    Abstract:
    The chemopreventive activity of methanolic extract of Apium graveolens seeds (celery seeds) has been investigated against Solt Farber protocol of hepatocarcinogenesis, oxidative stress and induction of positive foci of gamma-GT in the liver of Wistar rats. The prophylactic treatment of celery seeds extract protected dose dependently against diethylnitrosoamine (DEN)+2-acetylaminofluorine (AAF)+partial hepatectomy (PH) induced hepatocarcinogenesis and other related events such as induction of gamma-GT positive foci (P<0.001). 2-AAF administration in diet with PH in rats resulted in increased hepatic ornithine decarboxylase (ODC) activity and a consequent increase in the rate of DNA synthesis when compared to saline treated control group while pretreatment of rats with celery seeds extract resulted in inhibition of aforementioned parameters dose dependently. The augmentation of quinone reductase (QR), glutathione-S-transferase (GST) and serum gamma-glutamyl transpeptidase (GGT) activities; and depletion of the tissue GSH content after 2-AAF (i.p. injection) for five consecutive days was prevented with the administration of celery seed extract. On the basis of the above results it can be said that A. graveolens is a potent plant against experimentally induced hepatocarcinogenesis in Wistar rats.
