Background& Objective: This research is carried out to investigate the Anti-inflammatory activity of the alcoholic extract of flower buds of Crataegus laevigata in experimentally-induced arthritis in rats.
Materials & Methods: the inflammation was i
nduced experimentally by Carrageenan, the standard material that causes non-immune acute inflammation. The size of edema was measured before and after the inducing the inflammation, in control group as well as in group treated by extract and by Diclofenac.
The measurements persist until the 4th hour following the injection of Carrageenan. In another set of experiment, the important biomarker, TNF-α, was calibrated in inflammation-induced groups of rats that received extract or Diclofenac and compared with control.
Results: The extract significantly reduced the size of edema compared with control and this effect was not less than that of Diclofenac, the standard anti-inflammatory drug. Indeed, the extract lowered the values of TNF-α.
Conclusion: The Crataegus laevigata has clear anti-inflammatony effect , but it should be further investigated.
