Three patients developed methaemoglobinaemia after eating meat contaminated with excessive nitrites. Diagnosis was delayed in the first two mild cases but was promptly made in the third most severely affected case.

nitrate has been the most common chemical contaminant in water resource. this ion is introduced into the water via different ways, but more items of nitrate pollution was connected with farming-based drainage and sewage effluent. in this descriptive-analytical study, groundwater nitrate and nitrite concentrations of 8 wells on dehloran, ilam, iran, were analyzed in 2015 to determine the causes ...

This study determined the reliability of dipstick urinalysis for detection of protein, glucose, blood and nitrites in non-random urine samples from 300 people aged > 50 years attending a health centre for check-up. The gold standards were fasting blood glucose for glucosuria and the sulfosalicylic acid method for urine protein. Microscopic examination of urinary sediment and urine culture were ...

The oxidation of N-hydroxylated compounds may result in production of nitrogen oxides, including nitric oxide (NO). Oxidation may be independent on NO-synthase. Production of nitrites and nitrates via NO from formaldoxime and glyceryl trinitrate was studied and compared. Superoxide ion, ions Fe2+ and Fe3+, methemoglobin and methemoglobin + NADPH + methylene blue, oxyhemoglobin and oxyhemoglobin...

INTRODUCTION Endothelial dysfunction and inflammation play a key role in the development of atherosclerosis. The present study evaluated endothelial function, inflammatory parameters, and carotid intima-media thickness (IMT) in dyslipidemic patients with or without coronary artery disease (CAD). METHODS Metabolic profile and inflammatory parameters were determined in dyslipidemic patients wit...
