Effects of Tanyu Tongzhi recipe on hemorheology, blood lipid and inflammatory factors in rats with mycardial ischemia-reperfusion injury and hyperlipidemia / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the influence of Tanyu Tongzhi (TYTZ) recipe on chemorheology, blood lipid and inflammatory factors of hyperlipidemia and myocardial ischemia-reperfusion injury in rats.</p><p><b>METHOD</b>Sixty SD male rats were divided into 5 groups randomly, sham-operated group, model group, high dose group of reproduced by ligation of left descending artery for 30 min followed by releasing the TYTZ and low group of TYTZ. The model of MI/RI injury of the myocardium was ligation for 2 hours in rats. Serum contents of CHO, TG, HDL-L, LDL-L and whole blood viscosity, plasma viscosity and ICAM-1, TNF-alpha, IL-10 were measured after myocardial reperfusion injury.</p><p><b>RESULT</b>Compared with sham-operated group, the levels of CHO, TG, LDL-L, whole blood viscosity (1.0,3.0) plasma viscosity and the contents of ICAM-1 were significantly higher, however, HDL-L, IL-10 levels were lower in model group (P < 0.01 and P < 0.05). CHO, TG, whole blood viscosity (1.0, 3.0, 30) and expression of ICAM-1, TNF-alpha were obviously lower in low group than the model group (P < 0.01 and P < 0.05).</p><p><b>CONCLUSION</b>The TYTZ recipe can relieve reperfusion injury through regulating blood lipid, improving hemorheological characteristic and inhibiting inflammatory reaction.</p>
