Abstract
In anaesthetized cats, stimulation of the lumbar sympathetic trunk inconsistently elicited small increases in the contraction of fatigued Peroneus Longus muscles (Orbeli phenomenon). Facilitation of this anti-fatigue effect was regularly observed following close intra-arterial injection of isoprenaline, a beta-adrenergic agonist. Injection of the drug by itself exerted a marked anti-fatigue effect on muscle contraction.
摘要
在麻醉猫身上，刺激腰交感干时，腓骨长肌疲劳收缩的增加并不一致（奥尔别利现象）。在动脉内近距离注射β-肾上腺素能激动剂异丙肾上腺素后，这种抗疲劳效应通常会得到增强。单独注射该药物对肌肉收缩有明显的抗疲劳作用。
