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.

In this study we investigated the effects of electric acupuncture on in vitro functions of lymphocytes, especially mitogen responses and natural killer (NK) activities of peripheral lymphocytes from 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. There was a tendency to increase phytohaemoaggultinin (PHA) or concanavalin A (Con A) responses of lymphocytes immediatly after acupuncture, but no significant changes. However, there was a significant (p=0.05) increase of pookweed.mitogen (PWM) responses immediatly after acupuncture. NK activities were measured by a ⁵¹Cr release assays. NK activities were enhanced significantly (p=0.05) immediatry after acupuncture. Moreover these changes of mitogen responses and NK activities were shown only when stimulated at specific acupuncture points. Most prominent changes were observed immediately after acupuncture, and the changes in parts continued after 4 hours.

A baby girl with a low birth weight was given a diagnosis of congenital bicuspid aortic stenosis and mitral valve prolapse. At the age of 40 days, she underwent balloon aortic valvotomy, but significant aortic regurgitation appeared afterwards. Another surgical intervention became necessary by the age of 20 months (weight, 5.7 kg), because of intractable heart failure mostly caused by exacerbated mitral regurgitation. We performed a leaflet extension valvuloplasty for the small bicuspid aortic valve using an autologous pericardium treated by glutaraldehyde. The mitral valve was replaced with an ATS-16AP valve. Although her postoperative course was complicated with mitral paravalvular leakage and poor left ventricular function, she was discharged from hospital 6 months post operatevely. Leaflet extension valvuloplasty is a surgical option for infants with a small aortic annulus, but the procedure could be the only solution in cases when Konno or Ross techniques are not suitable.

It is well known that acupuncture has a curative effect for some chronic diseases such as neuralgy or lumbago, if it is administered carefully in terms of the patient. However, the mechanism of acupuncture's effectiveness remains obscure.
In this experiment, using mice of the ICR strain, the protective effect of acupuncture against mouse liver injury was investigated following the administration of carbon tetrachloride.
Experiment I (Fig. 1): One hundred mice were divided into two groups. The first group of animals was administered carbon tetrachloride ip on day 18. The second group was treated a total of six times with acupuncture every three days from the first experimental day to day 18 at the points of Tienshu (ST-25), Feishu (BL-13), Hsinshu (BL-15), Kanshu (BL-18), Pishu (BL-20), Weishu (BL-21), Chimen (LV-14), Chihai (CV-6), Chungwan (CV-12) and Chuchueh (CV-14) (Figs. 3, 4). Fllowing the administration of carbon tetrachloride, the mouse mortality was checked. All of the animals of the first group (carbon tetrachloride administration only) died within 72 hours, but only 84% of the animals of the second group (carbon tetrachloride and acupuncture treatments) died (Fig. 2).
Experiment II (Fig. 1): One hundred and 60 mice were divided into 5 groups. The first group was used for the control (Fig. 5). The second group was injected ip with carbon tetrachloride of 3.47g/Kg BW on day 17. The third group was given a total of 5 acupuncture treatments every three days at the points as mentioned in Experiment I, and carbon tetrachloride was injected as in the second group.
The fourth group was injected a total of 5 times with 0.0004mg levallorphan (an anti-opiate) every three days. The fifth group was given acupuncture treatments like the third group; levallorphan was injected before the acupuncture, and also carbon tetrachloride was injected on day 17 as in the second or third, group.
The animals were sacrificed on day 20, and the liver tissues were treated as usual and then observed by electron microscopy.
The hepatocytes of the second group (carbon tetrachloride only) were heavily injured, and contained, a number of fat droplets, autophagic vacuoles and degenerated cell organelles (Figs. 6, 7, 8, 9). On the other hand, the hepatocytes of the third group (carbon tetrachloride and acupuncture treatments) were almost normal, and without any cell injury (Figs. 10, 11, 12).
The hepatocytes of the fourth group were not injured with levallorphan, suggesting that levallorphan has no cell toxicity (Fig. 13).
The fifth group showed hepatic cell injury similar to the second group (Fig. 14). Levallorphan thus might have an antagonistic action for the acupuncture effectiveness.
In summary, it was concluded that acupuncture has a protective effect against liver injury caused by carbon tetrachloride administration, and prevents not only animal death but also hepatic cell injury. The mechanism of the acupuncture effectiveness is speculated to be as follows. The stimulus of the acupuncture is conducted to the central nervous system and then the central nervous system secretes some neural hormonal substances such as endorphin or enkephalin, which might regulate or accelerate the autonomic nervous system, and then the viscerae functions are accelerated and thus might repair the injuries or dieseases.
In the above-mentioned experiments, levellorphan may have disturbed the secretion or action of endorphin or enkephalin from the central vervous system, which was said to be secreted following the acupuncture treatments, resulting in the ineffectiveness of acupuncture treatments.

The acupuncture points are quite important in Oriental medicine. They have been known for about 3, 000 years. However, the points have not been ascertained morphologically to date.
In this experiment, the acupuncture points such as Hoku (LI-4), Taichong (LV-3) and one of the auricular points, which were at first obtained morphologically using a Rydoraku point-searching apparatus (12V, DC), and then needled perpendicularly with acupuncture needle No. 30, staining the tip of the needle with carbon black ink to mark the point localizations.
Small pieces of skin were marked with ink cuts and fixed with 10% neutralized formalin, and then serial paraffin sections were made for light microscopical observations.
The acupuncture points seemed to be the places at which the electric resistance was usually lower than at other non-acupuncture points.
Non-acupuncture points with high electric resistance were also taken for the control (Fig. 7).
From the light microscopical observations of the acupuncture points, a special complex was found (Figs. 2, 3, 4, 5, 6). It was composed of a nerve fiber running horizontal to the surface of the skin, some blood and lymph vessels and a small amount of collagenous fibers.
These elements seemed to be a plexus forming a complex, and the complex was usually located within the subcutaneous tissue.
On the other hand, such complex had not been observed at the non-acupuncture points so far (Fig. 7).
In summary, it is postulated that the acupuncture points seem to be in some way related to the nervous elements, the vascular system and collagenous fibers.
