70 children (33 males, 37 female) from 6-14 years of age are randomly selected. The Nourometer RB type - 65 is used for the mesurement of the Neiguan (P6) current in tensity. The comparision between the current intensity at Neiguan and the neighbouring regions, between the two sex is made. The current intensity data of adult Neiguan is compared to our studied results. The correlation of the Neiguan point estimated distance and the height is calculated. It shows that the current average intensity is 94.54 +/- 16.7 mA (righ side) and 94.69 +/- 17.19 mA (left side). There is an significant difference of current intensity between the Neiguan Point and neighbouring regions (P< 0.001). The average data in the stied group is higher than in the adult (P<0.001). No significant difference of current intensity, area of point is shown in male and female, the left side and the right side (P>0.05). The correlation between the Neiguan estimated distance and the height is evident (r= 0.76)
Study Characteristics [Publication Type] ; Child

30 healthy male students from 19-24 years of age were selected randomly for studying some blood parameters under the effect of Neiguan EA: before, after 30 minutes and after 8 continuous EAs. 16 out of these subjects also received EA at points other than PC6. The blood parameters, including RBC, HBG, MCV, MCH, MCHC, reticulocytes, WBC, PLT, NEUT/L, LYMPH/L, MXD/L, RDW-SD, PDW, MPV, P-LCR were measured by automated Hematology analyzer K-4500 (made in Japan). Is was found that RBC, HBG, reticulocytes and hematocrit level increased remarkably after eight EAs (p<0.001 and p<0.05, respectively). The number of PLT decreased significantly 30 minutes after PC6 EA, in comparison with baseline (p<0.05). These changes were not observed after EA at points other than PC6
Blood ; Electroacupuncture

40 healthy male students aged 19-24 were selected randomly to study the influences of electric acupuncture in PC6 (Noi Quan point) on blood circular indicators 30 minutes before and after the puncture, and alone 1 8 day period of treatment (30minutes each day). 20 of these subjects were selected as control subject underwent an out of point acupuncture. Circular indicators include heart rate, systolic and diastolic blood pressures, ECG (time and altitude of P, QRS waves, T; time of PR, QT and TP intervals). Results showed that PC6 puncture reduced dramatically heart rate, systolic pressure 30 minutes after the procedure and after 8 day period of treatment. On ECG, the QT and TP time prolonged after this period. These changes of indicators were not detected on control group (without of point acupuncture).
