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。2665Please respect copyright.ＰＥＮＡＮＡOQhpqehLoN
2665Please respect copyright.ＰＥＮＡＮＡNrRdPpe90i
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。2665Please respect copyright.ＰＥＮＡＮＡyEL3y8mYgw

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。2665Please respect copyright.ＰＥＮＡＮＡXelPDXmG9O

（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2665Please respect copyright.ＰＥＮＡＮＡUAG3EOzxUa
(Apocrine Sweat Glands)2665Please respect copyright.ＰＥＮＡＮＡ7oMQh2KlTv

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。2665Please respect copyright.ＰＥＮＡＮＡO1dLRE0XRE
2665Please respect copyright.ＰＥＮＡＮＡwgnf5yHtAD
外分泌汗腺的主要功能就是散發汗水幫助散熱，調節體溫。2665Please respect copyright.ＰＥＮＡＮＡbSnBaUWnpJ
2665Please respect copyright.ＰＥＮＡＮＡCjSVQJ6LXv
而大汗腺的主要功能，到目前為止仍未能搞得清楚。2665Please respect copyright.ＰＥＮＡＮＡ4JSMiDkJNl

（圖2）下列三點為文中所找出的異味散發機制。2665Please respect copyright.ＰＥＮＡＮＡnSXANmY9P8
2665Please respect copyright.ＰＥＮＡＮＡLBS0xMryQ3
1.大汗腺釋出無味物質Cys-Gly-3M3SH。2665Please respect copyright.ＰＥＮＡＮＡtfch1JzrhB
2665Please respect copyright.ＰＥＮＡＮＡryjZbZwMJV
2.腋下某品種的葡萄球菌消化Cys-Gly-3M3SH。2665Please respect copyright.ＰＥＮＡＮＡxBylQ34qup
2665Please respect copyright.ＰＥＮＡＮＡ5zyVXIyNRf
3. 葡萄球菌消化過後，吐出帶有異味的3M3SH。2665Please respect copyright.ＰＥＮＡＮＡK2liFpq6x6
2665Please respect copyright.ＰＥＮＡＮＡTtHOejiGu5
換句話說，腋下的異味就是由這些細菌引致而成的。2665Please respect copyright.ＰＥＮＡＮＡCbUtx6DJ8b

（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。2665Please respect copyright.ＰＥＮＡＮＡIQ8QNHmJhk
2665Please respect copyright.ＰＥＮＡＮＡQgwIlzf3f5
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。2665Please respect copyright.ＰＥＮＡＮＡJcQ1jGZrPa
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。2665Please respect copyright.ＰＥＮＡＮＡQnhOpDhcuR
2665Please respect copyright.ＰＥＮＡＮＡSzq4ULA6Uj
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；2665Please respect copyright.ＰＥＮＡＮＡ7tsX9PCbRO
2665Please respect copyright.ＰＥＮＡＮＡNmXKuLlGOf
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。2665Please respect copyright.ＰＥＮＡＮＡeoX8YB4Bol
2665Please respect copyright.ＰＥＮＡＮＡ6d5jT2achV
而臭狐是否由這細菌引起或有份參與，文中並沒有提及。2665Please respect copyright.ＰＥＮＡＮＡ6eQ0QqiSPw
