INTRODUCTION Many cases of hydrocarbon toxicity occur annually due to oral or inhalational exposure. Rarely are hydrocarbons injected subcutaneously or intravenously. These parenteral routes of exposure, however, can have a wide range of consequences ranging from mild skin irritation to tissue necrosis, pulmonary injury, neurologic consequences, cardiovascular collapse, and death. WD-40TM is a ...
Acute exposure of sensitized mice to antigen elicits allergic airway disease (AAD) characterized by Th2 cytokine-dependent pulmonary eosinophilia, methacholine hyperresponsiveness and antigen-specific IgE elevation. However, chronic exposure induces a local inhalational tolerance (LIT), with resolution of the airway responses but persistent systemic IgE production. To further determine if syste...
Coxiella burnetii is the etiological agent of Q fever, a disease that is often spread to humans via inhalational exposure to the bacteria from contaminated agricultural sources. Outbreaks have been observed all over the world with larger foci generating interest in vaccination programs, most notably in Australia and the Netherlands. Importantly, exposure rates among military personnel deployed ...
Seeds of the castor bean plant Ricinuscommunis L (CB) contain ricin toxin (RT), one of the most poisonous naturally-occurring substances known. Ricin toxin, a water-soluble glycoprotein that does not partition into the oil extract, is a ribosome-inactivating toxin composed of two chains, labeled A and B. Severity of the toxicity varies depending on the route of exposure to the toxin. Inhalation...
The role of the cellular protein LRP6 in anthrax toxin entry is controversial. Previous studies showed that LRP6 was important for efficient intoxication of human M2182 prostate carcinoma cells but other studies performed with cells from gene-knockout mice demonstrated no role for either LRP6 or the related LRP5 protein in anthrax toxin entry. One possible explanation for this discrepancy is th...
Here we present data on liver metal levels and expression of genes related to iron homeostasis in rhesus monkeys after inhalational manganese exposure. Archived liver samples from rhesus monkeys exposed to 0 (n=6), 0.06 (n=6), 0.3 (n=4) and 1.5 (n=4) mg/m(3) manganese inhalation for 65 days were obtained from a published study ("Tissue manganese concentrations in young male rhesus monkeys follo...
On October 4, 2001, we confirmed the first bioterrorism-related anthrax case identified in the United States in a resident of Palm Beach County, Florida. Epidemiologic investigation indicated that exposure occurred at the workplace through intentionally contaminated mail. One additional case of inhalational anthrax was identified from the index patient's workplace. Among 1,076 nasal cultures pe...
patients referred to amir-alam hospital, affiliated to tehran university of medical sciences, were given anesthesia through two ways inhalationally (by means of sodium thiopenton) and intravenously (halothane+n2o). in this article, we discuss the results obtained from the patients' bronchoscopies. according to our study, inhalational anesthesia have had desirable effects since halothane ha...
