ABSTRACT
Objective To study the effect of the reinforcing and reducing method of acupuncture reported in first Chapter the Nine Needles and Twelve Yuan of the Miraculous Pivot on interstitial fluid pressure (IFP) in subcutaneous tissue of minipig, and to investigate its biomechanical mechanism of regulating the interstitial fluid. Methods Nine healthy minipigs were randomly selected for reinforcing method (pull or press) and reducing method (wave a big pinhole), and tested on soft skin tissues of the abdomen. The IFP in the normal state (NS), the low volume (LV) state (by extracting interstitial fluid) and the high volume (HV) state (by injecting saline solution) was measured before and after acupuncture. Results In the normal state, pulling and pressing the needle could obviously increase IFP, while reducing method could significantly decrease IFP, leading to a rapid decrease in 5 min after acupuncture. In the LV state, pulling and pressing the needle could increase IFP. However, in 10 min after acupuncture, the descend rates of IFP were relatively slower. In the HV state, the reducing method could significantly decrease IFP, and the changing trend in 5 min after acupuncture was different from that of the control group. Conclusions The reinforcing and reducing method of acupuncture could increase or decrease IFP, which proved that the acupuncture method could regulate IFP in the opposite direction. The research findings provide a new scientific basis for using reinforcing and reducing method of acupuncture in clinic.
ABSTRACT
[Objective] To observe the influence of rats serum SOD and cardiac function with qi deficiency syndrome through the factors of the acupuncture point injection with different reinforcing and reducing methods. [Methods] To establish SD rat heart-qi deficiency syndrome model with the compound factors of the feeding, load forced swimming and large dose propranolol. The rats were randomly divided into blank control group, model group, Zusanli(St. 36) Shenqi Fuzheng injection reinforcing method group, Zusanli(St. 36) Shenqi Fuzheng injection reducing method group. Each acupoint injection of 0.20ml, one time a day, for 10 consecutive days. Determine of serum SOD activity values respectively and detect cardiac function correlated hemodynamic indexes. [Results] (1) The activity of serum SOD in model group rats was significantly lower than control group( P<0.01);Treated groups and model group had significant difference(P<0.05 or P<0.01);Zusanli(St. 36) injection reinforcing method group and Zusanli(St. 36) reducing method group had significant differences(P<0.01);(2) The cardiac function of rats in model group decreased significantly, corresponding heart function index of each treatment groups had changes and obvious differences. The maximum ventricular rats model of the internal pressure, left ventricular systolic pressure ,the maximum rate of rise of left ventricular pressure, heart rate and other indicators of Zusanli(St. 36) Shenqi Fuzheng injection reinforcing method group were more than indexes of Zusanli(St. 36) Shenqi Fuzheng injection reducing method group( P<0.01). [Conclusion] Acupoint injection of different reinforcing-reducing manipulations had different effect on the treatment of disease, and Zusanli(St. 36) injection reinforcement treatment of heart-qi deficiency syndrome model rats was significantly better than the other groups.
