Subcutaneous administration of a mixed beta-agonist to young rats induced no changes in animal growth and food conversion efficiency. However, a repartitioning effect was found with increases in lean tissue and decreases in body fat. The enhancement of muscle protein deposition was attributed to a fall in protein breakdown as muscular cathepsin A activity was lower in treated rats. A reduction of muscle reduction-oxidation state is associated to those changes in protein metabolism.
对幼鼠皮下注射混合β-激动剂未引起动物生长和食物转化效率的变化。然而，发现有重新分配效应，即瘦组织增加而体脂减少。肌肉蛋白质沉积的增强归因于蛋白质分解的减少，因为经处理的大鼠肌肉组织蛋白酶A活性较低。肌肉还原-氧化状态的降低与蛋白质代谢的这些变化有关。
