三种复方中草药对斑点叉尾鮰部分生化指标的影响

为研究复方中草药“鱼欢”、“肝泰乐”、“三黄粉”对斑点叉尾鮰生化指标的影响，将以上3种中草药按5g／kg饵料的比例加到饵料中，连续喂食斑点叉尾鮰7d后取样，测定血液和组织中的生化指标。结果表明：3种复方中草药均能提高血清和脾脏的SOD／MDA和cAz孙佃A比值，提高血清和脾脏的抗氧化能力；3种复方中草药均能降低头肾的SOD／MDA和CAT／MDA比值，降低其抗氧化能力。“肝泰乐”和“鱼欢”能提高鮰的抗氧化能力，“三黄粉”和“鱼欢”能提高肌肉的抗氧化能力。3种复方中草药能降低肝胰脏中AST和ALT的活力。“肝泰乐”显著降低肝胰脏的LZM活力，“鱼欢”显著降低头肾的LZM活力，而“三黄粉”则显著提高肌肉的LZM活力。3种复方中草药均能提高血液的白细胞吞噬能力，降低肝胰脏的AST和ALT活力。

Effects of Three Compound Chinese Herbal Medicines on Some Biochemical Parameters in Ictalurus punctatus

In order to test the effects of compound Chinese herbal medicine "Yuhuan","Gantaile" and "Sanhuangfen" on biochemical parameters in Ictalurus punctatus,an oral administration trial was performed.The medicines mentioned above were added to a commercial feed at 5 g/kg separately,and were administrated to the tested fish.The fish was sampled after a continuous 7-day feeding.The biochemical parameters in blood and tissues were assayed.The results show that all the medicines enhanced SOD/MDA and CAT/MDA ratio in serum and spleen.So the antioxidant capacity in serum and spleen was enhanced.All the medicines reduced the antioxidant capacity in head kidney by means of reducing SOD/MDA and CAT/MDA ratio.The "Gantaile" and "Yuhuan" enhanced the antioxidant capacity in gill,while "Sanhuangfen" and "Yuhuan" enhanced the antioxidant capacity in muscle.All the medicines reduced AST and ALT activities in hepato-pancreas.The LZM activity was significantly cut down in hepato-pancreas by "Gantaile" and in head kidney by "Yuhuan",while "Sanhuangfen" boosted LZM activity in muscle significantly.All the medicines enhanced blood leucocytes phagocytosis and reduced AST and ALT activities in hepato-pancreas.
