A fast, clean and easy to automate flow injection-pervaporation method for the determination of ethanol in different beverages using density measurements is proposed. The method is based on separation of the ethanol from the sample using a pervaporation module; the analyte being collected in water as acceptor liquid. The density of this water-alcohol mixture is measured at the detector. After o...

Introduction: Walnut leaf contains large amounts of antioxidants, phenolic compounds and flavonoids and the beneficial effect of these compounds in the treatment of diabetes has been shown. This study investigated the effect of cyclohexane and ethanol extract of walnut leaf on activity of sorbitol dehydrogenase (SDH) enzyme. Methods: Fifty- six adult male Sprague-Dawley rats were divided into s...

a flow injection system is reported for the determination of fluoride based on its effects on the fluorescence intensity of al-morin complex at ph 3.0 in ethanol-warn mixture. the effect of important parameters such as excitation and emission wavelengths, ph, reagents concenkations, flow rate of the carrier stream, sample injection volume, time of measurepent and interferences are reported. cat...

The development of tolerance to alcohol with chronic consumption is an important criterion for an animal model of alcoholism and may be an important component of the genetic predisposition to alcoholism. The aim of this study was to determine whether the selectively bred Warsaw High Preferring (WHP) line of alcohol-preferring rats would develop behavioral and metabolic tolerance during the free...

We read with great interest the article entitled “Effectiveness of single-session ultrasound-guided percutaneous ethanol sclerotherapy in simple breast cysts” by Ozgen (1), which has been recently published in Diagnostic and Interventional Radiology. However, we would like to address some limitations. First, simple breast cysts do not need any follow-up, as they do not show malignant transforma...

The effect of different contextual stimuli on different ethanol-induced internal states was investigated during the time course of both the hypothermic effect of the drug and of drug tolerance. Minimitters were surgically implanted in 16 Wistar rats to assess changes in their body temperature under the effect of ethanol. Rat groups were submitted to ethanol or saline trials every other day. The...

A flow injection method was developed for the sequential enzymatic determination of ethanol and glycerol in wines, using immobilised ethanol dehydrogenase and glycerol dehydrogenase, respectively. The enzymes were immobilised separately on alkylaminated controlled pore glass. A multi-site spectrophotometric detection system was used in parallel configuration to monitor the absorbance change in ...

We evaluated the efficacy of percutaneous ethanol injection therapy (PEIT) as a therapeutic option for recurrence of secondary hyperparathyroidism after subtotal parathyroidectomy in ESRD patients. Six patients underwent PEIT. A mean of 1.3 ± 0.8 ethanol injections was performed. Nodular volume was 1.5 ± 1.7 cm(3), and 2.8 ± 2.8 cm(3) of ethanol was injected per patient. After ethanol injection...

Objective: The objective was to simply and effectively treat oral haemangiomas without complications using ethanol injection. Methods: As much blood as possible was aspirated from a haemangioma, and then absolute ethanol was injected into the cavity. For especially large haemangiomas, we repeated the treatment. Results: Good results were obtained without complications, no enlargement or recurre...
