[28] The activity of plasma GPx was expressed as units per mL (U/mL) and the activity of erythrocyte GPx as units per grams of hemoglobin (U/gHgb). Serum selenium concentrations were measured by electrothermal atomic absorption spectrometry (ETAAS) using a Varian Spektr AA-800 electrothermal atomic http://www.selleckchem.com/products/Y-27632.html absorption spectrometer.7 Plasma samples were assayed for TAC with an automated biochemistry analyzer (RX Daytona)2 with a commercial total antioxidant status (TAS) kit,2 following the instructions of the kit. The assay[29] is based on the reduction of free radicals (ABTS*+?2,2'�Cazinobis-(3-ehylbenzothiazoline-6-sulfonate)) measured as a decrease of absorbance at 600?nm at 3?minutes by antioxidants. The results are expressed as mmol/L of Trolox equivalents. Data were analyzed using the SPSS computer program.8 Descriptive statistics were used to describe the baseline data of the 2 groups of cats. The Shapiro�CWilk test was performed to test whether the data were normally distributed or not. Results are expressed as means �� standard deviation, unless stated otherwise. Values of selected blood parameters (serum selenium concentration, plasma and erythrocyte GPx, plasma TAC) were compared among groups of cats (4 groups of cats with different stages of feline CKD and healthy cats) using one-way ANOVA and Tukey's HSD posthoc http://www.selleck.cn/products/BKM-120.html test. An unpaired t-test was used to compare ages between the controls and clinical groups of cats (healthy versus IRIS stages I�CIV). Posthoc power analysis using the general linear model/univariate approach also was performed. A value of P? http://www.selleckchem.com/products/chir-99021-ct99021-hcl.html for FeLV/FIV. In addition, 11 healthy cats were excluded because of inability to collect urine samples. Overall, 45 client-owned cats were included in the study. Nineteen healthy cats were included in the control group. The group of cats with CKD consisted of 26 cats. Five cats were classified as stage I, 9 as stage II, 7 as stage III, and 5 as stage IV. The mean age of the healthy cats differed significantly (Table?1) in comparison with the mean age of stages I�CIV CKD cats. Laboratory findings (Table?1) indicated that mean serum creatinine concentrations in individual groups of cats varied according to IRIS guidelines for feline CKD stages I�CIV.[23] In healthy cats, the results of all laboratory parameters, with the exception of platelets, were within normal reference ranges. Results for serum selenium concentration, activity of plasma and erythrocyte GPx, and plasma TAC are summarized in Table?3.
