A lyophilized serum chemistry reference standard containing constituents in the “abnormal” range has been evaluated for use as a proficiency standard. The findings indicate that it is a satisfactory material for such use and as a reference standard, provided that it is used in accordance with the manufacturer’s directions. Interferences contributing to inaccurate results in the analysis of bili...

We report the case of a 51-year-old patient with a history of liver cirrhosis, who presented with jaundice (total bilirubin 50 mg/dl [855 µmol/l], direct bilirubin 20 mg/dl [342 µmol/l]) and life-threatening hypophosphataemia (serum phosphate 0.5 mg/dl [0.16 mmol/l]), accompanied by inappropriate phosphaturia. The patient also manifested hypouricaemia (serum uric acid 1.7 mg/dl [101 µmol/l]) wi...

OBJECTIVES Crocin bleaching assay (CBA) is a new method for determination of antioxidant capacity. In CBA, addition of hydrogen to the conjugated double bonds of crocin results in reduction of crocin and increase in the absorbance at 440 nm, which is considered as a measure of antioxidant potential. Here CBA method was set up using di-gentiobiosyl crocin or α-crocin from Iranian saffron. Then, ...

The present study was carried out to evaluate the hepatoprotective and antioxidant effect of the methanol extract of Eupatorium ayapana (MEEA) (Family- Asteraceae) leaves in Wistar albino rats. The different groups of animals were administered with carbon tetrachloride (CCl4) at 72 h interval.  The MEEA at 100, 200 and 300 mg/kg and silymarin 25 mg/kg were administered to the CCl4 treated ...

background: this study aims to evaluate the efficacy of silybum marianum seeds (smss) on blood biochemical profile of broiler chickens contaminated with aflatoxin b1 (afb1).  methods: combinations of three levels of afb1 (0, 250 and 500 ppb) with three levels of smss (0, 0.5, and 1.0 %) were incorporated into the basal diet (corn and soybean meal). the effect of nine experimental treatments was...

Background and Aims: Six sigma is the latest version of total quality management. It is quantitative goal for process performance. With increasing demands for improved accuracy and reliability of the results, Six Sigma is gaining increased visibility in the clinical laboratory process outcomes. The aim of study was to evaluate the quality of analytical phase performance in a clinical biochemist...

It has been suggested that achieving a chromogenic endpoint with an absorbance read at 600 nm or greater will reduce the degree of spectral interference in many colorimetric methods. We have examined a uricase/peroxidase-based system utilising a novel oxygen acceptor (azure-D2) as chromogen which produces a chromophor with an absorbance which can be measured at 600 nm (Synermed). Results (media...
