3,5,4′-tri-O-acetylresveratrol Ameliorates Seawater Exposure-Induced Lung Injury by Upregulating Connexin 43 Expression in Lung

Figure 2

Microscopic findings of lung tissues stained with hematoxylin-eosin (×200). (a) control group; (b) seawater drowning group: edema, hemorrhage, thickened alveolar septum, and infiltration of inflammatory cells were observed in lung samples; (c) 3,5,4′-tri-O-acetylresveratrol (50 mg/kg) group; (e) 3,5,4′-tri-O-acetylresveratrol (450 mg/kg) group. Lung injuries were significantly alleviated by 3,5,4′-tri-O-acetylresveratrol, especially high dose of 3,5,4′-tri-O-acetylresveratrol.
