We describe a liquid-chromatographic assay for cyclosporine (CyA) and four of its metabolites in blood. The method is sensitive and specific for this drug and its metabolites. The use of flow programming shortens total chromatographic run time to 30 min, resulting in acceptable separation of metabolites at a lower flow rate and yielding narrower peaks for CyA and the internal standard at the hi...

This study investigated the effect of Rumex Sc (commercial product which includes of Saccharomyces cervisiae, saponin and essential oils) on rumen fermentation, blood glucose, urea, milk yield and milk composition. Animals were offered a basal diet containing alfalfa hay (15.5%), corn silage (24%), beet pulp (7%) and concentrate (53.5%). Additionally, Rumex Sc was included in the experimental d...

We assessed the reproducibility, recovery, and stability of several circulating metabolites--glucose, pyruvate, lactate, alanine, glutamate, glutamine, 3-hydroxybutyrate, acetoacetate, and glycerol--in the presence of sulfosalicylic acid (SSA), which was used to deproteinize blood. The assays, which involved reactions linked to NADH/NAD+, were carried out at 37 degrees C and measured at 355 nm ...

The aim of this study was to investigate the effects of ethanolic extract of the whole plant of Phyllanthus rheedii wight P.rheedii as antihyperglycemic, antihyperlipidemic and antioxidant effect in streptozotocin (STZ) induced diabetic rats. Male Wistar rats were administered P.rheedii (250 mg/kg) orally for 21 days and blood glucose level was measured weekly. At the end of 21 days, the serum ...

BACKGROUND Phthalates may pose a risk for perinatal developmental effects. An important question relates to the choice of suitable biological matrices for assessing exposure during this period. OBJECTIVES This study was designed to measure the concentrations of phthalate diesters or their metabolites in breast milk, blood or serum, and urine and to evaluate their suitability for assessing per...

Phthalates are environmental chemicals widely used in consumer and personal care products. In this study, we examined associations of urinary phthalates with blood pressure, triglycerides, and lipoproteins in children and adolescents, performing a cross-sectional analysis of a subsample of US children 6 to 19 years of age who participated in the National Health and Nutrition Examination Survey ...
