Plasma and white blood cell ascorbic acid concentrations in patients with bronchial asthma.

Plasma cholesterol, plasma and white blood cell ascorbic acid concentrations were estimated in 30 untreated, 32 salbutamol-treated patients with bronchial asthma and in 57 normal controls. Treated and untreated asthmatics had significantly higher plasma cholesterol but lower plasma and white cell ascorbic acid levels than normal controls. A negative correlation was found between white cell ascorbic acid level and plasma cholesterol concentration in both treated and untreated asthmatics. These findings are discussed.
