Study Data from Urmia University of Medical Sciences Update Knowledge of Atherosclerosis
By a News Reporter-Staff News Editor at Cardiovascular Week -- Fresh data on Cardiovascular Diseases and Conditions are presented in a new report. According to news reporting originating from Orumiyeh, Iran, by NewsRx correspondents, research stated, "Chronic ethanol consumption increases the incidence of cardiovascular disease. The mechanisms underlying ethanol-induced susceptibility to cardiovascular disease continue to be defined."
Our news editors obtained a quote from the research from the Urmia University of Medical Sciences, "This study examines the hypothesis that chronic ethanol consumption plausibly induces vascular wall abnormalities via inflammatory reactions. In addition, it intends to find out whether vitamin E inhibits the abnormalities induced by ethanol in rats' vascular wall. Twenty four male Wistar rats were divided into three groups (n = 8): Control, ethanol (E), and vitamin E treated ethanol (VETE) group. After 6 weeks, the aortic and coronary wall changes, vascular endothelial growth factor (VEGF), alpha-1 glycoprotein and haptoglobin amounts in plasma, C-reactive protein levels(CRP), as well as the amount of aortic IL-6 were evaluated. The results revealed the elevation of polymorphonuclear (PMN) leukocyte in the vascular wall, disorganization of endothelium with ballooning of cells, proliferation of vasa-vasorum with an increase in the IL-6, CRP, as well as a decrease in VEGF and an increase in alpha-1 glycoprotein and haptoglobin in the ethanol group compared to the control group. Significant amelioration of aortic and coronary wall changes, along with the restoration of elevated level of IL6, CRP, and the decreased level of VEGF compared to that of the controls were found in vitamin E-treated animals."
According to the news editors, the research concluded: "These findings strongly support the idea that heavy and chronic ethanol consumption initiates atherosclerosis by inflammatory stress, and that these effects can be alleviated by vitamin E as an anti-inflammatory agent."
