腸道發炎的時候，腸道會製造一些游離基(Reactive oxygen species)用來消滅外來的入侵者。433Please respect copyright.ＰＥＮＡＮＡCaoBeW373O
較為常見的游離基就是H2O2 ，亦即是俗稱為雙氧水的化學物。433Please respect copyright.ＰＥＮＡＮＡdnv0HEs2sk

當細菌接受過多的游離基侵襲，便會死去。433Please respect copyright.ＰＥＮＡＮＡVK4st7sJOj

（圖2）奈何道高一呎，魔高一丈，有一些細菌內含化解雙氧水的蛋白酶，更把雙氧水化解而成的氧氣供自己所用，不但不受損傷，反而加快自己的生長速度。433Please respect copyright.ＰＥＮＡＮＡ4Fw28cw6sE

（圖3）腸道發炎產生的游離基，腸道一隻名為NOX1的蛋白質有份參與製作的過程。433Please respect copyright.ＰＥＮＡＮＡV8hA7a5Qsa

當NOX1蛋白質在老鼠身上除去後，腸道發炎其間，那些擁有化解雙氧水及運用氧氣特性的細菌亦再也沒能快速滋長，奠定了腸道發炎時產生的游離基對個別細菌類別的影響。433Please respect copyright.ＰＥＮＡＮＡExUatufpdv
