background: although lipid lowering agents as statins are used frequently in hyperlipidemic patients as well as patients with cardiac disease, they could have major hepatic side effects, the aim of this study is to evaluate the safety of statins mainly atorvastatin on liver as estimated by liver aminotransferase assay. m aterials and methods: patients with indication of atorvastatin were includ...

Objective(s): This study was to investigate the antihyperlipidemic and antioxidant effect of total flavonoid extract from Actinidia kolomikta (TFAK) in hyperlipidemia induced by a high-fat diet. Materials and Methods: Male SD rats were randomly divided into 6 groups: normal group, model (hyperlipidemic diet) group, hyperlipedemic diet supplemented with TFAK (50, 100 and 200 mg/kg) and simvastat...

background: considering the increasing incidence of coronary artery stenosis and its related complications, the importance of its etiology and inconsistent reports we aimed to determine the relationship between oxysterol, serum levels and severity of coronary atherosclerosis and effect of statins on oxysterol.  methods: a total of 85 patients referred to taleghani hospital, tehran, iran during ...

Lanosterol is a precursor for cholesterol, which synthesized primarily in the liver pathway often described as mevalonate or HMG-CoA reductase pathway. The first two steps (formation of acetoacetyl CoA and mitochondrial generation (S)-3-hydroxy-3-methylglutaryl-CoA) are also associated with oxidation fatty acids.

background: nephrotic syndrome is a disorder that leads to hyperlipidemia. l-carnitine and genistein can effect on lipid metabolism and the syndrome. in the present study, we have delved into the separate and the twin-effects of l-carnitine and genistein on the gene expressions of hmg-coa reductase and ldl receptor in experimental nephrotic syndrome. methods: in this controlled experimental stu...

coronary heart disease is the leading cause of death and disability in adults. the association between acute coronary syndrom (acs) and elevated serum high sensitivity c-reactive protein (hscrp) suggests that chronic inflammation of the coronary arterial wall may play an important role. a number of drugs used in the treatment of cardiovascular disease reduce serum crp. it* is therefore possible...

objective: to review the potential role and specific impact of statin drugs in women with pcos. the evidence for this use of statins in pcos is limited and still under further investigation. materials and methods: a search was conducted using pubmed, dynamed and pubmedhealth databases through october 16, 2016 using the terms polycystic ovary syndrome, pcos, hydroxymethylglutaryl-coa reductase i...

Extensively purified rat liver cytosolic 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase kinase was used to examine the role of ADP in inactivation of HMG-CoA reductase (EC 1.1.1.34). Solubilized HMG-CoA reductase was a suitable substrate for HMG-CoA reductase kinase. At sufficiently high concentrations of solubilized HMG-CoA reductase, reductase kinase activity approached that measur...

It has been previously demonstrated that the enzymic activity of rat liver 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-CoA reductase; EC 1.1.1.34) is modulated in vitro and in vivo by a bicyclic cascade system involving reversible phosphorylation of HMG-CoA reductase and reductase kinase. In the present study, administration of mevalonolactone to rats caused a rapid inhibition of HMG-C...
