CONCLUSION<br />

The results presented <strong>in</strong> this study <strong>in</strong>dicate that the<br />

HCC <strong>in</strong>duced by N-nitrosodiethylam<strong>in</strong>e was<br />

effectively <strong>in</strong>hibited by the treatment with MEWF at<br />

a dose <strong>of</strong> 200 mg/kg, b.w. When compared to<br />

standard drug silymar<strong>in</strong> treated group, the MEWF<br />

treated group showed better efficacy towards NDEA<br />

<strong>in</strong>duced hepatocellular carc<strong>in</strong>oma. In rats treated with<br />

MEWF alone no significant change was observed.<br />

The pretreatment with MEWF on pathological<br />

conditions <strong>in</strong> chronic hepatic disorder such as HCC<br />

showed remarkable protection; provide a new<br />

approach to study the active pr<strong>in</strong>ciple responsible for<br />

chemoprevention <strong>in</strong> tumor models. However further<br />

work is required for the fractionation <strong>of</strong> MEWF and<br />

identification <strong>of</strong> the active compound which is<br />

underway.<br />

Conflict <strong>of</strong> <strong>in</strong>terest statement<br />

We declare that we have no conflict <strong>of</strong> <strong>in</strong>terest.<br />
