摘要

本实验研究了轻度和急性降温时酶的变化。对“水源1号”海参和人工养殖海参的CAT、SOD、POD活性和MDA含量进行了分析。结果表明:(1)在温和降温条件下，“水源1号”海参和大连养殖海参的CAT活性均呈现先降低后升高的趋势，“水源1号”海参和大连养殖海参的CAT活性分别为402.78 ~ 424.32 U/mL和409.81 ~ 430.08 U/mL;“水源1号”海参和大连养殖海参的SOD和POD活性均呈现先升高后降低后升高的趋势“水源1号”海参和大连养殖海参的丙二醛含量分别为0.019 ~ 0.086 U/mL和0.014 ~ 0.069 U/mL，“水源1号”海参和大连养殖海参的丙二醛活性分别为0.000 45 ~ 0.000 89 U/mL和0.000 24 ~ 0.000 66 U/mL;“水源1号”海参和大连养殖海参的丙二醛活性先升高后降低，“水源1号”海参和大连养殖海参的丙二醛含量分别为5.83 ~ 9.79 nmol/mL和7.57 ~ 9.90 nmol/mL在急性降温条件下，“水源1号”海参和大连养殖海参的CAT、SOD和MDA活性先升高后降低，“水源1号”海参和大连养殖海参的CAT活性分别为382.51 ~ 409.71 U/mL和383.86 ~ 399.42 U/mL，“水源1号”海参和大连养殖海参的SOD活性分别为0.023 ~ 0.038 U/mL和0.025 ~ 0.035 U/mL, MDA含量分别为5.83 ~ 9.79 nmol/mL和5.57 ~ 9.90 nmol/mL“水源1号”海参和大连养殖海参的POD活性均呈现先升高后降低再升高后降低的趋势，“水源1号”海参和大连养殖海参的POD活性分别为0.000 20 ~ 0.000 70 U/mL和0.000 18 ~ 0.000 40 U/mL。(3)不同降温方式对CAT、SOD、POD活性和MDA含量的变化均有影响，“水源1号”海参的变化比大连养殖海参敏感大连养殖海参在温度上有温和和急剧下降之分。“水源1号”海参的CAT和POD活性高于大连养殖海参;MDA含量在急剧降温条件下高于温和降温条件下。这些结果表明，在不同的温度下降模式下，海参有不同的免疫反应。“水源1号”海参在低温环境下比大连养殖海参更敏感，抗氧化能力也更高。
