1. 111 cases with 30 to 38 weeks of gestation were admitted for observation. As a control, in the first two days after admission no therapy was conducted, so as to diminish the possibility of adding the spontaneous version in the therapeutic rate. In this period, the fetal positions of 11 cases were spontaneously restored to normal. It amounted to 9.99% per cent. In the remaining 100 cases no spontaneous version took place. Then moxibustion was applied to Zhiyin points once a day and for nine days. In the course of therapy, the fetal position of 71 cases were corrected with a successful rate being 71 per cent. Of the 29 unsuccessful cases there were 7 cases whose fetal position were corrected during moxibustion but the abnormal position resumed before discharge. It amounted to 24.1 per cent in the total unsuccessful cases. Of the above mentioned cases, 6 cases had adopted knee-chest position and moxibustion therapy. But there was no effect. After admission through moxibustion 5 cases were cured. The conclusion drawn from the observation of this series and that from prior observation was in agreement. But the therapeutic rate was somewhat low in the latter observation. It may be due to that the selection of cases and the criteria of evaluation are different from those in outpatient department.
2. Of 41 cases with abnormal fetal position some physiological parameters have been recorded simultaneously. These included respiratory activity, digital photoelectric plethysmogram, digital skin temperature, pulse rate, arterial blood pressure, and differential blood count. The heart rate of the fetus has also been counted. It was demonstrated that in the course of moxibustion the respiratory activity didn't change obviously. The blood vessels of the skin didn't constrict but dilated constantly. This was shown by the facts that the amplitude of pulse wave in the plethysmogram increased and the skin temperature was rising. The pulse rate didn't increase. The systolic and diastolic pressure didn't rise while the former even somewhat fell. The differential blood count didn't change significantly. Nevertheless the heart rate of the fetus evidently increased. These results suggested that the sympatho-adrenal system didn't stimulated by moxibustion. The increase of fetal heart rate at this time might be brought about by other ways.
3. The variations of some endocrine activities of 33 cases of these patients have been determined. It was found that the pre-moxibustion value of urinary 17- hydroxycorticosterone and 17-ketosteroid in the pregnant women was higher than that in the non-pregnant women. The post-moxibustion value of these hormones in the pregnant women significantly rose further. Pre- and post-moxibustion determination of the value of free plasmic corticosterone has shown the similar variations. These results suggested that moxibustion stimulated the hypophysial adrenocortical system.
4. The tracing of uterine activity was recorded in rabbits anesthetized with urethane. The moxibustion was applied to the bilateral points which corresponding with the Zhiyin points in human being. These procedures induced the increase in the activity of the uterus.
5. Moxibustion applied to Zhiyin points might reduce significantly the electric resistance of "Uterus", "Sanjiao", and "Endocrine" points on the ears. It was suggested that moxibustion might regulate the functions of uterus and endocrine. This view point of traditional Chinese medicine agreed with the fact that moxibustion stimulated the activities of the adrenal cortex and the uterus.
6. Based on the facts described above, it was presumed that moxibustion applied to the Zhiyin points, by means of stimulating the secretion of adrenal cortex, enhanced the uterine activity. At the same time, the fetal movement reinforced (and consequently the heart rate of the fetus increased). These dynamic factors favored the spontaneous correction of the fetal position.
