ABSTRACT
AIM:
To explore the dynamic changes of ET,NO,SOD and MDA in atherosclerosis obliterans(ASO) rabbits,as well as the effects of Tongxinluo Capsule(Radix et Rhizoma Ginseng,Hirudo,Scorpio,Eupolyphaga seu Steleophaga,etc.)(TXL) and the candidate mechanisms.METHODS:
Rabbits were randomly divided into 7 groups sham,model,TXL(0.8,0.4,0.2 g/kg),Tongsaimai tablet(0.8 g/kg) and Laishike((0.002 g/kg)).The animal model of ASO was established with a combined method of mechanical trauma,immunologic injury and high fat fodder feeding.Rabbits were administrated the drugs for 8 weeks after surgery.The levels of ET,NO,SOD and MDA were determined at the time points below pre-experiment,pre-drug administration,4 weeks after drug administration,8 weeks after drug administration,12 weeks after drug administration.The histopathological changes in iliofemoral artery were examined after opacification.RESULTS:
TXL significantly extenuated the decrease in the caliber of the iliofemoral artery of the injured hind limb and decreased MDA content while increased SOD activity and NO content in serum.CONCLUSION:
TXL might show effects on improving endothelial cell dysfunction,clearing free radicals and antagonizing lipid peroxidation,which might be the candidate mechanisms for the prevention and treatment of TXL for ASO.
