2017-06-16 Drug that creates a ‘real suntan’ could prevent cancer 新药让你无需担忧皮肤癌就“晒出”小麦色

文字稿

科学家们研发出了一种新药，该药物不仅能模拟太阳光晒黑皮肤的过程，还可以让使用者免受紫外线辐射的影响。通过一系列对皮肤样本及实验鼠的测试，科学家们发现该药令皮肤产生了一种呈棕色形态的黑色素。证据显示，就连在阳光下也晒不黑的红发人士们也能尝试这种药物。这支来自麻省总医院（Massachusetts General Hospital）的科研团队希望他们的发现可帮助人们预防皮肤癌，甚至减缓皮肤衰老的过程。请听报道。

The secret to sun-kissed skin is melanin. When the Sun’s blistering rays hit your skin, they cause damage that can lead to cancer. So the skin throws up a protective barrier of brown melanin. It’s the body’s own sunblock and absorbs dangerous UV radiation.

The new drug, developed at Massachusetts General Hospital, is rubbed into the skin. It stimulates the same tanning effect just without the damage. The researchers’ goal is to give people a natural tan that protects against UV and cuts skin cancer rates.

The drug could allow those with the palest of skins to get a safe tan. But whether you’re ginger, blonde, or brunette, you’re in for a wait. The researchers want to perform more safety tests before bottles of real tan reach the shops.
