Abstract
The aim of our study is to evaluate anti-inflammatory effect of Chamaemelum nobile. Aqueous extracts were administrated to Wistar rats in bronchial-inflammation experimentally induced by an allergen and ovalbumin, administered intraperitoneally / intranasally (20mg/kg/day). Experimentation showed disturbances in bronchoalveolar fluid with increased leukocyte and lymphocyte levels as well as IL-4 concentration in the lungs and erythrocytes associated with high lipid peroxidation. There were disturbances in enzymatic and non-enzymatic antioxidant defense system. Lungs histopathological showed an inflammatory lymphoplasmacytic infiltrate, moderate edema of alveoli, vascular congestion and suffusion hemorrhage. Administration of aqueous extract to OVA-sensitized rats caused a significant and very highly significant improvement of MDA levels in lungs, erythrocytes, GSH, GPx, GST, catalase and SOD. We notice a decrease in IL-4 in LBA and lungs alongside reduced inflammatory cell infiltration, mild bronchiolar dilation, mild alveolar edema and normal cell morphology allowing us to conclude on the effectiveness of anti-inflammatory activity of Roman chamomile.
