In recent years there is much talk of prevention or early detection of diseases. The number of persons undergoing complete general testing and physical examinations has increased. However among the patients coming to the acupuncture clinic are persons who upon undergoing physical examinations at hospitals were told results showed nothing wrong and yet they continue to experimence subjective or non-objective symptoms. Concerned with this problem I checked the distribution of patients coming to the clinic.
1, 838 persons from among the 2, 297 new patients who visited our clinic during the 5 years, 2-months from Oct. 1, 1973 to Dec. 30, 1980 who had been diagnosed by a physician were used as subjects of this examination. Results indicated that of these 1, 838 persons 258 or in other words, 14% of the subjects were experiencing subjective or non-objective symptoms.
I reported on the 1, 649 patients who visited the clinic in 1974, however, as together with this discussion some interesting results concerning the patient distribution of non-“subjective and non-objective symptom” patients were obtained, I'd like to also report on these.

Pulse diagnosis is one of the most important diagnostic method in Chinese medicine, however, the expression of this diagnostic technique is subjective and cannot be in this form compared with modern medicine. Many attempts to describe the pulse conditions objectively have been made, however, there has been little success.
Any wave can be described by the frequency distribution of the energy, according to Fourier. Using this method, we tried to objectify the pulse wave. For the recording of the pulse, a pick-up (Nihon Kohden TF-11S) was fixed in a place at the radial artery and pressure applied using a micromanipulator. The output was put into a data recorder through an amplifier and monitored by an oscillograph. Data was then processed using computer (HITAC-20) and power spectrums were displayed.
In the above described method, the minimum and maximum force which should be applied to detect the pulse wave varied from person to person. The range was from 10-50g and 400-600g for minimum and maximum, respectively. This can be considered as individual variations of so called “floating and sunken” pulses. The best shape of pulse waves were obtained with 100-300g of pressure.
A typical power spectrum of pulse wave was composed of standard sine curve (approximately 1Hz, basic wave) and its harmonics. Sharply peaked waves occured when the basic component was great and oppositely, the flatter waves contained abundant of harmonics. The ratio of the basic wave to its harmonics represents the characteristics of wave pattern, i. e., objective description of pulse conditions can be made.
We will then, investigate the correspondence of the recordings to the expressions in the Chinese medicine, influences of acupuncture, etc.

In this study we investigated the effects of electric acupuncture on in vivo function of cell-mediated immunity, especially Mountoux reaction (PPD skin test) in normal individuals.
Normal young adults were inserted Chinese needles into two specific needle points, which were determined by means of chinese diagnostic procedures of radial arteries. The electric current were 5Hz, 2volt for 5 minutes.
One of the normal individuals showed negative reaction of PPD skin test, and 6 of them showed weak positive reaction. These 7 persons were done the second PPD skin test at 2 months after initial skin test, and they were treated with electric acupuncture immediately before skin test. 3 of them showed strong positive reaction of second skin test with electric acupuncture. Moreover, area of erythema induced by skin reaction become larger than first skin test in all of them. These results suggested that electric acupuncture would augment the in vivo cell-mediated immune reaction.

Pulse diagnosis has been taking an important part, together with the other diagnostic techniques, for determination of symptoms and treatment of patients with acupuncture. However, the traditional expression of pulse is complicated and subjective, so that the understanding of pulse diagnosis in termes of modern medicine is almost impossible. We tried to objectify the expression of pulse wave.
The pulse wave recorded from the six positions on radial artery according to the method described in Chinese Medicine through a force transducer. The recordings were processed for Fourier analysis utilizing a computer system. Characteristics of the pulse wave can be expressed quantitatively as a form of power spectrum of its components. The preliminary results of this study was reported at the 31th annual meeting of the Japan Society of Acupuncture. This time, we report the analysis on the basic pulse waves which have been recognized as negative-positive and imaginaryreal pulses.
Method
The subjects were normal volunteers of 36 males and 17. females. A force tranducer (Nihon Kohden TF-11S) Equipped with 0.52cm² of sensitive area was placed on the radial artery under the pressure ranging from 20 to 550gr. The pulse wave thus recorded was led into the electronic computer (HITAC-20) to obtain the power spectrum of the frequencies.
Results
It was found that characteristics of the six kinds of pulse waves, i. e., floating-sunken, smooth-leap and slow-fast types, can be represented quantitatively in terms of frequency histogram. Further, a possibility to express so called "complex pulse" in Chinese Medicine by this method is suggested.

We investgated the effect of electric acupuncture on peripheral T lymphocyte subset from normal individuals, analysed by laser flow cytometric system with monoclonal antibodies for human T lymphocyte subset.
OKT3⁺ cells (peripheral T cells) and OKT4⁺ cells (helper/inducer cells) did not show any changes after electric acupuncture. OKT8⁺ cells (suprressor/cytotoxic T cells), however, OKT11⁺ cells (E rosette positive T cells) and Leu7⁺ cells (natural killer cells) increased and Leu11⁺ cells (another population of natural killer cells) decreased after electric acupuncture.
These changes of peripheral T lymphocyte subsets would suggest that electric acupuncture effects human immune system.

In our clinic, blood pressure measurement has been done for many patients with various chief complaints. Acupuncture treatment was undertaken to improve their chief complaints according to Kurono's whole-body adjustment. We carried out a research paying attention to the fact that the patients with elevations of the blood pressure at the first visit showed a tendency to gradual decrease of the values.
According to the values of the first measurement, patients were divided into two groups in accordance with WHO's criteria: Hypertension group and Boundary one.
The first measurement velues and the averaged values of the following seven measurements undertaken before treatment were compared using histgram and t-test.
The descent of the blood pressure was seen in both Hypertension and Boundary group.

Recently it is well known that human immune system is regulated by various other biological response systems; endocrine and nervous system. We have investigated the effect of electric acupuncture on human immune system for several years. Those studies suggest that electric acupuncture affects human immune system via neuro-immune system. In the present study we investigated the effect of endorphin on human peripheral lymphocytes.
At the present concentration of endorphin and naloxone there were no effect on viability of lymphocytes. ³H-thymidine up take of unstimulated lymphocytes were suppressed by a appropriate concentration of endorphin or naloxone. The mitogenic responsiveness of peripheral lymphocytes was suppressed at usual concentration of naloxone and higher concentration of endorphin.
In these data suggested that both of intrisic and extrinsic endorphin regulated human lymphocyte responsiveness.
