Effect of flunixin meglumine on cytokine levels in experimental endotoxemia in mice.
In this study, effect of flunixin meglumine on serum tumour necrosis factor alpha, (TNFalpha) interleukin-1 beta and interleukin-10 levels was investigated in lipopolysaccharide-induced endotoxic mice. Healthy 273 Balb/C mice were used and divided into three equal groups. Group 1 was injected lipopolysaccharide (Escherichia coli 0111:B4, 250 microg/mouse, intraperitoneally), Group 2 was injected flunixin meglumine (2.5 mg/kg, subcutaneously), and Group 3 was injected lipopolysaccharide + flunixin meglumine. After the treatments, at 0., 1., 2., 3., 6., 12., 24th hours and 3., 5., 7., 14., 21., 28th days blood samples were taken from seven mice in each group. Serum TNFalpha, interleukin-1 beta and interleukin-10 levels were measured using commercially available kits by enzyme-linked immunoassay. Flunixin meglumine did not affect the cytokine levels in healthy animals. While lipopolysaccharide increased serum TNFalpha, interleukin-1 beta and interleukin-10 levels, flunixin meglumine inhibited increases at levels of all cytokines. As result, flunixin meglumine showed depressor effect on cytokine levels in endotoxemia and the effect may be a reason for the first chosen member of nonsteroid anti-inflammatory drug in endotoxemia.
