| 摘 要： | 给８只樱桃谷肉鸭静脉注β－肾上腺素能激动剂克伦特罗（ｃｌｅｎｂｕｔｅｒｏｌ简称ＣＬ）观察鸭由翅静脉血管瘘管灌注ＣＬ０．５ｍｇ对照鸭灌注生理盐水，结果ＣＬ使肉鸭血清尿酸水平下降，ＦＦＡ大幅度提高灌注后５～４８ｈ。尿酸降低了３５％～５０％，ＦＦＡ上升了３５％～１８０％，此外，ＣＬ提高了血清ＧＰＴ活性，说明β－肾上腺素能激剂ＣＬ促进了肉鸭机能脂肪的分解，并降低蛋白质的分解。

| Abstract: | Eight Cherry Valley ducks were used to investigate the acute effect of clenbuterol (CL) on uric acid and free fatty acid (FFA) concentrations as well as GPT activity in serum. CL dissolved in normal saline was infused into vein ulnaris profunda of ducks through a pre fixed cannula. Normal saline infusion served as control. The concentration of serum uric acid declined by 35% to 50% from 5 h to 48 h after CL infusion, while FFA level increased by 35% to 180% at the same period. An enhanced GPT activity was also found in CL treated ducks. The results suggested that CL enhanced the process of lipolysis and protein synthesis, and reduced protein degradation in ducks. |
