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。2039Please respect copyright.ＰＥＮＡＮＡiRMqVpltvu
2039Please respect copyright.ＰＥＮＡＮＡmqke2e29Ut
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。2039Please respect copyright.ＰＥＮＡＮＡH6Diaa8IZY
2039Please respect copyright.ＰＥＮＡＮＡ3RT4WMEp0I
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。2039Please respect copyright.ＰＥＮＡＮＡ4FXINPoWCA

（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2039Please respect copyright.ＰＥＮＡＮＡEFkezejb1B
(Apocrine Sweat Glands)2039Please respect copyright.ＰＥＮＡＮＡs9z2GP09s5

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。2039Please respect copyright.ＰＥＮＡＮＡiPmiZb0ypf
2039Please respect copyright.ＰＥＮＡＮＡHX6U2SidaC
外分泌汗腺的主要功能就是散發汗水幫助散熱，調節體溫。2039Please respect copyright.ＰＥＮＡＮＡQ8QxX6B5dk
2039Please respect copyright.ＰＥＮＡＮＡmdEC2V2G7V
而大汗腺的主要功能，到目前為止仍未能搞得清楚。2039Please respect copyright.ＰＥＮＡＮＡ7eMmil6t1P

（圖2）下列三點為文中所找出的異味散發機制。2039Please respect copyright.ＰＥＮＡＮＡiyo2vJ9BnT
2039Please respect copyright.ＰＥＮＡＮＡ3HLrY5GjcM
1.大汗腺釋出無味物質Cys-Gly-3M3SH。2039Please respect copyright.ＰＥＮＡＮＡaOJ6DKxLQ0
2039Please respect copyright.ＰＥＮＡＮＡMeNiO8XpvU
2.腋下某品種的葡萄球菌消化Cys-Gly-3M3SH。2039Please respect copyright.ＰＥＮＡＮＡx5kEfcofhK
2039Please respect copyright.ＰＥＮＡＮＡkAhRkgypnQ
3. 葡萄球菌消化過後，吐出帶有異味的3M3SH。2039Please respect copyright.ＰＥＮＡＮＡWUPVImg74b
2039Please respect copyright.ＰＥＮＡＮＡ6uoFnfz1Um
換句話說，腋下的異味就是由這些細菌引致而成的。2039Please respect copyright.ＰＥＮＡＮＡb7uPFMR87j

（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。2039Please respect copyright.ＰＥＮＡＮＡI7HWbfDYFz
2039Please respect copyright.ＰＥＮＡＮＡz1mBrOc46v
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。2039Please respect copyright.ＰＥＮＡＮＡnLkVHJOkxS
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。2039Please respect copyright.ＰＥＮＡＮＡRZCjnlKHsy
2039Please respect copyright.ＰＥＮＡＮＡfgcfoGnDjb
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；2039Please respect copyright.ＰＥＮＡＮＡInd35iBRtL
2039Please respect copyright.ＰＥＮＡＮＡnZSzlxa3vW
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。2039Please respect copyright.ＰＥＮＡＮＡHi9BfYzfSL
2039Please respect copyright.ＰＥＮＡＮＡ6ckFxaO2ON
而臭狐是否由這細菌引起或有份參與，文中並沒有提及。2039Please respect copyright.ＰＥＮＡＮＡNNNTF8D9HN
