摘要
用不同浓度的HgCl2饲喂泥鳅20d,观察血红细胞的凋亡情况.结果表明:汞能诱导泥鳅红细胞的凋亡,凋亡率随Hg+剂量增大而增加,在第7天凋亡率从7%增至61.2%,光镜下实验浓度为0.8,1.0,1.2mg/L组均观察到红细胞凋亡的典型形态变化.结论:汞能诱导泥鳅红细胞凋亡.
Feed the Misgurnus anguillicadatuses different concentrations of HgCl2 for 20 days, and then observ the erythrocytes apoptosis of them, and the results turn out to be as follows： mercuric chloride could lead to apoptosis of erythrocytes in Misgurnus anguillicadatuses , and the apoptosis rate increases with the increase of dose. On the 7th day, the rate of apoptosis could increase from 7 % to 61.2%. Under the microscope, typical morphologic changes of erythrocytes are observed in group 3,4 and 5. Conclusion： Hg^2＋ can lead to erythrocytes apoptosis of Misgurnus anguillicadatusess.
