在恶性肿瘤中,胃癌的危害性甚大。为了寻求新的诊断方法,江西医学院第一附属医院王崇文副教授等从1980年起开展了《胃液 IgG,IgA 研究》。近3年来,他们采用琼脂免疫单扩散试验,测定了58例正常人、79例胃癌、428例胃部良性疾患及56例胃外恶性肿瘤患者胃液中 IgG、IgA 的含量。结果表明,胃癌患者胃液 IgG 和/或 IgA 的水平显著升高,超出正常值的比率高达89.9％(71/79);而正常人、胃部良性疾患及胃外恶性肿瘤组的阳性检出率仅分别为0％(0/58)、3％(13/428)和10.3％(6/56),统计学处理显示差异十分显著。
In malignant tumors, gastric cancer is very harmful. In order to seek new diagnostic methods, Associate Professor Wang Chongwen from the First Affiliated Hospital of Jiangxi Medical College started the Gastric Fluid IgG, IgA Study from 1980. In the past three years, they used a single agar diffusion test to determine the levels of IgG and IgA in gastric fluid of 58 normal subjects, 79 cases of gastric cancer, 428 cases of benign gastric diseases, and 56 cases of extragastral malignancies. The results showed that the levels of IgG and/or IgA in gastric juice were significantly higher in patients with gastric cancer, and the rate exceeding the normal value was as high as 89.9% (71/79); however, the positive detection rate of normal people, benign gastric diseases, and extragastric malignancies was positive. Only 0% (0/58), 3% (13/428), and 10.3% (6/56), respectively, showed statistically significant differences.
