Eospalax cansus is a unique model of hypoxic tolerance and is a blind subterranean mole rat which lives on the loess plateau of China. This species develops multiple mechanisms to adapt the special environments. In this study,to detect the effects of intermittent hypoxic acclimatization on cardiac functions,eighteen E. cansus were randomly assigned to normoxia( N) group and chronic intermittent hypoxia( CIH) group. The results showed that,compared with the N group,CIH could significantly increase heart rate...
