1. Material and method:
Forty-four patients of about 60 years old (30 males and 11 females) with hypertension, ischemic heart disease or cardio insufficiency, etc. were divided into 2 groups to undergo the qigong training. The qigong exercise used was a combination of quiescent and dynamic forms. The training lasted 4-6 months.
The BJ values were computerized from 8 items by blood rheological examinations whole blood viscosity, hematocrit, cellular electrophoresis, sedimentation rate and its k value, plasma viscosity and reduction viscosity. The blood viscosity was considered normal when the BJ value was 50 and abnormal if the value reached 51-70, and 'warning' as it exceeded 71. In addition, we examined the rheocardiogram (RCG) in 39 cases, including SV, Co and CI.
2. Results and discussion:
(l) BJ value In the 1st group among 27 cases the mean BJ value was 69.41±26.85 before the training, and 54.25 ± 26.8 after the training. The Decrease was statistically significant (P<0.02), though the value remained in the abnormal range. In 12 cases of hypertension the Bp dropped from 141.5/81.7 mmHg to 127.3/75.3 mmHg when they had gone through the course of qigong training, in the meantime the blood viscosity decreased and the symptoms relieved.
The 2nd group included 17 cases. After the training the BJ values decreased from 66.2±22.8 to 62.8±23.9, although there was no significance in statistics, but in the control group (9 cases) its BJ values increased from 40.59±25.4 to 59.7±24.6 (P<0.05), the difference between them was found to be very significant on the X[square] test (P<0.025).
On the other hand, for some patients who did not do the exercise well, the results were negative.
(2) The changes of impedance rheogram: 39 cases were examined with RCG, it was found each index of RCG was increased; SV: from 85.02 ml to 112.8ml, CO: from 5.89L to 7.69L, CI: from 3.48 to 4.58. These changes were much significant after statistical treatment (the t test) (P<0.00l).
According to Liang Zijun et al, the blood viscosity is high in most cases of blood stasis and is lowered after the treatment with Chinese medicinal herbs to promote blood circulation and remove blood stasis. The qigong exercise, a non-medication treatment may act to promote blood circulation and remove blood stasis, and possibly, the cerebral cortex and neurohumoral factors may play a key role in its mechanism.
