Figure 5From: Oxidative modification of albumin in the parenchymal lung tissue of current smokers with chronic obstructive pulmonary disease Relationship between levels of carbonylated HSA and smoking status. Human lung tissue from current smokers (n = 18), ex smokers (n = 15) and non-smokers (n = 5) was homogenised. Samples were derivatised and the number of carbonyl residues measured using ELISA. The median is marked as a solid bar and expressed as carbonyl residues/HSA molecule. Data was analysed using the non-parametric Kruskal Wallis test, P < 0.05 was considered to be statistically significant.Back to article page
