Cognitive Protective Mechanism of Crocin Pretreatment in Rat Submitted to Acute High-Altitude Hypoxia Exposure
Figure 6
Crocin pretreatment improved the antioxidant capacity in the hippocampus of rats under acute high-altitude hypoxia (). Ctr: control group, with saline. AHH: rats exposed under hypoxia for 3 days at 4200 m. LHG, MHG, HHG: rats exposed under hypoxia for 3 days at 4200 m after pretreatment by 25 mg/kg/d, 50 mg/kg/d, and 100 mg/kg/d of crocin). (a) The levels of SOD. (b) The levels of GSHPx. (c) The levels of MDA. (d) The levels of GSH. (e) The levels of GSSG. (f) The GSH/GSSG ratio. # versus Ctr, versus AHH, ■ versus Ctr, △ versus HLG, and ▲ versus HMG.
