Guanidino compounds in hyperargininemia.
Plasma and cerebrospinal fluid (CSF) concentrations and urinary excretion of guanidino compounds were investigated in a patient with hyperargininemia during the treatment with low-protein diet, oral administration of an essential amino acid mixture and sodium benzoate, or enzyme replacement therapy such as exchange transfusion or erythrocyte transfusion. In the patient, alpha-keto-delta-guanidi...
متن کاملSynthesis of nitric oxide from the two equivalent guanidino nitrogens of L-arginine by Lactobacillus fermentum.
Ten strains of Lactobacillus fermentum that differed in origin converted metmyoglobin to nitrosylmyoglobin [a pentacoordinate nitric oxide (NO) complex of Fe(II) myoglobin] in MRS broth at pH 4.3. Of the 10 strains, L. fermentum IFO 3956 possessed the strongest capacity to convert metmyoglobin to nitrosylmyoglobin. This strain synthesizes NO enzymatically from the two equivalent guanidino nitro...
متن کاملl-Arginine Supplementation and Metabolism in Asthma
L-Arginine, the amino acid substrate for nitric oxide synthase, has been tested as a therapeutic intervention in a variety of chronic diseases and is commonly used as a nutritional supplement. In this study, we hypothesized that a subset of moderate to severe persistent asthma patients would benefit from supplementation with L-arginine by transiently increasing nitric oxide levels, resulting in...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولMetabolic relationship between urea and guanidino compounds as studied by automated fluorimetry of guanidino compounds in urine.
In this automated system for assaying guanidino compounds, the compounds are resolved on an ion-exchange (Dowex 50) column, then reacted with phenanthrenequinone in alkaline solution. This mixture is then acidified and the resulting fluorescence is measured (lambda ex, 305 nm; lambda em, 395 nm). I applied the system to the analysis of urine from control rats and rats given L-canavanine, L-cana...
