Abstract

Acupuncture is the practice of inserting needles into the body to reduce pain or induce anesthesia. More broadly, acupuncture is a family of procedures involving the stimulation of anatomical locations on or in the skin by a variety of techniques. Employing acupuncture to treat human disease or maintain bodily condition has been practiced for thousands of years. However, the mechanism(s) of action of acupuncture at the various meridians are poorly understood. Most studies have indicated that acupuncture is able to increase blood flow. The acupuncture points have high electrical conductance and a relationship of the acupuncture points and meridians with the connective tissue planes and the perivascular space has also been suggested. Several studies employing the human and animal models have shown that acupuncture enhances the generation of nitric oxide (NO) and increases local circulation. Specifically, electroacupuncture (EA) seems to prevent the reduction in NO production from endothelial NO synthetase (eNOS) and neuronal NO synthase (nNOS) that is associated with hypertension and this process involves a stomachmeridian organ but not a non-stomach-meridian organ such as the liver. How can we explain the phenomena of EA and meridian effect? Here, we proposed a neurovascular transmission model for acupuncture induced NO. In this proposed model, the acupuncture stimulus is able to influence connective tissue via mechanical force transfer to the extracellular matrix (ECM). Through the ECM, the mechanotransduction stimulus can be translated or travel from the acupuncture points, which involve local tissue and cells. Cells in the local tissue that have received mechanotransduction induce different types of NO production that can induce changes in blood flow and local circulation. The local mechanical stress produced is coupled to a cyclic strain of the blood vessels and this could then change the frequency of resonance. According to the resonance theory, an oscillatory pattern of NO formation might occur in that specific organ. Therefore, the artery tree would then change the blood distribution and microcirculation of various organs and as a result further affect the production of NO.
