摘　　要：150例行髓芯减压加自体干细胞移植股骨头坏死患者按侧别分为单侧和双侧髂骨取血两组，按取血量再分为3个亚组（200、300和400ml组），并于取髂骨血前、后行单核细胞记数。单侧髂骨取血200、300和400ml组分离后单核细胞记数分别为（3．11±1．42）×10^10／L、（2．62±1．31）×10^10／L和（2．13±0．91）×10^10／L，取血400ml组单核细胞记数显著低于取血200ml组（t=5．118，P〈0．01）；双侧髂骨取血200、300和400ml组分离后单核细胞计数分别为（4．51±2．21）×10^10／L、（3．89±2．06）×10^10／L和（2．98±1．39）×10^10/L，取血400ml组单核细胞记数显著低于取血200ml组（t=6．446，P〈0．01）；双侧髂骨取血200、300和400ml分离后单核细胞浓度明显高于单侧取血，且差异有统计学意义（t=3．119，P〈0．01；t=5．544，P〈0．01；t=2．207，P〈0．05）。提示髂骨取血所分离单核细胞浓度受不同取血方式影响：双侧高于单侧；随着取血剂量增加，分离单核细胞浓度降低。One hundred and fifty femoral head necrosis patients with intramedullary decompression received autologous stem cell transplantation. The blood was taken from unilateral or bilateral iliac, in each group the volumes of blood taken were 200, 300 or 400 ml respectively. The number of mononuclear Cells was counted before and after centrifugation. The mononuclear cell count in subgroup of 200 ml, 300 ml and 400 ml taken from unilateral iliac after centrifugation was （3. 11 ± 1.42）×10^10/L, （2. 62 ± 1.31 ） ×10^10/L and（ 2. 13 ± 0.91 ） ×10^10/L. The concentration was significantly lower in subgroup of 400 ml than that of 200 ml （t = 5. 118, P 〈0. 01 ）. The mononuclear cells count in subgroup of 200 ml,300 ml and 400 ml taken from bilateral iliac was（4. 51 ±2. 21 ） ×10^10/L, （3.89 ±2. 06）×10^10/L and （2.98 ± 1.39）×10^10/L, the coneentratlon was significantly lower in subgroup of 400 ml than that of subgroup of 200 ml （t = 6. 446, P 〈 0. 01 ）. Whether 200 ml or 300 ml or 400 ml blood were taken, the mononuclear cell count in blood taken from bilateral iliac after centrlfugation was significantly higher than that from unilateral iliac （t = 3.119, P 〈 0. 01 ; t = 5. 544, P 〈 0. 01 ; t = 2. 207, P 〈 0. 05 ）. The results indicate that the concentration of isolated bone marrow mononuclear cells is higher from bilateral lilac than unilateral iliac. The concentration of isolated monocytes is reduced gradually with the increased blood volume.
