    摘要:

    研究了高浓度CO2(1 000 μL/L,3 000 μL/L)引起的海洋环境pH降低对紫海胆亚氏提灯附属肌肉的呼吸耗氧、总ATP含量、乙酰胆碱含量以及肌肉收缩力的影响。140 d处理后,结果显示肌肉呼吸在3 000 μL/L组中仅为对照组(380 μL/L)的40%。总ATP含量未见显著差异。乙酰胆碱脂酶含量在高浓度CO2组有降低的趋势,但不显著。肌肉收缩力在高浓度组低于对照组。综上所述,海洋中CO2引起的pH降低对紫海胆亚氏提灯附属肌肉的生理会造成一定的影响。

    Abstract:

    The aim of the present study is to investigate the effects of high CO2 in the ocean on the physiology of Aristotle's Lantern muscle. After 140-day long-term high CO2 exposure, the muscle respiration in 3000 μL/L group decreased nearly 40% compared with control group. The ATP content was not significantly influenced by CO2. Acetylcholinesterase content in high CO2 groups decreased, but without significance. And the muscle contractile of high CO2 groups was lower than that of control group. These experiments showed that CO2 plays an important role in the muscle physiology.
