The effect of Zataria multiflora on pulmonary function tests, hematological and oxidant/antioxidant parameters in sulfur mustard exposed veterans, a randomized doubled-blind clinical trial.

Abstract：

BACKGROUND:Sulfur mustard is an alkylating agent which cause to short and long term incapacitations on various organs including lung. There is no definite treatment for lung disorders induced by SM exposure. In the present study, the preventive effect of Zataria multiflora (Z. multiflora) on hematological parameters, oxidant/antioxidant markers and pulmonary function tests (PFT) in veterans, 27-30 years after exposed to SM were studied. MATERIALS AND METHODS:Forty seven veterans allocated to three groups included: placebo group (P) and two groups treated with 5 and 10 mg/kg/day of Z. multiflora (Zat 5 and Zat 10). Drugs were prescribed in a double-blind manner for two months. Total and different WBC, hematological indices, oxidant/antioxidant markers and PFT values included; force vital capacity (FVC) and peak expiratory flow (PEF) were assessed at the beginning (step 0), one and two month (step I and II, respectively) after starting treatment. RESULTS:Total and different white blood cell in Zat 5 and 10 mg/kg treated groups in Step I and II were significantly decreased compared to Step 0 (p < 0.05 to p < 0.001). The levels of thiol, superoxide dismutase (SOD) and catalase (CAT) in Zat 5 and 10 mg/kg treated groups in step I and II were significantly increased (p < 0.05 to p < 0.001) but the level of malondialdehyde (MDA) significantly decreased in two treatment groups compared to Step 0 (p < 0.05 and p < 0.001 respectively). FVC and PEF values were significant increase in Zat 5 and 10 mg/kg treated groups in step I and II compared to step 0 (p < 0.05 to p < 0.001). Furthermore, FVC and PEF values in Zat 5 mg/kg were also increased in step II compared to step I (p < 0.01 for both). The percentage improvement of total and differential WBC, oxidant/antioxidant markers, FVC and PEF values during two moth treatment period significantly improved in the treated groups compared to the placebo group. CONCLUSION:Z. multiflora reduces inflammatory cells and oxidant biomarkers, while increase antioxidant biomarkers and improved PFT tests in SM exposed patients in a two moth treatment period.
