Morphine levels in rat tissues change significantly after death, with notable increases in fatty tissue. This research aids in selecting optimal tissues for detecting morphine use postmortem.

Area of Science:

  • Pharmacology
  • Toxicology
  • Forensic Science

Context:

  • Understanding drug distribution is crucial in forensic investigations.
  • Morphine detection in postmortem samples can indicate drug abuse.

Purpose:

  • To investigate the distribution and changes in morphine levels in rat tissues over time after death.
  • To utilize immunohistochemistry (PAP) for visualizing morphine distribution.

Summary:

  • Morphine levels in the central nervous system (CNS) remained relatively stable postmortem.
  • Morphine concentration decreased in most tissues over time, except for intraperitoneal fatty tissue, which showed a significant increase.
  • These postmortem distribution changes in morphine were time-dependent.

Impact:

  • Provides insights into the postmortem redistribution of morphine.
  • Informs the selection of optimal tissues for postmortem morphine detection in forensic toxicology.
  • Contributes to understanding the challenges in interpreting drug test results from deceased individuals.
