile and ceramic industries are exposed to high concentrations of dusts. The main aim of the present study was to evaluate the pulmonary reactions and pulmonary function tests associated with exposure to dust among workers ...
Introduction: The purpose in this study is to analyze of DVH parameters as predictors of radiation pneumonitis and investigation on the relationship between dosimetric and clinical parameters based on PFTs as response in NTCP model and therefore achieve to lung dose- response relation in breast cancer patients. Prescribed dose to treatment volumes was 50 Gy in 2.0 Gy/fractions ...
Objectives Chronic Obstructive Pulmonary Disease (COPD) is one of the most important progressive pulmonary disorders. Diaphragmatic dysfunction is an essential factor in the worsening and progression of symptoms in patients with COPD. Therefore, we investigated the effect of diaphragmatic respiratory training on some pulmonary indexes in these patients. Methods & Materials This quasi-experimen...
background the exposure to noxious agwents such as lead my cause lung disorders. objectives in the present study, pulmonary function tests and self-reported respiratory symptoms in lead exposure workers were compared with matched control subjects. materials and methods the frequency of respiratory symptoms were evaluated in a sample of 108 lead exposure workers and 100 control subjects with sim...
Introduction: IFN-γ is one of the most important cytokines in the development of chronic inflammatory diseases such as asthma and COPD. The IFN-γ promoter methylation at CpG islands could be altered by various chemical and toxic substances which may have a role in the incidence of chronic pulmonary diseases and its severity. Thereby, the present study was aimed to evaluate the effect of sulfur ...
Background and Objective: Pelvic girdle and respiratory muscles weakness and hyperglycemia are associated with reduced lung capacity. Therefore, the aim of this study was to investigate the effect of core muscles strengthening on pulmonary function in obese women with type II diabetes. Materials and Methods: The population of the research were all women with diabetes type II in District 2 o...
