Abstract

Objectives: The aim of this study is to investigate the anti-inflammatory effects of Ojeok-san and compare the therapeutic effects according to its formation. Methods: We evaluated the anti-inflammatory effects of Ojeok-san using lipopolysaccharide (LPS) induced inflammatory animal model. Male SD rats were administered intra-orally with two different formulation types of Ojeok-san according to prescribed dosage. One hour later, to induce inflammatory responses, subsequent intra-peritoneal injection of LPS was conducted. After 5 hours later, serum TNF-α, IL-1β, IL-6 and PGE2 levels were measured by ELISA to assess the alteration of pro-inflammatory markers. Results: In our experiment, regardless of its formation, administration of Ojeok-san decreased TNF-α, IL-1β, IL-6 and PGE2 level in serum. Furthermore, LPS-induced toxicity of liver and kidney was not detected by Ojeok-san administration. Conclusions: The anti-inflammatory effect of Ojeok-san was shown in LPS-induced inflammatory model by decreasing pro-inflammatory markers, and there would be no significant difference in therapeutic effect between two formulation types of Ojeok-san.
