Hydro-ethanolic Extract of Portulaca oleracea Affects Beta-adrenoceptors of Guinea Pig Tracheal Smooth Muscle
The stimulatory effect of the extract of Portulaca oleracea (P. olerace) on β-adrenoceptor of tracheal smooth muscle was examined. To examine β-adrenoceptor stimulatory effect, concentration response curve to isoprenaline was obtained in pre-contracted tracheal smooth muscle in the presence of three concentrations of aqueous-ethanolic extract, propranolol and saline. Values of EC50 (the effecti...
متن کاملInflammation and Vascular Calcification Causing Effects of Oxidized HDL are Attenuated by Adiponectin in Human Vascular Smooth Muscle Cells
The role of oxidized high-density lipoprotein (oxHDL) and the protective effects of adiponectin in terms of vascular calcification is not well established. This study was conducted to investigate the effects of oxHDL with regards to inflammation and vascular calcification and to determine the protective role of adiponectin in attenuating the detrimental effects of oxHDL. Cell viability, mineral...

متن کاملEffect of Oxidized Low Density Lipoprotein on the Expression of Runx2 and SPARC Genes in Vascular Smooth Muscle Cells
Background: Vascular calcification is an important stage in atherosclerosis. During this stage, vascular smooth muscle cells (VSMC) synthesize many osteogenic factors such as osteonectin (encoded by SPARC). Oxidative stress plays a critical role in atherosclerosis progression, and its accumulation in the vascular wall stimulates the development of atherosclerosis and vascular calcification. The...
متن کاملبررسی تاثیر اسیدالائیدیک بر بیان ژن استئونکتین در سلولهای عضلهی صاف دیوارهی رگها
Background and Objective: Atheroma formation and progression of atherosclerosis are dependent on the expression of bone matrix proteins and regulatory factors such as osteonectin in the vessel walls. Studies have shown that consumption of Trans fatty acids increase risk of cardiovascular diseases. In this study, the effect of elaidic acid on osteonectin gene expression as one of the vascular ca...
