Transmission electron microscopy for the lungs of neonatal rats. Legend: Transmission electron micrographs for the lungs of neonatal rats showed inflammatory cellular swelling, alveolar damage, and less surfactant-storing lamellar bodies in alveolar epithelial type II cells in response to intrauterine infection. (A) Control at P3 (× 5000, scale bar 2 μm); (B) intrauterine infection group at P3 (× 5000, scale bar 2 μm); (C) Control at P3 (× 20000, scale bar 500 nm); (D) intrauterine infection group at P3 (× 20000, scale bar 500 nm). Arrowheads mark surfactant-storing lamellar bodies
