    The expression and enzyme activity of creatine kinase (CK) and hexokinase (HK) in the left (LV) and right (RV) ventricles of rats adapted for 3 weeks to normobaric hypoxia (10 % O2) either continuously (CNH) or intermittently with 1-h or 16-h normoxic episode per day were analyzed. Our results shown that up-regulation of mitochondrial CK and HK isoforms may stimulate the respiratory chain and help to maintain energy homeostasis of chronically hypoxic myocardium and prevent oxidative stress
