    [Abstract] Purpose To test and verify Qi-passage of meridians and

    collaterals, and clarify essence of meridians and collaterals. Methods

    Substance structures, functions and characteristics of Qi-passage of meridians

    and collaterals were studied by many experiments based on classical literature.

    Results In Qi-passage of meridians and collaterals there are many kinds of

    substance, macroscopic form, channel lines, space structures of external frame;

    and it also has interstitial functions of Wei-Qi moving, propagated sensation

    along meridians, changes of blood vessels, and lymph and immunity, and it is

    of interstitial characteristics of low electric resistance and good conduction,bi-directional motion, removing obstruction and Qi-passage communication with ......
