为了研究洗涤红细胞（ＷＲＣ）输注对老年性脑萎缩的治疗作用，对 ２８例老年性脑萎缩病人每次输注洗涤红细胞１００ｍｌ，２次／月，共治疗３个月，并对治疗前后病人的微循环状态，自由基代谢及自然杀伤（ＮＫ）细胞功能进行检测。结果显示，经 ＷＲＣ输注治疗后，病人微循环各项指标与治疗前均有明显改善。全血中ＳＯＤ活性明显升高，血清中ＭＤＡ含量明显降低，ＮＫ细胞活性明显提高，并与治疗前比较差异显著（Ｐ＜０．０５）。
In order to study the therapeutic effect of washing red blood cell (WRC) infusion on senile cerebral atrophy, 28 cases of senile patients with brain atrophy were infused with 100ml red blood cells per injection for 2 times a month for 3 months. Before and after treatment, Microcirculation, free radical metabolism and natural killer (NK) cell function. The results show that after WRC infusion therapy, the indicators of patients with microcirculation and treatment were significantly improved. The activity of SOD in whole blood was significantly increased, the content of MDA in serum was significantly decreased, the activity of NK cells was significantly increased, and the difference was significant compared with that before treatment (P <0.05).
