本文研究了口服补锌对28名健康老年人自然杀伤细胞(NKC)活性的作用。健康老年人NKC活性和血浆锌值均显著地低于健康青年人(P<0.05)。健康老年人经口服补锌(硫酸锌300mg/d,连服4w)后,与对照组比较,结果补锌组NKC活性和血浆锌值均显著地增高(P<0.05),补锌组血浆锌值与NKC活性呈显著正相关(r=0.781,P<0.01)。认为补锌可能对NKC活性起调节作用,老年人补锌可能有益于增强其免疫功能。
This article studies the effect of oral zinc supplementation on natural killer cell (NKC) activity in 28 healthy elderly. NKC activity and plasma zinc value were significantly lower in healthy elderly than in healthy young people (P <0.05). Compared with the control group, the results showed that NKC activity and plasma zinc value increased significantly in healthy elderly (P <0.05), while zinc supplementation (300 mg / d zinc sulfate, even served for 4 weeks) The value of NKC activity was positively correlated (r = 0.781, P <0.01). Zinc supplementation may play a role in regulating NKC activity, zinc supplementation may benefit the elderly to enhance their immune function.
