title: Effect of clenbuterol on recovery of muscle mass and carcass protein content following experimental hyperthyroidism in old rats.
abstract: The beta 2-adrenoceptor agonist, clenbuterol, has hastened the recovery of skeletal muscle and carcass weights and carcass protein stores lost during experimental hyperthyroidism in 24-month-old rats. Daily injection of 6.5 micrograms T3 per 100 g body weight for 2 weeks and 4.0 micrograms for the third week caused a 17-22% reduction in total body, carcass and combined hindlimb muscle weights, and a 16-21% reduction in carcass protein stores. Feeding diet containing 10 mg clenbuterol per kg during a 3-week recovery period caused complete restoration of these parameters to euthyroid control levels while the feeding control diet did not.
