Immunohistochemical staining for VEGF. A Representative photographs of immunohistochemical staining for VEGF in the fetal and neonatal rat lung. The brownish areas indicate where VEGF 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 VEGF in the lung tissue. Comparing intrauterine infection group with control, VEGF expression of lung tissue was significantly decreased in the fetal rats from E17 to P3. *P < 0.05; **P < 0.01, vs. control group
