本文应用氨基酸自动分析仪测定了18例正常人外周血的红细胞、淋巴细胞(包括单核细胞)和粒细胞的多胺浓度。以nmol/10~9细胞为单位,其白细胞的腐胺、精脒与精胺的浓度要高出红细胞几百倍,然而淋巴细胞与多形核细胞之间则不存在显著差异,而且性别之间亦无差异。不同年龄组血细胞多胺测定发现,淋巴细胞中的精脒、精胺水平有随年龄增长而减低的趋势,而多形核细胞中的精脒、精胺则有随年龄增加而增加韵趋势,这些均可能与细胞的功能减退有关。 In this paper, 18 cases of normal human peripheral blood erythrocytes, lymphocytes (including mononuclear cells) and granulocytes polyamine concentration was measured by amino acid analyzer. The concentration of putrescine, spermidine and spermine in leucocytes was several hundred times higher than that of erythrocytes in nmol / 10-9 cells, whereas there was no significant difference between lymphocytes and polymorphonuclear cells There is no difference between. The measurement of polyamines in different age groups showed that the levels of spermidine and spermine in lymphocytes decreased with age, whereas spermidine and spermine in polymorphonuclear cells increased with the increase of age, These may be related to cell dysfunction.
