    Abstract:
    The short-term effect of the blockade of the beta-adrenergic receptors on serum lipoproteins and the plasma activities of the enzymes involved in the metabolism of the serum lipoproteins: lipoprotein lipase (LPL), hepatic lipase (HL) and lecithin: cholesterol acyltransferase (LCAT) was evaluated in ten healthy normolipemic and normotensive subjects. In the first part of the study, the first three-day period of placebo was followed by another three-day period during which propranolol (120 mg/d) was given. In the second, third, and fourth part of the study, the same schedule was used but pindolol (15 mg/d), nadolol (160 mg/d), atenolol (100 mg/d) were given respectively instead of propranolol. The four drugs induced a significant blockade of the beta-adrenergic receptors as evaluated by the measurement of the double two-step test of Master (-45%). Despite similar blockade, the effect on serum lipid concentrations depended on the type of drug: propranolol induced an increase in triglycerides and apoprotein B-concentrations and a decrease in serum high density lipoprotein cholesterol (HDL-C) and apoprotein AI-concentrations. Pindolol provoked only a slight decrease of serum HDL-C concentration. Nadolol and atenolol elicited a lowering of the same magnitude in HDL-C. Except for a possible slight increase in plasma LCAT activity on propranolol, there was no significant change in the plasma activities of LPL, HL, and LCAT during the blockade of the beta-adrenergic receptors with the drugs used.(ABSTRACT TRUNCATED AT 250 WORDS)
