High performance liquid chromatography (HPLC) with diode array detection (DAD) and electrospray ionization tandem mass spectrometry (ESI/MS/MS) was used to analyze the main components in the methanol extract of Fructus Aurantii (FA) and the metabolites in rat biological samples after oral administration of the methanol extract of FA. There were 31 constituents identified in the extract of FA in...
BACKGROUND Low plasma betaine has been associated with unfavorable plasma lipid profiles and cardiovascular risk. In some studies raised plasma betaine after supplementation is associated with elevations in plasma lipids. We aimed to measure the relationships between plasma and urine betaine and plasma lipids, and the effects of lipid-lowering drugs on these. METHODOLOGY Fasting plasma sample...
BACKGROUND The degree of inflammatory reaction and leucocyte trafficking during acute pyelonephritis has been related to the risk of developing renal parenchymal scarring. Adhesion molecules play a central role in leucocyte recruitment during inflammation. AIMS (1) To determine whether circulating and urinary concentrations of E-selectin and intercellular adhesion molecule 1 (ICAM-1) were abn...
abstract background: in this study our purpose was to determine whether 8 and/or 12 hour urine total protein values correlate with the 24 hour value to confirm the diagnosis of pre-eclampsia. methods: the study population included 70 inpatients with hypertensive disorders of pregnancy. patient's urine was collected over 24 hours with the first 8 hours, next 4 hours, and remaining 12 hours in se...
Cisplatin is a major anti-neoplastic agent which nephrotoxicity is its main side effect and limits its usage in cancer chemotherapy. Reactive oxygen species (ROS) are highly responsible for cisplatin induced nephropathy, so we determined the effects of oral administration of ethanolic olive leaf extract (OLE) as a plant antioxidant on nephrotoxicity of this drug. Material and methods: 21 adult...
PURPOSE Exposure to diisocyanates is a known occupational hazard. One method for monitoring occupational exposure is by analyzing biomarkers in hydrolyzed urine and plasma. The half-life of the biomarkers in plasma is about 3 weeks, and the urinary elimination is divided into one fast (hours) and one slow phases (weeks). Polymorphism in glutathione S-transferase enzymes (GST) is earlier shown t...
OBJECTIVES 1,5-Naphthalene diisocyanate (NDI) is used in the plastic industry as a curing agent. 1,5-Naphthalene diisocyanate is classified as a sensitizing agent. The objective of this study has been to develop biomonitoring methods for the evaluation of exposure to NDI. MATERIAL AND METHODS We obtained blood and urine samples from a group of 20 male workers exposed to NDI. The workers answe...
