Abstract

The anti-inflammatory and antioxidant effects of Ocimum basilicum (O. basilicum) was shown previously. In the present study, the effect of O. basilicum on tracheal responsiveness (TR) to methacholine and ovalbumin (OVA), bronchoalveolar lavage fluid (BALF) levels of oxidant–antioxidant biomarkers as well as total and differential white blood cell (WBC) in sensitized rats was examined. Six groups of rats including control (group C), sensitized rats to OVA (group S), S groups treated with three concentrations of O. basilicum (0.75, 1.50, and 3.00 mg/ml) and one concentration of dexamethasone (1.25 μg/ml) (n = 8 for all groups) were studied. TR to methacholine and OVA, total WBC count, percentages of eosinophils, monocytes, neutrophils, and levels of oxidant biomarkers were significantly increased but other measured parameters were significantly decreased in group S compared to group C. TR to methacholine and OVA, percentages of eosinophils, monocytes, neutrophils, and levels of oxidant biomarkers were significantly decreased but lymphocytes and antioxidant biomarkers were significantly increased in S groups treated with dexamethasone and at least two higher concentrations of the extract compared to group S. Total WBC count was also decreased in treated S groups with dexamethasone and high extract concentration. The effect of extract on most measured parameters was significantly lower than dexamethasone treatment. The effects of two higher concentrations of the extract on most variables were significantly higher than the effect of low extract concentration. These results showed the concentration-dependent effect of O. basilicum on tracheal responses, lung inflammatory cells, and oxidant–antioxidant parameters in sensitized rats.
