AbstractThe present study focused on the therapeutic effects of resveratrol in a rat model of blunt chest trauma-induced acute lung injury and the potential role of endocan as a biomarker of inflammation. They were randomly divided into the following four groups (n = 7 in each group): control group (no treatment or trauma); trauma group (trauma-induced group); resveratrol group (resveratrol [0.3 mg/kg] administered via the i.p. route group); and resveratrol + trauma group (resveratrol [0.3 mg/kg] administered via the i.p. route 1 h prior to the induction of trauma At the end of the 24 h, all the experimental rats were sacrificed. Lung lobe and blood samples were collected for biochemical, histopathological, and immunohistochemical investigations. Serum endocan levels were found to be significantly higher in the travma, resveratrol, and resveratrol + trauma groups than in the control group (p < 0.001, p < 0.001, p < 0.001). Moreover, in resveratrol + trauma group, endocan showed a significant increase compared to trauma and resveratrol group (p < 0.001, p < 0.001). Serum MDA level was significantly higher in the trauma group than in the control group (p = 0.017). SOD showed a significant increase in resveratrol and resveratrol + trauma groups compared to control group (p < 0.001, p < 0.001). The present study suggested that resveratrol exerted antioxidant properties in a rat model of lung injury after blunt chest trauma. Thus, it may have therapeutic potential in cases of blunt chest trauma-induced lung injury. Serum levels of endocan were not correlated with the inflammation response. The clinical use of endocan as a biomarker of inflammation in lung injury caused by blunt chest trauma is not recommended.
