Development of flow injection analysis (FIA) is reported for determination of total antioxidant capacity of alcoholic beverages (wines and spirits) by bienzymatically produced ABTS + and electrochemical detector using interdigitated gold electrode (IDE). The method is based on biamperometric measurements using ABTS jABTS redox couple. During the analysis,(More)
BACKGROUND AND AIMS Despite recent advances in surgical techniques and intensive care management, infectious complications and sepsis remain significant problem after abdominal surgery. Therefore, inflammatory parameters were looked for that could help achieve an early and more reliable diagnosis of postoperative infections. C-reactive protein (CRP) is a(More)
Concentrations of parent pesticide and corresponding diethylphosphorus metabolites in blood serum and urine were investigated in persons who had ingested a concentrated solution of organophosphorus pesticide chlorpyrifos. The organophosphate poisoning was indicated by a significant depression of blood cholinesterase (EC and EC activities.(More)
AIM To assess diagnostic value of perioperative procalcitonin (PCT) levels compared to C-reactive protein (CRP) levels in early detection of infectious complications following colorectal surgery. METHODS This prospective observational study included 79 patients undergoing elective colorectal surgery. White blood cell count, CRP, and PCT were measured(More)
To investigate the risk for the development of urolithiasis in 30 children with urolithiasis, 36 children with isolated hematuria, and 15 healthy control children, 24-h urinary excretion of calcium, sodium, oxalate, citrate, sulfate, phosphate, magnesium, urate, chloride, ammonium, and glycosaminoglycans was determined and urine saturation for calcium(More)
BACKGROUND Ischemia-modified albumin (IMA) is a potentially valuable biochemical marker of myocardial ischemia. The aim of our study was to define the kinetics and to determine the diagnostic value of IMA in detection of myocardial ischemia by using a model of exercise-stress induced transitory ischemia. METHODS The study included 43 consecutive patients(More)
Magnesium is one of the most important factors for regulation of inflammatory response as well as muscle function, and COPD is a multicomponent disease characterized by abnormal inflammatory response of the lungs with systemic muscle dysfunction. Because polymorphonuclear (PMN) cells are significantly represented in the pathogenesis of COPD, concentrations(More)
BACKGROUND The aim of this study was to investigate the effect of low-pressure pneumoperitoneum and pentoxifylline, a methylxanthine derivative, in the prevention of injury caused by free oxygen radicals generated during CO(2 )pneumoperitoneum. METHODS Twenty-eight rabbits were allocated randomly to 4 groups. Control group rabbits (group 1) were subjected(More)
The presence and elimination rate of phosalone and its diethylphosphorus metabolites in blood serum and urine were studied in persons who had ingested a concentrated phosalone solution. Phosalone was detected only in serum samples. As it was rapidly hydrolysed and eliminated from the body, its diethylphosphorus metabolites were a more sensitive indicator of(More)
The urinary excretion rates of diethyl phosphate and diethyl phosphorothioate and changes in blood cholinesterase activities were studied in fifteen persons self-poisoned either by the organophosphorus pesticide quinalphos (twelve persons) or by chlorpyrifos (three persons). The organophosphate poisoning was always indicated by a significant depression of(More)
