ABSTRACT
Objective: To investigate the protective effect of phenolic compounds 4-hydroxybenzylideneacetone and (HBAc)3,4-dihydroxybenzylideneacetone (DHBAc) of Osmundae Rhizoma on the systemic inflammatory response syndrome (SIRS) in mice by establishing the mice model of SIRS.Method: BALB/c mice were randomly divided into the normal group,the SIRS model group and the different doses of HBAC and DHBAc group (25,50,100 μg·kg-3).Lipopolysaccharides (LPS) was injected intraperitoneally after 7 days of prophylactic administration.After 5 hours of modeling,the anus temperature,respiratory rate,the number of white blood cell (WBC) and platelets (PLT),WBC classification,glycolipid metabolism,inflammatory factor and signal transducing phosphorylated protein of lung were measured.Result: Intraperitoneal injection with LPS (6 mg·kg-1) in mice can significantly reduce the respiratory rate (PPPPPβ(PPPPPPPPPβ(PConclusion: The SIRS model can be established through intraperitoneal injection of LPS.HBAc and DHBAc have protective effects on endotoxin-induced SIRS in mice,and may exert anti-inflammatory effects through IκB and c-JUN pathways.
