Abstract:
To study the role of meridians in the formation and development of diseases, a pathological model of obstructed channel was established by injecting polyacrylamide hydrogel. The effects of blocking low hydraulic resistance channel (LHRC), produced by injecting polyacrylamide hydrogel and by injecting normal saline, were compared by examining the change in transmission of interstitial fluid pressure wave. The results showed that there was significant decrease (P < 0.01) in interstitial fluid pressure wave after more than 0.5 ml polyacrylamide hydrogel was injected into the channel, whereas no significant changes were found after normal saline was injected or when the hydrogel was outside the channel. The above findings demonstrate that the low hydraulic resistance channel can be blocked by injecting certain amount of polyacrylamide hydrogel and a pathological model of obstructed channel has been established preliminarily.
