镉对鲤鱼磷酸酶活性的影响

Effects of Cadmium on Activity of Common Carp Phosphatases

研究了重金属镉对鲤鱼肾脏、肝胰脏、肠、血液等组织酸性磷酸酶(ACP)和碱性磷酸酶(AKP)活性的影响。结果表明,受水中16mg/L镉影响,肝胰脏的ACP活性显著升高;肾脏的ACP活性在32mg/L组显著降低;血液的ACP活性在16mg/L、32mg/L组均显著降低;肠道的ACP活性在8mg/L、16mg/L、32mg/L 3种浓度下影响均不明显。肾脏、肠道的AKP活性在16mg/L组显著降低,在32mg/L组极显著降低。体外试验表明,镉能直接抑制AKP的活性,而对ACP不产生直接影响。

The activities of ACP and AKP in nephrectomy showed obvious decrease at 32 mg/L group, the activities of ACP in hepatopancreas showed obvious increase at 16 mg/L group, and the activities of AKP in intestine showed obvious decrease at 16 mg/L and 32 mg/L groups.
