High altitude exposure reduces bronchial responsiveness to hypo-osmolar aerosol in lowland asthmatics.
It is well-known that many patients with asthma undergo clinical improvement during a stay at high altitude. At high altitude, the atmospheric and climatic conditions (such as hypoxia, cold and dry air inhalation) could modify the bronchial responsiveness in asthmatics. Our study was designed to assess the difference in bronchial responsiveness to hypotonic aerosol between sea level and high al...
متن کاملLevomepromazine (Nozinan) reduces nonspecific bronchial hyperreactivity in asthmatics.
Ten patients with bronchial asthma were challenged with histamine before and after receiving saline and active drug (levomepromazine or antazoline) (a total of six challenges). The antihistaminic effect of levomepromazine (25 mg) was found to be comparable to that of antazoline (100 mg), evaluated from skin prick tests. Prechallenge forced expiratory volume in one second (FEV1) was found to be ...
متن کاملEffect of beclomethasone dipropionate on the bronchial responsiveness to propranolol in asthmatics.
The effect of four weeks of treatment with beclomethasone dipropionate (BDP, 500 micrograms twice daily) on the bronchial responsiveness to propranolol was examined in 16 patients with mild asthma in a placebo-controlled, double-blind crossover study. Propranolol was inhaled in doubling concentrations and the results were expressed as the cumulative dose producing a 20 percent fall in FEV1 (PC2...
متن کاملHydrogen Therapy Reduces Oxidative Stress-associated Risks Following Acute and Chronic Exposure to High-altitude Environment.
Low pressure, low oxygen concentration, and intense ultraviolet (UV) radiation in high-altitude environments, can cause oxidative stress which can trigger mountain sickness. A recent study demonstrated that hydrogen gas with a good permeability in biological membranes can treat various disorders by exerting its selective anti-oxidation and anti-inflammatory effects, indicating that hydrogen the...
متن کاملEffects of enalapril, an ACE-inhibitor, on bronchial responsiveness in asthmatics.
To assess the effects of enalapril on bronchial responsiveness, we studied ten stable asthmatics and five healthy normal volunteers. Spirometry and methacholine bronchoprovocation dose (PC20) were measured before and after oral administration of 20 mg enalapril. Significant hypotensive effect was observed in all. More than two fold (2.73) increase in bronchial responsiveness was observed in the...
