Effect of Needling Point Zhongji (CV3) on Spectrum of Intravesical Pressure

To study the quantization indexes of acupuncture regulative effect on bladder function,rabbits were given cholinergic stimulant by intravenous drip to make the detrusor of bladder overacfivity,the catheters were put into the bladder of rabbits,and normal saline was affused into the bladder while the intravesical pressure was observed.To electro-needling point zhongji(CV3) of the rabbits,the time domain wave and the spectrum of the intravesical pressure were analyzed.The results showed that the time domain wave of the intravesical pressure during the filling of bladder was inapparent,and the spectrum analysis indicated that frequency domain of the intravesical pressure was mostly within 1 Hz,the energy of 0.4 Hz to 0.6 Hz period was obviously decreased by needling CV3.Conclusin: Spectrum analysis could offer quantization indexes of acupuncture regulative effect on bladder function.
