Acupuncture Attenuates Blood Pressure via Inducing the Expression of nNOS
Figure 3
Effect of acupuncture on nNOS in the ARC and vlPAG as detected by western blot and immunofluorescence. Representative gel images and summary data of nNOS (a) in the ARC and (b) in the vlPAG in SHR-Cont, WKY, SHR-SA, and SHR-LR3 groups. (c, d) Summary data show the mean fluorescence intensity of nNOS-positive neurons in the ARC and vlPAG. (e) Representative images show immunofluorescence of nNOS in the ARC and vlPAG. Data are presented as mean ± SD, n = 6 in each group. Scale bar = 50 μm. , SHR-Cont vs WKY; , SHR-Cont vs SHR-LR3; , SHR-LR3 vs SHR-SA. SHR-Cont: SHR rats without treatment; SHR-SA: SHR rats treated with acupuncture at nonacupoint; SHR-LR3: SHR rats treated with acupuncture at Taichong; ARC: arcuate nucleus; vlPAG: ventrolateral periaqueductal gray.
