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。1941Please respect copyright.ＰＥＮＡＮＡ0PE4Ut9TJ5
1941Please respect copyright.ＰＥＮＡＮＡXMH8C1IuK3
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。1941Please respect copyright.ＰＥＮＡＮＡb20EL5i9k6

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。1941Please respect copyright.ＰＥＮＡＮＡLUVlhtF5an

（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1941Please respect copyright.ＰＥＮＡＮＡMmgT04COku
(Apocrine Sweat Glands)1941Please respect copyright.ＰＥＮＡＮＡfhOnhpZyFV

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。1941Please respect copyright.ＰＥＮＡＮＡ2Rr8fd8H8G
1941Please respect copyright.ＰＥＮＡＮＡLoTQSAF7XW
外分泌汗腺的主要功能就是散發汗水幫助散熱，調節體溫。1941Please respect copyright.ＰＥＮＡＮＡYARzuJFhTW
1941Please respect copyright.ＰＥＮＡＮＡG4t7Qu3aE9
而大汗腺的主要功能，到目前為止仍未能搞得清楚。1941Please respect copyright.ＰＥＮＡＮＡm4Fskdbstz

（圖2）下列三點為文中所找出的異味散發機制。1941Please respect copyright.ＰＥＮＡＮＡ9rAMcMIzkm
1941Please respect copyright.ＰＥＮＡＮＡtsAZxwjnHn
1.大汗腺釋出無味物質Cys-Gly-3M3SH。1941Please respect copyright.ＰＥＮＡＮＡXecmzQGWGe
1941Please respect copyright.ＰＥＮＡＮＡw1hyQLJ6AO
2.腋下某品種的葡萄球菌消化Cys-Gly-3M3SH。1941Please respect copyright.ＰＥＮＡＮＡklAnoonFoV
1941Please respect copyright.ＰＥＮＡＮＡT6vOJ2AoWt
3. 葡萄球菌消化過後，吐出帶有異味的3M3SH。1941Please respect copyright.ＰＥＮＡＮＡocDQ7hzpYj
1941Please respect copyright.ＰＥＮＡＮＡrae7XY0yu2
換句話說，腋下的異味就是由這些細菌引致而成的。1941Please respect copyright.ＰＥＮＡＮＡ8JwEwTOM9J

（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。1941Please respect copyright.ＰＥＮＡＮＡQ4NA0C62CT
1941Please respect copyright.ＰＥＮＡＮＡNcnrD59iQJ
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。1941Please respect copyright.ＰＥＮＡＮＡigVRptRq2I
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。1941Please respect copyright.ＰＥＮＡＮＡAowiPrlgRX
1941Please respect copyright.ＰＥＮＡＮＡ6JOUrhjSgs
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；1941Please respect copyright.ＰＥＮＡＮＡ6s4d181H4h
1941Please respect copyright.ＰＥＮＡＮＡHSXtTeTSUh
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。1941Please respect copyright.ＰＥＮＡＮＡeBYrkQqFQe
1941Please respect copyright.ＰＥＮＡＮＡ7xRt5YzWT5
而臭狐是否由這細菌引起或有份參與，文中並沒有提及。1941Please respect copyright.ＰＥＮＡＮＡCru4DCdy2C
