Pathologic changes in a rabbit model of Reye's syndrome
Pediatric Research
|November 1, 1982
Summary
Continuous infusion of sodium octanoate causes liver and kidney damage in rabbits. These findings in animal models mimic the pathology seen in Reye
Area of Science:
- Biochemistry
- Toxicology
- Pathology
Background:
- Sodium octanoate is a short-chain fatty acid.
- Reye's syndrome is a serious condition affecting the brain and liver.
Purpose of the Study:
- To investigate the effects of continuous sodium octanoate infusion in rabbits.
- To compare rabbit pathology to human Reye's syndrome.
Main Methods:
- Continuous intravenous infusion of sodium octanoate in rabbits.
- Pathologic examination of liver, kidney, heart, lungs, and brain tissues.
- Ultrastructural analysis of cellular changes.
Main Results:
- Microvesicular fatty accumulation observed in rabbit liver, kidney, heart, and lungs after 4 hours.
- Mitochondrial swelling and pleiomorphism in liver cells.
- Swelling of astrocytic foot processes in the brain, indicating potential cerebral edema.
Conclusions:
- Continuous sodium octanoate infusion induces significant pathological changes in rabbits.
- The observed changes resemble the pathology associated with Reye's syndrome in humans.
- Rabbit models may provide insights into Reye's syndrome mechanisms.
