高劑量維他命C 可以緩解癌症? - 抗癌

不建議貿然自行到醫美診所施打...

下列網址為日本癌症診所針對超高濃度維他命C輔助癌症治療之說明(該網頁倒數第二段)
http://www.ikebukuroclinic.jp/meneki/menu/index.html#no07

從一些漢字跟數字看來

ビタミンCの血中濃度を350mg/dl～400mg/dlまで上げることにより
如果去醫美診所施打是否可讓血中維他命C濃度達到此一水準？
日本治療是每次都會檢查血中濃度

ペースの目安は、初めの半年間は、1週間に2回 → 半年後～週に1回
開始から2年目は、月に2回 → その後は、月に1回
針對癌症治療也絕對不是要打就打
還是要有相關治療經驗來安排施打的時間和劑量

必要検査項目
1.初回のみ、腎機能検査＋ビタミンC血中濃度検査
2.初回のみ、G6PD検査（G6PD欠損症の場合、溶血の危険性がある）
3.次回より点滴後に、ビタミンC血中濃度検査
（ビタミンCの血中濃度が350～450mg/dlに安定するまでは毎回測定）
高濃度的維他命C進入體內
對於腎臟代謝勢必也會造成一些負擔
日本治療前要先進行腎臟機能的檢查
以及G6PD檢查(漢字說欠缺有危險性 查了一下似乎是指蠶豆症患者)

点滴日以外は高濃度サプリメントでビタミンC濃度をある一定濃度に保つようにするこ
とが必要です
由於維他命C很容易就會隨水分排出體外
除了點滴回輸外看起來似乎也還要隨時補充維持血中一定濃度

另外
維他命C最主要的作用為抗氧化(日文中的抗酸化)
但去年初也有新聞指出過度攝取抗氧化物對於抗癌可能造成反效果

可能造成反效果的原因在於
抗氧化物能夠清除自由基
雖然一般認為自由基會導致癌症的發生
但人體內自行清除癌細胞或抗癌藥物毒殺癌細胞也都有自由基的參與
過度的抗氧化可能適得其反

因此回到文章開頭第一句話
不建議貿然自行到醫美診所施打...
還是先經過科學研究的驗證吧！
