ABSTRACT:
Walnuts and peanuts contain phytochemicals that exhibit properties that
may prevent colon cancer development. The objective was to determine the
potential of walnuts and peanuts on Azoxymethane (AOM) induced Aberrant Crypt
Foci (ACF) and the activity of detoxification enzymes: Glutathione S-Transferase
(GST), Catalase (CAT), and Superoxide Dismutase (SOD) in Fisher 344 male rats. After
1 week acclimatization period, 20 rats were randomly divided into 5 groups. One
was fed AIN93G Control (C) diet, 4 groups were fed walnuts (W) and peanuts (P)
at 5% and 10%. At 7 - 8 weeks, rats received AOM injections at 16 mg/kg body
weight (subcutaneously). Rats were killed by CO2 asphyxiation at 17
weeks. Enzyme activities GST, CAT and SOD were determined. ACF incidence in
rats fed W (5% and 10%) was 131 and 95, and in those fed P (5% and 10%) was 110
and 56. Rats fed W and P had a significant (p p
