Picric acid (2,4,6-trinitrophenol) is widely used in industry, by the military, and as a research/clinical chemistry reagent. Characterization of the toxicity of this chemical has been limited. Thus the acute toxicity, distribution, and metabolism of picric acid were investigated using Fischer 344 rats. The LD50 for picric acid following oral dosing of male… (More)
Tetralin, a component of fuels, solvents, and varnishes, is metabolized in male Fischer 344 rats to 1-tetralol, 2-tetralol, 2-hydroxyl-1-tetralone, 4-hydroxyl-1-tetralone, 1,2-tetralindiol, and 1,4-tetralindiol. Rats treated with tetralin demonstrated the classic lesions of hydrocarbon-induced nephropathy.
The cis- and trans-decalin stereoisomers have found many uses as solvents and fuel components. The metabolism of the decalin isomers in male and female Fischer-344 rats and the effects of the decalins on renal damage were evaluated. Only male rats had kidney damage. Metabolism of cis-decalin yielded cis,trans-1-decalol and cis,cis-2-decalol in the urine of… (More)
The compound 2,2,4-trimethylpentane (2,2,4 TMP) is reported to be especially potent in inducing kidney lesions in male rats (1,2). Although the pathology produced by 2,2,4 TMP has been examined (1), there are no reports concerning the metabolism of 2,2,4 TMP by the male rat. The eight principal urinary metabolites of 2,2,4 TMP found in the urine of Fischer… (More)
The metabolism of isopropylcyclohexane and associated renal pathology were evaluated in male Fischer 344 rats exposed by oral gavage. The rats experienced moderate proximal tubular damage similar to that produced by acyclic, branched-chain hydrocarbons. The urinary metabolites of isopropylcyclohexane included cis-4-isopropylcyclohexanol,… (More)
Indan, a component of fuels, solvents, and varnishes, is metabolized in male Fischer 344 rats to 1-indanol, 2-indanol, 5-indanol, 1-indanone, 2-indanone, 2-hydroxy-1-indanone, cis-1,2-indandiol, and trans-1,2-indandiol. The metabolites were identified using the techniques of gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). The rats… (More)
OBJECTIVES We report the efficacy of alteplase (a recombinant tissue plasminogen activator) with heparin or heparin alone in the treatment of acute thrombosis of the portal venous system. METHODS Ten consecutive patients with acute portal venous system thrombosis were studied. Five patients were treated with alteplase and heparin, and the remaining 5… (More)
The urinary metabolites of n-nonane in male Fischer 344 rats, after administering the hydrocarbon by gavage, included gamma-valerolactone, delta-hexanolactone, 2,5-hexanedione, delta-heptanolactone, 1-heptanol, 2-nonanol, 3-nonanol, 4-nonanol, 4-nonanone and 5-methyl-2-(3-oxobutyl)furan. Metabolism strongly favored the formation of monoalcohols and… (More)
A case of obstructive intramural hematoma of the esophagus post variceal sclerotherapy is reported in a 44-year-old man who presented retrosternal pain and complete dysphagia. Endoscopy showed a bluish submucosal mass occupying the esophageal lumen. Diagnosis was confirmed by Computed Tomography. A favorable outcome was observed with symptomatic treatment.
