阻塞性睡眠呼吸中止（簡(jiǎn)稱(chēng)OSA）是常見(jiàn)的睡眠能失調(diào)問(wèn)題，許多報(bào)告早已指出，患者因?yàn)檠鯕獾拖?，?dǎo)致氧化壓力（oxidativestress）升高，大腦掌管記憶與學(xué)習(xí)的部位也會(huì)受到影響。但是美國(guó)*新動(dòng)物實(shí)驗(yàn)發(fā)現(xiàn)，多喝綠茶有助改善OSA導(dǎo)致的腦部缺陷。

■抗氧化與**自由基

這項(xiàng)研究的秘密是「綠茶多酚」，研究團(tuán)隊(duì)看準(zhǔn)其抗氧化與**自由基的功能，找來(lái)106只大鼠做實(shí)驗(yàn)。在14天、每天12小時(shí)的供氧控制時(shí)間內(nèi)，大鼠氧氣供應(yīng)量受到限制，以便模擬阻塞性睡眠呼吸中止「間歇性低氧」（intermittenthypoxia）的情形Morris水迷宮morris watermaze。Morris水迷宮morris water mazeMorris水迷宮morris water mazeMorris水迷宮morris water maze

研究團(tuán)隊(duì)做出「缺氧」大鼠后，將這些大鼠分成兩組，實(shí)驗(yàn)組喂食添加綠茶多酚的白開(kāi)水，對(duì)照組則僅喂喝純白開(kāi)水。Morris水迷宮morris water mazeMorris水迷宮morris water mazeMorris水迷宮morris water mazeMorris水迷宮morris water mazeMorris水迷宮morris water mazeMorris水迷宮morris water mazeMorris水迷宮morris water maze

接下來(lái)，研究團(tuán)隊(duì)設(shè)計(jì)一套神經(jīng)科學(xué)實(shí)驗(yàn)中用到的墨利斯水迷宮（Morris watermaze）裝置，藉由大鼠尋找水中隱藏平臺(tái)的表現(xiàn)，測(cè)試牠們空間記憶的能力，以及大腦海馬回功能受損情形。Morris水迷宮morris water mazeMorris水迷宮morris water mazeMorris水迷宮morris water maze

結(jié)果發(fā)現(xiàn)，喝綠茶的大鼠表現(xiàn)優(yōu)于喝白開(kāi)水的大鼠。研究主持人、美國(guó)路易斯維爾大學(xué)（University ofLuisville）教授戴維．柯佐爾（David Gozal）表示，研究結(jié)果顯示「綠茶多酚有助于減少間歇性低氧導(dǎo)致的空間記憶學(xué)習(xí)缺損?！?/span>Morris水迷宮morris water mazeMorris水迷宮morris water mazeMorris水迷宮morris water mazeMorris水迷宮morris water maze
