如果測量一個人的細胞數量，事實上只有25%是屬於人體細胞，其餘的75%均由細菌及真菌所據。2607Please respect copyright.ＰＥＮＡＮＡOzEcnz1U65
2607Please respect copyright.ＰＥＮＡＮＡO3VYkdciNA
細菌及真菌可以說是「無處不在」，它們不但寄宿於我們的皮膚外層，亦同時駐紮在我們身體內的腸道及各器官部位，與我們成呈共生關係。2607Please respect copyright.ＰＥＮＡＮＡKsvk9Y9Mfo

最近有科學家發表學術文章（Ref1)，講述位於汗腺附近的細菌就是腋下異味的其中一個元兇。2607Please respect copyright.ＰＥＮＡＮＡqntW0HR8Qh

（圖1）我們身體的肝腺大致分為兩種，外分泌汗腺(Eccrine Sweat Glands)及大汗腺2607Please respect copyright.ＰＥＮＡＮＡJJFadDZpiV
(Apocrine Sweat Glands)2607Please respect copyright.ＰＥＮＡＮＡvP7HrkbwdY
2607Please respect copyright.ＰＥＮＡＮＡ4708Ig29MY
前者接近遍佈全身，不與毛髮連接。後者主要位於腋下、乳頭及私處部位，與毛髮連接。2607Please respect copyright.ＰＥＮＡＮＡs2RCodsxGp
2607Please respect copyright.ＰＥＮＡＮＡQVuvylfYYV
外分泌汗腺的主要功能就是散發汗水幫助散熱，調節體溫。2607Please respect copyright.ＰＥＮＡＮＡm7newv7goS
2607Please respect copyright.ＰＥＮＡＮＡdbQwGErekM
而大汗腺的主要功能，到目前為止仍未能搞得清楚。2607Please respect copyright.ＰＥＮＡＮＡ1z8y97R0ZV

（圖2）下列三點為文中所找出的異味散發機制。2607Please respect copyright.ＰＥＮＡＮＡDvyfmap9FQ
2607Please respect copyright.ＰＥＮＡＮＡ9qJ9s9pQVT
1.大汗腺釋出無味物質Cys-Gly-3M3SH。2607Please respect copyright.ＰＥＮＡＮＡBOthaWzHO7
2607Please respect copyright.ＰＥＮＡＮＡfT1GG3cLYM
2.腋下某品種的葡萄球菌消化Cys-Gly-3M3SH。2607Please respect copyright.ＰＥＮＡＮＡbocSHrYruX
2607Please respect copyright.ＰＥＮＡＮＡRTfJ3QxgYi
3. 葡萄球菌消化過後，吐出帶有異味的3M3SH。2607Please respect copyright.ＰＥＮＡＮＡWZFuN2AZjX
2607Please respect copyright.ＰＥＮＡＮＡLXUpFPsV3O
換句話說，腋下的異味就是由這些細菌引致而成的。2607Please respect copyright.ＰＥＮＡＮＡ3NdfsKBypc

（圖3）為作進一步的證實，科學家利用黃金葡萄球菌作對照實驗。2607Please respect copyright.ＰＥＮＡＮＡuiaE6UcxJo
2607Please respect copyright.ＰＥＮＡＮＡrgG5RjsiIg
他們發現人葡萄球菌的近親黃金葡萄球菌並沒能夠將無味的Cys-Gly-3M3SH消化成為帶有異味的3M3SH。2607Please respect copyright.ＰＥＮＡＮＡT72F1Bb6t2
但是，當把人葡萄球菌其中一隻酵素轉移到黃金葡萄球菌後，無味的Cys-Gly-3M3SH便能夠被消化成為帶有異味的3M3SH，證實異味是由那隻酵素所致。2607Please respect copyright.ＰＥＮＡＮＡblg6Bu4mLa
2607Please respect copyright.ＰＥＮＡＮＡ2J1baqKW2u
這隻酵素一直以來並沒有被前人發現，亦即是說，只要能夠研發出抑制那隻酵素的止汗劑的話，腋下的大部份異味亦能得以除去；2607Please respect copyright.ＰＥＮＡＮＡN38rpTpv6l
2607Please respect copyright.ＰＥＮＡＮＡaSb2eFqFl1
異味的產生，基本上是由硫醇（Thioalcohol)及脂肪酸(Fatty acid)而成。此文章所談及的機制純屬與硫醇的產生有關，沒有觸及脂肪酸那一方面。2607Please respect copyright.ＰＥＮＡＮＡldCvZbuqIn
2607Please respect copyright.ＰＥＮＡＮＡ5WUWaQr5PX
而臭狐是否由這細菌引起或有份參與，文中並沒有提及。2607Please respect copyright.ＰＥＮＡＮＡac8APjQSUS
