Abstract
J$\bar{i}$n ji$\acute{e}$(根結) has been recognized as one of a meridian pathway. If you want to study a defense qi(衛氣) and nutrient qi(營氣)'s nature, function and operation, you could find a relationship of J$\bar{i}$n ji$\acute{e}$(根結) and the defense qi(衛氣). We proposed that, especially, J$\bar{i}$n ji$\acute{e}$(根結) has got a close relationship with a operation of the defense qi(衛氣). The ji$\acute{e}$(結) of three yang(三陽) located in ears and eyes, that are a starting point of the defense qi(衛氣) operation in the daytime and a one of five sense organs(五官). Gin, Liu, Zou and Ru (根, 溜, 注, 入) of the three yang(三陽) distinguished between the three yang(三陽) in the extremities. and in the symptoms of a disease of the three yang(三陽) on the bolt - leaf - hanges(關闔樞) theory, Greater yang(太陽) is related to the skin and flesh, Yang brightness(陽明) is related to the flesh and Lesser yang(少陽) is related to the muscle or bone. These skin, flesh, muscle and bone belonged to the five bodies(五體). The five bodies(五體) have relationship with the defense qi(衛氣)'s operation and function part. The ji$\acute{e}$(結) of three yin(三陰) located in neck, chest and abdomen. If we could catched the concepts on the ji$\acute{e}$(結) of three yin(三陰) and The Gin, Liu, Zou, Ru and ji$\acute{e}$(根, 溜, 注, 入, 結) position of three yang(三陽) altogether, we could suggested the theory of the entire area completed in the surface of body. so the defense qi(衛氣)'s protecting function of the whole body surface is achieved. In the symptoms of a disease of the three yin(三陰)'s the bolt - leaf - hanges(關闔樞) theory, greater yin(太陰) and reverting yin(厥陰)'s symptoms indicates the defense qi(衛氣)'s main action of a chest and abdomen. And lesser yin(少陰)' symptoms is about a vessle, that is not to mention on the five bodies(五體) of the three yang(三陽)'s symptoms, so here is mentioned the relationship of the defense qi(衛氣) and the five bodies(五體) strengthened. In the "J$\bar{i}$n ji$\acute{e}$ chapter(根結編) of Lin Shu(靈樞)", as the meridians of the foot (足經) was described, except the meridians of the hand(手經), it is reasonable to infer that the defense qi (衛氣) is relevant to the meridians of the foot(足經) than the meridians of the hand(手經).
