研究:黄金或可用于癌症治疗 减少化疗副作用

2017-08-07 17:36:37   

中国日报网8月7日电(高琳琳) 据英国《独立报》网站8月7日报道,德国《应用化学》周刊近日刊登的一项最新研究表明,黄金不仅有望应用于癌症治疗,而且能够减少化疗产生的副作用。

来自英国爱丁堡大学的科学家将嵌有金纳米粒子的化学装置植入斑马鱼的大脑,以此证明了这种装置可以被用于动物活体。虽然该疗法还没有在人体上得到验证,但这种治疗手段能够精确作用于病变细胞而不损伤健康组织,在未来有望减少化疗手段所产生的副作用。

此外,金作为一种安全的化学元素,还能够加速化学反应。研究人员发现了金的一些特性,使其催化功能在不产生任何副作用的情况下被用于疾病治疗。

英国癌症研究所(Cancer Research UK)爱丁堡中心的阿西埃·温西蒂-布罗切塔博士介绍说:“我们发现了金的新特性,我们的发现表明可以通过这种金属安全地在肿瘤内部释放药物。”

研究人员希望有朝一日,医生可以通过手术将这种装置直接植入肿瘤,在肿瘤内部激活化疗,减少对健康器官的副作用。

癌症研究所高级科学信息主任艾因·麦卡锡博士表示,通过开发新的更好的抗癌药物可以改善癌症疗法,减少副作用,尤其有助于改进对脑瘤和其他难以治疗的癌症的治疗方法。下一步就要看这种疗法是否能够安全地用于人体,观察其长期和短期副作用,判断它是不是一种更好的癌症治疗方法。
