纳米抗菌塑料气管插管或套管的体外毒性试验、理化性能及抗菌性能测定显示,纳米抗菌塑料气管导管浸提物未引起小鼠急性毒性反应,各项理化指标均符合医用气管插管或套管的理化标准,对常见的感染菌有较好的抗菌作用[1]。为观察其在体内是否也具有良好的抗菌作用,作者采用随机分组
Nano-antibacterial plastic intubation or cannula in vitro toxicity tests, physical and chemical properties and antibacterial properties showed that nano-antibacterial plastic tracheal catheter extract did not cause acute toxicity in mice, the physical and chemical indicators are in line with medical tracheal intubation or sleeve Tubes of the physical and chemical standards, common bacteria have a good antibacterial effect [1]. To see if they also have good antibacterial activity in the body, the authors randomized
