Immunohistochemical staining for Collagen I. A Representative photographs of immunohistochemical staining for Collagen I in the fetal and neonatal rat lung. The brownish areas indicate where Collagen I is expressed (× 200). a: intrauterine infection group at E21; b: Control at E21; c: intrauterine infection group at P14; d: Control at P14. B Staining scores of Collagen I in the lung tissue. Comparing intrauterine infection group with control, Collagen I expression of lung tissue was significantly increased from E21 to P14. *P < 0.05; **P < 0.01, vs. control group
