After an intervenous injection of Atropine the effects of the lung atrophia on the heart rate and intestinal movement were not significant but blood pressure was still elevated, indicating that the effects of the lung atrophia were associated with M receptor activity. 1—1 A STUDY OF PREVENTION OF CARDIAC F UNCTION : DISORDER DUE TO IMMEDIATE ENTRY INTO HIGH- LANDS BY QIGONG EXERCISE Mo Feifan, Xu Yongchun, Lu Yongpin, Xu Guang Clinical Experimental Center , Chengdu General Army Hospital * Change of cardiac function might happen to persons living on plains who quickly enter the Tibeten plateau. Before entering the highlands, 66 persons were divided into two groups; the qigong group, including 32 young men who had taken exercise of Qiyuan Qigong for 4 weeks. The control group, including 34 persons did exercise to radio music. The results showed that in the highlands, the attack rate of altitude stress and abnormal blood pressure, heart rate, oxygen consumption and the weighted integral value of symptoms due to high- lands, were statistically lower in the qigong group than in the control group; the index of the cardiac function of both the two groups statistically lowered at Tibet on plateau and TPR in the qigong group was statistically lower than in the control group, but the indexes such as’ sI, cl, Ac, HI of the qigong group were statistically higher than those of the control group. . It is suggested that exercise with qigong should prevent cardiac function disorder due to high-: land and needs in-depth studies. A STUDY OF PREVENTION OF MICROCIRCULATING _ DISORDERS OF PILOTS IN HIGHLANDS BY QIGONG Mo Feifan, Wan Lurong, Jia Zizi, Xu Guang Clinical Experimental Center, Chengdu General Army Hospital Microcirculating disorders might happen to persons living on plains who quickly enter the Tibeten plateau due to deficiency in oxygen. Some airforce pilots were randomly divided into two groups; the qigong group, including 22 persons who had practised Qiyuan Qigong exercise for eight weeks; the control group, including 18 persons who had exercised with common physical trainning for eight weeks, before entering the Tibeten plateau and their symptoms due to high mountains microcirculation of epes tongue and nail fold, temperature at Laogong (P8) of the left hand were measured before and after their entering the Tibeten plateau. The results showed that the integral value of symptoms due to high mountains in “78° Approved For Release 2000/08/15 : CIA-RDP96-00792R000400430001-6

It is suggested that qigong exercise should redress altitude stress, prevent microcirculation disorders, strengthen the suit capacity of human body and shorten the suit time. In a word, qigong is an economic, convenient exercise which may prevent altitude stress and be easy to be popu- larized in the army. 1—13 ASTUDY OF THE INFLUENCE OF YUAN JI QIGONG ON PHYSICAL AND MENTAL HEALTH OF STUDENTS Wu Hanrong, Yang Limin, Zhou Jianghong, Chen Xiang, Zhen Erkang Tongji Medical University, Hubei Province Qigong is the valuable heritage of the Chinese culture, which has unique function in prevent- ing and curing diseases and improving health. It has been reported that the great results have been achieved and the influence of human beings’ physiological and psychological indexes given by Yuan Ji Qigong in the combination of Yuan Ji Qigong and modern science. But we fail to read the accounts of comprehensive effects on human beings’ physiology, psychology and sport ability. In order to study the effects of Yuan Ji Qigong on the physical and mental health, we made the primary study and comparison of the changes in Tongji Medical Univer- sity in physiology, psychology and sport ability of students between the practicing group and the control group before and after practising Yuan ji Qigong from November of 1991 to April of 1992. The results showed ; 1. The students in the practice group didn't perform Yuan Ji Qigong before they ran 800m, through a short period for 20’ 40’ after running 800m, lactic acid clean rates in blood were 20.1% and 57.1% respectively. After practising Yuan Ji Qigong lactic acid clean rates in blood were 36.6% and 80.3% respectively. The difference between the states after and before practising Yuan Ji Qigong was statistically significant (p<0. 05). The result indicated that practising Yuan Ji Qigong and listening to Yuan Ji Qigong music could remove students’ tiredness and increase students’ lactic acid clean rates after sports and speed up physical re- covery. 2. Before practising Yuan Ji Qigong the step index of the students was 45. 2 in the prac- tice group. After practising Yuan Ji Qigong the step index of students is 64.2. The differ- ence between the two groups was statistically significant (p<.0. 01). The results showed Yuan Ji Qigong can improve the circulation, raise the ability of heart storage, so doing Yuan © 79 © Approved For Release 2000/08/15 : CIA-RDP96-00792R000400430001-6

Before practising Yuan Ji Qigong, the grades of the forceful symptom, the sensitivitry of relationship between people, the gloom, the anxiety, the hostile to the others were 1. 24, 1.1, 0.9, 0.75, 0. 83 respectively, but after practising Yuan Ji Qigong the grades were 0. 98, 0. 85, 0.68, 0.55, 0. 64 respectively. The results showed that practising Yuan Ji Qigong can improve the mental state and help them overcome their obstacle in behavior and emotion. 1— —14 INFLUENCE OF MENTAL ACTIVITY ON THE RESPIRA- TION REGULATION DURING QIGONG EXERCISE Sun Fuli, Jiao Yan, Wang Juemin, Cheng Lianhu Xiyuan Hospital, China Academy of Traditional Chinese Medicine, Beijing 10091 Baoding Qigong Institute, Baoding 071000 Ancient qigong literature described mental activity as “fire”, respiration-regulation as “wind”, and considered that the integrated “fire” and “wind” can produce a marvellous phys- iological action. The course of mind concentration on respiration regulation was called “WU HUO PENG LIAN”, the process of mental quiescence and smooth breath was called “WEN HUO MU YU”. They played a very important role in some processes of qigong exercise. Physiological information can be derived from the instantaneous heart rate, which de- pends upon the interaction between the pacemarker properties of cardiac tissue and autonom- ic nervous system activity. Sophisticated analysis of R-R interval variability by the power spectrum method reveals that there are two major components; a high frequency component of around 0. 3Hz, corresponding to respiratory sinus arrhythmia, and a low frequency com- ponent of around 0. 1 Hz, which is called Mayer wave and reflects the spontaneous oscilla-: tions of the cardiovascular system. Recent studies in this field showed that the two spectrum peaks of low and high frequencies are mediated separately by sympathetic and vagal activi-. ties. Thus, the ratio of low- to high-frequency could be a marker for assessing the change of sympatho-vagal balance. In addition, these spectrum peaks could affect each other in a cer- tain condition, and forms the phenomenon as the “entrainment of frequency” described in the physics term. In this study, the relation between the mental activity and respiration regulation was ob- served by using spectrum analysis for R-R interval veriability on 60 volunteers. The results| showed while respiratory frequency was regulated lower down towards the cardiac oscillatory frequency » the amplitude of the respiratory spectrum peak increased significantly, indicating the vagal activity to enhance. On the contrary, when the respiration regulation frequency in- creased, its amplitude decreased and the ratio of low- to high- frequency increased, indicat- | ing the sympathetic activity excited. It reveals that the change of respiratory frequency con- . 80 . Approved For Release 2000/08/15 : CIA-RDP96-00792R000400430001 6

However, when the mental activity was quiescent and the respiration regulation was passive» the natural oscillation of cardiovascular system increased, both the respiration regulation frequency and its amplitude decreased. The spectrum peak of respiration regulation keeps to the natural oscillation of the cardiovascular system by reaching the psychosomatic tranquil state. At last, the two spectrum components combined to an united peak around 0. 1 Hz, which indicates the sympatho-vagal balance came into a special state. In conclusion, it can be verified by using the method of current experimental physiology for the relation between the mental activity and respiration regulation described in ancient qigong literature. 1—15 EXPERIMENTAL RESEARCHES ON QIGONG’S EFFECT ON THE DIGESTIVE TRACT Yu Min® ,Huo Jiming® ,Wang Yuain® , Zhang Guifang® ,Chi Zhenfu (1)Pharmaceutical Department of Jiamusi Medical College (2)Research Department of Somatic Science of Jiamusi Medical College (3)Microbiologic Teaching and Researching Section of Jiamusi Medical College A section of intestine in vitro,the change of gallbladder under the ultrasound B and the intestinal microflora were analysed in this paper. Qigong effect on the mechanical digestion , chemical digestion and intestinal microecology was studied respectively. 1. The action of qigong on a length of intestine in vitro; Qigong masters emitted qi to the intestine under constant temperature for 10 min. Oxygen was given. The contractive range obviously increased. 15 min later qigong masters finished qi emission, its contractive range continued going up,but its contractive frequency did not change. 2. The gallbladder’ s changing before and after meditation under ultrasound B; The hori- zontal diameter and wall thickness of the gallbladders before,in and after meditation in 12 people who were doing qigong exercise were examined with a Shimadzu SDV ultrasound in- strument. The results showed that the horizontal diameter of the gallbladders increased and the wall thickness decreased 5 min after meditation. It reveals that the secretion of the bile grows in quantity. 3. Qigong effect on the intestinal microflora; When feces of 7 exercisers over a long peri- od were assayed. The number of pathogenic bacteria such as intestinal bacille,cocci ete. were fewer than that of the control group, while the number of the beneficial anaerobes, for in- stance, lactobacilli, bifidobacteria and so on, was higher compared with the qigong group.
