There is considerable interest in the potential health effects resulting from inhalation of acidic aerosols. However, except for well documented irritant effects and acid-induced changes in lung clearance function, other potential health effects have not been well defined. This study was designed to
This is a report of a case in which a significant quantity of sulfuric acid was ingested, causing life threatening respiratory distress, secondary to glottic injury and edema, and cardiovascular collapse. Vigorous resuscitive efforts allowed survival through the first 48 hours and two major
Arabidopsis leaves treated with simulated acid rain (SiAR) showed phenotypes similar to necrotic lesions caused by biotic stresses like Pseudomonad infiltration. Exposure of Arabidopsis to SiAR resulted in the up-regulation of genes known to be induced by the salicylic acid (SA)-mediated pathogen
Deliberate ingestion of a corrosive acid is an unusual manner of death. Sulfuric acid, often used in electrical industry, chemical laboratories, and agriculture, is fatal at a dosage of 3.5-7.0 ml. The mortality rate is quite high, with only 35% recovery rate. Poisoning by sulfuric acid resembles
The authors present a case of pyloric and duodenal obstruction in an 8-year-old child, resulting from accidental ingestion of sulfuric acid. A marked pyloric and duodenal cicatrizing stenosis resulting from ingestion of sulfuric acid is seen infrequently, especially in pediatric age. Sulfuric acid
Exposure to strong acids such as sulfuric acid to either the skin or the gastrointestinal or respiratory mucosa will result respectively in significant-occasionally fatal-cutaneous chemical burns as well as devastating corrosive damage to the respiratory and gastrointestinal tracts. Most injuries
Sulfuric acid is easy to obtain and leads to severe caustic burn. Caustic burns are increasingly common in homicides and suicide. We reported a case of sulfuric acid burn due to a family criminal act. Immediate skin washout was performed and avoided many complications like eyes lesion or their
Acidic sulfate is the most toxicologically important sulfur oxide which exists in the ambient air. To determine if particle size influences toxic effects of sulfuric acid, we investigated the effects of sulfuric acid aerosols of two different sizes on biochemical and cellular parameters of
Caustic ingestion is a common cause of life-threatening upper gastrointestinal tract injuries. It mostly happens in children as accidental exposure, but may occur in adults as a result of suicide attempt. We present a case of an acute abdomen that occurred after a peculiar way of self-administration
Studies examining effects of air pollutants often use single compounds, while "real world" exposures are to more than one chemical. Thus, it is necessary to assess responses following inhalation of chemical mixtures. Rabbits were exposed for 3 hr to sulfuric acid aerosol at 0, 50, 75, or 125
The aim of the present study was to examine the role of endogenous peroxisome proliferator-activated receptor-alpha (PPAR-alpha) ligand on the permeability and structure of small intestine tight junctions (TJs) in an animal model of experimental colitis, induced by dinitrobenzene sulfuric acid
BACKGROUND
Acids account for 20% of all chemical exposures through various routes. Caustic acids such as hydrochloric and sulfuric acid are common ingredients in many household and industrial products. Due to the corrosive properties of these substances, tissue injury caused by oral exposure can
OBJECTIVE
A study was made of the effects of low-level laser irradiation on the cicatrization of superficial wounds in the pharyngeal mucosa of the horse.
METHODS
Duplicate pharyngeal mucosal ulcers were induced in 12 Spanish horses with submucosal injection of sulfuric acid. A fibroendoscope and an
Very-long-chain acyl-CoA dehydrogenase (VLCAD) catalyzes the first reaction in the mitochondrial fatty acid β-oxidation pathway. VLCAD deficiency is associated with the accumulation of fat in multiple organs and tissues, which results in specific clinical features including cardiomyopathy,
The case of a patient with acid burns of the large bowel from a self-administered enema of 95 percent sulfuric acid solution is reported. The authors were unable to find a similar case in the English medical literature. The patient presented in metabolic acidosis, and flexible sigmoidoscopy was of
