Objective: To observe the myocardial protective effect and related mechanism of the Tiaozhi Tongluo capsule (TZTL). Method: MIRI model combined with hyperlipemia was established
56 male Wistar rats were divided into following seven group:hyperlipemia group
normal group
sham group without hyperlipemia
Atorva statin group
TZTL 8.64
4.32
2.16 g·kg-1·d-1 group.After feeding of high fat diet for 4 weeks
the drug intervention was carried out
then the left arteria coronariia was legated for 30 min
following reperfusion for 24 hours. At the end of the experiment
the blood and myocardial homogenate samples were collected for measurement of malondialdehyde (MDA)
superoxide dismutase (SOD)
catalase (CAT) and glutathione peroxidase (GSH-Px) for blood lipids
cardiac enzymes[lactic clehydrogense(LDH)
creatine kinase isoenzyme(CK-MB)]. Result: The blood lipids
cardiac enzymes and MDA levels were significantly increased and antioxidant enzyme content decreased obviously in model group. All treatment groups could decrease the cardiac enzymes and MDA levels
and increase the SOD
CAT and GSH-Px levels. Conclusion: The TZTL can reduce the free radicals agrregation and improve the effectof antioxidase.
