برونکواسپاسم ناشی از ورزش یک عارضه گذرا در انسداد راههای هوایی است که در حین تمرین یا پس از آن اتفاق می افتد . معیار تشخیص eib در این مطالعه کاهش بیش از 10% در fev1 یا 15% در fef25-75% یا 25% در pef می باشد . همچنین شاخصهای تنفسی برای ارزیابی عملکرد ریوی مورد استفاده قرار می گیرند . هدف از این مطالعه مقایسه اثر یک جلسه تمرین هوازی با دوشدت مختلف روی برخی از شاخصهای اساسی عملکرد ریوی و برونکواسپ...
به این منظور تعداد 15 دانش آموز ورزشکار(فعال) با سطوح vomax (آزمون دوچرخه کارسنج استراند-رایمینگ)برابر با 58/4±63/53 میلی لیتر بر کیلوگرم و دامنه سنی 89/0±56/18 سال در آزمون هوازی با شدت بالا(آزمون آستراند روی نوار گردان) در محیط سرد(دما 65/1±58/13 درجه سانتیگراد و رطوبت نسبی 77/1±32/ 48درصد) و محیط گرم(دما 73/1±38 درجه سانتیگراد و رطوبت نسبی 52/1±07/ 48درصد) بعد از مواجه با این شرایط، فعالیت ک...
Art students are exposed to many noxious agents during their training. We studied respiratory findings in a cohort of the 117 art students in order to investigate the potential effects of these toxic agents in the art student's environment. A group of 88 medical students matched for age, sex and smoking, not exposed to known environmental pollutants were studied as controls for respiratory symp...
Respiratory symptoms and ventilatory capacity were studied in a group of 288 workers (259 women and 29 men) employed in a confectionery plant. A group of workers (96 women and 31 men) not exposed to confectionery manufacture were also studied as controls. The prevalence of chronic respiratory symptoms was higher in exposed than in control workers, being greatest for confectionery workers expose...
BACKGROUND Both air pollution and genetic variation have been shown to affect lung function. Their interaction has not been studied on a genome-wide scale to date. OBJECTIVES We aimed to identify, in an agnostic fashion, genes that modify the association between long-term air pollution exposure and annual lung function decline in an adult population-based sample. METHODS A two-stage genome-...
OBJECTIVES Reference values for lung function tests differ in samples from different countries, including values for preschoolers. The main objective of this study was to derive reference values in this population. METHODS A prospective study was conducted through a questionnaire applied to 425 preschool children aged 3 to 6 years, from schools and day-care centers in a metropolitan city in B...
Background. Foodstuff traders operating from warehouses (FTFW) are potentially exposed to dangerous rodenticides/pesticides that may have adverse effects on cardiopulmonary function. Methods. Fifty consenting male foodstuff traders, comprising 15 traders (21-63 years) operating outside warehouses and 35 FTFW (20-64 years), were randomly recruited at Ogbete Market, Enugu, in a cross-sectional ob...
