| 摘要: |
| 探索不同真姬菇(Hypsizygus marmoreus)多糖对泥鳅(Misgurnusmize lepis)SOD,CAT,MDA在体内分布、活力及其抗病力的影响。结果表明,相对于各对照组(CK组),精多糖CPS-1处理泥鳅17 d后其肌肉SOD酶活力为14.925 U,高于其他处理组;粗多糖C-2组处理泥鳅10d后其肌肉MDA含量为O.258μmol/g,低于其他处理组;经粗多糖C-1处理泥鳅10 d后其血液CAT酶活力为2.667 U,高于其他处理组,表明SOD,CAT,MDA在泥鳅体内的分布不同,同时在一定浓度范围内,真姬菇多糖能增加泥鳅的抗氧化能力。真姬菇多糖对泥鳅抗痛力也有显著影响,以C-2组最明显,该组多糖能显著提高泥鳅的抗病力。 |

| Abstract: |
| The effect of Hypsizygus marmoreus polysaccharides on the distribution, activity and disease resitance of SOD, CAT and MDA in loach was conducted in the present paper. The results showed that: the loach SOD activity was 14.925 U with essence polysaccharide CPS-1 treatment after 17days, which was higer than other treaments; MDA activity of loach muscle was 0.258μmol/g with coarse polysaccharide C- 2 treatment for 10 days, which was lower than other treatments; CAT activity of loach muscle was 2.667 U with coarse polysaccharide C-1 treatment for 10 days, which was higher than other treatments. It is revealed that the distributations of SOD, CAT, and MDA were different in the loach, and H. marmoreus polysaccharides can enhance the antioxidity of loach. H. marmoreus polysaccharides had an effect on loach mortality, C-2 treatment was best,and the treatment can enhance the antioxidity of loach. |
