[Comparative assessment of the effect of sympatholytics and beta-adrenoblockaders on carbohydrate-phosphorus metabolic indices in the myocardium of growing rats].

The sympatholyitic ornide and beta-adrenoblocking agent alpheprol were introduced intraperitoneally in single doses of 5 and 1 mg/kg, respectively to 7--30 day and 3--5-month old adult rats. The content of ATP, ADP, AMP, inorganic phosphorus glycogen and also active P32 incorporation were determined. The 7-day old rattlings are shown to be more sensitive to ornide than to alpheprol by comparison with older animals.
