日本研发超级微型胶囊 药效或可放大100倍

2017-11-01 佚名 中国新闻网

据日媒报道,近日,日本东京大学和东京医科齿科大学的科研小组使用氨基酸研发了一种直径仅有3万分之1毫米左右的超级微型胶囊。

据日媒报道,近日,日本东京大学和东京医科齿科大学的科研小组使用氨基酸研发了一种直径仅有3万分之1毫米左右的超级微型胶囊。

据报道,人脑除了成为营养源的葡萄糖等之外,血液中的物质几乎都无法进入其中,在治疗阿尔茨海默病等疾病方面,如何将药物输送到人脑内部一直是一个重大难题。

而使用葡萄糖将这一胶囊的表面覆盖后,脑血管中的特定蛋白质与胶囊的葡萄糖相结合,从而可将胶囊输送到人脑内部。

报道称,科研小组还注意到在空腹状态下特定蛋白质能积极地输送葡萄糖这一特点,并将胶囊用于空腹状态下的实验鼠时,成功地将胶囊输送到了鼠脑内部,其效果达到迄今为止药物的100倍左右。

科研小组认为,如果将药物成分放入这一胶囊的话,可以期待其达到迄今为止所无法达到的疗效。

东京医科齿科大学教授横田隆德指出:“这一胶囊不仅可以在医治老年痴呆症,而且还可以在治疗神经关联的疑难病症以及精神疾病方面成为强有力的武器。”

此外,东京大学特任教授片冈一则表示:“希望将来能研发出可将药物输送到人体任何所需部位的纳米技术。”
