Mice immunized intraperitoneally with sheep erythrocytes were treated with nickel chloride, a common particulate air pollutant. Primary antibody production in the spleen was examined using a hemolytic plaque technique. A negative linear dose-response relationship (p is less than 0.05) was observed between the logarithm of (plaques/10(6) cells) and the nickel concentration administered. Mice injected with 3.09 mug Ni2+/g body weight displayed lymphocyte function similar to that of control mice. However, injection of 9.26-12.34 mug Ni2+/g caused significant immunosupression (p is less than 0.05).
用绵羊红细胞腹腔内免疫的小鼠,用常见的颗粒状空气污染物氯化镍进行处理。使用溶血空斑技术检测脾脏中的初次抗体产生情况。在(空斑数/10⁶个细胞)的对数与所给予的镍浓度之间观察到负线性剂量反应关系(p小于0.05)。注射3.09微克Ni²⁺/克体重的小鼠表现出与对照小鼠相似的淋巴细胞功能。然而,注射9.26 - 12.34微克Ni²⁺/克体重会导致显著的免疫抑制(p小于0.05)。
