Abstract:
The purpose of the study is to investigate the distribution of morphine in rats by immunohistochemistry (PAP). The results showed that the content of morphine in CNS was of little change, and the content of morphine in other tissue decresed with prolonged time. Morhine in intraperitioneal fatty tissue showed a great increase after death. The study demonstrated that postmorten distrabution of morphine in rats had significant changes at different time after death. It may provide a reason for better choices of postmortem tissue in detecting addicts of morphine after death.
Insights
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.
