【摘要】 本文通过Cd²⁺对白鲢外周血红细胞微核率影响的研究,提供了如下事实: Cd²⁺是一种诱变剂,它能诱发血细胞产生微核,且微核随剂量、致毒时间而递增;Cd²⁺能诱发血细胞进行不正常分裂,从而产生了多种多样的微核形式。鱼类外周血红细胞微核测定技术迅速、灵敏、诱发处理技术也十分简单,可成为水环境重金属污染的一项新的生物监测技术。更多还原

【Abstract】 The paper deals with the change of Micronuclei rate in erythrocytes in peripheric blood from silver carp poisoned by cadmium. Cadmium seems to act as a mutagen which the occurrence of micronuclei in the erythro-blast of silver carp. The number of micronuclei is increased with the treatment time and the dose of poison. The irragular division of erythroblast can be induced by cadmium, thus resulting in the different types of micronuclei. The technique determinating micronuclei rate in erythroblast in peripheric blood of fish is more sensitive and simple and it will take much less time than other method. Therefore, it can become a new biological monitoring technique for the heavy metals pollution in water errironment.更多还原
