Duct Tape and Warts
管狀膠帶和疣
Have you ever used duct tape to tape a duct? Do you even know what a duct is? Maybe not. But you definitely know what duct tape is, and you’ve probably used it to fix everything from glasses to flashlights. Now, thanks to one study, we can officially add to the already long list of things to do with duct tape: curing warts. That’s right, duct tape might be used to cure warts.
The study tested duct tape against cryotherapy, which uses liquid nitrogen to freeze warts. Of a test group of fifty-one wart patients, roughly half received cryotherapy, the other half duct tape. The duct tape patients wore pieces of tape over their warts for six days and then removed it for twelve hours.
After soaking the wart in water and gently scrubbing it with pumice stone, the procedure was repeated for up to two months, or until the wart disappeared. The cryotherapy patients received a maximum of six treatments over the same time period. By the end, 85% of duct tape patients saw their warts vanish completely, while only 65% of cryotherapy recipients had similar results.
As for precisely what makes duct tape so effective, researchers are still uncertain. Scientists speculate that by mildly irritating the wart, the tape activates the immune system which suppresses the viral microbes that cause warts. Robbed of its microbes, the wart gradually vanishes.
Although duct tape has gotten all the publicity, it may be the case that other kinds of tape would do just as well. In any case, the next time you get a wart, talk to your medical professional about duct tape.
你曾經(jīng)用管狀膠帶粘過管道嗎?你知道管道是什么嗎?也許你不知道。但你一定知道膠帶，并且你可能用它來固定任何東西，比如眼鏡或手電筒?，F(xiàn)在，多虧了一項研究，我們可以正式在膠帶能做的事情單上增加一件事：治療疣。是的，膠帶可用于治療疣。
該項研究對膠帶治療疣和通過液態(tài)氮冷凍治療疣進(jìn)行了對照測試。測試組有五十一名病人，大約一半的病人接受了冷凍療法，另一半病人接受管狀膠帶治療。管狀膠帶療法病人在長疣的地方貼上膠帶，貼6天后再取下。
在水中浸泡疣后，用浮石輕輕擦拭其表面，這樣堅持2個月，或直到疣消失。冷凍療法的病人在同樣時間內(nèi)接受了6次療法。在治療結(jié)束時，管狀膠帶治療組中占85%的病人尋常疣完全消退;而冷凍療法治療組中只有65%的病人尋常疣完全消退。
到底是什么使得管狀膠帶如此有效，研究人員目前還不能確定。科學(xué)家們推測也許是由于輕度地刺激疣，膠帶激活了免疫系統(tǒng)，抑制了產(chǎn)生疣的病毒微生物的產(chǎn)生。微生沒有了，疣就漸漸消失了。
盡管管狀膠帶已經(jīng)被廣泛宣傳，但可能另外一種膠帶也同樣有效。不管怎樣，以后如果長了疣，與你的專業(yè)醫(yī)師談?wù)劰軤钅z帶吧。
注釋：
疣是人類乳頭瘤病毒(HPV)所引起，以往認(rèn)為這些疾病是慢性良性疾病，但發(fā)現(xiàn)HPV感染后有一部分會導(dǎo)致惡性腫瘤，如皮膚癌、舌癌和宮頸癌等，因而引起人們的重視。疣是病毒引起的以細(xì)胞增生反應(yīng)為主的一類皮膚淺表性良性贅生物。受到感染后，約潛伏四個月左右發(fā)病。多見于青少年。
