常喝绿茶能预防艾滋病毒感染

一项美国和英国的联合研究认为，喝绿茶有助于防止艾滋病病毒感染。绿茶并非艾滋病的解药，也不是避免感染艾滋病的安全办法。这项研究仅仅是认为表没食子儿茶素没食子酸酯(EGCG)具有用于艾滋病病毒感染辅助治疗的潜力。
这项初步研究发表在《变态反应与临床免疫学杂志》上，它是英国谢菲尔德大学和美国德克萨斯州Baylor医学院之间的一个联合研究项目。该研究小组对绿茶中一种叫表没食子儿茶素没食子酸酯(EGCG)的黄酮类化合物进行了试管试验，结果表明这种物质能与CD4免疫系统T-淋巴细胞受体结合，并使艾滋病病毒停止与该受体结合。
研究人员之一，谢菲尔德大学分子生物学及生物技术系的Williamson教授说，“我们的研究表明，喝绿茶能降低受艾滋病病毒感染的风险，而且还能减慢艾滋病病毒的扩散速度。但要想凭此就认为这项研究表明绿茶能杜绝艾滋病病毒在免疫系统中获得落脚点，尚为时过早。评论家们对此仍保持谨慎。因为某些化合物在试管试验时，会在“微观”的细胞级别上显示有良好的效果，但在“宏观”的生命组织免疫系统级别上，并不一定会具有相同的效果。
Williamson教授敏锐地指出，绿茶并非艾滋病的解药，也不是避免感染艾滋病的安全办法。这项研究仅仅是认为表没食子儿茶素没食子酸酯(EGCG)具有用于艾滋病病毒感染辅助治疗的潜力。Williamson教授换了种表达方式，“绿茶应该与传统的药物合用，用来改善那些已经感染艾滋病的人的生活质量。”他还提到，进一步的研究正在进行当中，以发现不同数量的绿茶的效果会是怎样。
这项研究由美国国家卫生研究所和一些研究、教育及其它资金资助。去年九月，一项发表在《美国医学会学报》上的日本研究指出，大量饮用绿茶与死于各种原因及心血管疾病的风险下降两者之间存在关联。其它研究还发现了饮用绿茶与癌症之间的有益联系。

A joint American and British studies suggest that drinking green tea helps prevent HIV infection. Green tea is not the antidote AIDS or HIV infection is to avoid the security approach. The study is just that epigallocatechin gallate (EGCG) has for the adjuvant treatment of HIV infection potential.
The preliminary study published in the "allergy and clinical immunology journal," It is the University of Sheffield, Britain and the United States, Texas, between Baylor College of Medicine, a joint research projects. The team of green tea called epigallocatechin gallate (EGCG) of flavonoids had a test-tube experiments, the results show that the material with CD4 immune system T-cell receptor-binding and AIDS To stop the virus and the receptor-binding.
One of the researchers, University of Sheffield in molecular biology and biotechnology department, Professor Williamson said, "Our research shows that drinking green tea can reduce HIV infection risks, but also slow down the speed of the spread of the AIDS virus. But Would like to think that by virtue of the study showed that green tea can eliminate the AIDS virus in the immune system in the end-result was still too early. Critics are still cautious. Because some compounds in the test tube, in the "micro - "The cell level to show good results, but in the" macro "level the lives of the Organization of the immune system, does not necessarily have the same effect.
Williamson, a professor keen to point out that green tea is not the antidote AIDS or HIV infection is to avoid the security approach. The study is just that epigallocatechin gallate (EGCG) has for the adjuvant treatment of HIV infection potential. Williamson, a professor for the kind of expression, "green tea should be combined with traditional medicine to improve those already infected with the AIDS quality of life." He also mentioned that further studies were under way to find a different number of green tea The effect is going to be.
The study was conducted by the National Institutes of Health and a number of research, education and other funds. Last September, one published in the "Journal of the American Medical Association," Japan's research indicates that drinking green tea and a large number died in Cardiovascular Disease and a variety of reasons for the decline in risk between the two linked. Other research has also found that drinking green tea with a useful link between the cancer.
