Ethane evolution: a new index of lipid peroxidation
Science (New York, N.Y.)
|January 18, 1974
Summary
Ethane production indicates lipid peroxidation in mouse liver and brain tissues. This process, measured by ethane evolution, can be monitored in both tissue homogenates and live animals.
Area of Science:
- Biochemistry
- Toxicology
- Animal Models
Background:
- Lipid peroxidation is a significant process in cellular damage.
- Identifying reliable biomarkers for lipid peroxidation is crucial for research.
Purpose of the Study:
- To investigate ethane evolution as a marker for lipid peroxidation.
- To assess the role of alpha-tocopherol and carbon tetrachloride in ethane production.
Main Methods:
- Incubation of mouse liver and brain homogenates at 37°C.
- Administration of carbon tetrachloride and phenobarbital to mice.
- Measurement of ethane evolution in vitro and in vivo.
- Assessment of alpha-tocopherol's inhibitory effect.
Main Results:
- Spontaneous ethane formation observed in mouse liver and brain homogenates.
- Ethane evolution was inhibited by alpha-tocopherol.
- Carbon tetrachloride injection induced ethane production in mice.
- Phenobarbital stimulated ethane release, while alpha-tocopherol reduced it.
Conclusions:
- Ethane production serves as a valid indicator of lipid peroxidation.
- This method is applicable to both tissue homogenates and intact animal models.
- Findings support the use of ethane evolution as a biomarker in toxicological studies.
