Pathological change in microcirculation is a sign of diabetes. There are already successful cases in which qigong is effectively applied in curing diabetes. This experiment makes further exploration into the microcirculation changes that take place when external qi is used in curing diabetes. The rats are made to become ill with the method of making animal samples. Cure the rats with qigong; observe the changes in their blood sugar glycosuria, blood flow in the inner canthi and their hind legs. The result of the experiment shows that a) qigong can adjust the change in microcirculation and restore it to normal state; b) qigong external qi can change the index of urine sugar and restore it to normal state.

Diabetes is a kind of common disease and change in microcirculation is a sign in diahbetic patients.Impediment is found in many diabetic patients retina and in the microcirculation in their body. Their small arteries and blood capillaries are extensively bothered because of this.

Diabetes increases IDDM disability rate and death rate and deterorates NIDDM health state. Therefore the research into diabetes as well as its prevention are universally emphasized both home and abroad. Qigong has successfully cured many diabetic patients. Yet up to now further research which explores the mechanism of how qigong cures diabetes has not been reported. Therefore we make an explorative research into this mechanism from the perspective of microcirculation. The experiment is now reported as follows:

I. Object of experiment: Wister rats, 160g to 200g in weight, male and felale, illuminated for 10 hours a day,free to drink water and take food.

II. Prepare the samples of diabetes: Inject alloxan solution 12mg/100g rat’s weight

Into the stomachs of rats that are randomly chosen as the subjects of experiment. Five days later,the rats whose blood sugar is above 240mg/dl are chosen as the diabetic samples for this experiment. Then divide these diabetes control group. Moreover, we arrange a normal control group: Choose the rats in normal condition and only inject them with buffer solution.

III. Procedure of experiment: Blood sugar is measured once two days. Glycosuria is measured once a day. At the same time,blood flow in the limbs and that in the inner canthi of the rats are also measured. The time to measure is before qi transmission, during qi transmission and after qi transmission. Meanwhile, this is accornpanied with the observing microcirculation with microscope.

IV. Result of experiment:

  1. The blood flow in the body of diabetic rats displays a trend of changing from low to high with the passing of time. After about a week’s time,the blood flow begins to decrease(See Fig.1). The blood flow of the rats in the control group is relatively stable. The change of the blood in the therapeutic group tends to become normal after they have been trcated with qigong external qi.
  2. Comparison between the amount of blood flow in the inner canthi of the rats in the diabetes control group and in the diabetes qigong therapeutic group shows no evident difference.(P>0.05)(See Fig.2)
  3. Qigong has a relatively strong effect on the weight of the diabetic rats. The rats in the diabetes control group show great decrease in their weight(10g per day) at the beginning . Then they show the symptom of obesity. While the weight of the rats in the therapeutic group is relatively stable(Fig.3).
  4. The index of glycosuria in the diabetic rats displays an evident trend of decrease (P<0.01)when they are receiving qigong therapy and after they have received it(Fig.4), while the index of their blood sugar displays an unstable change.

V. Discussion:

The change in the amount of blood flow in the body of the diabetic rats show a tendency of going from low to high and then from high to low,which indicates the beginning process and the developing process of diabetes. External qi of qigong has an influence on this process. Its func tioning mechanism is probably that qigong cnhances the adjustment of the autonomous motion of the cndothelial cells of the blood vessel and improves the condition of microcirculation.

Qigong therapy has an evident effect on the diabetic rats’ weight and on the change in their glycosuria,which shows that qigong external qi has certain adjusting effect on diabetes. As to why the index of blood sugar has not shown evident decrease, it needs further observation and research.
