Abstract:
Synthetic drugs are associated with adverse side-effects and rapid increase in resistance to most of them
inspires to evaluate plants for their therapeutic values. We have been aimed to suggest the medicinal use of Nigella sativa seed aqueous extract to minimize the severity of liver damage via its antioxidant properties and its role in maintenance of cell ion-homeostasis. Annoyances in serum levels of some antioxidants and trace metals in human hepatitis C infected patients were compared with that from acetaminophen-induced hepatotoxic rabbits. Serum analysis of human patients and that of hepatotoxic rabbits have exhibited the same trend of incidence of liver marker enzymes, antioxidant levels, and trace metal concentrations, except for the serum levels of cobalt. Significance of pre-/ or posttreatment of Nigella sativa to acetaminophen induced-hepatotoxic rabbit has also evaluated. NS post-treatment to rabbits has been found effective in normalizing the levels (P<0.001) of serum liver markers; especially the ALP levels, and the antioxidants; with significant effect on the serum catalase levels. However, NS pre-treatment has shown its role (P<0.001) in maintaining the serum nickel and cobalt concentrations. Therefore, we suggest the use of Nigella sativa seeds as pre-/ or post-treatment therapy, and also as supplement to the normal medications of liver infection to normalize the status of cell antioxidants and trace metal concentrations.
