Abstract Background: Workers who exposed to cotton dust are at risk of some occupational lung diseases such as byssinosis and chronic bronchitis. In general respiratory symptoms like chronic cough, sputum and dyspnea are more common in cotton dust exposed workers. With continuous exposure, progression of disease and pulmonary dysfunction will happen. In this study, we assessed the effect of co...
Introduction & Objective: passive respiratory exercises are used to prevent from accumulation of secretions, lung collapse and the incidence of ventilator-associated pneumonia in ICUs. This study is aimed to compare the effects of manual percussion and mechanical vibrations on cardiopulmonary functions of mechanically ventilated patients. Materials &Methods: This randomized crossover clinical...
pulmonary hypertension (ph) is an important cause of heart failure in chronic obstructive pulmonary disease (copd). the pro brain natriuretic peptide n-terminal (nt-probnp) has been suggested as a noninvasive marker to evaluate ventricular function. however, there is no evidence to support the use of nt-probnp in monitoring the benefits of vasodilators in copd induced ph. thus, we used nt-probn...
Background: Vitamin D (Vit D) is linked to various conditions including musculoskeletal, metabolic and cardiopulmonary diseases. However, it is not clear whether correction of vit D deficiency exerts any beneficial effect in patients with pulmonary hypertension. Methods: This study was a prospective uncontrolled longitudinal study. Patients with pulmonary hypertension and vit D d...
pulmonary arteriovenous malformations are rare clinical entities thai are associated with right to left shunts, and are often clinically presented by the triad of dyspnea, cyanosis, and digital clubbing. currently, transcatheter embolization of fistula is gaining increasing popularity as the superior therapeutic option. in certain situations, however, surgery is preferred. two cases of direct p...
Background and purpose: Hypothyroidism is one of the most common diseases in endocrinology Thyroid hormone deficiency effects on nerve and muscle fibers, pulmonary system and alveolar ventilation. The aim of this study was to evaluate the effect of Levothyroxine therapy on pulmonary function in hypothyroidism patients in Imam Hospital. Materials and methods: This study was performed on 50 ...
the process of bronchial tissue repair/remodeling depends on balance between production and degradation achieves the regulation of extracellular matrix turnover. we designed this study to evaluate relation between transforming growth factor β1 (tgfβ1) and tissue inhibitory of metaloproteinase 2 (timp2) as two main tissue mediators on activity and reversibility of asthma and chronic obstructive ...

The pro brain natriuretic peptide N-terminal (NT-proBNP) has been suggested as a noninvasive marker to evaluate ventricular function. However, there is no evidence to support the use of NT-proBNP in monitoring the benefits of vasodilators in COPD induced PH. Thus, we used NT-proBN...
Purpose: The aim of this study is to evaluate the effects of formaldehyde vapor on eyes, nose and skin and pulmonary function of medical students, as well as, indoor concentration of formaldehyde (FA) vapor in dissection laboratory. Materials and Methods: One hundred sixty five (165) medical students were selected randomly. Students were excluded if they had had history of smoking, or any condi...
