From: Effects by periodontitis on pristane-induced arthritis in rats
Effect of pre-existing periodontitis on weight changes, arthritis disease severity and α-1-AGP levels. a Mean changes in weight (grams ± SE) in arthritis rats with and without periodontitis throughout the experimental period of 15 weeks. b Mean arthritis disease severity score (±SE) of front and hind paws in arthritis rats with and without periodontitis, up to 7 weeks after pristane injection. c Mean plasma concentrations (μg/ml ± SE) of α-1-AGP in arthritis rats with and without periodontitis throughout the experimental period of 15 weeks. The results are presented as mean values (±SE) for the groups PA (n = 9) and A (n = 12) at different time-points throughout the experiment. Gray line indicates time point of pristane injection. PIA pristane-induced arthritis, PA rats with experimental periodontitis and PIA, A rats with PIA without periodontitis
