[Age-related characteristics of calcium and magnesium levels in the myocardium of growing rats after pharmacologic sympathectomy].

Administration of the sympatholytics reserpine (2.5 mg/kg), ornide (5 mg/kg), dopegyt (300 mg/kg) to rats of different ages (7- and 30-day-old and 3-5-month-old) provoked inconsistent but most pronounced changes in the myocardial content of bivalent cations (calcium and magnesium) in 7- and 30-day-old species.
