Compared with the LA, HA1, HA3, HA7 and HA15 group, respectively. Data are the means ± SD (n=8 per group). P<0.05 for all. SOD, superoxide dismutase; MDA, malondialdehyde. LA, low altitude; HA, MA, middle altitude; HA, high altitude; MA and HA1, 2, 7, 15, 30 represent the MA and HA subgroups at 1, 3, 7, 15 and 30 days, respectively.
