Fig. 2. IL-1 production in PCM (A) and well-nourished (B) rats
treated with 6-OHDA i.c.v. Bars represents mean values +SEM.
The number of animals is indicated inside the bars. * 6-OHDA
group is significantly different from untreated and solvent-injected
animals (P < 0.02, Kruskal-Wallis test) but not different from the
well-nourished untreated group. The PCM untreated group is significantly
different from the untreated well-nourished group (P < 0.02
Mann-Whitney test).
