Brief Summary
This study aims to assess the effect of inhaled corticosteroids (ICS) on airway smooth muscle (ASM) Na+, K+ pumps in patients with asthma.We wish to investigate differences in Na+, K+ pump content in healthy versus asthmatic patients, whether a reduction in airway hyper-responsiveness observed in asthmatic patients treated with ICS is attributable to an increase in Na+, K+ pump content in ASM cells and compare this in patients with non-eosinophilic asthma versus eosinophilic asthma.
