| 摘 要： | 为了给黄尾鯝种质标准和种质鉴定提供生化遗传指标，以便合理保护和利用黄尾鯝种质资源。采用聚丙烯酰胺垂直凝胶电泳法对黄尾鲴的7种新鲜组织（肝脏、心脏、脑、肌肉、脾脏、头肾和鳃）中的苹果酸脱氢酶(MDH)、乳酸脱氢酶(LDH)、酯酶(EST)、苹果酸酶(ME)、6-磷酸葡萄糖脱氢酶(6-PGDH)、超氧化物岐化酶(SOD)共6种同工酶进行了分析，并对其同工酶位点及酶谱进行了分析。结果表明，黄尾鯝的6种同工酶在不同组织中的表达存在差异。酯酶、苹果酸酶、苹果酸脱氢酶及6-磷酸葡萄糖脱氢酶在肝脏中表达活性较强，乳酸脱氢酶在肝、脾以及头肾组织中表达活性强，超氧化物歧化酶在肝、脾脏组织中活性较强。

Six Kinds of Isozymes in Different Tissues of Xenocypris davidi |
| |
| Abstract: | To provide biochemical genetic indexes for germplasm standard and identification of Xenocypris davidi, so as to appropriately protect and utilize the resources, malate dehydrogenase (MDH), lactic dehydrogenase (LDH), esterase (EST), malic enzyme (ME), 6-phosphogluconate dehydrogenase (6-PDGH) and superoxide dismutase (SOD) from seven tissues (liver, heart, brain, muscle, spleen, kidney and gill) of Xenocypris davidi were studied by using vertical gradient polyacrylamide gel electrophoresis. Isozyme loci and zymograms were also analyzed. The results showed that the six isozymes presented tissue specificity to various degrees. The activities of EST, ME, MDH and 6-PDGH in liver were high. The activity of LDH was high in liver, spleen and kidney. The activity of SOD was high in spleen and liver. |
