Effects of danaparoid sodium (DA) on lung histopathology score in lipopolysaccharide (LPS)-administered rats. The histological changes identified included congestion, oedema, inflammation, and haemorrhaging 12 h after the administration of LPS. White bars represent the non-injected control animals, black bars represent the animals injected with LPS, and slashed bars represent animals injected with DA and LPS. The data are expressed as the mean ± SD. *Denotes a significant difference compared with the LPS group (p < 0.05).
