A. Dead animals will smell until they are completely decomposed or until they are dried out, whichever comes first. It goes without saying that the larger the animal, the more biomass there is to rot, the stronger the smell will be, and the longer the smell will last.
When cells are damaged by disease or injury, large amounts of these leak out, causing blood tests to show that enzymes are elevated above normal. (You can roughly compare this situation to a car that's leaking oil. Leaks in many parts of the engine can have the same result: oil all over your driveway.)
An elevated CPK result, or one that goes up from the first test to the second one or later samples, usually indicates there has been some recent muscle damage.... Creatine phosphokinase or, 'CPK,' is an enzyme found in high concentrations in a person's muscles where it facilitates a person's muscle contraction.PK is also referred to as, 'creatine kinase,' or, 'CK.' A doctor might check a person's CPK when they are concerned a person has experienced muscle damage or breakdown. In a rare condition called, 'rhabdomyolysis,' extreme muscle breakdown floods a person's blood with CPK and additional chemicals in their muscle cells.
