化疗性静脉炎小鼠模型的建立

目的通过静脉注射氟尿嘧啶建立稳定有效的化疗性静脉炎小鼠模型。方法 42只昆明小鼠按照给药浓度随机分为7.5 mg/mL、10.0 mg/mL、12.5 mg/mL,15.0 mg/mL、17.5 mg/mL和22.5 mg/mL共6个实验组和1个对照组。实验组小鼠分别从左侧鼠尾静脉注射0.4 mL不同浓度的氟尿嘧啶溶液,对照组注射0.4mL的生理盐水。给药后第3 d对化疗性静脉炎表现进行分级评价后处死。制作石蜡切片并进行镜下分级。结果随注射氟尿嘧啶剂量的增加,小鼠静脉炎发生率也逐渐增高,350 mg/kg(17.5 mg/mL组)以上剂量组动物出现中毒死亡。300 mg/kg(15.0 mg/mL)剂量组化疗性静脉炎发生率达100%,无动物死亡,出现典型的静脉炎症状,对照组未出现类似变化。结论通过小鼠尾静脉注射300 mg/kg～350 mg/kg剂量范围的氟尿嘧啶可成功建立稳定有效的化疗性静脉炎小鼠模型。

Establishment of Chemotherapy Induced Phlebitis Model in Mice

Objective To establish a stable and effective chemotherapy induced phlebitis(CIP) model in mice by intravenous injection of Fluorouracil.Methods Forty two KM mice were randomly divided into 6 treatment groups and 1 control group.The treatment groups were administrated with Fluorouracil at doses of 7.5 mg/mL,10.0 mg/mL,12.5 mg/mL,15.0 mg/mL,17.5 mg/mL,and 22.5 mg/mL respectively,and each mouse received Fluorouracil by injection of 0.4 mL volume into the left caudal vein.The control received the same volume o...
