Background: This study was designed to investigate the hepatoprotective and in vivo antioxidant effects of the ethanol extract of whole fruit of Lagenaria breviflora (LB) in experimental animals.
Methods: Forty nine Wistar albino rats were divided into seven groups of seven. Group I served as the control group; rats in Group II were given i.p. carbon tetrachloride (CCL4) (1.5 mL/kg) alone; Groups III–VI received different concentrations of plant extract (100, 250 and 500 mg/kg) with CCL4 and Group VII received kolaviron (KV) at 200 mg/kg as a reference hepatoprotective agent.
Results: There was a significant (p<0.05) increase in malondialdehyde (MDA) and hydrogen peroxide (H202) generation in the serum of CCL4 treated rats (Group II) while the serum glutathione (GSH) level decreased significantly. Pretreatment with LB extract led to a significant (p<0.05) increase in serum GSH and a significant (p<0.05) reduction in MDA and H2O2generation. The activities of marker enzymes, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), bilirubin, creatinine and blood urea nitrogen (BUN) increased (p<0.05) significantly in CCL4 treated rats (Group II).
Conclusions: The present study suggested that treatment with LB extract enhances the recovery from CCL4 induced hepatic damage and oxidative stress via its antioxidant and hepatoprotective properties.
