title: [Adenine nucleotide and creatine phosphate levels in rat skeletal muscles and myocardium in myorelaxation].
abstract: The content of adenylic system components and creatine phosphate was determined in skeletal muscles and myocardium after intraperitoneal injection and short-term action of myorelaxin and arduan. The injected myorelaxin causes no significant changes in macroergic phosphates in skeletal muscles, whereas arduan lowers the ATP amount by 39%. The both myorelaxants have the same effect on the adenylic system components of the myocardium: they lower significantly the level of ATP and enhance that of ADP and AMP. Different variational tendences of variation in the content of creatine phosphate in skeletal muscles (a certain rise) and in the myocardium (a decrease more than by 30%) are observed.
