Histopathological changes shown by a light electronic microscope. A: the normal alveolar capillary wall in the control group (original magnificationx3300). B: capillary wall thickening, II-type necrosis, lamellar body vacuolization, inflammatory cell infiltration in the LPS group (original magnification×3300). C: no obvious capillary wall thickening in the alveolar cavity and slightly swollen mitochondria in the LPS + VIP group (original magnification×3300). D: no obvious capillary wall thickening in the alveolar cavity in the LPS + VIP + GC group (original magnification×3300).
