测定卵巢组织标本中抗原的含量．方法：对３３份卵巢组织标本用放射性碘标记单克隆抗体ＭｏＶ１８进行定量放射自显影测定．其中２２份为卵巢癌，７份为卵巢良性肿瘤，４份为正常卵巢组织．结果：１９份浆液性卵巢癌中，１７份有ＣＡ-ＭｏＶ１８抗原表达，含量为１．３０～５９．２８ｐｍｏｌ／ｇ组织．３份粘液性卵巢癌及１１份非恶性卵巢组织中（７份良性病变，４份正常组织）未测得ＣＡ-ＭｏＶ１８抗原．结论：ＣＡ-ＭｏＶ１８抗原在浆液性卵巢癌中有表达，其含量与肿瘤组织中标记抗体含量（％ＩＤ／ｇ）有关．关键词
Determination of ovarian tissue antigen content. Methods: Quantitative autoradiography was performed on 33 ovarian tissue specimens with radioactive iodine labeled monoclonal antibody MoV18. Among them, 22 were ovarian cancer, 7 were benign ovarian tumors and 4 were normal ovarian tissues. RESULTS: Of the 19 serous ovarian cancers, 17 had CA-MoV18 antigen expression levels ranging from 1.30 to 59.28 pmol / g tissue. CA-MoV18 antigen was not detected in 3 mucinous ovarian carcinomas and in 11 non-malignant ovarian tissues (7 benign lesions, 4 normal tissues). Conclusion: CA-MoV18 antigen is expressed in serous ovarian cancer and its content is related to the content of labeled antibody in tumor tissue (% ID / g). Key words
