From: Intragingival injection of Porphyromonas gingivalis-derived lipopolysaccharide induces a transient increase in gingival tumour necrosis factor-α, but not interleukin-6, in anaesthetised rats

Figure 2

Effects of intragingival injection of Pg ‐LPS or Ec ‐LPS on the gingival levels of IL‐6. All values are presented as a percentage of the baseline level of IL‐6, which was the mean of the IL‐6 level in the two samples measured immediately prior to LPS treatment. The data are expressed as the mean change in the 1‐hr observation period (ordinate) after intragingival injection of LPS (abscissa). Vertical bars indicate SEM. The basal gingival IL-6 level is control (100%). Neither injection of Pg‐LPS nor Ec‐LPS into the gingiva‐altered gingival levels of IL‐6 (n=6–7). Ec‐LPS, lipopolysaccharide derived from Escherichia coli; IL, interleukin; LPS, lipopolysaccharide; Pg‐LPS, lipopolysaccharide derived from Porphyromonas gingivalis; SEM, standard error of the mean.
