Pathogenesis hallmarks in the lungs of COPD patients always contribute to causing inflammation and oxidative stress. Carotenoids, extracted from Sporidiobolus pararoseus, have antioxidant and antitumor effect. These carotenoids have a similar structure to lycopene, which is demonstrated effective in the treatment of lung inflammation. This presented work aims to investigate the anti-inflammatory and antioxidant functions of total carotenoids (TC), extracted from Sporidiobolus pararoseus, on mice under a short-term exposure of cigarette smoke. Forty-eight C57BL/6 male mice were divided into 6 groups (n=8): first group was control group exposed to ambient air, second group was CS group exposed to CS, third group was CS+LY18 group exposed to CS and treated with lycopene 18 mg/kg (CS+LY18), other groups (CS+TC18, CS+TC12, CS+TC9) exposed to CS and treated with (TC) at different doses (18, 12, 9 mg/kg) respectively. Treatment with TC especially at high dosage 18 mg/kg led to decrease the levels of MDA, GSH, activities of CAT, SOD in lung samples, as well as TNF-α and IL-6 levels in lungs and bronchoalveolar lavage fluid. In addition, it attenuated the morphological changes in the lungs. The high dose of TC showed a stronger effect than lycopene. These results demonstrated that TC from Sporidiobolus pararoseus have effective functions for acute lung inflammation induced by CS, which suggested a positive intervention for the treatment of COPD. http://pubs.sciepub.com/jfnr/6/12/4/jfnr-6-12-4.pdf Sporidiobolus pararoseus total carotenoids COPD cigarette smoke inflammation oxidative stress
