Figure 1From: Macrolide antibiotics like azithromycin increase lipopolysaccharide-induced IL-8 production by human gingival fibroblasts The effect of macrolide antibiotics on HGFs proliferation. HGFs were plated in 96-well microplate at 2,000 cells/well and were added the media containing macrolide antibiotics (0, 0.1, 1 and 10 μg/ml). MTT assay was performed at day 0, 3 and 7 days. **P < 0.01 (Dunnett method).Back to article page
