Consideration on the secret of Meridian points by the description about acupuncture depth in a classic "Zhen-jiu-jia-yi-jing" / 全日本鍼灸学会雑誌

In a classic “Zhen-jiu-jia-yi-jing” position and name on relating to Meridian points has been touched on. That includes the depth of acupuncture's insertion. Based on this, this effort to look for those Meridian points ensured. In addition comparision between acupuncture depth, its position and the differences in Meridian have also been done. All together these are 347 hols, maximan being the 9mm which accounts for 135 (39%), second comes the 15mm hole of 49 (14%), third are 38 (11%) for the 12mm Meridian-points. The depth until 15mm accounts for 75% of the total. Face, upper limbs, the head and chest are especially shallow.<br>Meridian points of depth in 45mm to 75mm amounts to 3% as a whole. They are located in the lower abdominal and sacral regions. The deepest acupuncture points of the meridian are in the Conception Vessel Meridian, The Bladder Meridian and The Stomack Meridian. In the limbs, the Yin Meridian is especially shallow, while the Yong Meridian deep. Pertaining to the underlying reason for depth of different points, what depth meaning what the thickness of skin has likewise been studied. It seems that acupuncture depth and skin thickness goes parallel.

The Two-point Fused Sensory Area of the Skin and the Effect of Acupuncture Stimulation / 全日本鍼灸学会雑誌

The two-point fused sensory area (fused area) was calculated from two-point fused distance. The fused area was enlarged by acupuncture stimulation. This enlargement of the fused area by acupuncture was explained on the point of the central nervous mechanisms.<br>Applying the two points of touch and pressure stimuli to the skin, the threshold separation required for the two stimuli to be noticed as one rather than two points was determined. On the same region of the body, three longitudinally combined points and one transversally combined point were measured and the area which was surrounded by them was calculated.<br>The fused area was more enlarged through the touch stimuli than through the pressure ones. On the upper limbs, the shape of the fused area was like an oblong and the area was smaller at the peripheral part than the central part. Acupuncture stimulation enlarged the fused area. This was concerned that the lateral inhibition could not be worked in the tract by impulses which were generated by acupuncture.
