BACKGROUND Antiplatelet drugs are effective in preventing recurrence of atherosclerosis in type 2 diabetic patients. However, the efficacy and usefulness of 2 different antiplatelet drugs, aspirin and cilostazol, in the progression of carotid intima-media thickening are unknown. METHODS AND RESULTS To compare prevention by cilostazol and aspirin of progression of atherosclerosis, we conducted...

Artery calcification is a well-recognized predictor of late atherosclerotic complications. In the intima media, calcification starts with apoptosis of vascular smooth muscle cells (VSMCs) and the release of calcifying matrix vesicles with diameter of 0.5-15 μm that can be observed microscopically. In complicated plaques, calcification is generally less frequent. Calcifying vesicles are released...

Histopathological studies were made on 9 necropsy specimens of ductus arteriosus with hypoplastic left heart syndrome and I with rubella syndrome. A control group of 40 normal specimens were also studied. In the 17th week of gestation, ductus arteriosus was composed of few elastic fibers, a thick continuous internal elastic lamina and a wide hypocellular area. In the 8th month of gestation, the...

Objective(s): Atherosclerosis is a chronic immune-inflammatory disease that generally leads to ischemic heart disease. Ghrelin has several modulatory effects on cardiovascular system. In this study, we investigated the effect of ghrelin on aortic intima-media thickness, size and the number of adipocyte cells in obese and control mice. Materials and Methods:This study was conducted on 24 male C...

The aim of this study was to determine the changes in carotid artery intima-media thickness as measured by B-mode ultrasound in postmenopausal women receiving hormone replacement therapy (HRT) or not. One hundred and fifty-nine healthy postmenopausal women aged 45-65 years were recruited from our menopause clinic. All the selected women were free of cardio-vascular diseases and had no cardio-va...

Positioning a silicone collar around the rabbit carotid artery induces a smooth muscle cell-rich intimal thickening. We investigated the localization of inducible nitric oxide synthase (iNOS) during thickening of the intima, the effect of iNOS inhibition on intimal thickness, and the effect of oxidized LDL (ox-LDL) on iNOS expression in the vessel wall. Collars were positioned for 18 hours or f...

conclusions la increases the risk of cva and dementia. the la pathology is unknown. the epidemiological studies revealed the age, diabetes, smoking and atherosclerosis are related with la. our findings showed that cimt as an atherosclerosis marker was higher in la patients than control group. results totally 200 patients were studied, 102 in normal group and 98 in ila group. the mean age of pat...

The platelet glycoprotein (GP) IIb/IIIa receptor antagonist appears to reduce the need for revascularization after coronary angioplasty. However, since the effect of GP IIb/IIIa receptor antagonist on the in-stent neointimal thickening has not been clarified, we examined it in the canine model. The beagle dogs were assigned to the control (n=7) or the GP IIb/IIIa receptor antagonist FK633 group...
