Blood glucose level of control, diabetes and arthritis model rat.
Macroscopic observation on paw swelling of rats. A, Control group rats; B, Model (Adjuvant-induced arthritis) group rats.
Effects of drug-combination on the PGE-2 (A), 20-HETE (B), ET-1 (C) and BNP (D) levels in the experimental groups. Data are the mean ± SD. #P<0.05, ##P<0.01 compare with control group; *P<0.05, **P<0.01 compare with model group.
Effects of drug unification on immunohistochemical. A. Heart tissues. B. Liver tissues. C. Kidney tissues. (1) Control group; (2) diabetes model group; (3) model group of combined disease; (4) rosiglitazone group; (5) rofecoxib group; (6) celecoxib group; (7) treatmented with rosiglitazone and rofecoxib group; (8) treatmented with rosiglitazone and celecoxib group. (Scale bars = 100 um).
Effect of drug combination on the protein of CYP4A1, COX-2 in the experimental groups (A) Kidney. (B) Heart. (C) Liver. Data are the mean ± SD. #P<0.05, ##P<0.01 compare with control group; *P<0.05, **P<0.01 compare with model group.
