水果蔬菜中含能杀癌细胞成分
新华社洛杉矶5月8日电美国科学家日前公布的一项研究报告显示，水果、蔬菜及红酒中含有的一种抗氧化剂成分能杀死白血病患者体内的血癌细胞，同时不伤及健康细胞。
美国宾夕法尼亚州匹兹堡大学医学院的专家在美国《生物化学杂志》上报告说，不少水果、蔬菜和红酒中有一种名叫花青素的抗氧化剂。研究人员从黑树莓中提取花青素，并分析其中花青素-3-芸香糖甙(C-3-R)的搭配机制，研究其对血癌细胞的作用。研究发现，低剂量的C-3-R能在18小时内把某实验样本中的一半血癌细胞杀死。如果使用高剂量的C-3-R，可在18小时内把该样本中的所有血癌细胞杀死。
研究人员说，实验证明C-3-R可使细胞产生一种过氧化物，导致血癌细胞死亡，但这种过氧化物对正常细胞没有毒性。
The Xinhua news agency Los Angeles gives or get an electric shock a research paper that the American scientist announced recently to show on May 8, have in fruit, vegetable and red wine of a kind of anti- oxidizing agent composition can kill the leukemia cell of the leukemia sufferer's in vivo, don't harm in the meantime and healthy cell.
The expert of American Pennsylvania, Pittsburgh university medical college is in the United States 《biochemistery magazine 》report to tell to say, there is a specific name in not a few fruits, vegetable and red wine calling anti- oxidizing agent of spend the green vegetable.Researcher the retrieval spends a green vegetable from the black tree Mei, and analyze to spend a green vegetable among them-3-match of the Yun fragrant sugar Mao(C-3-R) mechanism, study an its action for leukemia cell.The research discover that the C-3-R of low doses can within 18 hours the half in the some experiment sample the leukemia cell kill.If use the C-3-R of high dosage, can kill that all leukemia cells in the sample within 18 hours.
Researcher says that testing the certificate C-3-R can make the cell produce 1 kind to lead oxide, cause the leukemia cell die, but this kind of lead oxide to normal the cell have no toxicity.
