作者用体外双层琼脂培养技术测定了26例由各种原因引起的中性粒细胞增多症患者循环血中集落形成细胞(CFU-C)和白细胞集落刺激活性(CSA),并与26名正常人的平均值作了比较。测定结果:患者组每10~6白细胞的CFU-C平均为71.66±11.16,每毫升血的CFU-C平均为990.54±265.61,白细胞CSA平均为62.43±8.89,均明显高于正常(P<0.05)。正常组每10~6白细胞CFU-C平均为30.68±2.35,每毫升白细胞CFU-Cl平均为195.5±16.08。以单个病人的CFU-C和CSA值与正常值的变动范围比较,并以患者组CFU-C
The authors measured the circulating blood colony forming cells (CFU-C) and leukocyte colony-stimulating activity (CSA) in 26 patients with neutrophilic polycythemia by in vitro double-layer agar culture and compared with 26 normal The average person made a comparison. The results showed that the average CFU-C per 10 ~ 6 white blood cells was 71.66 ± 11.16, the average CFU-C per milliliter blood was 990.54 ± 265.61, and the white blood cells average CSA was 62.43 ± 8.89, which were significantly higher than the normal ). In normal group, CFU-C averaged 30.68 ± 2.35 for every 10 ~ 6 white blood cells, and average CFU-Cl per milliliter white blood cells was 195.5 ± 16.08. The individual patient’s CFU-C and CSA values were compared to the normal range of variability and the patient group CFU-C
