Lemons give new twist to contraception

  Australian scientists believe they have rediscovered an effective use for lemon juice -- as a contraceptive and also a killer of the AIDS virus.

  Reproductive physiologist Roger Short, from the University of Melbourne's obstetrics department, said a few drops of lemon juice can be a cheap, easy-to-use solution to protect women from both HIV and pregnancy.

  The juice should be squeezed onto a piece of sponge or cotton wool and placedsintosthe vagina before sex, he said.

  "We can show in the lab that lemon juice is very effective in immobilising human sperm and also very effective in killing HIV," Short told Australian Broadcasting Corp television in a science programme to be shown later on October 10.

  He said lime juice, which has similar acid levels, can also be used, with both fruits often freely available in poor countriesswherescontraception is hard to come by.

  Short said laboratory tests found not only does lemon juice kill sperm, it also kills the AIDS virus itself.

  Short said using lemon juice as a contraceptive was not a new idea but it had fallen by the wayside over the years.

  "This has been used for hundreds of years and we've just forgotten about it," said Short, who is planning to conduct some field trials in Thailan

澳洲科学家宣布柠檬汁可避孕抗艾滋

  澳大利亚科学家最近宣布,他们发现了柠檬汁的新用途——既可作避孕外用药又可杀死艾滋病病毒。

  据墨尔本大学产科系生理学家索特称,一点点廉价的柠檬汁就可以帮助妇女避孕和防止HIV病毒,而且用法简单,只要用海棉吸一点柠檬汁,在性交前涂于阴部便可。索特在接受当地电视台访问时称,他们在实验室里发现柠檬汁对固定人类精子有非常显著的效果。他还说,只要酸度和柠檬汁相似的果汁都可有相同的功效。而且,实验还显示,这些果汁更可以杀死HIV病毒。因此,索特认为这个方法很值得在穷困国家推广。目前,他打算首先在泰国生产一些试验性的产品。

  索特还说:“其实,用柠檬汁避法已经有几百年历史,只是我们已把它忘了。”
