Fig. 2From: The Wnt7b/β-catenin signaling pathway is involved in the protective action of calcitonin gene-related peptide on hyperoxia-induced lung injury in premature ratsRAC value and MDA and TAOC levels in lung tissues of premature rats under hyperoxia. a RAC values in lung tissues of premature rats exposed to 21, 40, 60 or 95% oxygen (n = 6). b Changes in lung MDA levels (nmol/g) in premature rats exposed to 21, 40, 60 or 95% oxygen for 3, 7 and 14 days. c Changes in lung TAOC level (nmol/g) in premature rats exposed to 21, 40, 60 or 95% oxygen for 3, 7 and 14 days. *p < 0.05 vs. 3 days; ▲p < 0.05 vs. 21% group for the same period of exposureBack to article page
