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

Table 1 Effects of glutamine treatment on visceral indices (mg/g) in experimental rats

Group	Heart	Liver	Kidney	Lung	Spleen
Control	3.900 ± 0.173	28.330 ± 0.513	3.933 ± 0.240	5.433 ± 0.267	2.933 ± 0.117
HH	4.800 ± 0.000b	34.290 ± 0.751b	8.200 ± 0.307b	9.257 ± 0.281d	2.583 ± 0.175a
HG	4.729 ± 0.000	32.960 ± 0.909	6.600 ± 0.860e	8.814 ± 0.451	2.650 ± 0.140

The cardiac, hepatic, renal, and lung indices in SD rats in the HH group were increased compared to the control group, but the spleen index in the HH group decreased. The visceral indices in the HG group had no obvious differences compared to the HH group.

^aP < 0.05,

^bP < 0.01,

^dP < 0.001 vs Control;

^eP < 0.05 vs HH. Values are expressed as mean ± SEM (n = 7, each). Gln: Glutamine; Control: Control group; HH: Hypobaric hypoxia group; HG: Hypobaric hypoxia plus Gln group.
