Physiological conditions in humans affect plasma amino acid profiles that might have potential for medical use. Because the branched-chain amino acids (BCAAs) leucine, isoleucine and valine are used as medicines and supplements, we investigated the acute effects of individual BCAAs (10-90 mg/kg body weight) or mixed BCAAs ingested as a bolus on plasma amino acid profiles in young healthy men. P...

Tiagabine is an anticonvulsant acting by selective inhibition of neuronal and glial gamma-aminobutyric acid uptake, resulting in increased gamma-aminobutyric acid-mediated inhibition in the brain. Few reports in the literature describe the clinical course of severe tiagabine intoxication. A 44-year-old woman presented after deliberate self-poisoning with 100 tiagabine 15 mg tablets (1,500 mg; 2...

A common belief is that alkali ingestion causes severe esophageal damage and limited gastric injury due to the buffering action of acid. Gastric injury has been observed in patients who ingested alkali. Gastric outlet obstruction (GOO) secondary to caustic ingestion occurs due to fibrosis after resolution of the acute injury and inflammation, most commonly 6 to 12 weeks after initial ingestion....

BACKGROUND Self-poisoning usually occurs by the ingestion of a single lethal compound and majority of the poisoning cases in our country are due to the pesticides. Suicide by ingestion of more than one poisonous substance is rare except alcohol and multiple drugs. To the best of our knowledge, suicidal ingestion of a mixture of rodenticide and battery acid has not been reported before in medica...

Consumption by animals and humans of earthy materials such as clay is often related to gut pathologies. Our aim was to determine the impact of kaolinite ingestion on glucose and NEFA transport through the intestinal mucosa. The expression of hexose transporters (Na/glucose co-transporter 1 (SGLT1), GLUT2, GLUT5) and of proteins involved in NEFA absorption (fatty acid transporter/cluster of diff...

We have previously shown that whey protein hydrolysate (WPH) causes a greater increase in muscle protein synthesis than does a mixture of amino acids that is identical in amino acid composition. The present study was conducted to investigate the effect of WPH on gene expression. Male Sprague-Dawley rats subjected to a 2 h swimming exercise were administered either a carbohydrate-amino acid diet...

Ingestion of caustic substances, either acidic or alkali, is a well-known cause significant mortality and morbidity in the pediatric adult populations. According to pH, physical form, amount, rate ingestion these wide range immediate as well possible subsequent chronic complications can result. Some patients may have minimal mild symptoms. However, others present with moderate even serious symp...

There have been reports of a 24-48-hr delay in the recovery of platelet cyclooxygenase activity and platelet function after the ingestion of aspirin. However, these studies employed a single aggregating agent to stimulate enzymatic or functional activity. We investigated the effects of some pairs of aggregating agents on 14 platelet-rich plasmas (PRP) from normal subjects 2 and 4 hr after inges...

A retrospective analysis of 98 patients, less than 15 years of age, treated for caustic ingestion during 1976-1990 was performed to evaluate the modern consequences of caustic ingestion in children and to set indications for esophagoscopies and radiographic and laboratory examinations. Dishwasher detergents were ingested by 56 children. There were no lye ingestions, since lye has not been freel...

A study of the plants, and their associated poisons, in Poison Garden at The Alnwick was undertaken across a calendar year. By selecting 25 plants Garden, we have been able to develop single chromatographic method for determination quantification 15 plant toxins by liquid chromatography mass spectrometry (LC-MS). Chromatographic separation achieved on C18 column (3.5 µm, 100 × 4.6 mm) with grad...
