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。1999Please respect copyright.ＰＥＮＡＮＡM4fCZSHRdw

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。1999Please respect copyright.ＰＥＮＡＮＡT2JRD7Bvur

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。1999Please respect copyright.ＰＥＮＡＮＡHXpwIYQJyB

（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1999Please respect copyright.ＰＥＮＡＮＡesz3fhiKlV

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。1999Please respect copyright.ＰＥＮＡＮＡoAeXQrypzK

外分泌汗腺的主要功能就是散發汗水幫助散熱，調節體溫。1999Please respect copyright.ＰＥＮＡＮＡsa86CpE8uX
1999Please respect copyright.ＰＥＮＡＮＡ7FCLUPyvOi
而大汗腺的主要功能，到目前為止仍未能搞得清楚。1999Please respect copyright.ＰＥＮＡＮＡHkLuy58uEW

（圖2）下列三點為文中所找出的異味散發機制。1999Please respect copyright.ＰＥＮＡＮＡjKsPkv624C
1999Please respect copyright.ＰＥＮＡＮＡ11qksHp9pD
1.大汗腺釋出無味物質Cys-Gly-3M3SH。1999Please respect copyright.ＰＥＮＡＮＡacvkoD55yJ
1999Please respect copyright.ＰＥＮＡＮＡDo4q1B1aek
2.腋下某品種的葡萄球菌消化Cys-Gly-3M3SH。1999Please respect copyright.ＰＥＮＡＮＡlJL8NPNAG9
1999Please respect copyright.ＰＥＮＡＮＡDqhX2gpxbB
3. 葡萄球菌消化過後，吐出帶有異味的3M3SH。1999Please respect copyright.ＰＥＮＡＮＡeW8ScWSWO4
1999Please respect copyright.ＰＥＮＡＮＡzVOnlrjV4S
換句話說，腋下的異味就是由這些細菌引致而成的。1999Please respect copyright.ＰＥＮＡＮＡkNNgGh4vlR

（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。1999Please respect copyright.ＰＥＮＡＮＡmP5BOGN64d
1999Please respect copyright.ＰＥＮＡＮＡm00omQjq24
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。1999Please respect copyright.ＰＥＮＡＮＡ8dh1IG7GcD
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。1999Please respect copyright.ＰＥＮＡＮＡddakTQpEMY
1999Please respect copyright.ＰＥＮＡＮＡOuiC4bxGja
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；1999Please respect copyright.ＰＥＮＡＮＡvcXXz5LZWg
1999Please respect copyright.ＰＥＮＡＮＡCY3gldtjSU
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。1999Please respect copyright.ＰＥＮＡＮＡibSibm36p1
1999Please respect copyright.ＰＥＮＡＮＡGeqTDTHAph
而臭狐是否由這細菌引起或有份參與，文中並沒有提及。1999Please respect copyright.ＰＥＮＡＮＡ8PswcBZ2a8
