随着免疫学的进展,肿瘤的免疫诊断已成为肿瘤早期诊断的一项重大研究课题。本文比较了正常人与肿瘤患者对“SLO”皮内试验的差异,以期作为肿瘤普查的手段之一。皮内试验方法:用商品试剂“SLO”溶液0.05毫升、内含“SLO”1个结合单位,注射于前臂掌侧皮内,24小时后观察皮肤反应,测量其发红硬结范围的直径。如红肿直径>30毫米者为3~+;红肿直径在20～29毫米者为2~+;在10～19毫米者为1~+;皮肤发红范围在10～19毫米而无硬结者为1;红肿范围<9毫米为-。结果:48例正常成人“SLO”皮试中44例呈阳性反应占91.7％;4例为低阳性反应,而无一例是阴性反应。相反的在39例确诊为肿瘤的
With the progress of immunology, immune diagnosis of tumors has become a major research topic in the early diagnosis of tumors. This article compares the differences between the “SLO” intradermal tests in normal and oncology patients, with a view to serving as one of the means of cancer screening. Intracutaneous test method: 0.05 ml of commercial reagent “SLO” solution containing 1 unit of “SLO” binding unit was injected into the forearm palmar skin. The skin reaction was observed after 24 hours and the diameter of the range of redness and sclerosis was measured. Such as swelling and swelling diameter> 30 mm were 3 ~ +; red swelling in the 20 ~ 29 mm diameter 2 ~ +; 10 ~ 19 mm were 1 ~ +; redness of the skin ranged from 10 to 19 mm without induration 1; swelling range <9 mm for -. RESULTS: Forty-four cases of SLO skin test in 48 normal adults accounted for 91.7% of the cases, while 4 cases had low positive reaction, but none of them was negative. The opposite was diagnosed as tumor in 39 patients
