Roots of Erigeron annuus Attenuate Acute Inflammation as Mediated with the Inhibition of NF-κB-Associated Nitric Oxide and Prostaglandin E₂ production

Figure 4

Inhibition of LPS-inducible iNOS and COX-2 by EER. (a) Representative iNOS and COX-2 immunoblottings. iNOS or COX-2 protein levels were monitored 18 h after treatment with LPS. (b) Relative iNOS and COX-2 protein levels. Data represents the mean ± S.E.M. from three separate experiments (significant as compared with vehicle-treated control, ^∗∗𝑃<0.01; significant as compared with LPS alone, ^##𝑃<0.01). EERs: extract of Erigeron annuus roots.
