Summary
Early exposure to ethanol retards growth and alters hepatic metabolism in Wistar rats. Both maternal and offspring ethanol consumption significantly impacted growth and liver function, highlighting strain and sex importance.
Area of Science:
- Toxicology
- Metabolic Science
- Animal Models
Background:
- Ethanol consumption during development can impact growth and organ function.
- Understanding the effects of early-life ethanol exposure on hepatic metabolism is crucial.
Purpose of the Study:
- To investigate the impact of early-life and post-weaning ethanol exposure on growth and hepatic metabolism in Wistar rats.
- To determine the influence of ethanol exposure timing on growth retardation and liver triglyceride and glycogen content.
Main Methods:
- Wistar-derived OETI strain rats were divided into groups based on ethanol (15% aqueous solution) exposure timing.
- Group A: Dams received ethanol from delivery to weaning; offspring received ethanol from weaning.
- Group B: Rats received ethanol only after weaning. Control groups were maintained.
Main Results:
- Group A exhibited the most significant growth retardation. Group B also showed decreased growth compared to controls.
- Hepatic glycogen content was reduced in all ethanol-treated groups.
- Increased liver triglyceride content was observed in female rats of Group A.
Conclusions:
- Early-life ethanol exposure, starting from dams and continuing in offspring, severely impacts growth and hepatic metabolism.
- The timing of ethanol exposure and the sex of the animal are critical factors in hepatic metabolic responses.
- Strain and sex are important considerations for studying ethanol's effects on hepatic metabolism.
