ABSTRACT
The effects of a PPAR-γ agonist, pioglitazone and Zataria multiflora (Z. multiflora) on inhaled paraquat (PQ)-induced lung oxidative stress, inflammation, pathological changes and tracheal responsiveness were examined. The study was carried out in control rats exposed to normal aerosol of saline, PQl and PQh groups exposed to aerosols of 27 and 54 mg/m3 PQ, groups exposed to high PQ concentration (PQh) and treated with 200 and 800 mg/kg/day Z. multiflora, 5 and 10 mg/kg/day pioglitazone, low doses of Z. multiflora + pioglitazone, and 0.03 mg/kg/day dexamethasone. Increased tracheal responsiveness, transforming growth factor beta (TGF-ß) and lung pathological changes due to PQh were significantly improved by high doses of Z. multiflora and pioglitazone, dexamethasone and extract + pioglitazone, (p < 0.05 to p < 0.001). In group treated with low doses of the extract + pioglitazone, the improvements of most measured variables were significantly higher than the low dose of two agents alone (p < 0.05 to p < 0.001). Z. multiflora improved lung injury induced by inhaled PQ similar to dexamethasone and pioglitazone which could be mediated by PPAR-γ receptor.
