Figure 4From: Oxidative modification of albumin in the parenchymal lung tissue of current smokers with chronic obstructive pulmonary disease Relationship between smoking status and baseline levels of HSA. Human lung tissue from current smokers (n = 18), ex smokers (n = 15) and non-smokers (n = 5) was homogenised and adjusted for total protein. HSA levels were measured in lung homogenates using ELISA. The median is marked as a solid bar and expressed as μg/ml. Data was analysed using the non-parametric Kruskal Wallis test, P < 0.05 was considered to be statistically significant.Back to article page
