FIG. 2.

Chronic PCB 126 treatment of male rats reduced A, body weight gain and increased B, relative liver weights, C, hepatic protein content, and D, extractable lipid content in liver as percent of wet weight. Rats were treated with every 2 weeks with i.p. injections of corn oil (vehicle) or PCB 126 in corn oil for 3 months; see Table 1 for details regarding the doses. Data are presented as the mean ± standard deviation. Dunnett's multiple testing correction procedure was used to compare PCB 126 treatment with the corn oil control. *p < .05; ***P < .001.
