| 摘 要： | 以稀有鮈鲫为材料，研究了应激蛋白质作为生物学指标的敏感性。结果表明，在无可观察效应浓度下，经5d亚慢性胁迫暴露，以Cu2+为胁迫因子，稀有鮈鲫被诱导出约54KDa的应激蛋白质；以Zn2+为胁迫因子，稀有鮈鲫被诱导出约94KDa，67KDa和40KDa的应激蛋白质。应激蛋白质有可能成为一种生物学指标运用于生态风险性早期预警。

| Abstract: | The sensitivity of stress protein as a biomarker was researched in the project. The experiment was initiated using ＜3d old Grobiocypris rarus larvae according to subchronic toxicity test and run for 5d. Special stress proteins of approximately 54KDa or 94KDa, 67KDa and 40KDa were induced in response to Cu2+ or Zn2+ at the No Observable Effect Concentration, respectively. Compared with the conventional end points such as growth, this assay is a more sensitive and rapid indicator. Therefore, stress protein might be an useful biomarker as an early warning system in risk assessment. |
