Logarithm of the relative expression of interleukin-1-beta mRNA and GAPDH obtained by Northern blotting in the nondependent and the dependent regions of the left lung. Error bars represent mean and 95% confidence interval (CI). C, control group; GAPDH, glyceraldehyde-3-phosphate dehydrogenase; HVLP-P, high volume-low positive end-expiratory pressure, prone; HVLP-S, high volume-low positive end-expiratory pressure, supine; logIL1: logarithmic transformation of the expression of IL-1β mRNA normalized by GAPDH mRNA; LVHP-S, low volume-high positive end-expiratory pressure, supine; OA, oleic acid injury, no ventilation.
