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。1937Please respect copyright.ＰＥＮＡＮＡ661JITgn5e

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。1937Please respect copyright.ＰＥＮＡＮＡpXNpqU8JCF

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。1937Please respect copyright.ＰＥＮＡＮＡ6J3X7SypdY

（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1937Please respect copyright.ＰＥＮＡＮＡlYKB5RFLEe
(Apocrine Sweat Glands)1937Please respect copyright.ＰＥＮＡＮＡd2zIhZz7Xi

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。1937Please respect copyright.ＰＥＮＡＮＡXhCG8xJfjD
1937Please respect copyright.ＰＥＮＡＮＡNtI3x3zgzC
外分泌汗腺的主要功能就是散發汗水幫助散熱，調節體溫。1937Please respect copyright.ＰＥＮＡＮＡK3mVo8osUj
1937Please respect copyright.ＰＥＮＡＮＡCF3TrePI4h
而大汗腺的主要功能，到目前為止仍未能搞得清楚。1937Please respect copyright.ＰＥＮＡＮＡUpSXAZbGML

（圖2）下列三點為文中所找出的異味散發機制。1937Please respect copyright.ＰＥＮＡＮＡfbzVXxWPRI
1937Please respect copyright.ＰＥＮＡＮＡfIXZqbkSoU
1.大汗腺釋出無味物質Cys-Gly-3M3SH。1937Please respect copyright.ＰＥＮＡＮＡ3XovhzdkBl
1937Please respect copyright.ＰＥＮＡＮＡPRm7ScnqYj
2.腋下某品種的葡萄球菌消化Cys-Gly-3M3SH。1937Please respect copyright.ＰＥＮＡＮＡhtCNz1zPMJ
1937Please respect copyright.ＰＥＮＡＮＡ2BfVXwyScX
3. 葡萄球菌消化過後，吐出帶有異味的3M3SH。1937Please respect copyright.ＰＥＮＡＮＡxoZqJstgQC
1937Please respect copyright.ＰＥＮＡＮＡ1LHl0uF0LH
換句話說，腋下的異味就是由這些細菌引致而成的。1937Please respect copyright.ＰＥＮＡＮＡw8FNEyJRox

（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。1937Please respect copyright.ＰＥＮＡＮＡ2viFH8nCeV
1937Please respect copyright.ＰＥＮＡＮＡpH7E0YYokb
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。1937Please respect copyright.ＰＥＮＡＮＡB3KM8Wts0c
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。1937Please respect copyright.ＰＥＮＡＮＡDt8pbWsmSM
1937Please respect copyright.ＰＥＮＡＮＡy0qaM0u7xH
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；1937Please respect copyright.ＰＥＮＡＮＡcGW8ITjjLd
1937Please respect copyright.ＰＥＮＡＮＡ8939706CRY
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。1937Please respect copyright.ＰＥＮＡＮＡTPPaWZPUNi
1937Please respect copyright.ＰＥＮＡＮＡ9jbZD6FDFi
而臭狐是否由這細菌引起或有份參與，文中並沒有提及。1937Please respect copyright.ＰＥＮＡＮＡBt3501R5z9
