Pumpkin Skin May Scare Away Germs
南瓜皮可“吓跑”病菌
ScienceDaily (Oct. 29, 2009) — The skin of that pumpkin you carve into a Jack-o'-Lantern to scare away ghosts and goblins on Halloween contains a substance that could put a scare into microbes that cause millions of cases of yeast infections in adults and infants each year. That's the conclusion of a new study.
ScienceDaily(2009年10月29日) -在万圣节人们用南瓜雕刻成南瓜灯来吓走鬼怪,一项新的研究发现,南瓜皮含有的一种蛋白,也有“威慑”作用,它能够把每年引起数百万成人和婴儿酵母感染的微生物吓跑。
In the study, Kyung-Soo Hahm, Yoonkyung Park and colleagues note that some disease-causing microbes are becoming resistant to existing antibiotics. As a result, scientists worldwide are searching for new antibiotics. Past studies hinted that pumpkin, long used as folk medicine in some countries, might have antibiotic effects.
在这项研究中,Kyung-Soo Hahm及其同事指出,一些致病微生物正变得对现有抗生素有耐药性,因此,世界各地的科学家都正在寻找新的抗生素。过去的研究提示,长期以来在一些国家作为民间药物的南瓜,可能有抗生素作用。
The scientists extracted proteins from pumpkin rinds to see if the proteins inhibit the growth of microbes, including Candida albicans (C. albicans). That fungus causes vaginal yeast infections, diaper rash in infants, and other health problems. One protein had powerful effects in inhibiting the growth of C. albicans, in cell culture experiments, with no obvious toxic effects. The pumpkin protein could be developed into a natural medicine for fighting yeast infections in humans, the report suggests. The protein also blocked the growth of several fungi that attack important plant crops and could be useful as an agricultural fungicide, they add.
研究小组对南瓜外皮进行了蛋白提取,观察这些蛋白在抑制微生物生长方面的作用,包括白色念珠菌(C. albicans),这种真菌引起阴道酵母感染、婴儿尿布皮疹以及其他健康问题。有一种蛋白在细胞培养试验中表现出对白色念珠菌生长有强抑制作用,而无明显毒性。该研究指出,南瓜蛋白能够被开发成抗酵母菌感染的天然药物,该蛋白还可抑制一些可侵害重要农作物的真菌,可以用来作农业杀菌剂使用,他们补充说。 http://www.dxy.cn/bbs/post/view?bid=116&id=15846370&sty=1&tpg=3&age=0 |
