本文对522名中年期及老年期健康人血清比粘度进行了对照观察。结果表明:各年龄期血清比粘度随年龄增而逐步升高,男性中年期1.48±0.09,而老年期则1.62±0.07(P<0.01); 女性中年期为1.47±0.07,而老年期为1.60±0.02(0.05≥P<0.01);提示正常老年人,其血清比粘度随年龄增加有上升趋势。这可能与增龄性动脉壁硬化,血流缓慢,血粘度升高有关,同时年龄的递增,血清胆固醇物质亦相应的升高。这都是导致健康老年人血清比粘度升高的因素。由此认为血清比粘度不仅可作为诊断和疗效观察依据,尚可作为脑中风预报的参考指标。
In this paper, 522 middle-aged and elderly healthy people were compared the serum viscosity. The results showed that the serum specific viscosities of all ages gradually increased with age, the male middle age was 1.48 ± 0.09, while the old age was 1.62 ± 0.07 (P <0.01); the female middle age was 1.47 ± 0.07, Was 1.60 ± 0.02 (0.05≥P <0.01). It suggested that the serum specific viscosity increased with age in normal elderly. This may be related to age-related arteriosclerosis, slow blood flow, increased blood viscosity related, while increasing age, serum cholesterol substances also increased accordingly. This is all a factor that contributes to the increased serum specific viscosity of healthy older adults. Therefore, the serum specific viscosity can not only be used as a basis for the diagnosis and efficacy observation, but also as a reference indicator for stroke prognosis.
