Aim of this study was to evaluate the biotransformation of simple phenols after ingestion of edible fruits and mixed food. It was analyzed hippuric acid in urine as biomarker of conjugation in the liver cells of glycine with aromatic phenolic acids such benzoic and salicylic acid from ingested food. Measurement of hippuric acid in urine samples of 10 healthy individuals: 5 female and 5 male wit...

Previous studies have demonstrated that fatty acid oxidation in the liver may affect food intake. This study examined the influence of preloading of medium-chain triacylglycerol (MCT) on food intake in comparison with long-chain triacylglycerol (LCT). Male rats were fasted for 18 h and then administered LCT or MCT emulsion orally. Each group of rats was allowed to rest for 30 min, and then food...

ingestion can cause severe injury to the esophagus and stomach. The severity and extent of esophageal and gastric damage resulting from caustic ingestion depend upon several factors. In the present report, we describe the case of a 55-year-old schizophrenic man who drank 400 mL of hydrochloric acid. Endoscopy indicated the presence of white esophageal mucosa and black gastric mucosa, which is e...

Although most investigators ( 1 to 4) have agreed that the ingestion of protein increases the output of uric acid in man, there has been no clear elucidation of the mechanism whereby this is accomplished. Mares (5) believed that the increased uric acid in urine following high protein feeding resulted from the deterioration of nuclei of digestive cells concerned in the assimilation of the ingest...

This study examined the effect of a single sodium pyruvate ingestion on a blood acid-base status and exercise metabolism markers. Nine active, but non-specifically trained, male subjects participated in the double-blind, placebo-controlled, crossover study. One hour prior to the exercise, subjects ingested either 0.1 g·kg(-1) of body mass of a sodium pyruvate or placebo. The capillary blood sam...

The concentrations of four chemical species of arsenic in urine were observed with time, after ingestion of three different chemical species of arsenic. The arsenic-rich substances ingested, including arsenite-rich wine, arsenate-rich drinking water, and crab meat which contained organo-arsenic compounds. After ingestion of arsenite-rich wine, approximately 10% of the arsenic was excreted as ar...

INTRODUCTION Acetylic salicylic acid (aspirin) intolerance relates to altered generation and metabolism of arachidonic acid and eicosanoids, and prostaglandins and leukotrienes ingestion of salicylates or COX-inhibitors. METHODS Selective review of literature in PubMed and the Cochrane Library. RESULTS Rhinitis, asthma and nasal polyposis are typical presentations, but urticaria and gut inf...

A prospective clinical study was conducted to evaluate whether or not any biochemical predictor of caustic ingestion and complicating esophageal injury exists. Children who were admitted to the hospital within 24 hours following caustic substance ingestion between 1994 and 2000 inclusive were evaluated. The ingested substance and complaints upon admission were noted. Groups were constructed acc...

conclusions these findings indicate that rehydration with honey drink improves running performance and glucose metabolism compared to plain water in the heat. thus, honey drink can be recommended for rehydration purpose for athletes who compete in the heat. results running distance in run-2 covered by the subjects in the honey drink hd trial (3420 ± 350 m) was significantly (p < 0.01) longer co...

It has been generally accepted that the ingestion of high protein diets leads to an increased excretion of endogenous uric acid. In his review on purine metabolism, Rose (1) has summarized the important contributions on this phase of the subject and has also discussed the various theories which have been formulated to explain the observed phenomena. Lewis, Dunn, and Doisy (2) have made a carefu...
