Abstract
- The purpose of the present study was to clarify brain monoamine metabolism during two different conditions of acute stress by quantifying changes in the brain of neonatal chicks exposed to either restraint with isolation, or fasting stress. 2. Under restraint with isolation-induced stress, dopaminergic metabolism was clearly stimulated. 3. During fasting stress, dopaminergic activity, serotonergic and norepinephrinergic metabolisms were stimulated. 4. It was concluded that brain monoamine metabolism of chicks is differentially affected by stressors.
摘要
本研究旨在通过定量分析暴露于束缚隔离或禁食应激的新生小鸡脑内的变化，阐明急性应激时脑单胺代谢的变化。
在束缚隔离诱导的应激下，多巴胺能代谢明显受到刺激。
在禁食应激期间，多巴胺能、5-羟色胺能和去甲肾上腺素能代谢被刺激。
研究结论表明，应激对小鸡脑内单胺代谢的影响存在差异。
