| 摘 要： | 测定暴露于不同汞离子质量浓度(0、0.05、0.10、0.15、0.20、0.25 mg/L)下草鱼血清和肾脏溶菌酶(LSZ)活性.在试验剂量和时间范围内结果显示,汞对草鱼血清和肾脏LSZ活性有剂量-效应关系和Hormensis现象.在0.05和0.10 mg/L浓度胁迫下,分别对血清和肾脏LSZ有激活作用;在高于0.05和0.15 mg/L浓度胁迫下分别对血清和肾脏LSZ有显著的抑制作用(P＜0.01).试验表明汞离子对草鱼具有显著的免疫毒性.

| Abstract: | In this study,the biochemistry methods were adopted to determine the activity of Lysozyme(LSZ) in serum and kidney of Grass carp(Ctenopharyngodon idella)exposed at different Hg2 concentrations for 3-week.The results showed that with in a range of exposure dosages and duration,there existed linearity relationship between dosage-response in term of Hg2 on LSZ in serum and kidney.LSZ activity in serum was significantly increased at 0.05 mg/L(P<0.05) and in kidney significantly increased at 0.10 mg/L(P<0.01).While LSZ activity in serum was markedly descended at more than 0.05 mg/L(P<0.01),and in kidney markedly decreased at 0.20 mg/L and 0.25 mg/L(P<0.05 and P<0.01).All the results indicated that Hg2 possessed obviously immuno-toxicity to Grass carp. |
