title: Effect of hydroalcoholic extract of ginger on the liver of epileptic female rats treated with lamotrigine.
abstract: OBJECTIVE
  Lamotrigine is an antiepileptic drug, widely used in the treatment of epilepsy; long-term use of this drug can cause hepatotoxicity. Zingiber officinale Roscoe (ginger) possesses antioxidant properties. In present research, the effect ofhydroalcoholic extract of ginger (HEG) on the liver of lamotrigine-treated epileptic rats was investigated Material and Methods: Forty-eight female Wistar rats were selected and allocated to 8 groups of 6 each. Group 1: Negative controls were treated with normal saline. Group 2: Positive controls were treated with lamotrigine (LTG) (10 mg/kg) daily by gavages for 4 consecutive weeks. Epilepsy was induced in treatment groups by i.p. injection of pentylenetetrazol (PTZ) (40 mg/kg). Group 3: Epileptic group received normal saline (10 ml/kg). Group 4: Epileptic group was treated with LTG (10 mg/kg). Groups 5 and 6: Epileptic groups received HEG (50 and 100 mg/kg). Groups 7 and 8: Epileptic groups received LTG and HEG (50 and 100 mg/kg). At the end of 28 days, blood samples were drawn and their livers were processed for light microscopy.
  
  
  RESULTS
  The mean values of TG, CHOL, AST, and ALT activity significantly rose (p<0.01) in groups 2, 3, and 4, while in rats treated with HEG (groups 5, 6, 7, and 8), the levels of liver enzymes significantly decreased (p<0.05) compared with epileptic group treated with lamotrigine (group 4). Histopathological changes of liver samples were comparable with respective control.
  
  
  CONCLUSIONS
  These results suggest that hydroalcoholic extract of ginger improves liver function in lamotrigine-induced hepatotoxicity.
