Effects of frying oil and Houttuynia cordata thunb on xenobiotic-metabolizing enzyme system of rodents

Table 4 Activity of aniline hydroxylase (ANH) and aminopyrine demethylase (AMD) from the liver of Sprague-Dawley rats fed with the fresh/oxidized frying oil and 0%, 2% and 5% H· cordata thunb powder diets for 4 wk (mean±SD, n = 8).

¹Mean values significantly differ between the two oil groups (P<0.05). ^2,3Means not sharing common superscript letters significantly differ from one another by Duncan’s multiple range test for the same oil group (P<0.05). ⁴Analyzed by a two-way ANOVA.

⁵NS: No significance.
