如果有两种给药方法,一种是注射到血液里去,一种是经颅骨钻孔给药,相信大部分人会选择前者。但遗憾的是,许多新的治疗脑病的方法却不能通过血行给药,因为这些药物会被阻拦无法进入脑。所幸的是,对这种阻拦机制的研究,会使操控这一系统并将药物从体循环直接运送进脑的技术逐步完 If there are two methods of administration, one is to inject into the blood, one is through the skull drilling, I believe most people will choose the former. Unfortunately, however, many new methods of treating encephalopathy can not be administered by blood because these drugs are blocked from entering the brain. Fortunately, the study of this blocking mechanism will lead to the gradual completion of the technology that manipulates the system and delivers the drug directly from the circulation into the brain
