| 摘 要： | 应用透射电镜方法，研究了镉在24h内对长江华溪触心肌细胞超微结构的影响。结果表明：注射镉后0.5h，心肌细胞超微结构即出现变化，且随着时间的延长，变化渐趋明显，主要表现在细胞核和线粒体。细胞核核膜肿胀、弥散、最后解体。线粒体嵴部分解体、直至全部解体；线粒体内室部分肿胀、明显肿胀、直至高度肿胀。此外，溶酶体的数量和类型随镉处理时间的延长而增多，肌原纤维出现断裂。

| Abstract: | From March to May in 1999, by method of transmission electron microscopy (TEM), effect of cadmium on ultrastructure of myocardial cell of freshwater crab Sinopotamon yangtsekiense Bott (1967) was revealed for the first time. The results showed that the main alterations were both mitochondria and nucleus from 30 minutes to 24 hours. First of all, nuclear membrane appeared swelling. Later, nuclear membrane disintegrated were. The mitochondrial cristae partly disintegrated, fully disintegrated. In the course of time, mitochondial showed swelling and a lot of vacuolus. Besides, the numbers and types of lysosome were increased in the mean time. Myofibril broke and losed contracted function of myocardium. |
