目的研究茶多酚（ Ｔｅａ Ｐｏｌｙｐｈｅｎｏｌｓ 简称 Ｔ Ｐ） 对飞行人员球结膜微循环（ Ｂ Ｃ Ｍ） 的影响及抗氧化作用，为飞行人员选择合适的抗氧化保健药品。方法４０ 名健康疗养飞行人员随机分为 Ｔ Ｐ 组（ Ｔ Ｐ６００ ｍｇ／ｄ ， Ｐ Ｏ） ，对照组（ 服安慰剂） ，２０ ｄ 后检测。结果 Ｔ Ｐ 组红细胞超氧化物岐化酶（ Ｓ Ｏ Ｄ）活性， 全血谷光甘肽过氧化物酶（ Ｇ Ｓ Ｈ Ｐ Ｘ） 活性及血清丙二醛（ Ｍ Ｄ Ａ） 含量比值 Ｇ Ｓ Ｈ Ｐ Ｘ／ Ｍ Ｄ Ａ明显高于对照组（ Ｐ＜ ０ ．０１） ， Ｍ Ｄ Ａ 明显低于对照组（ Ｐ＜ ０ ．０５） 。 Ｔ Ｐ 组 Ｂ Ｃ Ｍ 微血管数明显增加（ Ｐ＜ ０ ．０１） ；微血流速度明显加快（ Ｐ＜ ０ ．０５） ； 轻中度红细胞聚集明显减轻（ Ｐ＜ ０ ．０５） ； 缺血区明显减少（ Ｐ＜ ０ ．０１） ； Ａ／ Ｖ 比值明显变小（ Ｐ＜ ０ ．０１） ； Ｂ Ｃ Ｍ 总积分值明显低于对照组（ Ｐ＜ ０ ．０１） 。结论 Ｔ Ｐ能提高飞行人员抗氧化能力，减少 Ｂ Ｃ Ｍ 变异，改善其微循环状态。
Objective To study the effect of tea polyphenols (Tp) on the conjunctival microcirculation (B C M) and the anti-oxidant effect of pilots, and select suitable anti-oxidant and health-care drugs for pilots. Methods Forty health-care pilots were randomly divided into T P group (P P 600 mg / d, P O) and control group (placebo) after 20 days. Results The ratio of S O D activity, G S H P X activity and MDA content in T P group were HP X / M D A was significantly higher than that of the control group (P <0.01), M D A was significantly lower than that of the control group (P <0.05). The number of B C M microvessel in T P group was significantly increased (P0.01), the micro blood flow velocity was significantly increased (P0.05), the mild and moderate erythrocyte aggregation was significantly reduced (P0.05), the ischemic area (P <0.01); the A / V ratio decreased significantly (P <0.01); and the total score of BCM was significantly lower than that of the control group (P <0.01). Conclusion T P can improve the anti-oxidant ability of pilots, reduce the B C M variation and improve the microcirculation status.
