为了进一步研究吸烟对人体的危害，本文应用日本ＳｙｓｍｅｘＦ—８００型血细胞计数仪，从健康体检的男性中随机抽样１７２人，进行红细胞计数（ＲＢＣ计数）、平均红细胞血红蛋白（ＭＣＨ）、平均红细胞体积（ＭＣＶ）的测定。观察显示９２名无症状吸烟者与８０名不吸烟者的ＲＢＣ计数、ＭＣＨ无明显差异；而无症状吸烟者较不吸烟者的ＭＣＶ有明显增大，二者有显著性差异，Ｐ＜０．０１。吸烟者ＭＣＶ的增大与吸烟指数量明显正相关，ｒ＝０．３６１９，Ｐ＜０．００１。结果提示长时期大量吸烟者导致ＭＣＶ的增大，使血液粘稠度增加，是心脑血管疾病及呼吸系统疾病发生的重要因素。
In order to further study the harm of smoking to the human body, 172 samples were randomly selected from healthy male subjects by Routine Sysmex F-800 hemocytometer. The RBC count, MCH and RBC MCV) determination. The observation showed that RBC counts of 92 asymptomatic smokers and 80 non-smokers showed no significant difference in MCH; asymptomatic smokers than non-smokers significantly increased the MCV, both significant differences, P <0. 01. The increase of smoker MCV was positively correlated with the smoking index, r = 0.3619, P <0.001. The results suggest that a large number of smokers over a long period of time lead to an increase of MCV and increase blood viscosity, which is an important factor in cardiovascular and respiratory diseases.
