The present study was designed to investigate the effects of various electroacupuncture(EA) stimulation on NADPH-diaphorase and Neuropeptide Y(NPY) in the cerebral cortex of Sprague-Dawley Rats. We evaluated the changes of NADPH-d-positive neurons using a histochemical method and the changes of NPY-positive neurons using a double labeling immunohistochemical method. The staining intensities of NADPH-d-positive neuron and NPY-positive neurons were assessed in a quantitative fashion using a microdensitometrical method based on optical density by means of an image analyzer. As to frequency, the optical density of NADPH-d-positive neurons of 2Hz-1 time EA group was significantly higher than that of 100Hz-1 time EA group in M1, Cg, and that of 100Hz-3 times EA group was significantly higher than that of 2Hz-3 times EA group in Vi, Au, Cg and Ins. As to treatment-time, the optical density of NADPH-d-positive neurons of 2Hz-1 time EA group was higher than 2Hz-3 times EA group in Vi, Au, Cg and Ins. And in Vi 100Hz-1 time EA group and in M1 100Hz-3 times EA group was more efficient. As to frequency, the optical density of NPY-positive neurons of 2Hz-1 time was significantly higher in Vi, and that of 100Hz-1 EA group was higher in M1. And that of 2Hz-3 times EA group was higher than 100Hz-3 times EA group in Cg. As to treatment-time, the optical density of NPY-positive neurons of 2Hz-1 time EA group was significantly higer than 2Hz-3 times EA in S1, Vi, Au. And that of 100Hz-1 time EA group was significantly higher than that of 100Hz-3 time EA in Cg. The present results demonstrated that EA changes the activity in NO and NPY system in the cerebral cortex of SHR and EA stimulation, like frequency and treatment-time, is of importance for this effect.
