Effect on the recovery of grasping power depending on the inserting direction of acupuncture was studied on 16 healthy person whose grasping power has weakened by continuous grasp of dynamometer.
1) As grasping power was not remarkably diminished by cross-insertion in comparison with non-treatment, the fromer method was considered to be far more effective than the latter in recovering the grasping power.
2) Cross-insertion was more effective than parallel-insertion in recovering the grasping power after checked injthe same method.
3) There was no rewarkable difference between non-treatment and parallel-insertion in the recovery of the grasping power.
Conclusion: The inserting direction of acupuncture has an important role in the effect of recovering the grasping power.

By means of indirect sphygmomanometer called “volume compensation technique” systolic and diastolic blood pressure in finger arteries were noninvasively and continuously measured during and after the “doshi” which is the acupuncture of the carotid sinus. After 15-min resting, 2-min puncture of the right and left carotid sinus was carried out in 23 healthy subjects (8 males and 15 females, aged 18-55). Finger arterial blood pressure was measured during the rest and the in-situ puncture, and then at 30 minutes after the withdrawing. For the control the dodged puncture of the carotid sinus was also made in other 6 healthy subjects (2 males and 4 females, aged 23-55).
Decreasing in blood pressure were observed during and after the doshi in 87% of the subjects. The mean magnitude of the decrease in the systolic and diastolic pressure at 15-21 minutes after the withdrawal of the needle were 12 and 10mmHg, respectively. Pulse pressure and heart rate showed little changes during the experiment. To the control dodged puncture, the maximum change in the systolic and diastolic pressure were 3.4 and 5.0mmHg, respectively, which were within the range of the physiological blood pressure variation. These data suggests that the blood pressure response to the “doshi” may not be induced by the vagal cardiac inhibition but by the change in peripheral vascular resistance.

During and after the “Toshi” which is the acupuncture of the carotid sinus, systolic and diastolic blood pressure were measured in the basal pharanx of finger arteries by means of indirect sphygmomanometer called the “volume compensation method”. After 15 minutes resting, 2 minutes acupuncture on both sides of the carotid sinus was carried out in 16 hypertensive subjects. Finger arterial pressure showed a significant decrease by about 14mmHg (mean) in systolic pressure and by 9mmHg (mean) in diastolic pressure during and after the acupuncture (p<0.05). The decrease in blood pressure showed a maximum at 15-20 minutes after the withdrawal of needles. Pulse pressure and heart rate did not show a significant change. These results were almost similar to those obtained in normotensive subjects. These data suggests that hypertensive subjects are also responsible to “Toshi” and that this effect may not be caused by the cardiac inhibition refrex but the change in vascular tonus.

During and after the LI4 and LI10 Acupuncture, the volume elastic modulus Ev in the basal phalanx of finger arteries were measured. Ev values were noninvasively obtained using a new type of plethysmograph called the “electric impedance-cuff” which can detect indirect arterial pressure and volume change in the artery. After 15 minutes of rest, 2 minutes acupuncture on LI4 and LI10 were carried out in 16 healthy subjects, respectively. Volume elastic modulus showed a significant decrease (p<0.01) during and after the LI10 Acupuncture. Its decrease were maintained at least 20 minutes after the withdrawal of the needle. While the Ev values did not show the typical change during and after the LI4 acupuncture. These date suggest that the elasticity of the peripheral wall was lagely affected by the LI10 acupuncture, and the effect was caused not only by peripheral reflex but by other factors.
