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。2001Please respect copyright.ＰＥＮＡＮＡSrVv8oVmu4
2001Please respect copyright.ＰＥＮＡＮＡ7l6hkJPakp
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。2001Please respect copyright.ＰＥＮＡＮＡ7Swf9EkQ1E

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。2001Please respect copyright.ＰＥＮＡＮＡm5nJen5sgx

（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2001Please respect copyright.ＰＥＮＡＮＡlSXkwZfB2t

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。2001Please respect copyright.ＰＥＮＡＮＡzRSXfOsSDn
2001Please respect copyright.ＰＥＮＡＮＡPK1DNdQk3d
外分泌汗腺的主要功能就是散發汗水幫助散熱，調節體溫。2001Please respect copyright.ＰＥＮＡＮＡcCW9hO0zt0
2001Please respect copyright.ＰＥＮＡＮＡb7nO0eBuJs
而大汗腺的主要功能，到目前為止仍未能搞得清楚。2001Please respect copyright.ＰＥＮＡＮＡrPYjtPBTI5

（圖2）下列三點為文中所找出的異味散發機制。2001Please respect copyright.ＰＥＮＡＮＡ69sVDIriWE
2001Please respect copyright.ＰＥＮＡＮＡX85x8JMZC9
1.大汗腺釋出無味物質Cys-Gly-3M3SH。2001Please respect copyright.ＰＥＮＡＮＡIadumRYSzW
2001Please respect copyright.ＰＥＮＡＮＡbevj9hgq7H
2.腋下某品種的葡萄球菌消化Cys-Gly-3M3SH。2001Please respect copyright.ＰＥＮＡＮＡgm56yVGY7z
2001Please respect copyright.ＰＥＮＡＮＡKEejkdBvv6
3. 葡萄球菌消化過後，吐出帶有異味的3M3SH。2001Please respect copyright.ＰＥＮＡＮＡIdkmz9NGb3
2001Please respect copyright.ＰＥＮＡＮＡyKUvgAXZGm
換句話說，腋下的異味就是由這些細菌引致而成的。2001Please respect copyright.ＰＥＮＡＮＡhGZAHb6iLk

（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。2001Please respect copyright.ＰＥＮＡＮＡVrRkkXm55K
2001Please respect copyright.ＰＥＮＡＮＡJAOdpXpXep
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。2001Please respect copyright.ＰＥＮＡＮＡ0cJ75LDSLL
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。2001Please respect copyright.ＰＥＮＡＮＡpabjOyIb0W
2001Please respect copyright.ＰＥＮＡＮＡR8mKEzrfAC
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；2001Please respect copyright.ＰＥＮＡＮＡgZQn1w8RXX
2001Please respect copyright.ＰＥＮＡＮＡedTVbjfwqI
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。2001Please respect copyright.ＰＥＮＡＮＡKFEeAVZXte

而臭狐是否由這細菌引起或有份參與，文中並沒有提及。2001Please respect copyright.ＰＥＮＡＮＡV8ODidtGUB
