[Cholesterol esterase activity in the rat aorta and liver after stimulation and blockade of beta-adrenergic receptors].

Activities of lysosomal and cytoplasmic cholesterol esterases and cholesterol content in rat blood serum, liver tissue and aorta were studied after administration of ephedrine and propranolol. The ephedrine-induced lipolytic effect was fully inhibited by propranolol. The correlation between stimulation of beta-adrenergic receptors and activation of lipolytic enzymes was found.
