Microscopic postmortem changes in kidneys of the domestic fowl.

Eighty-four male white leghorn chickens were killed by CO2 gas to determine the type, rate, and sequence of postmortem microscopic changes in the kidneys of dry and wet intact carcasses. They were held at 29 or 18 C with 50% relative humidity for different times postmortem. Microscopic postmortem changes in the different segments of the nephron underwent a different rate and sequence of cellular changes.

Microscopic postmortem changes in adrenal glands of the domestic fowl.

Eighty-four male white leghorn chickens were killed by CO2 gas to determine the type, rate, and sequence of microscopic postmortem changes in the adrenal glands of dry and wet intact carcasses. They were held at 29 or 18 C with 50% relative humidity for different times postmortem. The sequence of microscopic postmortem changes was similar in all chickens except at 18 C, when karyorrhexis of cortical and medullary cells was observed.

Determining time of death of a dog by analyzing blood, cerebrospinal fluid, and vitreous humor collected at postmortem.

Blood, cerebrospinal fluid, and vitreous humor collected at antemortem and postmortem from 60 dogs were analyzed to determine what chemical value may be used for estimating time of death. Euthanatized dogs were maintained at 4 C, 20 C, or 37 C for 3, 6, 12, 24, or 48 hours. At postmortem, vitreous humor potassium values increased with increased time and increased temperature.
