摘要:: 研究了铜绿微囊藻通过以多刺裸腹溞为媒介生物的食物链对红鲤肝和鳃组织的影响，结果表明：1）当铜绿微囊藻密度为5.0×103 cells/mL时，红鲤肝细胞的损伤表现为细胞肿大，细胞核变形，细胞质空泡化；鳃细胞的损伤程度主要表现为细胞肿大，但整个细胞形状基本完整.2）当铜绿微囊藻密度为5.0×105 cells/mL时，红鲤肝细胞的病理损伤表现为细胞形状完全消失，细胞核严重萎缩变形，部分细胞膜溶解，细胞质有凝集现象；鳃细胞病理表现为细胞肿大.3）铜绿微囊藻密度为5.0×106 cells/mL时，红鲤肝细胞中绝大部分细胞核消失，细胞质凝集呈现颗粒状；鳃细胞也出现了小部分细胞核消失和细胞质凝集现象

Abstract:: The influence of Microcystis aeruginosa on the liver and gill tissues of Cyprinus flammans through food chain in which Moina macrocopa as vector organism was studied.The results showed:1)When the density of M.aeruginosa was 5.0×103 cells/mL,the damage of liver tissue showed that most fish hepatocyte swelled,the karyon deformed,and vacuoles appeared in cytoplasm of most fish hepatocyte;the damage of gill tissue showed that the gill cell partly swelled,but the cell shape of fish gill was almost intact.2)When the density of M.aeruginosa was 5.0×105 cells/mL,the damage of liver tissue showed that the cell shape of fish hepatocyte disappeared completely,the karyon atrophied deformed seriously,the cell membranes partly dissolved,and the cytoplasm aggregated;the gill tissue damage mainly showed that the gill cell swelled,but the cell shape was almost intact.3)When the density of M.aeruginosa was 5.0×106 cells/mL,the damage of liver tissue showed that most karyon of fish hepatocyte disappeared,and that the cytoplasm was graininess;the gill tissue damage also showed the similar situation,but not as serious as that of hepatocyte
