Abstract:
Syringa pinnatifolia Hemsl.( SP) is a representative Mongolian folk medicine with the effects of inhibiting Heyi related diseases,clearing heat and relieving pain. It has been used for the treatment of Heyi-induced heart tingling,heart palpitations,upset,insomnia and other symptoms. Total ethanol extract( T) and major fraction( M) of SP have been evaluated its anti-ischemic effects,and the mechanism was related to the regulation of cyclooxygenase( COX)-mediated inflammatory pathway and p53-mediated apoptosis pathway in our previous studies. This study reports the chemical fractionation on M by which to obtain subfractions( I and M_3),and the pharmacological evaluation of M,I,and M_3 against myocardial ischemia in mice. The result showed that I and M reduced the values of LVEDd and LVEDs,significantly increased EF and FS values,increased serum CK-MB and LDH levels in mice,and reduced in inflammatory cells infiltration and collagen deposition in the infarcted myocardial tissue,suggesting that M and I possess the same degree anti-myocardial is chemia equally whereas M_3 has no this effect. Related mechanism studies suggested that I can reduce the expression of COX-1,COX-2 and p53 protein in myocardial tissue in a dose-dependent manner. This study lays the foundation for further chemical segmentation and clarification of pharmacological substance groups,paving the way for the full use and benefits to be use of systematic biological methods to analyze the pharmacological basis of SP against myocardial ischemia.
