利用肉毒杆菌素(botulinum neurotoxin)除皱,是一种广为使用的美容治疗方法。然而这种方法必需重复施行注射以维持疗效。美国斯克利普斯研究院的化学家研制出更有效的肉毒杆菌素。它不仅能降低剂量、注射频率以及引发的免疫并发症,也可望降低费用。如果这种杆菌素在动物和人体上试验成功,预计四到六年即可上市。 The use of botulinum neurotoxin for wrinkle removal is a widely used cosmetic treatment. However, this method must be repeatedly administered to maintain efficacy. Chemists at the Scripps Research Institute in the United States have developed more effective botulinum. Not only does it reduce the dose, the frequency of injections, and the resulting immune complications, it can also reduce costs. If this bacteriocin is successfully tested on animals and humans, it is expected to be available four to six years later.
