Post-mortem hypoxanthine levels in the vitreous humour. An introductory report
Forensic Science
|July 1, 1978
Summary
Post-mortem hypoxanthine levels in vitreous humor can indicate tissue hypoxia. Elevated levels were found in drug intoxication cases, suggesting prolonged hypoxia from respiratory depression.
Area of Science:
- Forensic Toxicology
- Biochemistry
Background:
- Hypoxanthine levels in biological fluids indicate tissue hypoxia.
- Vitreous humor is a valuable post-mortem biological sample.
Purpose of the Study:
- To investigate post-mortem hypoxanthine levels in vitreous humor.
- To correlate these levels with cause of death and time post-mortem.
Main Methods:
- Analysis of vitreous humor hypoxanthine in 86 legal autopsy cases.
- Comparison of hypoxanthine levels across different causes of death.
Main Results:
- Mean hypoxanthine levels were significantly higher than in vivo plasma levels.
- Elevated levels were observed in trauma and myocardial infarction cases.
- Statistically significant elevation was found in drug intoxication cases, but not in strangulation or suspension cases.
- Hypoxanthine levels were independent of time post-mortem up to 48 hours.
Conclusions:
- Post-mortem vitreous humor hypoxanthine levels can reflect tissue hypoxia.
- Elevated hypoxanthine in drug intoxication suggests drug-induced prolonged tissue hypoxia due to respiratory depression.
