我们采用单向免疫扩散法检测了 4 8例急性白血病患者 (白血病组 )的血清免疫抑制酸性蛋白 ( IAP)含量 ,并与 4 0例健康人 (对照组 )对照 ,旨在探讨其临床意义。资料与方法 :对照组 4 0例 ,年龄 2 0～ 65岁 ,其中男 2 7例 ,女 13例 ,均为体检健康者。白血病组 4 8例 ,年龄 16～ We used a one-way immunodiffusion method to detect serum immunosuppressive acidic protein (IAP) levels in 48 patients with acute leukemia (leukemia group) and compared it with 40 healthy subjects (control group) to explore its clinical significance. Materials and Methods: The control group consisted of 40 patients aged 20-65 years old, including 27 males and 13 females, all of whom were healthy. In the leukemia group of 48 patients, age 16～
