痰呈綠色,是否一定等於有細菌感染呢?408Please respect copyright.PENANA3lEiAXkrew

(圖2)我們身體其中一種免疫細胞含有一種酶素名為Myeloperoxidase,它在結晶狀態下會呈綠色。408Please respect copyright.PENANABd15tDTmIN

因此,痰呈綠色的其中一道原因就是免疫細胞在大開殺戒中,其綠色的酶素不經意間殘留在痰液裡頭。408Please respect copyright.PENANAnOcdyz5SWy

而另一個痰呈綠色的可能性,就是病人不幸受到綠膿桿菌感染。408Please respect copyright.PENANAF8QjBfbMXR

綠膿桿菌內含藍綠色的綠膿素(pyocyanin),綠膿素能侵害宿主的抗氧化功能,甚至能影響細胞製造能源的機制,非常惡毒。408Please respect copyright.PENANAtIl32Y5h3R

而這病菌則較常在慢性肺炎患者的痰液中找得到。408Please respect copyright.PENANAyv01YEiwbo

(圖3)但是,就算痰呈黃色或綠色,亦不等於病人一定是受到細菌感染。408Please respect copyright.PENANA2Kncb6KdMS

有研究找來相似年齡、性別、職業甚至是吸煙習慣的組別作對照,發現出現黃綠痰徵狀者無論給予抗生素與否,他們的康復速度及情況均無顯著分別。408Please respect copyright.PENANAmggphIIoQP

因此,單純依憑痰的顏色是並不能夠作出正確的治療判斷。408Please respect copyright.PENANAaClaMjiG9B
