| 摘 要： | 采用毒性实验的方法 ,研究了蒽对黑鱼君几种组织的超氧化物歧化酶活性的影响。结果表明 :1 .不同的组织其SOD活性高低不同 ,按SOD活性由高到低的顺序依次排列为 :肝 >血清 >肾 >鳃 >肌肉 ;2 .不同的组织 ,其SOD活性对蒽的敏感性有所差异 ,按敏感性由大到小的顺序依次排列为 :血清 >肝 >鳃 >肌肉 >肾。3.不同组织的SOD活性在蒽胁迫下的变化规律不同。低浓度的蒽引起鳃、肾、肌肉组织的SOD活性升高 ,随着蒽浓度的提高 ,SOD活性又表现出抑制效应 ;而蒽对血清及肝组织的SOD活性从低到高浓度下始终呈现出抑制作用

| Abstract: | Effects of anthracene on activity of superoxide dismutase(SOD)in serum,liver,kidney,gill and muscle tissues of Sebastodes fuscescens were studied by toxic experimental methods. The results showed as follows:1.SOD activities exhibited differences among tested tissues, the order of SOD activity from high to low was liver>serum>kidney>gill>muscle. 2.The senstivity of SOD to anthracene also exhibited obvious differences among tested tissues, the most sensitive one to anthracene was serum SOD;the following were SOD of liver, gill and muscle tissues respectively; the tolerance of kidney SOD to anthracene was the most strongest among them. 3.The changes of SOD activity under anthracene stress were different among tested tissuse, low levels of anthracene could stimulate SOD activity of gill,kidney and muscle tissues, while the SOD activity of serum and liver always showed inhibition from low to high anthracene concentration. |
