dc.description.abstractASYMMETRIC DIMETHYLARGININE - COMPARSION OF CHROMATOGRAPHY AND IMMUNOMETRIC METHODS Objective:Asymmetric dimethylarginine (ADMA) is often discussed in connection with hyperhomocysteinemia and its toxic effect on vessel wall. ADMA concentration is usually measured by HPLC (High Performance Liquid Chromatography) after previous derivatisation. Recently, ELISA (Enzym Linked Immuno Assay) methods for ADMA determination were introduced and ELISA kits are commercially available. Method and Result:The aim of the study was to compare HPLC and ELISA methods for ADMA determination. For HPLC determination we used equipments from Thermo separation product (Florida, USA). After solid-phase extraction on polymer cation-exchange column and the following derivatisation with o-phthaldialdehyde the samples were separated using C18 column (mobile phase 8.7% acetonitril, 50 mmol/l phosphate buffer, pH 6.5) and a fluorescence detector. NG-monomethyl-L-arginine was used as an internal standard. ADMA® ELISA kit, based on a competitive principle, was obtained from DLD Diagnostika, Hamburg, Germany. ADMA was measured in EDTA plasma of 40 healthy blood donors and 40 hemodialysis patients with hyperhomocysteinemia. Conclusion: In spite of different principles both methods showed a very good correlation (r = 0.944, p<0.0001). ELISA...en_US
dc.description.abstractAutorka ve své práci porovnává rizikové faktory aterosklerozy s hladinou ADMA s cílem zjistit sílu prevalence ADMA jako prediktoru úmrtí u hemodialyzovaných pacientů. U pacientů s poruchou funkce ledvin pak porovnává hladiny ADMA před dialýzou a po ní v závislosti na různém typu dialýzy.cs_CZ
