| 中文摘要: |
| 为了研究γ-氨基丁酸（γ-aminobutyric acid，GABA）对鲫鱼运输应激的缓解作用，将150条鲫鱼分为5组，分别为空白对照组、试验对照组、GABA 25 mg/L 添加组、GABA 50 mg/L添加组、GABA 100mg/L 添加组，每组3次重复，运输前和运输2 h后每组每个重复取2条鱼尾静脉采血，分离血清，测定皮质醇含量和血清生化指标。结果表明，运输应激可导致鲫鱼血清皮质醇、葡萄糖、碱性磷酸酶、总蛋白、K+等指标含量显著升高，而添加GABA 对这些指标的上升水平均有显著的缓解作用。因此，GABA能够缓解应激引起的鱼类机体损伤，从而起到抗运输应激的作用。 |

| In order to study the mitigative effect of γ-amino butyric acid (GABA) on Carassius auratus under transportation stress, 150 C. auratus were randomly divided into five groups including blank control group, experimental control group and three GABA concentrations of 25 mg/L, 50 mg/L, 100 mg/L experimental groups, with three repetitions in each. The venous blood of two fishes from each repetition were collected after transportation stress 0 h and 2 h, to detect serum biochemical parameters. The results showed that serum cortisol, glucose, alkaline phosphatase, total protein and K+ levels of C. auratus significantly increased after stress, GABA had significant mitigative effects on the above parameters. The results indicated that GABA had obvious effects on anti-transportation stress. |
