Statistical data for vascularization analysis of lungs after hyperoxia. Control (normoxic lungs) – blue line, hyperoxic lungs – red line. A. Average number of elastin-positive blood vessels on the lung section image. B. Average number of elastin-positive blood vessels per lung tissue area. The differences between normoxia and hyperoxia values were calculated using a general linear model (SPSS). P < 0.05 is indicated as one asterisk. Error bars indicate SEM, n = 4-6. Plot interactions are described in the text.
