We assessed the Master's single two-step test, postural blood pressure reflex, and autonomic nervous system manifestation in 112 essential hypertension patients and evaluated the results of low-frequency electroacupuncture therapy in 32 patients who exhibited the pressor type of diastolic blood pressure response to exercise. The following conclusions were drawn from the results. 1. The diastolic blood pressure response to exercise was the pressor type in 60 patients (54%) and the depressor type in 52 patients (46%). By catagory, it was the pressor type in 40 (56%) of the 72 patients in the group taking antihypertensive drugs, and the depressor type in 32 (44%). In the group of 38 patients taking diuretics, it was the pressor type in 20 patients (53%). In the group of 40 patients not taking autihypertensive drugs, 20 patients each displayed the pressor-type response and the depressor-type response. 2. The group with a pressor diastolic blood pressure response to exercise had higher systolic pressure when seated at rest than the depressor group, and the extent of the rise in systolic pressure in response to the exercise load was greater. The extent of the decrease in systolic blood pressure immediately after standing up in the postural blood pressure response test was less than in the depressor group. 3. The incidences of edema of the lower extremities, coldness of the lower extremities, and other autonomic nervous system symptoms were higher in the group with the pressor diastolic blood pressure response to exercise than in the depressor group. 4. The results of low-frequency electroacupuncture therapy on the 32 patients in the group with the pressor diastolic blood pressure response to exercise showed a depressor diastolic pressure response to exercise in 23 of the patients (72%). The period of treatment until the transition to the decreased pressure period was 5.5 months. While no improvement in the extent of the rise in systolic pressure in response to exercise was observed in the depressor stage, an increase in the extent of the decrease in systolic blood pressure immediately after standing up was observed in the postural blood pressure response test. From on the above results, it was found that some patients with pre-hypertension and mild hypertension showed the diastolic pressure response to the Master's single two step test that differed (in pressor type) from that of healthy subjects. In particular, it was shown that the blood pressure of some patients taking antihypertensive agents whose blood pressure was always within the normal range exhibited blood pressure responses to exercise that differed from those of healthy subjects. It was also found that 1-Hz, 10-minute low-frequency electroacupuncture therapy applied to the posterior surface of the leg (tibialis posterior muscle) is effective in normalizing the diastolic blood pressure response (shifting to the depressor type) to the Master's single two-step test in patients who displayed a pressor-type diastolic blood pressure response to exercise.
We subjected six male lumbago patients (average age of 58.2 years) to underwater therapeutic exercise with and without a hydropower system (Flow Machine (FM)) twice a week for 4 weeks (a total of 10 hours) at an interval of 10 weeks between the two therapeutic sessions. The FM produced running water (average speed of 0.9meter/second) in a temperature-controlled pool. The water temperature was kept to about 30°C, The subjects received a total of four examinations before and after these two therapeutic sessions. We compared the results of these two therapeutic sessions (under-water therapeutic exercise with FM and without FM) and obtained the conclusions described below. Improvements of obesity, anaerobic power, power around knee, vital capacity and total score in lumbago treatment (results of Japanese Orthopaedic Association) were observed more significantly (p<0.05) and rapidly with the use of FM than without FM. Further, increased HDL-cholesterol and decreased free fatty acid in blood were observed significantly (p<0.05) only for FM use. It was suggested that the resistance of running water, vibratile massage effect, and heat action of produced supersonic waves promoted the above improvements. We concluded that the hydropower system was useful in underwater therapeutic exercise on lumbago patients.
Prof. Motosaburo Masuyama has detailedly investigated the statistical distribution of more than 300 kinds of human biological traits, such as biochemical substances in blood. In his study, he found several empirical laws with respect to CV (coefficient of variation) of these traits, and proposed the two rules of human individual variability. The one was CV of fundamental blood components were less than 0.3, and another was the CV of these components did not differ by sex, race and age. In this paper, we first introduced his study. Second, we discussed the usefulness of his rules in the determination of initial dosis for patients with allergy. In addition, we tested the validity of his rules by using large size data obtained by the country-wide health check. We concluded that Masuyama's rules could apply many types of normal blood components of human being and be useful for designingg drug therapy, and for arranging clinical data. Since precise investigation performed by us showed that there are definite difference of CV between male and female, young and old, in many blood components, further study is needed.
