Abstract

1 The effects of selective and non-selective beta-adrenoceptor blockade upon plasma non-esterified fatty acid concentrations in the fasting state and following insulin stress have been studied in normal subjects. 2 Atenolol, propranolol and placebo were compared in a double-blind cross-over trial in eight normal subjects. 3 Atenolol and propranolol significantly lowered plasma non-esterified fatty acid concentrations by a similar degree in the fasting, non-stressed state. This finding suggests that beta1-adrenoceptors are involved in the control of basal lipolysis. 4 Following insulin-induced stress, lower plasma non-esterified fatty acid concentrations were observed with propranolol than with atenolol. This difference may be due to beta2-adrenoceptor involvement in the stress mechanisms controlling lipolysis, or to the differences in the water-lipid solubility properties of these drugs.

摘要
  1. 在正常受试者中,研究了选择性和非选择性β-肾上腺素能受体阻滞剂对空腹状态及胰岛素应激后血浆非酯化脂肪酸浓度的影响。2. 在一项双盲交叉试验中,对8名正常受试者比较了阿替洛尔、普萘洛尔和安慰剂。3. 在空腹、无应激状态下,阿替洛尔和普萘洛尔显著降低血浆非酯化脂肪酸浓度的程度相似。这一发现表明β1-肾上腺素能受体参与基础脂肪分解的控制。4. 胰岛素诱导应激后,观察到普萘洛尔组的血浆非酯化脂肪酸浓度低于阿替洛尔组。这种差异可能是由于β2-肾上腺素能受体参与控制脂肪分解的应激机制,或者是由于这些药物水脂溶性特性的差异。
