BACKGROUND & OBJECTIVES Many traditional independent risk factors such as diabetes mellitus, hypertension, hypercholesterolaemia, smoking, male sex, old age, etc., contribute to the development of coronary artery disease (CAD). Hyperhomocysteinaemia is an independent risk factor of CAD but the role of plasma homocysteine (Hcy) in high risk patients (> or =(More)
This study is to determine the effect of the natural product parthenolide, a sesquiterpene lactone isolated from extracts of the herb Tanacetum parthenium, on the proliferation of vascular smooth muscle cells (VSMCs). Rat aortic VSMCs were isolated and cultured in vitro, and treated with different concentrations of parthenolide (10, 20 and 30 μmol/L).(More)
Oxidative stress plays a dominant role in the pathogenesis of diabetes mellitus. Bcl-2 gene has close connection with antioxidant stress destruction in many diseases including diabetes. Carvedilol, an adrenoceptor blocker, also has antioxidant properties. To study the effect of carvedilol on the antioxidant status in diabetic hearts, we investigated(More)
The aim of this study was to study the relationship between plasma homocysteine (Hcy), folic acid, vitamin B12 and early coronary artery disease (early-CAD) and high coronary risk factors. The plasma Hcy levels of 58 cases with early-CAD and 31 subjects without CAD were measured using high-performance liquid chromatography (HPLC) with fluorescence(More)
Several studies have shown that simvastatin induces apoptosis in a variety of cell lines including vascular smooth muscle cells (VSMCs), but the exactly mechanisms involved in it is not very clear. The aim of this study was to investigate the mechanisms and signal pathways involved in apoptosis induced by simvastatin. When exposed to 30 microM simvastatin,(More)
The risk for cardiovascular disease is significantly high in diabetes mellitus. Oxidative stress plays a dominant role in the pathogenesis of diabetes mellitus. Bcl-2 gene has a close connection with antagonizing oxidative stress destroy in many diseases including diabetes. Carvedilol, an adrenoceptor blocker, also has antioxidant and free radical scavenger(More)
1. The leucocyte-mediated inflammatory response plays a pivotal role in ischaemia-reperfusion injury. P-Selectin and CD11b are important mediators for the recruitment of leucocytes into the endothelium. However, the time-course of changes in P-selectin and CD11b expression during reperfusion is not defined. Magnesium has been shown to have a protective role(More)
OBJECTIVE To investigate whether coagulation factor VII (FVII) polymorphisms play a role in the pathogenesis of coronary artery disease (CAD) and/or myocardial infarction (MI) in a series of Hans. METHODS The Arg(353)Gln and HVR4 polymorphisms of FVII gene were determined in 374 patients undergoing selective coronary angiography by PCR and restriction(More)
AIM To determine the protective effect and influence on NOS expression of Montelukast sodium--a leukotriene antagonist on myocardial necrosis in rats. METHODS Myocardial ischemia and necrosis were induced in rats by isoproterenol (2 mg.kg-1, s.c., qd for 2 d). Serum activity of LDH, CK, MDA, NO content in myocardium and scope of myocardial necrosis were(More)
OBJECTIVE To investigate the effect of long-term administration of fluvastatin on improvement of ventricular remodeling of rats after myocardial infarction and its mechanism. METHODS Sprague-Dawley rats were subjected to ligation in anterior descending branch of coronary artery and treated with fluvastatin (20 mg.kg(-1) d(-1)) or distilled water for 8(More)
