本文应用植物血凝素(PHA)皮试检测迁延性、慢性肝炎病人和正常人的细胞免疫功能,应用剂量10微克时,迁延性、慢性肝炎病人皮试反应强度是9.6±0.7毫米,正常人反应强度为15.4±0.4毫米,其差异非常显著,说明迁延性、慢性肝炎病人部分存在细胞免疫功能低下。作者认为PHA应用剂量以10微克为宜,皮试平均直径小于9毫米者属阳性低反应。它与淋巴细胞转化率比较一致,且对治疗效果及预后的估计有一定意义。
Phytohemagglutinin (PHA) skin test in patients with persistent, chronic hepatitis and normal human cellular immune function test, the application dose of 10 micrograms, patients with persistent, chronic hepatitis skin test response intensity was 9.6 ± 0.7 mm, normal Response intensity of 15.4 ± 0.4 mm, the difference was significant, indicating that part of persistent, chronic hepatitis patients with cellular immune dysfunction. The authors believe that PHA application dose of 10 micrograms is appropriate, skin test average diameter of less than 9 millimeters are positive low reaction. It is more consistent with the rate of lymphocyte transformation, and the treatment effect and prognosis of the estimates of some significance.
