Introduction: Liver disorders in patients with type 2 diabetes (T2D) are mostly associated with higher serum levels of liver enzymes. This study aimed to investigate the effect of nitrate administration on the serum levels of alanine amino transferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) in rats with T2D. Materials and Methods: In this study, 24 male Wistar ra...
Introduction: As a nitric oxide (NO) donor, nitrate administration improves renal function in male animals. This study aims to determine the effects of chronic administration of different doses of nitrate on kidney function in normal adult female rats by measuring serum urea and creatinine and assessing the estimated glomerular filtration rate (eGFR). Materials and Method: Two-month old female ...
Introduction: High prevalence of liver disorders has been observed in postmenopausal women. This study aims at determining the effects of long-term, low-dose nitrate administration on serum levels of liver enzymes, including aspartate aminotransferase (AST), alkaline phosphatase (ALP), and alanine aminotransferase (ALT) in ovariectomized rats. Materials and Methods: Female Wistar rats were divi...
OBJECTIVE To assess and compare serum nitrate and nitrite levels in patients with ankylosing spondylitis (AS), rheumatoid arthritis (RA), and osteoarthritis (OA). METHODS Thirty five patients with RA, 32 patients with AS, and 36 patients with OA were entered into this study. In addition, 30 healthy volunteers acted as a control group. Concentrations of nitrate and nitrite in serum were determ...
BACKGROUND Insulin resistance, which is associated with an increased risk of cardiovascular morbidity and mortality, has become a leading nutrition problem. Inorganic nitrate enriched in spinach has been demonstrated to reverse the pathological features of insulin resistance and endothelial dysfunction. However, the effects of a direct intake of nitrate-enriched spinach on insulin resistance an...
BACKGROUND Nitric oxide is an important mediator in inflammatory and autoimmune-mediated tissue destruction and may be of pathophysiologic importance in inflammatory bowel disease. We studied whether serum levels of nitrate, the stable end-product of nitric oxide, are increased in active Crohn's disease or ulcerative colitis, in comparison with quiescent disease and healthy controls. The settin...
We report a simple, enzymatic, end point method for determining nitrate in serum and urine with use of nitrate reductase from Aspergillus sp. (EC 1.6.6.2). The decrease in absorbance at 340 nm as a result of the oxidation of beta-NADPH is measured. We used FAD as a supplementary electron carrier and added an internal standard to avoid interference from possible inhibitors of the enzymatic react...
Abstract Background and objectives: Smokers are exposed to significant quantities of ROS (Reactive Oxygen Species) and The Level of Nitric Oxide (NO), the primary vasodilator produced by endothelial cells, is changed by cigarette smoking. Cigarette smoking is associated with impaired endothelium-dependent vasodilatation and cardiovascular disease (CVD). The aim of this study is to determine the...
This study is designed to evaluate the roles of oxidative and nitrosative stress in serum and cerebrospinal fluid (CSF) of relapsing remitting multiple sclerosis (RRMS) patients. Oxidative stress markers thiobarbituric acid reactive substances (TBARS), 8-epi-PGF2α, conjugated diene and nitrosative stress markers nitrotyrosine, nitrit-nitrate were analysed in serum and CSF of 20 newly diagnosed ...
Nitrate is a wide spread contaminant of ground and surface water. The source of nitrate in the ground water may be from run off or seepage from fertilized soil, municipal or industrial waste water, land fills, septic system, urban drainage or decaying plants. Human and animal systems are affected severely on nitrate exposure. The study was to investigate the effect of dietary nitrate exposure o...
