Intoxication by Intraperitoneal Injection or Oral Gavage Equally Potentiates Postburn Organ Damage and Inflammation

Figure 8

Histologic state of the lungs 24 hours after injury. Sham injured mice receiving i.p. (a) and gavage (b) control, or i.p. (c) and gavage (d) ethanol have normal appearing alveoli. Burn injury alone receiving i.p. (e) and gavage (f) control display an increase in alveolar wall thickness compared to sham injured animals (a–d). Intoxication by i.p. injection (g) or gavage (h) prior to burn results in further amplified alveolar wall thickness and cellularity.
