The Effect of Needle Electrode Electrical Stimulation on the Change of Caspase-3, 9 and Neuronal Nitric Oxide Synthase Immunoreactive Cells in the Sprague Dawley Rats
pp.47-63
In most tissues, apoptosis plays a pivotal role in normal development and in regulation of cell number. Therefore inappropriate apoptosis is revealed in a variety of diseases. This study was carried out to investigate the effects of acupuncture and needle electrode electrical stimulation on the change of caspase-3, 9 and neuronal nitric oxide synthase (nNOS) immunoreactive cells in the sprague dawley rats (SD rat). In immobilized SD rats (n=5), enhanced caspase-3 and caspase-9 expression were detected in the reticular part of substantia nigra, and enhanced nNOS was detected in the dorsolateral periaqueductal gray (DL-PAG) of midbrain and the paraventricular nucleus (PVN) of the hypothalamus using immunohistochemistry. Following the immobilization, acupuncture (n=5) and needle electrode electrical stimulation (n=5, 2 Hz) was applied at Hg (LI4) acupoint of SD rats, respectively. The stress-induced enhancement in the expression of caspase-3, 9 and nNOS were The present results demonstrate that and needle electrode electrical stimulation are effective in the modulation of expression of caspase-3, 9 and nNOS induced by immobilization.
