Increased hydrogen peroxide and thiobarbituric acid-reactive products in expired breath condensate of asthmatic patients.
Symptoms of bronchial asthma are a manifestation of airway inflammation. Circulatory leucocytes (predominantly eosinophils, mast cells and neutrophils), release inflammatory mediators, including reactive oxygen species, i.e. superoxide anion which is dismutated to hydrogen peroxide (H2O2). Neutrophils from asthmatics generate greater amounts of these species than those of healthy subjects. Some...
متن کاملFluorometric analysis of 2-thiobarbituric acid reactive substances in turkey.
Three experiments were conducted to develop a sensitive and reliable fluorometric thiobarbituric acid (TBA) reactive substances (TBARS) method to determine lipid oxidation products in meat. The first study was conducted to find the optimum sample preparation conditions for meat in the fluorometric method. The second study was to compare the original and the modified methods by using meat and bl...

متن کامل792Predictors of viral pneumonia in patients with community-acquired pneumonia
BACKGROUND Viruses are increasingly recognized as major causes of community-acquired pneumonia (CAP). Few studies have investigated the clinical predictors of viral pneumonia, and the results have been inconsistent. In this study, the clinical predictors of viral pneumonia were investigated in terms of their utility as indicators for viral pneumonia in patients with CAP. METHODS Adult patient...
