β-Glucan protects against lung injury induced by abdominal aortic ischemia-reperfusion in rats.

Background: Aortic ischemia-reperfusion (IR) is an important factor in the development of postoperative acute lung injury following abdominal aortic surgery. The aim of our study was to examine the effect of β-glucan on lung injury induced by abdominal aortic IR in rats.

Material And Methods: Thirty-two Wistar-albino rats were randomized into four groups (eight per group) as follows: the control group (sham laparotomy), aortic IR (120 min ischemia and 120 min reperfusion), aortic IR + β-glucan (β-glucan 50 mg/kg/d for 10 d was administered orally before IR), and control + β-glucan.
