Objectives: The objective of the research was to investigate and assess how effective Vitamin E is in preventing or reducing liver inflammation and stromal congestion associated with alcoholic liver injury.
Study design: This is a laboratory-based experimental study.
Methodology: A total of 18 domestic rabbits were divided into groups A, B, and C. Group A was the control group and treated with normal saline as a placebo. Groups B and C were given 30% ethanol in a daily dose of 30 ml/kg/day. Additionally, group C was treated with vitamin E at 50 mg/kg/day. All three groups were sub-divided into two sub-groups I and II on the basis of experimental duration of eight weeks and four weeks respectively. The subgroups with eight weeks of experimental time duration were categorized as "category E8" and subgroups with an experimental duration of four weeks were categorized as "category E4". Liver tissue samples from each animal were subjected to staining using hematoxylin and eosin (H&E) stain for histological staining in order to assess portal inflammation and to measure the sizes of hepatic sinusoids and central veins to evaluate hepatic congestion.
Results: A statistically significant variance was observed in the size of central veins, hepatic sinusoids, and invasion of inflammatory cells in portal areas across and between the groups within categories E4 and E8. Animals treated with vitamin E exhibited lower invasion of inflammatory cells and larger central veins and sinusoids compared to those not treated with vitamin E.
Conclusion: Vitamin E may have a significant role in reducing or limiting the infiltration of inflammatory cells and could help prevent hepatic congestion in cases of alcoholic liver injury.
