Two simple spectrophotometric assays have been employed for the measurement of dopa oxidase activity and ceruloplasmin polyphenol oxidase activity in the sera from normal hamsters and hamsters bearing melanotic melanoma. Both activities were found to be augmented in tumor animals, the dopa oxidase activity much more prominently. The levels of the enzymes tested increased proportionally to the tumor mass.
已采用两种简单的分光光度法测定正常仓鼠和患有黑色素瘤的仓鼠血清中的多巴氧化酶活性和铜蓝蛋白多酚氧化酶活性。发现两种活性在肿瘤动物中均升高，多巴氧化酶活性升高更为显著。所测试的酶水平与肿瘤大小成比例增加。
