为确保甲壳素医用敷料在临床上的安全使用,用甲壳素医用敷料生理盐水浸提液分别对大鼠经尾静脉和小鼠经口的急性毒性试验、家免原发性皮肤刺激试验、溶血试验及豚鼠皮肤致敏试验。发现甲壳素医用敷料生理盐水浸提液经大鼠尾静脉注射,小鼠经口灌胃试验剂量均为5ml·kg-1(相当于800cm2),在观测期内未见明显中毒症状及死亡;家免原发性皮肤刺激试验显示对皮肤无明显刺激作用;溶血试验提示平均溶血率为1.4%,对兔血细胞无溶血作用;对豚鼠皮肤无致敏作用。认为甲壳素医用敷料为一种安全的临床手术敷料替代品。
In order to ensure the safe use of chitin medical dressings in clinic, the acute toxicities of oral administration of chitosan medical dressings saline solution to the tail vein and mice were respectively tested.
