MRI vs. MRA. An MRA, or magnetic resonance angiogram, is a type of MRI scan that uses MRI's magnetic fields and radio waves to produce pictures of blood vessels inside the body, allowing doctors to locate problems that may cause reduced blood flow.
Best Answer: Ethyl alcohol, at the concentrations used in most antibacterial preparations, kills bacteria by disrupting membranes and by denaturing proteins. Ethylalcohol is miscible in water (that is, completely soluble). But ethyl alcohol can also dissolve in the membranes of cells.
Background. Although any alcohol can be toxic if ingested in large enough quantities, the term toxic alcohol has traditionally referred to isopropanol, methanol, and ethylene glycol. Prompt recognition and treatment of patients intoxicated with these substances can reduce the morbidity and mortality associated with these alcohols.
