[The adrenergic reactions to isopropylnoradrenaline in white rats during the development of experimental hyperthyroidism].

In the experiments with white rats injected with atropin the condition of three types of physiological adrenergic reactions was studied (intravenous infusion of isopropylnoradrenaline at a rate of 2.0 micrograms/kg/min): chronotropic reaction of the heart, calorigenic and thermogenic reactions. Experimental hyperthyroidism was caused by subcutaneous injections of thriiodothyronine at a dose of 100 micrograms/kg a day.
