因人而異，膀胱/尿袋 (Urinary Bladder)一般來說可以儲存300-500ml尿液。1090Please respect copyright.ＰＥＮＡＮＡmZSp9Nevwb

尿液的其中一個功能，就是將體內的毒素或細菌排出，而膀胱經常有大量尿液儲存，為罪惡的蘊藏之所，體內的警署。1090Please respect copyright.ＰＥＮＡＮＡjlCZ9XHB3H

想深一層，身體的細菌經由尿液聚首一堂，膀胱豈不是非常容易令受到感染?1090Please respect copyright.ＰＥＮＡＮＡUWwEJKmTNg

（致病的細菌及毒素亦可從糞便排出）1090Please respect copyright.ＰＥＮＡＮＡRaq4EmdQP1

（圖2）尿調理素(Uromodulin/Tamm–Horsfall Protein)是尿液其中一種常見的主要蛋白，主要在腎臟管道生產。1090Please respect copyright.ＰＥＮＡＮＡkeuTtE6Yqu

它被認定為有抵禦細菌感染的作用，但一直以來也沒有充分的證據得以證明。1090Please respect copyright.ＰＥＮＡＮＡBV0W5Pwf98
1090Please respect copyright.ＰＥＮＡＮＡRiY0P7D5bj
近日，有科學家利用最新的電子顯微鏡技術及各種實驗輔證（Ref1)，終於確立得到尿調理素抵禦細菌感染的功能。1090Please respect copyright.ＰＥＮＡＮＡ6aQE4VGji2

（圖3）先簡單重溫一下細菌的外部結構，今次我們會特別著重提及Pili，它賦予細菌與外部接觸的能力。1090Please respect copyright.ＰＥＮＡＮＡMr22MIoawE

（圖4）左邊是文中的圖片，黃色箭嘴頭所指示的就是細菌的pili，它能夠與uromodulin建立非常穩定的連結；1090Please respect copyright.ＰＥＮＡＮＡM3F67TsEzF
箇中的連結需要糖份組織的幫助。1090Please respect copyright.ＰＥＮＡＮＡm8DGGnrclg

（圖5）Uromodulin在尿液的大量存在，將會強迫致病的大腸桿菌聚在一起，以免大腸桿菌能夠與膀胱內壁接觸及進行感染。1090Please respect copyright.ＰＥＮＡＮＡRilwyXTD2b
1090Please respect copyright.ＰＥＮＡＮＡgtb7pVhQ9L
1090Please respect copyright.ＰＥＮＡＮＡShPqOW5kBD
以壓倒性的數量，簡單將致病的大腸桿菌聚集及封鎖在一起，這種防禦機制相對地直接簡單。1090Please respect copyright.ＰＥＮＡＮＡIjoaTSlFcL
至於Uromodulin能否與所有已知的致命細菌結合、會否有著其他的機制及功能，還需要進一步的調查。1090Please respect copyright.ＰＥＮＡＮＡFwHsTZJbOx
