Figure 1: Impact of a diet containing apocynin on the activity of rat liver NATs.

The NAT activity of the liver S9 fractions (3–8 μg/μl protein) obtained from rats fed a diet free of apocynin (untreated rats) or varying amounts of apocynin (treated rats) was determined ex vivo using pANS and AcCoA, as described in methods. The average value of NAT activity for the untreated group was compared with each NAT activity value for the treated groups, and statistical significance at p < 0.001 is indicated by an asterisk (*). Assays were conducted in triplicate and all values are expressed as mean ± standard deviation values.
