Effect of in vivo treatment with vehicle or C-peptide on lung histology at 3 h after HS/R. A: representative photomicrograph of histology showing lung architecture from a rat in the Control group (magnification ×100). B: magnified section of prior image (indicated by circle) to show alveolar architecture and blood vessel from a rat in the Control group (magnification ×400). C: representative photomicrograph of histology showing lung architecture from a rat in the HS/R+Vehicle group (magnification ×100). D: magnified section of prior image (indicated by circle) demonstrating interstitial edema and inflammatory cell infiltration from a rat in the HS/R+Vehicle group (magnification ×400). E: representative photomicrograph of histology showing lung architecture from a rat in the HS/R+C-peptide group (magnification ×100). F: magnified section of prior image (indicated by circle) demonstrating a reduction in interstitial edema and inflammatory cell infiltration from a rat in the HS/R+C-peptide group (magnification ×400).
