查询词典 barrier

BACKGROUND: The copper-superoxide dismutase can not play an effective role in free radical-scavenging in the process of hypoxia or reaeration because of blood-brain barrier, whether the treating effect can be enhanced by chitosan nanoparticles is uncertain.

背景：由于血脑屏障的存在，铜超氧化物歧化酶在临床应用中往往达不到其在体外对中枢神经细胞缺氧、复氧过程中的自由基清除效果。那么能不能利用壳聚糖纳米粒这一种新的基因载体来增强铜超氧化物歧化酶的治疗效果呢？
