RESUMO
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.
RESUMO
Artemisinin was isolated from traditional Chinese herb Artemisia annua for treating malaria. A series of derivatives,like dihydroartemisinin,artesunate,artemether,artether,had the same core chemical structure,and sesquiterpene lactone containing peroxide bridge constitute the basic chemical structure. Besides anti-malaria,artemisinin family drugs were found to ameliorate many different diseases,which have attracted wide attention in recent years. Among different diseases,artemisinin family drugs were found to have T lymphocytes immunomodulation effects,including activation,proliferation,differentiation,apoptosis and subsets function. Because T cell immunologic response is the key point of many diseases,and impact the pathogenic process,therapeutic effect and prognosis,the drug studies with it as the target have become hotspots in recent years. Studies of artemisinin family drug on T cell immunomodulation were still at the initial stage and involved in different disease; furthermore,T cell immune process involves complicated molecular mechanism,it is imperative to summarize the advance of current studies for further systematic explanation and exploration of their characteristics and mechanisms. This article will summarize the research progress of artemisinin family drugs for malaria,autoimmune disease,hypersensitivity reaction,tumor,schistosomiasis and AIDS relating to T cell immune modulation,so as to provide basic and professional reference for related research and application.
