Protective effect of glutamine on intestinal injury and bacterial community in rats exposed to hypobaric hypoxia environment.

Aim: To investigate the protective effect of glutamine (Gln) on intestinal injury and the bacterial community in rats exposed to hypobaric hypoxia environment.

Methods: Sprague-Dawley rats were divided into control, hypobaric hypoxia (HH), and hypobaric hypoxia + Gln (5.0 g/kg BW·d) (HG) groups.
