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。2148Please respect copyright.ＰＥＮＡＮＡLKNyC9cVRU
2148Please respect copyright.ＰＥＮＡＮＡuT0Eih9aGW
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。2148Please respect copyright.ＰＥＮＡＮＡmm1CZuE0oJ
2148Please respect copyright.ＰＥＮＡＮＡKFBIH7muzX
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。2148Please respect copyright.ＰＥＮＡＮＡvSz9ZkeNUq

（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2148Please respect copyright.ＰＥＮＡＮＡ7nR5VlE8QY
(Apocrine Sweat Glands)2148Please respect copyright.ＰＥＮＡＮＡotkbNGkOeN

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。2148Please respect copyright.ＰＥＮＡＮＡykxr2PICjx
2148Please respect copyright.ＰＥＮＡＮＡqXlXCSxhL0
外分泌汗腺的主要功能就是散發汗水幫助散熱，調節體溫。2148Please respect copyright.ＰＥＮＡＮＡgj3NrgLX65
2148Please respect copyright.ＰＥＮＡＮＡwngWzNuiwA
而大汗腺的主要功能，到目前為止仍未能搞得清楚。2148Please respect copyright.ＰＥＮＡＮＡZwPIGEyBUM

（圖2）下列三點為文中所找出的異味散發機制。2148Please respect copyright.ＰＥＮＡＮＡwrjNEAu8EQ
2148Please respect copyright.ＰＥＮＡＮＡ9lXdSnEzp2
1.大汗腺釋出無味物質Cys-Gly-3M3SH。2148Please respect copyright.ＰＥＮＡＮＡmD5crhWZv1
2148Please respect copyright.ＰＥＮＡＮＡIClIAurSyJ
2.腋下某品種的葡萄球菌消化Cys-Gly-3M3SH。2148Please respect copyright.ＰＥＮＡＮＡJcrI8q9eJW
2148Please respect copyright.ＰＥＮＡＮＡFInooTOJ5K
3. 葡萄球菌消化過後，吐出帶有異味的3M3SH。2148Please respect copyright.ＰＥＮＡＮＡ8PKZ0TQrjl
2148Please respect copyright.ＰＥＮＡＮＡTL8OMHDGcn
換句話說，腋下的異味就是由這些細菌引致而成的。2148Please respect copyright.ＰＥＮＡＮＡ5aH2snI2jg

2148Please respect copyright.ＰＥＮＡＮＡgZxXxUK38W

（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。2148Please respect copyright.ＰＥＮＡＮＡNmn6JHCcS3
2148Please respect copyright.ＰＥＮＡＮＡDxO8DuS0SA
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。2148Please respect copyright.ＰＥＮＡＮＡgRR5n12HFS
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。2148Please respect copyright.ＰＥＮＡＮＡrxo2Ux7gOJ
2148Please respect copyright.ＰＥＮＡＮＡ68TEbrF2Ml
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；2148Please respect copyright.ＰＥＮＡＮＡgJprOHpvyZ
2148Please respect copyright.ＰＥＮＡＮＡS1UvxLMuGo
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。2148Please respect copyright.ＰＥＮＡＮＡcxrjZS9gQX
2148Please respect copyright.ＰＥＮＡＮＡNsLUJflo3r
而臭狐是否由這細菌引起或有份參與，文中並沒有提及。2148Please respect copyright.ＰＥＮＡＮＡGwmI1Djoxj
