丙型肝炎病毒（HCV）E2／NS1相对保守区多肽抗原在检？…

目的 研究（ＨＣＶ）Ｅ２／ＮＳ１相对保守区多肽抗原在检测抗－ＨＣＶ中的意义。方法 利用ＨＣＶＥ２／ＮＳ１基因编码的膜区糖蛋白合成Ｅ２／ＮＳ１相对保守区多肽抗原，建立酶免疫试验（ＥＩＡ），对９６例ＨＣＶ感染者及４０例正常献血员进行ＨＣＶＥ２／ＮＳ１抗体的检测，同时平行检测ＨＣＶＲＮＡ肝炎为１３．５５％，慢性丙型肝炎为２５．０４％，无症状感染者为２．０８％；正常献血员中发现３例抗ＨＣＶＥ２／ＮＳ１抗体

Significance of polypeptide antigen of HCVE2/NS1 relative conservation region in detection of anti-HCV]

OBJECTIVE: In order to study the significance of HCVE2/NS1 relative conservation region antigen. METHODS: EIA was established with HCVE2/NS1 relative conservation polypeptide antigen, as well as serum HCV RNA and ALT in patients with HCV infection. RESULTS: The positive rate of 96 cases patients who were infected by HCV is 41.67%, acute 13.55% and chronic 25.04%, and we found that there were 3 cases weak positive in 40 healths; Agreement rate is 62.5% in 40 cases of the positive of anti-E2/NS1 in sera with HCVRNA, and they have relation. In ALT level in sera, acute infection of HCV is higher than chronic (P < 0.05). CONCLUSION: There are virus necleic acid in sera when anti-HCVE2/NS1 appearence positive; however, antibody of anti-E2/NS1 relative conservation region has the some neutralive actions, and this humor immunity may have the actions in clearing virus, but wether anti-body of anti-E2/NS1 relative conservation of HCV is or not neutralive antibody well be investigated further.
