Senescence-accelerated SAMP1 mice were more sensitive to the negative effect of hypobaric hypoxia than SAMR1 mice (control). Low-temperature EPR spectroscopy showed that high sensitivity of SAMP1 mice is related to the increased concentration of methemoglobin in the blood leading to hemic hypoxia. Proton magnetic relaxation study showed that the exposure of SAMP1 mice to hypoxia can cause cerebral edema.
