Biomechanical Study To The Meridian In Traditional Chinese Medicine

For studying the nature of the meridian in traditional Chinese medicine, Ideveloped extrovascular fluid pathway hypothesis put forward by a Japanese, Fujitaand built a hydromechanical model of meridian. In order to examining the model, Iimproved Guyton's method of measuring hydraulic conductance and found a lowhydraulic resistance(LHR) feature along meridians in rats and mini-pigs. For locatingthe LHR points, I developed two methods to measure the hydraulic resistance(HR)continuously in tissue with a single pressure transducer or two pressure transducers bywhich the LHR points along meridians were found on mini-pigs and human body. Ialso developed a method to measure the transmission of artificial interstitial fluidpressure wave(AIFPW) by which a better transmission of AIFPW was found alongmeridians in rats and between LHR points in mini-pigs. Combining the migration ofisotope along the LHR points in meridians, the existing of continuous LHR channelsalong meridians was confirmed. It was also shown lower interstitial fluid pressure onLHR points along meridians. Two physical model, gel-sol model and gel-fluid modelwere build to examine the electric resistance, hydraulic resistance and soundtransmission. It was shown that gel-sol model expressed only lower electric resistancefeature while gel-fluid model showed low electric resistance, low hydraulic and highsound transmission. As the three biophysical features were appeared on humanmeridian, the experiments support the fluid model of meridian and explain thebiophysical feature of meridian. Finally, the biological and medical significance ofmeridian as a material message channel to regulate whole life body were discussed.The study have a breakthrough in meridian nature and measuring methodology inbiomechanics and reach a high lever home and abroad.
