美国Alabama大学Butterworth医师对140例宫颈细胞有癌前变化的年轻妇女进行了一次随机双盲临床试验。这些妇女分为每日服用10mg叶酸组及安慰剂组。试验虽尚未结束,但检查过这些妇女的妇产科医师发现有些宫颈癌前病变已消失。而在正常情况下,癌前病变几乎从不逆转。 Butterworth认为维生索缺乏不一定对全身有影响,它主要影响可以发生问题的细胞,即局部维生素缺乏可导致癌前病变,并继而发展成恶性病变。
Butterworth, MD, of the University of Alabama, USA, conducted a randomized, double-blind clinical trial of 140 young women with precancerous cervical cell changes. The women were divided into 10mg daily folic acid group and placebo group. Although the test is not over yet, gynecologists who examined these women found that some cervical precancerous lesions have disappeared. Under normal circumstances, precancerous lesions almost never reversed. Butterworth believes that the lack of vitiligo does not necessarily affect the whole body, it mainly affects cells that can cause problems, namely, local vitamin deficiency can lead to precancerous lesions, and then develop into malignant lesions.
