Pathway illustrating metabolite changes in the liver after naphthalene treatments.

<p>Simplified pathway illustrating metabolite changes in the liver after different naphthalene treatments. A ↑ and ↓ at first and second position indicates changes (<i>p</i> <0.05 by Scheffé’s method) in the single challenge dose and repeated naphthalene treatment groups, respectively, relative to the control. The ratio of the repeated treatment group and the single dose challenged group is given at the last position. “–”indicates insignificant changes in the metabolites.
