摘要: 目的 研究建立糖尿病足下肢急性缺血模型的方法。方法 30只雄性Wistar鼠腹腔注射STZ(50mg/kg)诱发糖尿病模型,血糖达16.8mmol/L后,再手术结扎股动、静脉及周围血管,造成左下肢急性缺血模型,用激光多普勒(LDPI)测定下肢血流。结果 81.5%大鼠(22只)空腹血糖水平达16.8mmol/L,结扎后1~14d下肢显著性缺血(P<0.05),21d血流基本恢复到术前水平,两侧无明显差异性。结论 Wistar鼠按本方法在3周内可造成糖尿病足急性下肢缺血模型,为研究其创面愈合机理提供了可能。

Abstract: Objective To establish the acute hind limb ischemia on Wistar rat with diabetes mellitus. Methods 30 male Wistar rats were induced by intraperitoneal STZ (50mg/kg) injection, as well as the blood glucose level tested over 16.8mmol/L. The rats were ligated on the left femoral artery, then the blood perfusion on the hind limbs ischemia were measured by LDPI after the operation. Results The fasting plasma glucose level on 22 Wistar rats(81.5%) were kept above 16.8mmol/L, and the hind limb blood perfusion would recover slowly to the level of the right side from 1 to 14 day (p<0.05). There is no distinctly significance on both sides until the 21st day. Conclusion Followed by the above mentioned protocol, the acute hind limb ischemia on the diabetic Wistar rat can be established during 3 weeks, which provided the possibility to investigate the healing mechanism of the diabetic food ulcer.
