Figure 6From: Vitamin A deficiency alters the pulmonary parenchymal elastic modulus and elastic fiber concentration in ratsLung elastin contents were decreased in vitamin A deficiency (VAD). Lung elastin (mean ± SEM, n = 6 for each group), normalized to the dry-defatted lung weight was decreased in VAD compared to vitamin A sufficient (VAS) rats, which was not altered by retinoic acid (RA) treatment for 12 or 21 days. (*) p < 0.05, 1-way ANOVA. Student-Newman-Keuls post-hoc test.Back to article page
