Hepatic encephalopathy (HE) is a syndrome resulting from acute or chronic liver failure. This study was designed to evaluate the effect of rutin on thioacetamide (TAA) orγ-radiation-induced HE model. Animals were received with TAA (200mg/kg, i.p.) twice weekly for four weeks or exposed to 6Gy of γ-radiation to induce HE then groups orally treated with rutin (50mg/kg b.wt.) for four weeks. At the end of experiment, blood, liver and brain samples were collected to assess biochemical and biophysical markers as well histopathological investigations. TAA or γ-radiation exposed rats experienced increases in serum activities of ALT, AST, ALP and ammonia level. Also an alteration in relative permeability and conductivity of erythrocytes was observed. Furthermore, cytokines levels and AChE activity were induced whereas the activities of HO-1 and neurotransmitters contents were depleted. TAA or γ-radiation caused distortion of hepatic and brain architecture as shown by histopathological examination. Treatment with rutin resulted in improvement in liver function by the decline in serum AST and ALT activities and reduction in serum ammonia level. In addition, the administration of rutin significantly modulated the alteration in cytokines levels and neurotransmitters content. Histopathological examinations of liver and brain tissues showed that administration of rutin has attenuate TAA or radiation-induced damage and improve tissue architecture. Consequently, rutin has been a powerful hepatoprotective effect to combat hepatic encephalopathy associated hyperammonemia and its consequential damage in liver and brain.
