摘要
本文研究了水环境急性低氧胁迫对卵形鲳鲹Trachinotus ovatus选育群体血液生化指标的影响。实验设计了急性低氧试验组和对照组,每组3个平行。结果显示,急性低氧胁迫后选育群体的血清离子含量与对照组相比都有不同程度的升高,其中钠、氯、钙浓度与对照组相比差异显著(p<0.05),铁浓度极显著高于对照组(p<0.01);血清蛋白、尿酸、肌酐、血脂、血糖等指标的差异较大,其中尿酸、肌酐极显著高于对照组(p<0.01),总蛋白、总胆固醇显著低于对照组(p<0.05);血清中肌酸激酶含量极显著高于对照组(p<0.01),肌酸激酶同工酶显著高于对照组(p<0.05),γ-谷氨酰转肽酶含量显著低于对照组(p<0.05);其他指标均有不同程度的升高或降低,但差异不显著。研究表明,急性低氧胁迫造成卵形鲳鲹鳃、肾、心脏和肝脏损伤,免疫力下降。
This study dealt with the influence of acute hypoxia stress on blood biochemical indices in selective group of Wrachinotus owatus. Two experiment groups were established in terms of acute hypoxia stress group and control in triplicate for each. The results showed that after acute hypoxia stress ionic components in serum in selective group increased to varying degrees comparing with the control group. Sodium, chloride and calcium concentrations were significantly different （p〈0.05） from the control group,and level of iron was greatly higher than that in control group（p〈0.01）. There were significant differences between two groups in terms of serum protein, uric acid, creatinine,blood fat and blood glucose, with extreme significant higher in creatinine and uric acid contents （p〈 0.01） ,and significant lower in total protein and total cholesterol than that in control（p〈0.05）. Extreme signifi- cant higher in serum creatine kinase（p〈0.01）,significant higher in creatine kinase isoenzyme（p（0. 05）, and sig- nificant lower in γ-glutamyltranspeptidase were found than that in control （p〈0. 05）. Other indexes increased or decreased to varying degrees with no significantly difference. Above research indicated that acute hypoxia stress re- suited in damage in gill, kidney, heart and liver, as well as weak immunity in fish.
