Esterase D (EsD) was evaluated in 20 patients with retinoblastoma (RB). The EsD activity of the hemolysates of three unilateral cases was normal and the EsD phenotypes of their tumor cells were zero. In another three cases, including one patient with bilateral RB, the EsD was heterozygous, but the tumor cells expressed enzyme from only one of the two EsD alleles. These results provided fresh evidence for Comings' theory of tumorigenesis in which the production of sporadic nonhereditary RB has been explained. 相似文献

作者对怀疑为患鼻咽癌的339例患者血清,用间接免疫荧光法进行EB病毒VCA-IgA 抗体检测,从中选出该抗体阳性而病理诊断阴性者29例。该29例中,经第二次鼻咽部活检诊断为鼻咽癌者19例,经第三次活检诊断为鼻咽癌者2例。从而论证了检测EB病毒VCA-IgA 抗体有助于发现鼻咽癌患者。 相似文献
