Emitted qi has been found to have a good curative effect on soft tissue injuries, such as muscle soreness, scleroma in muscles, acute muscle sprain. muscle contusion and pains. Fracture is also a common injury in sports medicine. We have cured some cases of fracture with emitted qi. The purpose of this experiment was to investigate the biological effect of the emitted qi on healing of fracture.
16 healthy male rabbits, weighing between 1.9-2.5 kg, were divided into two groups the control group and the emitted qi group. Under a septic condition and with intravenous injection of thiopental sodium of 30-40 mg/kg, the fracture with a gap of 3 mm was made at the junction of the middle and lower thirds of the left radius distal to the insertion of the round pronator muscle. The rabbits in the emitted qi group were given the emitted qi treatment for 3 minutes per day after fracture. X-ray films were taken every week. On the 2nd, 3rd. 4th, 5th week after fracture, two animals of each group were killed and specimens for light microscope study were fixed with 1O% neutral formalin, decalicified with 75 % EDTA, dehydrated with graded series alcohol, embeded with paraffin. Then the specimens were cut into slices of 8 mm thickness along vertical axis of radius, strained with H. E. and studied by a light microscope.
The morphological observations are as follows:
1. Based on some radiographic indexes, such as reaction of fracture section, periosteal reaction and amount of callus formation and callus density, we found that the amount and density of callus formation were better in the emitted qi group than in the control group . The difference was significant in the 2nd week (n=16, P<O.Ol) and 3rd week (n=12, P<O.05).
2. Ultrathin sections were produced with LKB-III ultratome, strained with uranyl acetate and lead citrate, and studied with a DXB1_12 electronmicroscope (EM). With EM, the changes in myofibrils were observed and photographed ( X 13000). Injured myofibril volume density in the pictures were calculated by means of point-count method.
3. The ultrastructural examination revealed that overstrain caused pathological changes, such as muscle fibers edema, shortening or lengthening of sarcomas, disorganization, breaking and disappearance of myofibrils as well as Z lines, accompanied by edema and damage of mitochondria. These changes could be seen less frequently in the emitted qi group than in the control group. The result of quantitative analysis showed that the volume density of myofibrils of the injured muscle in the emitted qi group was 2.47%, and that in the control group was 20.41%. The difference of density between the two groups was significant (P<0.01). We conclude that the emitted qi has a better preventive and therapeutic effects on ultratrauma in overstrained muscles.
At present, although the precise mechanism of the emitted qi is not clear, it has been found by electronic detectors that it may involve some kind of electromagnetic fields, such as low-frequency modulation waves of infrared, low-frequency electromagnetic wave, microwave, etc. Scientists discovered that weaker pulse magnetic field or low-frequency electromagnetic field has a higher bioactivity in treatment of bone and muscle injuries. Therefore, we think that some kind of electromagnetic contents in the emitted qi may influence the electromagnetic field of an organism and produce such preventive and therapeutic effects.
