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。2650Please respect copyright.ＰＥＮＡＮＡzXfPq40X0n
2650Please respect copyright.ＰＥＮＡＮＡdUTyQvKSzo
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。2650Please respect copyright.ＰＥＮＡＮＡpGMPEfpq5b

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。2650Please respect copyright.ＰＥＮＡＮＡOWLExbvUyY

（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2650Please respect copyright.ＰＥＮＡＮＡERnZkigc2R
(Apocrine Sweat Glands)2650Please respect copyright.ＰＥＮＡＮＡebKO01bnga
2650Please respect copyright.ＰＥＮＡＮＡY0OxfXYvaJ
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。2650Please respect copyright.ＰＥＮＡＮＡ7ztIYmYbnF
2650Please respect copyright.ＰＥＮＡＮＡFVkFBUvHaG
外分泌汗腺的主要功能就是散發汗水幫助散熱，調節體溫。2650Please respect copyright.ＰＥＮＡＮＡiRbf4Gkhgp
2650Please respect copyright.ＰＥＮＡＮＡ2lrjZpMBrg
而大汗腺的主要功能，到目前為止仍未能搞得清楚。2650Please respect copyright.ＰＥＮＡＮＡ8BB7wssiGJ

（圖2）下列三點為文中所找出的異味散發機制。2650Please respect copyright.ＰＥＮＡＮＡ8nUWdRy0bd
2650Please respect copyright.ＰＥＮＡＮＡS8520fseIi
1.大汗腺釋出無味物質Cys-Gly-3M3SH。2650Please respect copyright.ＰＥＮＡＮＡJWKxfOrk2B
2650Please respect copyright.ＰＥＮＡＮＡWhoKLrrWjJ
2.腋下某品種的葡萄球菌消化Cys-Gly-3M3SH。2650Please respect copyright.ＰＥＮＡＮＡxyQuVd205g
2650Please respect copyright.ＰＥＮＡＮＡjOZo7d0Fsr
3. 葡萄球菌消化過後，吐出帶有異味的3M3SH。2650Please respect copyright.ＰＥＮＡＮＡmUwTbohOOk
2650Please respect copyright.ＰＥＮＡＮＡJ02K3LuNHQ
換句話說，腋下的異味就是由這些細菌引致而成的。2650Please respect copyright.ＰＥＮＡＮＡxAwD0kKeGN

（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。2650Please respect copyright.ＰＥＮＡＮＡ99FdJm8dHe
2650Please respect copyright.ＰＥＮＡＮＡIWapSICZsd
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。2650Please respect copyright.ＰＥＮＡＮＡ6iY2YMjHAG
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。2650Please respect copyright.ＰＥＮＡＮＡklMIzSwOMk
2650Please respect copyright.ＰＥＮＡＮＡMZCCcLdCFC
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；2650Please respect copyright.ＰＥＮＡＮＡIS34UIWKND
2650Please respect copyright.ＰＥＮＡＮＡd7Z9MgkoQl
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。2650Please respect copyright.ＰＥＮＡＮＡZ7cyb1xgyW
2650Please respect copyright.ＰＥＮＡＮＡ94kU2Wq4Sv
而臭狐是否由這細菌引起或有份參與，文中並沒有提及。2650Please respect copyright.ＰＥＮＡＮＡHHbIwuhsTj
