本文对50例脐血和母血进行了嗜中性粒细胞吞噬力的检测,结果脐血和母血分别为76.8±20％和85.7±12％,两者经统计学处理P<0.01,脐血的吞噬力明显低于母血。另对32例脐血标本中加入20％母血清,结果脐血的吞噬力从83.2％上升到91.3％,达母血吞噬力水平。本文还对结果进行了扼要的讨论,现报告如下。 一、试剂:(1)白色葡萄球菌悬液;(2)固定剂:甲醇丙酮(1:1),(3)姬姆萨和瑞氏染液;(4)肝素25～50u/ml。 二、方法:取全血4滴于小葫芦瓶中,然后加
In this paper, 50 cases of umbilical cord blood and maternal blood neutrophil phagocytosis test, the results of cord blood and maternal blood were 76.8 ± 20% and 85.7 ± 12%, both by statistical analysis of P <0.01, navel Blood swallowed significantly lower than maternal blood. The other 32 cases of umbilical cord blood samples were added 20% maternal serum, the results of umbilical cord blood phagocytosis increased from 83.2% to 91.3%, up to the level of maternal blood phagocytosis. The article also briefly discussed the results, the report is as follows. First, the reagents: (1) Staphylococcus aureus suspension; (2) fixatives: methanol acetone (1: 1), (3) Giemsa and Wright’s dye; (4) heparin 25 ~ 50u / ml. Second, methods: take 4 drops of whole blood in a small gourd bottle, and then add
