Myocardial adrenergic and cholinergic receptor function in hypoxia: Correlation with 02 transport in exercise

The time course of changes in rat myocardial alpha1-and beta-adrenoceptors and of muscarinic cholinergic (M-Ach) receptor characteristics was studied parallel with the changes in exercise systemic O2 transport during a 21-day period of hypoxia (barometric pressure 380 Torr) to assess the effects of...

Description
Summary:The time course of changes in rat myocardial alpha1-and beta-adrenoceptors and of muscarinic cholinergic (M-Ach) receptor characteristics was studied parallel with the changes in exercise systemic O2 transport during a 21-day period of hypoxia (barometric pressure 380 Torr) to assess the effects of receptor modification during accliatization on maximal exercise capacity.
