In the previous report, 24 pulses of Oriental medicine resolve themselves into six cardinal pulses; shallow-deep-empty, full, slow and frequent. Empty and full pulses are concerned with the pulse amplitude, blood fullness, and tenseness of blood vessels. The pulse amplitude and tenseness of blood vessels can be known to a certain extent by measurement of blood pressure, and 24 pulses can be more precisely analyzed by using the photoplethysmograph at the punctum puteus.
This time the author proposed to objectify the six cardinal positions of radial pulse diagnosis in the use of the photoplethysmograph (made by Fukuda Electric Company Ltd.)
Principle: From similitude between the photoplethysmogram and the pressure pulse wave, the author read the parts corresponding to the shallow, middle and deep pulses of the pressure pulse wave by the plethysmogram.
Method:(1) It was experimentally known that the incisura of the plethysmogram and the deep pulse of the pressure pulse wave reported in the 12 th paper of Study on Pulse Diagnosis were simultaneous.
(2) Tracing the plethysmogram and the electrocardiogram at the same time, do locate the main peak, tidal point or anacrotic point and incisura.
(3) The finger tip pulse wave is simultaneously traced by the photoplethysmograph with the two steps' corrective mechanism. This finger tip pulse wave makes the height of the pulse wave of the six cardinal positions corrective.
(4) The up-slope of the plethysmogram coincides with the diastolic period of the arterial tube, and so does the down-slope from the main peak to the incisura with the systolic period of the arterial tube. In the case that blood flowing conditions are homeostatic both in quality and in quantity, the up-slope amplitude is decided by hardness or softness of tissues between the skin and the shallow arterial tubular wall near the skin (containing a factor of the shallow pulse). The down-slope amplitude may likewise be considered as the vibration of the same artery near the skin, but it is decided by hardness or softness of the deeper arterial tubular wall and the extra-tubular tissues further down it (containing a factor of the deep pulse).
(5) Measuring every coefficient of traced pulse waves, the main peak of them is regarded as the common middle pulse.
In the catacrotic wave, the author finds the main peak height and the remainder subtracting the tidal point height from the main peak one. Then the latter from the former leaves the shallow pulse (which, namely, comes to the same height as the tidal point height), and the height from the tidal point to the incisura is the deep pulse.
In the anacrotic wave, the height of the anacrotic point is the shallow pulse and the height from that of the main peak to the incisura is the deep pulse.
In the monocrotic wave, the author computes two numbers, got in calculating the resistivity index (R. I.) relative to the elasticity index (E. I.), at the tidal point height and the anacrotic point height.
Tracing the absolute pulse wave and proportionally allotting the measured value on the basis.of the middle pulse of this pulse wave, it is theoretically thought that much more precise numerical value can be found.
In this method, it is possible to objectify the pulse diagnosis of the six cardinal positions quite unstimulatedly and much More easily.

The damage produced by peroxides which is inevitable for organisms living in oxygen atmosphere may be an important factor of aging and almost all diseases. By this hypothesis the standstill of modern medicine may be surmounted, and many things, including aero-ionotherapy, electrostatic remedy, etc., may be discussed systematically.
If we assume the important action of Japanese and Chinese drugs, previously unexplained by modern pharmacology, is to reduce the deleterious effects of peroxides, we would be able to clarify why they are so widely useful in many different diseases, and the unification of “kampo-medicine” and Occidental medicine may be attained.
Many findings suggest that cancer is a state in which the rejective reacton oforganisms is impaired through the lowering of defensive activity by harmful effects of peroxides.
Diabetes mellitus may be considered as a state of complex vicious cycle among peroxides, insufficiency of insulin action, and acidosis.
It may be quite natural that some prescriptions of “kampo-medicine” excellent in reducing the harmful effects of peroxides should be very effective in cancer as well as diabetes.
We can consider close relatioships with peroxides even in epilepsy, which is said to be also surprisingly cured by “saiko-keishi-to”, etc.
As to many other diseases we would be able to consider similarly.
