The effects of Crocus sativus extract on inhaled paraquat-induced lung inflammation, oxidative stress, pathological changes and tracheal responsiveness in rats
Paraquat is a green liquid toxin that is used in agriculture and can induce multi-organ including lung injury. Various pharmacological effects of Crocus sativus (C. sativus) were indicated in previous studies. In this research, the effects of C. sativus extract and pioglitazone on inhaled paraquat-i...

Zusammenfassung: | Paraquat is a green liquid toxin that is used in agriculture and can induce multi-organ including lung injury. Various pharmacological effects of Crocus sativus (C. sativus) were indicated in previous studies. In this research, the effects of C. sativus extract and pioglitazone on inhaled paraquat-induced lung inflammation, oxidative stress, pathological changes, and tracheal responsiveness were studied in rats. Eight groups of rats (n = 7 in each) including control (Ctrl), untreated paraquat aerosol exposed group (54 mg/m3, 8 times in alternate days), paraquat treated groups with dexamethasone (0.03 mg/kg/day, Dexa) as positive control, two doses of C. sativus extract (20 and 80 mg/kg/day, CS-20 and CS-80), pioglitazone (5 and 10 mg/kg/day, Pio-5 and Pio-10), and the combination of CS-20 + Pio-5 were studied. Total and differential WBC, levels of oxidant and antioxidant biomarkers in the BALF, lung tissue cytokine levels, tracheal responsiveness (TR), and pathological changes were measured. The levels of IFN-γ, IL-10, SOD, CAT, thiol, and EC50 were reduced, but MDA level, total and differential WBC count in the BALF and lung pathological changes were increased in the paraquat group (all, p |
