Popis: | PURPOSE: To investigate the effect of renal denervation (RDN) on the blood pressure, left ventricular hypertrophy and myocardial expression of TLR4/NF-κB in spontaneously hypertensive rats (SHR). METHODS: A total of 36 SHR were randomly assigned into control group (D0), RDN group (D) and sham group (S). 12 WKY rats of same age served as controls (WKY group). Rats in the D0 and WKY groups were sacrificed, but rats in the D and S group were sacrificed at one week and six weeks after surgery. The heart was collected and the left ventricle weighted followed by calculation of left ventricular mass index (LVMI). RESULTS: In the D0 group, the blood pressure, LVMI and protein expression of TLR4, NF-κB, TNF-α and IL-6 in the myocardium were markedly higher than that in the WKY group (p |
