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。1970Please respect copyright.ＰＥＮＡＮＡjX7EU2zneI

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。1970Please respect copyright.ＰＥＮＡＮＡwHdwCH6ltP

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。1970Please respect copyright.ＰＥＮＡＮＡNe6QpVNhXo

（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1970Please respect copyright.ＰＥＮＡＮＡ1GCRbrBkuH

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。1970Please respect copyright.ＰＥＮＡＮＡEHT54tllia
1970Please respect copyright.ＰＥＮＡＮＡtrV9jOagxY
外分泌汗腺的主要功能就是散發汗水幫助散熱，調節體溫。1970Please respect copyright.ＰＥＮＡＮＡU5INTmmmsZ
1970Please respect copyright.ＰＥＮＡＮＡRTnzzlI3mR
而大汗腺的主要功能，到目前為止仍未能搞得清楚。1970Please respect copyright.ＰＥＮＡＮＡZoPvOR6N1f

（圖2）下列三點為文中所找出的異味散發機制。1970Please respect copyright.ＰＥＮＡＮＡ8cbffZh2OI
1970Please respect copyright.ＰＥＮＡＮＡHPWqJuNRbh
1.大汗腺釋出無味物質Cys-Gly-3M3SH。1970Please respect copyright.ＰＥＮＡＮＡGKkYTtt087
1970Please respect copyright.ＰＥＮＡＮＡC3pLfSFubV
2.腋下某品種的葡萄球菌消化Cys-Gly-3M3SH。1970Please respect copyright.ＰＥＮＡＮＡk115FE2dGT
1970Please respect copyright.ＰＥＮＡＮＡ5OLHkPCzjD
3. 葡萄球菌消化過後，吐出帶有異味的3M3SH。1970Please respect copyright.ＰＥＮＡＮＡvr73T2Z2jm
1970Please respect copyright.ＰＥＮＡＮＡP8P2apVDRZ
換句話說，腋下的異味就是由這些細菌引致而成的。1970Please respect copyright.ＰＥＮＡＮＡY1UrqCWu5A

（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。1970Please respect copyright.ＰＥＮＡＮＡnBzNehGwg9
1970Please respect copyright.ＰＥＮＡＮＡLKE2uks9qq
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。1970Please respect copyright.ＰＥＮＡＮＡGl51MHKkYa
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。1970Please respect copyright.ＰＥＮＡＮＡ3NXI0A7eeY
1970Please respect copyright.ＰＥＮＡＮＡNUP4NHp2wy
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；1970Please respect copyright.ＰＥＮＡＮＡzINlrGxD09
1970Please respect copyright.ＰＥＮＡＮＡLN3mrYsAlP
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。1970Please respect copyright.ＰＥＮＡＮＡMCb6OYdgQm
1970Please respect copyright.ＰＥＮＡＮＡd59apmVxzL
而臭狐是否由這細菌引起或有份參與，文中並沒有提及。1970Please respect copyright.ＰＥＮＡＮＡyajSt16is6
