Effect of muraglitazar on carrageenan-induced production of inflammatory mediators in the mouse. Muraglitazar was administrated to animals intraperitoneally two hours prior to carrageenan injection (1.5%). (a) Paw oedema was measured before and six hours after carrageenan injection by plethysmometer. Oedema is expressed as difference between carrageenan-treated paw and control paw. (b-d) Six hours after carrageenan injection, the animals were sacrificed and total RNA was extracted from subcutaneous connective tissue of carrageenan-injected and control paw. IL-6, TNF╬▒ and inducible nitric oxide synthase (iNOS) mRNA were determined by RT-PCR. The results were normalized against glyceraldehyde-3-phosphate dehydrogenase (GAPDH) mRNA and mRNA levels in carrageenan-treated paw were compared to those in control paw. Values are mean + SEM (n = 5 to 7). *P <0.05 and **P <0.01 as compared to mice treated with carrageenan alone.
