Abstract:
AIM:To study the role of Rhodiolae rosae in post myocardial infarction angiogenesis and its effect on extracellular regulated kinases(ERK 1/2). METHODS: The experimental myocardial infarction was made by ligation of rat left anterior descending coronary artery,and then divided into Rhodiolae group and saline group.The sham operation group and normal group were also made as control one.On the first,the 4th,the 7th and the(14th) day after the operation,rats were sacrificed and infarcted border tissue or normal tissue were used to test VEGF receptor Ⅱ and CD34 expression level and ERK 1/2 activity level. RESULTS: ERK 1/2 activity level from the first to the 4th day,VEGF receptor Ⅱ and CD34 expression level from the 4th to the 14th day after the operation,were all higher in the Rhodiolae group than that in the saline group. CONCLUSION: Rhodiolae rosae can elevate ERK 1/2 activity which was related to and prior to its angiogenic effect.
