ABSTRACT
OBJECTIVE:To observe the effect of pathological lesion of renal tissue in rats with spontaneous hypertension (SHR),and study its mechanisms based on nuclear factorκB(NF-κB)signaling pathway. METHODS:21 SHR were randomly di-vided into model group and ICA low-dose,high-dose groups(20,40 mg/kg,denoted by ICA-L,ICA-H groups);other 7 homolo-gous Kyoto rats (WKY) were regarded as control group. All rats were intragastrically administrated,twice a day,for 11 weeks, rats in control group and model group received equal volume of double distilled water,ig. Pathological changes in renal tissue in each group were observed;Western blot method was used to detect protein expressions of p-NF-κB-p65,IκB and TNF-α in renal tissue. RESULTS:Compared with control group,model group showed disorder renal structure,narrow and irregular glomerular cysts;the protein expression of IκB was significantly down-regulated,protein expressions of p-NF-κB-p65 and TNF-α were signifi-cantly up-regulated(P0.05). CONCLUSIONS:ICA plays a role in improving renal pathological lesion in SHR,and the mechanism may be related to inhibiting NF-κB signaling pathway.
