This paper has been carried out to Study the correlation
between Vitreous Humor Potassium Levels and the Time of
bleeding-caused Death, and to find a formula proposed to calculate
the post mortem interval (PMI) by finding the regression equation.
The present study was prepared to assess the level of
potassium in the vitreous humor fluid, to calculate the post mortem
interval (PMI) by finding the regression equation and to study the
effects of environmental factors like temperature and humidity and
age and sex on it.
The concentration of ethanol in blood and urine provides important evidence in
criminal and civil litigation when alcohol- related crimes are investigated (e.g., drunk driving )Therefore.
Ethanol analysis is the most frequently performed assay in f
orensic toxicology laboratories . .However, the
risk for artifactual formation of ethanol, especially in postmortem specimens, always needs to be
considered . It is often difficult to distinguish between postmortem ethanol production and antemortem
alcohol ingestion .
Ethanol synthesis could be produced by many species of bacteria or yeasts ,which is also influenced as
storage temperature, and the interval between death and autopsy increase .
