Abstract

An abundance of studies from different international groups have demonstrated tracers along linear pathways resembling meridians over the body surface of humans. All experiments of the studies have been conducted by injection of a radiotracer solution or tracer dyes in a volume of solution into acupuncture points (acupoints). The solution injected into acupoints produces much stronger mechanical stimuli than acupuncture, which causes axon reflex. Anatomical studies have demonstrated that acupoints/meridians exist higher number of small nerve fibers and blood vessels with rich nitric oxide (NO) and neuropeptides in the cutaneous tissues as structures for the biomolecules mediated axon reflexes. Recent advances have determined that NO and calcitonin generelated peptides play crucial roles in the comprehension of the axon reflex. The stimuli-evoked axon reflex and NOergic biomolecules/neuropeptides increase local blood flow with higher levels in acupoints/meridians, which move radioactive substances or tracer dyes in the skin and subcutaneous tissue under a linear path resembling acupoints and meridians, the important phenomena of meridians induced by the stimuli. The evidence and understanding of the biomolecular processes of the tracers along linear pathways resembling meridians have been summarized with an emphasis on recent developments of NO and neuropeptides mediating stimuli-evoked axon reflexes to increase local blood flow with higher levels in acupoints/meridians, which move radioactive substances or tracer dyes in the skin and subcutaneous tissue contributing to tracers along linear pathways resembling meridians in this mini-review.
