BACKGROUND
Trichosanthes lobata (family cucurbitaceae) is used to treat malarial fever and liver disorders. This study aims to investigate possible hepatoprotective activities of ethanolic extract of Trichosanthes lobata against paracetamol-induced hepatotoxicity.
METHODS
Hepatotoxicity was induced in Wistar male rats by oral administration, 2 g/kg body weight on 7th day after the administration of ethanolic extract of Trichosanthes lobata and silymarin (100 mg/kg). Ethanolic extract of Trichosanthes lobata was administered orally at doses of 200 mg/kg and 400 mg/kg body weight daily for 7 days. Several serum markers, aspartate transaminase, alanine transaminase, alkaline phosphatase, bilirubin, total protein was measured to assess the effect of the extract on paracetamol (acetaminophen)-induced hepatic damage. The study included histopathological examination of liver sections.
RESULTS
Blood samples from rats treated with ethanolic extract of Trichosanthes lobata (200 mg/kg body weight and 400 mg/kg body weight) had significant reductions in serum markers in paracetamol administered animals, indicating the effect of the extract in restoring the normal functional ability of hepatocytes. Silymarin (100 mg/kg, p.o.) was used as a reference drug.
CONCLUSIONS
The ethanolic extract of Trichosanthes lobata exhibits protective effects against paracetamol‒induced hepatotoxicity.
