为进一步了解EB病毒与鼻咽癌的关系 ,全面综合调查鼻咽癌病人的免疫功能 ,应用PCR方法检测鼻咽癌病人组织块EB病毒DNA ,并对鼻咽癌病人血清中EB病毒 (EBV—VCA/IgA)抗体、超氧化物歧化酶 (SOD)活性、脂质过氧化物降解产物 (MDA)及数种微量元素含量进行测定 .结果 :从鼻咽癌病人鼻咽部活检组织中成功地检测出EB病毒DNA片断 .进一步证实了EB病毒与鼻咽癌的发生有密切关系 .并对鼻咽癌病人血清VCA/IgA ,SOD ,MDA及数种微量元素进行对比观测及综合研究 ,为鼻咽癌的诊断、治疗及预后评估等 ,提供了可靠的依据 .
To further understand the relationship between Epstein-Barr virus and nasopharyngeal carcinoma, to comprehensively investigate the immune function of patients with nasopharyngeal carcinoma, Epstein-Barr virus DNA was detected by PCR in tissue sections of patients with nasopharyngeal carcinoma. EBV- VCA / IgA antibody, SOD activity, lipid peroxidation (MDA) and trace elements were measured.Results: The nasopharyngeal biopsies from patients with nasopharyngeal carcinoma successfully Detected Epstein-Barr virus DNA fragments further confirmed the Epstein-Barr virus and nasopharyngeal carcinoma are closely related to the occurrence of nasopharyngeal carcinoma and serum VCA / IgA, SOD, MDA and trace elements in a variety of comparative studies and comprehensive study for the nose Pharyngeal cancer diagnosis, treatment and prognosis assessment, provide a reliable basis.
