Acute exposure to sawdust does not alter airway calibre and responsiveness to histamine in asthmatic subjects.
We investigated the effects of particles of sawdust delivered through a special device at known concentrations (close to the threshold limit value-short term exposure limit (TLV-STEL) of 10 mg.m-3) on FEV1 and PC20 in 12 asthmatic subjects free of clinical sensitization to this product. Subjects were studied over two days (day 1: exposure to sawdust; day 2: sham exposure) in random order with a...
متن کاملEffects of platelet activating factor on airway calibre, airway responsiveness, and circulating cells in asthmatic subjects.
The effects of inhaled platelet activating factor were compared with those of inhaled methacholine (control) on airway calibre, airway responsiveness to methacholine and isoprenaline, and circulating cells in eight subjects with mild, stable asthma. Platelet activating factor was given in six doses at 15 minute intervals and airway response measured as change in partial expiratory flow at 30% o...
متن کاملComparison of airway reactivity induced by histamine, methacholine, and isocapnic hyperventilation in normal and asthmatic subjects.
In an investigation of a rapid screening test for airway reactivity using isocapnic hyperventilation with room air and cold air the results of this test were compared with the airway response to histamine and methacholine challenge. Twelve non-atopic, non-smoking normal subjects and 11 subjects with stable asthma who had an FEV1 above 74% of the predicted value were studied. In the normal subje...
متن کاملEffect of regular inhaled salbutamol on airway responsiveness and airway inflammation in rhinitic non-asthmatic subjects.
BACKGROUND Regular, inhaled beta 2 agonists may increase airway responsiveness in asthmatic subjects. The mechanism is not known but may be via an increase in airway inflammation. A study was undertaken to examine the effect of regular inhaled salbutamol on airway responsiveness to methacholine and hypertonic saline, on the maximal response plateau to methacholine, and on inflammatory cells in ...

نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...
