Background: It has been reported that Moringa oleifera (MO) has different medicinal properties. The aim of this study was to evaluate the hepatoprotective role of Moringa oleifera extract on acetaminophen-induced liver fibrosis in albino rats on a biochemical and histological basis. Forty male albino rats were divided into four groups: group I (control group), healthy rates; group II (acetaminophen group), rates received acetaminophen for induction of liver fibrosis; group III (treated group), liver fibrosis of rates treated with Moringa oleifera extract; and group IV (prophylactic group), rates treated with Moringa oleifera extract before and after induction of liver fibrosis. Serum liver function parameters were quantified using a spectrophotometer, while tumor necrosis factor α (TNF-α) and transformed growth factor beta (TGF- β) in liver tissue homogenate by means of enzyme-linked immunosorbent assay (ELISA), and expression of liver tissue TNF-α and TGF-genes was measured by real-time PCR after extraction and purification. Hepatic tissue was also evaluated under a microscope for histopathological changes. Results: Our results showed a significant decrease in liver enzymes, TNF-α, and TGF-β in the treated and prophylactic groups compared to the acetaminophen group, and our biochemical data were consistent with the histopathological findings confirming the hepatoprotective effect of Moringa oleifera extract. Conclusions: Biochemical parameters and histopathology results provide evidence that Moringa oleifera ethanolic extract has a great potential to prevent and improve liver damage due to its protective activity. © 2020, The Author(s).
