Effect of systemic treatment with Asp or Clop on the gingival contents of CCL5 (panel A), CXCL4 (panel B), CXCL12 (panel C) in rats with ligature induced periodontal disease when stimulus is removed. Results were normalized to the total protein contents in each sample and expressed as pg/mg of protein. Values are expressed as mean±SD. * P<0.0001 vs Repair (Rep)+ NaCl, Rep+ Asp, Rep+ Clop; **P<0.001 vs Clop; #P<0.0001 vs Rep+ Asp, Rep+ Clop; ##P<0.001 vs Rep+ Asp and Rep+ Clop.
