Effects of Adrenergic Receptor Blockade on Digitalis Intoxication in Mice

This experiment was carried out to investigate the influence of adrenergic receptor blockade. on digitalis intoxication. The effects of adrenergic alpha and beta receptor blockade on the lethal dose of digitonin were evaluated. $LD_{50}$ and dose mortality curve of digitonin in mice pretreated with dibenzylin or propranolol hydrochloride (Inderal) were obtained. All drugs were injected subcutaneously. Digitonin toxicity was significantly decreased in mice pretreated with beta·blockade compare with alpha-blockade and control groups.
