[The activity of certain enzymes of gluconegenesis in rabbit brain and liver intoxicated by CS2]
Abstract:
The carbon disulphide (CS) administrated chronic to rabbit produced an important inhibition of glucose-6-phosphate phosphohyrolase and fructose-1,6-diphosphate phosphoydrolase activity in brain and liver. The decrease of theses two enzymes of gluconeogenetic cycle seem to justify certain physiological and clinical changes of the neuropsychic and hepatic activity observed in the intoxication by CS2.
Insights
Chronic carbon disulfide (CS2) exposure inhibits key gluconeogenetic enzymes in rabbit brain and liver. This enzyme inhibition explains observed neuropsychic and hepatic dysfunction during CS2 intoxication.
Area of Science:
- Biochemistry
- Toxicology
- Neuroscience
Context:
- Carbon disulfide (CS2) is a toxic industrial solvent.
- Chronic exposure to CS2 can lead to significant health issues.
- Understanding the molecular mechanisms of CS2 toxicity is crucial for developing countermeasures.
Purpose:
- To investigate the impact of chronic carbon disulfide (CS2) administration on specific enzyme activities in rabbits.
- To identify the enzymes affected by CS2 toxicity in the brain and liver.
- To correlate enzyme activity changes with observed physiological and clinical effects.
Summary:
- Chronic administration of carbon disulfide (CS2) to rabbits significantly inhibited glucose-6-phosphate phosphohydrolase and fructose-1,6-diphosphate phosphohydrolase activity.
- These two enzymes are critical components of the gluconeogenetic pathway.
- The reduction in these enzyme activities in the brain and liver was observed following CS2 exposure.
Impact:
- The observed decrease in gluconeogenetic enzyme activity provides a biochemical basis for the neuropsychic and hepatic changes associated with CS2 intoxication.
- This finding aids in understanding the pathophysiology of CS2-induced toxicity.
- Highlights the potential for targeting the gluconeogenetic pathway in managing CS2 poisoning.
