How is the victim of nerve agent exposure presenting with?
How is the victim of nerve agent exposure presenting with convulsions classified? Eyes are the most vulnerable to this agent due to their thin, moist, warm mucosa. Acute Radiation Syndrome results from high-level external exposure to ionizing radiation.
What technique may be used to test for T-2 mycotoxins?
Gas-liquid chromatography (GLC) and high-pressure liquid chromatography (HPLC) with MS may be used to assess the presence of T-2 and related trichothecene mycotoxins in plasma and urine samples . 50-75% of the ingested toxin and metabolites are eliminated in the urine and feces within 24 hours.
What treatment should be given to a patient exposed to T-2 mycotoxins via ingestion?
Your health care provider may administer superactivated charcoal if T-2 mycotoxin is swallowed. Eye exposure should be treated with copious normal saline irrigation.
What cell types are least sensitive to ionizing radiation damage?
The nerve and muscle cells are the slowest to regenerate and are the least sensitive cells. Cells, like the human body, have a tremendous ability to repair damage. As a result, not all radiation effects are irreversible.
What is the first step of self decontamination?
The first step in decontamination is to establish Standard Operating Procedures that minimize contact with waste and thus the potential for contamination.
What device detects and discriminates between nerve and mustard vapors and can be used to sort contaminated and clean personnel during decontamination?
The ICAM detects vapors of chemical agents by sensing molecular ions of specific mobilities (time of flight) and uses timing and microprocessor techniques to reject interferences. The monitor detects and discriminates between vapors of nerve and mustard agents.
What does the T-2 toxin do?
T-2 toxin can affect cellular immune response in animals, and inhibit protein and DNA synthesis. It has been implicated in a variety of animal and human toxicities, such as alimentary toxic aleukia, Msleni joint disease, scabby grain toxicosis, and Kashin-Beck disease.
How do you get exposed to trichothecene?
The trichothecene mycotoxins are a group of toxins produced by multiple genera of fungi. Some of these substances may be present as contaminants from mold or may occur naturally in foodstuffs or in livestock feeds. Symptoms may occur among exposed humans or animals.
What causes ochratoxin A?
Ochratoxin A is produced by several species of Aspergillus and Penicillium and is a common food-contaminating mycotoxin. Contamination of food commodities, such as cereals and cereal products, coffee beans, dry vine fruits, wine and grape juice, spices and liquorice, occurs worldwide.
What is the main effect of ionizing radiation on water?
The radicals formed when ionizing radiation passes through water are among the strongest oxidizing agents that can exist in aqueous solution. At the molecular level, these oxidizing agents destroy biologically active molecules by either removing electrons or removing hydrogen atoms.
How does cyanide cause cell death in the body Jko?
Cyanide poisons the mitochondrial electron transport chain within cells and renders the body unable to derive energy (adenosine triphosphate—ATP) from oxygen. Specifically, it binds to the a3 portion (complex IV) of cytochrome oxidase and prevents cells from using oxygen, causing rapid death.
How are victims going through decontamination prioritized?
How are victims going through decontamination prioritized? Normally, removal of deceased victims from the hot zone will occur: after all viable victims have been removed.
