Abstract:

In the present study, we aimed to investigate the effects of Artemisia argyi essential oil (AO) on pulmonary hypertension (PH)inducedbymonocrotaline(MCT)andtoexploretheunderlying mechanism.A total of 80 Sprague-Dawley ratswererandomlydividedintofourgroups as follows:controlgroup, modelgroup,bosentan(0.1g/kg)groupandAO(0.1g/kg)group.After30dofexperiment, hemodynamicparameters,lungandrightventricle hypertrophy indexweredetermined. HEand Immunohistochemistrystainingoflungs were performedto detectthe injuriesandprotein expressions. Theresultsshowedthatlevels of mPAP,mRVP,maxRVP,wW,LI,RV and RVHI as well asthe expressionsofNF-κBp65andα-SMA were increased,smallpulmonaryarterythickened, the cavity of the arteriole narrowed, and there was marked infiltration of inflammatory cells in lungs of rats receiving MCT compared with the normal group. After the administration of AO, the levels of mPAP and mRVP were significantly decreased,and the wW, LI, LV+S and pulmonary arterial remodeling were markedly improved. The expression levels of NF-κB p65 and α-SMAwerereduced by AOcomparedwiththe modelgroup.Ourresultssuggestedthat AOreduced the progressionof PH induced byMCTthroughinhibiting the expressions of NF-κB p65 and α-SMA.
