Altered lung antioxidant status in patients with mild asthma (letter)

摘要

Lung lining fluid ascorbic acid (vitamin C) and alpha-tocopherol (vitamin E) concentrations are low in patients with mild asthma even though blood levels are normal or increased. These findings, along with the presence of increased amounts of oxidised glutathione in their airways, indicate that patients with asthma are subject to increased oxidative stress.
