Evaluation of methanolic extract of Phragmites karka on carbon tetrachloride-induced liver fibrosis in rat

Abstract

<p class="Abstract"><em>Phragmites karka</em> has been reported for its anti-inflammatory and analgesic activities. Here, extracts of leaf and rhizome of the plant were individually investigated in CCl₄-induced hepatofibrosis in male Wistar rats by administering CCl₄ intraperitoneally biweekly for 6 weeks.  Afterwards the animals were investigated for liver fibrosis at biochemical, molecular and histological levels, and it showed a profound increase (p&lt;0.001) in elevation of serum levels of transaminases, γ-glutamyl transpeptidase, mRNA expression of α smooth muscle actin, collagen and transforming growth factor beta (TGFβ), and extracellular matrix deposition and perilobular necrosis. Both extracts markedly (p&lt;0.001) decreased the elevated levels of these markers. Histopathological investigations also substantiated the above results by exhibiting a decreased in extracellular matrix deposition in post-treatment animals. In conclusion, both extracts had substantially modified the biochemical and molecular markers of liver fibrosis, in addition to histological improvement in architecture of liver.</p>
