[Survey of studies on tissue structures and biological characteristics of channel lines]

In order to comprehensively understand current situation about studies on channels and to open train of thought for the study, the relative literatures are analyzed and summarized from morphology, biophysics, biochemistry and so on. Probe into existing models of channel lines from nerves, blood vessels and nerves, gap junction, connective tissue; summarize biophysical characte-ristics of channels from temperature, loose connective tissue, biopressure effect, coherence electromagnetic field, etc.; and summarize biochemical characteristics of channels from ion concentration, exhalant of CO2, extracellular matrix and enzymology on the channel lines. Although the studies have not revealed essence of channel lines, these results reflect survey of studies on tissue structures and biological characteristics of channel lines at present.
