Abstract
Carbon tetrachloride (CCl(4)) is a well-known hepatotoxin. This work aimed to assess the therapeutic anti-inflammatory immune potentials of the seaweeds Padina pavonia and Jania rubens extracts on carbon tetrachloride (CCL(4))-caused liver damage in mice. Our experimentation included two testing regimens: pre-treatment and post-treatment of P. pavonia and J. rubens extracts in CCL(4)/mice. Pre-treatment and post-treatment of P. pavonia and J. rubens extracts in CCL(4)/mice increased WBCs count and lymphocytes relative numbers and reduced the neutrophils and monocytes relative numbers. Pre-treatment and post-treatment of (CCL4)/mice with P. pavonia and J. rubens extracts significantly reduced the release amounts of pro-inflammatory cytokines TNF-α and IL-6 and significantly inhibited the increased CRP level. Furthermore, pre-treatment and post-treatment of CCL(4)/mice with P. pavonia and J. rubens extracts recovered the activities of GSH, and significantly decreased MDA level. CCL4/mice pre-treated and post-treated with P. pavonia and J. rubens extracts decreased alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels. Pre- and post-treatment of CCL(4)/mice with the P. pavonia and J. rubens extracts ameliorated the liver damages caused by CCl(4) and significantly inhibited the necrotic area, indicating hepatic cell death and decreased periportal hepatic degeneration, fibrosis, and inflammation.
