Selenium is a trace element, essential in small amounts, but it can be toxic in larger amounts. Levels in the body are mainly dependent on the amount of selenium in the diet, which is a function of the selenium content of the soil. Humans and animals require selenium for normal functioning of more than about 30 known selenoproteins, of which approximately(More)
The pharmacology, efficacy, dosage, adverse effects, and economics of anti IgE (omalizumab) are discussed. Omalizumab is the generic name for the human/murine chimeric (recombinant humanized) monoclonal IgG antibody. Anti-IgE prevents IgE from attaching to effector cells, and thereby blunts IgE-mediated inflammatory responses. After subcutaneous(More)
A new and simple flame atomic-absorption spectrometric (FAAS) method is proposed for simultaneous determination of iron and copper in children's sera. It is based on single-step sample pretreatment (deproteinization with 3 mol L-1 HCl, ratio 1:1) and single-step calibration using 1.5 mol L-1 HCl standard. During method's optimization a short multifactorial(More)
The aim of this study was to test the hypothesis that glutathione- S-transferase (GST) genotypes were associated with COPD. GSTP1, GSTM1 and GSTT1 genotypes were determined by DNA methods and GST activity spectrophotometrically in older male Caucasian Croats (non- -smokers, ex-smokers, and smokers) with stable COPD (n = 30) and sex/age matched controls (n =(More)
In an attempt to provide a reliable status of metal ions in children, new methods of analysis of children's sera are proposed. New flame atomic-absorption spectrometric (FAAS) methods are simple, cost- and time-effective and, above all, labor-, reagent- and sample-saving. Two methods were suggested: method A for simultaneous determination of Cu and Zn from(More)
Results of determination of circulating histamine releasing autoantibodies using histamine release urticaria test in 12 children (aged 3 to 18 years, mean age 8.5 years; 7 female and 5 male) with chronic urticaria are presented. Standard work-up including detailed history, allergy testing and routine laboratory findings did not disclose any plausible cause(More)
