Biochemical and physiological effect of high voltage electric field was examined. Therapy by this method is considered to be a core technique in the field of rehabilitation and physical medicine.
Healthtron HES-30 (designed by the Hakuji Institute of Biological Science) was used to the patients with adult diseases, such as diabetes mellitus, hypertension, CVA, ischemic heart disease, obesity and gout, for 15 minutes in each treatment, 3 times a week.
1. Immediately after the treatment blood pressure decreased on the average by 18.6mmHg among the patients with systolic blood pressure of 160mmHg or more. But an increase of 5.5mmHg was observed among the patients with systolic blood pressure of 100mmHg or less. The varities in systolic blood pressure among the patients were significantly different from these among normotensives, who demonstrated the decrease of 5.8mmHg.
2. Percentage change in blood pressure, defined as the rate of the blood pressure reduced over the initial blood pressure, was positively correlated with the ren in ratio (r=0.8). The more related the blood pressure to sympathetic nerve, the more remarkable the percentage change.
3. Three of six patients with mild pituitary hormone insufficiency demonstrated symptomatic improvements together with the normalization of endocrinological distrubance. The urine sample indicated an increase of 17-OHCS and 17-KS. The serum cortisol also showed the normal U-shaped response. Rapid ACTH test showed the normalization of the previous delayed response. Pituitary reserve test also suggested the reactivation of the pituitary function.
4. Six (17%) of 35 patients with adult diseases showed the decreased TG level of 30mg/dl or more. Seven (27%) of 26 patients with high FFA level demonstrated the normal range. The improvement of the FFA level was observed in two of 4 patients with low FFA level due to hypofunction of the pituitary gland.
5. Total cholesterol level was not significantly altered. Among 18 patients with adult disease and with the low value of HDL-cholesterol, HDL-cholesterol level tended to increase
6. Thse particular findings were believed to suggest that the high voltage electric field has an effect of normalizing the abnormal blood pressure, and that the hypothalamus, pituitary gland and adrenal cortex were stimulated through the limbic system and reticular formation. Among the patients with adult disease, serum lipids seem to be affected in a favorable direction by this electric field.

The effect of the granules composed of Natril siccatus and herbal extracts in hydrotherapy was studied by recording skin surface temperature, deep body temperature from the intact skin, pletysmography, impedance pletysmography, blood pressure and subjective evaluation. These were measured before taking the testee into the Hubbart tank containing 0.0085% of herb granules at 40°C for 10 minutes, soon after taking a bath and at proper period until 2 hours.
The control study was done in simple water-bath in the same method. 30 testee were used for the test.
Results were as follows:
1. Skin surface temperature of H. G. group showed significant higher at the distal area of the extremities compaired with the control group.
2. Deep body temperature of H. G. group showed significant higher at right heel (10mm depth from the skin), palm (5mm) and calf (30mm) against the control.
3. The wave height of pletysmography of the index and the first toe of H. G. group was higher than the control at 100 minutes later.
4. IPG of H. G. group showed significant difference in upper and lower extremities against the control.
5. The change of the blood pressure showed no difference between two groups.
6. The subjective evaluation was scored and the t-test showed significant difference against the control, especially the difference was the most marked in utility feeling, and the effect of keeping warmth was in significant difference.
We may conclude that the H. G. in hydrotherapy has a sweet smell, make fell at home, keep warmth and play a role to promote blood circulation.
