雙語：科學(xué)家發(fā)現(xiàn)母乳可治療癌癥

　　瑞典科學(xué)家意外發(fā)現(xiàn)母乳中含有一種物質(zhì)可以有效殺死癌細胞，這是否意味著人類終結(jié)癌癥歷史的日子即將到來,？

　　Breast milk is being used to fight cancer after scientists accidentally discovered it contains a substance that kills tumour cells.

　　在科學(xué)家意外發(fā)現(xiàn)母乳含有可以殺死腫瘤細胞的物質(zhì)之后，人們正在用母乳來治療癌癥,。

　　Trials in patients with bladder cancer have already yielded promising results and researchers believe the compound breast milk contains – nicknamed Hamlet – will also help tackle bowel cancer and cervical cancer.

　　在膀胱癌患者身上的實驗已經(jīng)取得了可喜的成果,，而研究人員們認為含有“哈姆雷特”物質(zhì)的復(fù)方母乳對腸癌和宮頸癌也有療效。

　　They also say it homes in on cancer cells while leaving healthy cells unharmed – so it has none of the debilitating side effects of chemotherapy.

　　研究人員還表示稱,，這種物質(zhì)會在癌細胞上生長卻又不會損傷健康的細胞,，因此不會有像化療那樣帶來的虛弱副作用。

　　Professor Catharina Svanborg, who made the initial discovery, said last night: ‘There’s something magical about Hamlet’s ability to target tumour cells and kill them.’

　　最先發(fā)現(xiàn)該現(xiàn)象的凱瑟琳娜教授表示稱：“‘哈姆雷特’能夠很神奇地以腫瘤細胞為目標(biāo)并殺死它們,�,！�

　　She said human breast milk contained a protein called alpha-lactalbumin, which is transformed into a cancer-fighting agent when in the gut.

　　她表示母乳含有一種被稱之為α-乳白蛋白的蛋白質(zhì)，可以在腸道里轉(zhuǎn)化為一種抗癌劑,。

　　Prof Svanborg, an immunologist at Lund University in Sweden, made the chance discovery that the substance kills tumour cells when working on antibiotics.

　　凱瑟琳娜教授是瑞典隆德大學(xué)的免疫學(xué)家,，她在對抗生素進行研究時偶然發(fā)現(xiàn)這種物質(zhì)可以殺死腫瘤細胞。

　　She said: ‘We were looking for novel antimicrobial agents, and new breast milk is a very good source of these. During one experiment we needed human cells and bacteria to be present, and we chose human tumour cells for practical reasons.

　　她表示：“我們當(dāng)時正在尋找新的抗菌藥物,，而母乳是這些藥物的很好來源,。在一次試驗中我們需要人類細胞和細菌，而出于實際的原因我們選擇了腫瘤細胞,�,！�

　　‘To our amazement, when we added this compound of milk, the tumour cells died. It was a totally serendipitous discovery.’

　　“令我們驚訝的是，當(dāng)我們添加這種復(fù)方母乳的時候,，腫瘤細胞被殺死了,。這完全是一個偶然的發(fā)現(xiàn)。”

　　The substance attacks cancer cells in numerous ways – first evading the cell’s outer defences, then targeting the ‘power station’ mitochondria and the ‘instruction manual’ nucleus. These actions cut off the cell’s energy source and ‘programme’ it to commit suicide, in a process called apoptosis.

　　這種物質(zhì)會以多種方式對癌細胞進行攻擊——首先回避癌細胞的外部防御,，然后瞄準(zhǔn)“能量中心”線粒體和“指揮部”細胞核,。這些行為切斷了癌細胞的能量來源、并使之“自殺”——這個過程被稱之為細胞凋亡,。

　　Early trials in patients with bladder cancer show those injected with Hamlet start shedding dead tumour cells in their urine within days.

　　在對膀胱癌患者的早期試驗中,，人們發(fā)現(xiàn)注射“哈姆雷特”之后幾天內(nèi)患者的小便中就發(fā)現(xiàn)了脫落的死亡腫瘤細胞。

　　A full-scale trial pitting Hamlet against a placebo ‘dummy drug’ is now planned.

　　目前科學(xué)家們正在計劃進行“哈姆雷特”和安慰劑“假藥物”之間的全面對比試驗,。(愛語吧)
