Reaction of uric acid with peroxynitrite and implications for the mechanism of neuroprotection by uric acid.
Peroxynitrite, a biological oxidant formed from the reaction of nitric oxide with the superoxide radical, is associated with many pathologies, including neurodegenerative diseases, such as multiple sclerosis (MS). Gout (hyperuricemic) and MS are almost mutually exclusive, and uric acid has therapeutic effects in mice with experimental allergic encephalomyelitis, an animal disease that models MS...
متن کاملSerum uric acid levels during leprosy reaction episodes
Background. Leprosy reactions are acute inflammatory episodes that occur mainly in the multibacillary forms of the disease. The reactions are classified as type 1 (reverse reaction) or type 2 (erythema nodosum leprosum). Leprosy-associated oxidative stress has been widely demonstrated. Several recent studies have shown uric acid (UA) to have antioxidative effects under pathologic conditions. Th...
متن کاملUric Acid Analysis with Uricase
Results with two ultramicro methods for plasma uric acid analysis with uricase are described: a crystal violet (gentian violet) method, modified from an automated procedure by Gochman and Schmitz [C/in. Chem. 17, 1154 (1971)] and adapted to manual analysis, and a polarographic oxygen-sensing system (Beckman Instruments,Inc.).The coefficientof variation (CV) for the crystal violet method varied ...
متن کاملThe association of uric acid with leukoaraiosis
Objective To explore the possible correlation between uric acid levels and leukoaraiosis (LA). Methods This cross-sectional study enrolled patients who presented with some neurological discomfort (e.g. dizziness, headache, mild cognitive impairment). Potential demographic and clinical risk factors associated with LA, including sex, age, hypertension, diabetes mellitus, smoking, alcohol consumpt...
متن کاملSub-ppm determination of uric acid using a sensitive kinetic-catalytic reaction system
A sensitive and selective kinetic-spectrophotometric method was developed for the determination of trace amounts of uric acid. The method is based on the inhibitory effect of uric acid on the oxidation of Janus Green by bromate in the presence of sulfuric acid. The reaction was followed spectrophotometrically by measuring the absorbance at 518 nm using the fixed-time method. Under optimum exper...
