Measurement of NO levels and MPO activity. Effect of Rubiadin-1-methyl ether on measurement of NO levels (a) and MPO activity (b). S: healthy animals only treated with 0.9% sterile saline and vehicle (1% DMSO); LPS: (negative control) inflamed animals only stimulated with LPS (1 μg/mL) at intranasal route (i.n.).; Dexa: (positive control) animals pretreated with Dexamethasone (5 mg/kg, p.o.) 1 h before LPS administration; Rubiadin-1-methyl ether: animals pretreated with Rubiadin-1-methyl ether at doses at 3, 10, and 30 mg/kg (p.o.) 1 h before LPS administration. The results were expressed as the ; ; , , and compared with the LPS group.
