Abstract


Background: The aim of this study is to evaluate the potential effect of vitamin C as an antioxidant on liver regeneration after partial hepatectomy and acetaminophen-induced liver injury in Wistar rats.

Methods: A total of 24 male Wistar rats were divided into four groups, each group consisted of 6 rats: group A (control, partial hepatectomy/PHx alone), group B (PHx and vitamin C 250 mg/kg BW), group C (acetaminophen 500 mg/kg BW and PHx), and group D (acetaminophen 500 mg/kg BW with PHx and vitamin C 250 mg/kg BW). Subtoxic dose of acetaminophen was given 24 hours before partial hepatectomy. Vitamin C was given orally via oral gavage for 6 consecutive days after partial hepatectomy. POD 7, all animals were terminated and performed laparotomy to obtain liver tissue for measurement of liver weight and regeneration rate, blood samples for malondialdehyde (MDA) as a lipid peroxidation measurement and histopathological investigation.

Results: The means of regeneration rate in vitamin C groups were significantly higher compared to non-vitamin C group (p<0.05). Similar result, the means of MDA values in vitamin C groups were significantly lower compared to non-vitamin C group (p<0.05). This result suggests a protective effect of vitamin C against lipid peroxidation. Histopathological changes in liver cells were statistically difference between vitamin C groups and non-vitamin C groups (p<0.05).

Conclusions: Our results indicate that vitamin C administration promotes liver regeneration and inhibits lipid peroxidation after partial hepatectomy and acetaminophen-induced liver injury in Wistar rats.
