INTRODUCTION
There have been very few reports on the effects of acupuncture on abnormal eye movements often seen in patients with central vertigo. Recently we had the opportunity to apply acupuncture to a case of Wallenberg's syndrome, which displays a peculiar nystagmus and vertigo. This case is reported because the effectiveness of acupuncture in improving the eye movement was proved by the electronystagmography (ENG) in collaboration with the Nihon University School of Medicine.
CASE REPORT
Patient: A 47 year old man. Diagnosis: Wallenberg's syndrome. Chief Complaint: Vertigo. Present Illness: In Nov. 1980, the patient noticed a loss of pain and temperature sense in his right limb, followed by vertigo. He was admitted to the Nihon Univ. Hospital in Dec. 1980. CT-examination of the whole body, a vertebral arteriogram, etc. indicated a circulatory failure in the left lateral area of the medulla oblongata.
In Mar. 1981, the patient visited our clinic with the chief complaint of vertigo. Present Condition: He complained of rotary vertigo. The orthostatic test was positive with both opened and closed eyes. A decrease in the pain and temperature sense on the right side of the body, except for the head, was observed.
COURSE
Acupuncture was applied to the posterior region of the neck, the back, and the lateral of the lower extremity in order to relax the muscles of these parts. After acupuncture the patient reported a decrease in his vertigo. After the twentieth session of acupuncture the symptoms improved to the extent that he could go out alone. After the twenty-second session, he returned to work. Although his vertigo and nystagmus did not completely disappear, an obvious improvement in these symptoms was seen after each session, and this improved condition remained for two or three days. With the ENG recorded before, shortly after, and 30min. after a session of acupuncture therapy, a decrease in abnormal eye movement after the session was confirmed.
CONCLUSION
Acupuncture therapy was applied to a case of Wallenberg's syndrome.
Result:
1. A short-term decrease in vertigo was observed.
2. A decrease in abnormal eye movement after acupuncture therapy was confirmed by electronystagmography.

Many patients who receive general acupuncture treatment have many complaints concerning their autonomic nervous systems. Applying CMI and CMI type classification (Abe method-a variation of CMI) to 100 new patients who came to our clinic last year, we found vegetative dystonia in half of them. Upon this finding, the following examinations were carried out by means of an function test of autonomic nervous system developed by Kageyama et al.: the coefficient of variation (CV) of R-R interval in ECG obtained through the function test is regarded as an expression of vagal function.
(1) Using this test, the participation of the autonomic nervous system in the condition of those patients who visited our clinic was examined.
(2) Effects of acupuncture treatment on the autonomic nervous system were examined.
(3) Acupuncture stimulation was separately applied to S36 (Zusanli), P4 (Ximen) and Liv3 (Taichong) to examine the influence of the acupuncture point location on the CV obtained through the test.
Results:
(1) 15 new patients (25%-comparatively high rate) showed low CV (less than 2%) of R-R interval in ECG.
(2) In some cases, acupuncture treatment caused an increase in CV.
(3) Acupuncture caused pulse infrequens: R-R interval showed a tendency toward prolongation during the in situ needle technique and after withdrawing the needle on each of the three points (S36, P4 and Liv3). CV increased after withdrawing the needle on either S36 or Liv3 and shortly after needle insertion and after withdrawing the needle on P4.
These result suggest that many patients who receive acupuncture treatment have additional disorder in parasympathetic nervous system which can be improved through acupuncture.

On Ishigaki Island, Plasmodium falciparum and Plasmodium vivax epidemics occurred in 1945-1946 and were successfully suppressed. The epidemic re-emerged in 1949 because many settlers immigrated to the former endemic areas, but it terminated in 1961. The present study aimed at predicting an outbreak of a new epidemic based on the situation in which P. falciparum malaria patients stay on Ishigaki Island and also examined the re-emergence of the P. falciparum epidemic in 1951-1960 to determine the reliability of the model.
A stochastic transmission model of P. falciparum was constructed to detect a small number of infected persons. The seasonal fluctuation of the Anopheles minimus population obtained by observational data and meteorological data through statistical processing was introduced into the model.
Simulations were carried out to predict the risk of a new epidemic with scenarios in which the attribute of index patient, visiting season, and reduced inoculation rates of An. minimus were assumed. When an infected person visited the island in summer, a small number of patients with primary infections derived from the index patient appeared for all 1,000-iterations. On the other hand, when an infected person visited the island in winter, few or no patients with primary infections appeared for any of the 1,000-iterations because of the low mosquito density. In realistic conditions, the simulation results showed that there was little possibility of the occurrence of P. falciparum infection.

The muscle fibers of M. rectus abdominis from 3 sportsmen (Weight-lifting, Boxing and Body-building) were examined histologically and compared with the mean of 22 human control subjects. Following results were obtained.
1. Compared with the M, rectus abdominis of control subjects, the sportsmen's rectus abdominis muscle area was about 4 times the cross-sectional area of muscle belly and the number of muscle fibers per sq, mm, were 1/3 that of the control specimens. The total number and mean size of sportsmen muscle fibers corresponded to the respective maxima of the controls, and the muscle fiber density in sportsmen corresponded to the minimum control value.
2. Comparing the myofibrous organization of 3 specimens, the muscle of the boxer was largest in cross-sectional area, in frequency of muscle fibers with large diameter, and in volume of interstitial connective tissue. It was the smallest of the 3 specimens in the number of muscle fibers per sq. mm. We found that the muscle of the weight-lifter was intermediate in these four categories.

A mathematical model for transmission of schistosomes is useful to predict effects of various control measures on suppression of these parasites. This review focuses on epidemiological and environmental factors in Schistosoma japonicum and Schistosoma mekongi infections and recent advances in mathematical models of Schistosoma transmission.

Up until the present, the primary treatment for threatened premature labor has been bed rest, with drug therapy as a supplement. However, with drug therapy the problems of side effects and dosage limitations have made it difficult to achieve therapeutic effectiveness. In this paper, the authors report the favorable results obtained in such cases when moxibustion and a microwave emitter were used for stimulation therapy based on Oriental medical theory. Moxibustion was carried out on Shim, Yusen and Saninko (acupuncture points) in cases of threatened premature labor beyond the 24th week. Despite the short duration of treatment, uterine tension was relieved, fetal movement increased, and resistance in the umbilical artery and uterine artery reduced. Similar results were achieved with multiple microwave stimulation treatments; the effects lasted for long periods and were not accompanied by side effects. Thus, the results showed that through the use of moxibustion therapy in conjunction with drug therapy, the dosage could be reduced, and the frequency of side-effect appearance lowered. These results suggest that moxibustion therapy has potential as an effective and safe new treatment for threatened premature labor.

We reviewed 632 cases which had undergone ultrasonograpy for thyroid disorders.(1) The sonographic examination found nodular lesions in 157 cases (including 52 solid tumor cases) and diffuse enlargement in 38 cases. No abnormalities were found in the remaining437 cases.(2) Further examination revealed that the cases of nodular lesions included 7 thyroid cancer cases (6 papillary carcinomas and 1 follicular carcinoma), 2 cases of hyperthyroidism, and 3 cases of hypothyroidism.(3) Diffuse enlargement cases included 5 cases of overactive thyroid (1 subacute thyroiditis and 5 Graves' diseases), 2 cases of underactive thyroid (chronic thyroiditis). Assays for antithyroid autoantibodies showed positive results even in the 31 cases of normal thyroid function.(4) Four in 7 cases diagnosed as thyroid cancer and 5 in 12 cases diagnosed as thyroid dysfunction (4 of 5 cases were elderly people 60 years of age or over) were screened by ultrasonography.
We concluded that ultrasonography is a valuable diagnostic procedure for early detection of not only thyroid malignancies but also disordered thyroid function. Abdominal sonography is often used for screening. The use of ultrasound for the thyroid gland is recommended as a standard procedure in the regular health screening program.

We describe two cases of a 9-day-old male and a 5-year-10-month-old female who had congestive heart failure due to severe mitral regurgitation. Preoperative echocardiogram revealed severe mitral regurgitation due to dysplasia of the leaflet, chordae and papillary muscle. Because the leaflet area was not enough for the valve orifice, we performed double orifice repair by suturing the free edge to the corresponding edge of the opposite leaflet. The mitral regurgitation was found to be significantly reduced on postoperative echocardiogram. Double orifice repair is simple and can be performed rapidly. However, although this technique has been performed in adults, it has not been commonly performed in infants. Our results suggest that this procedure can be useful for the congenital mitral regurgitation. Long-term follow-up is needed to confirm the result.

Objective : To evaluate the effect of heat and steam generating sheets on osteoarthritis of the knee. Methods : Subjects with osteoarthritis of the knee (n=41) were randomized into 2 groups : a heat and steam generating sheet group or a heat generating sheet group. Functional impairment [Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Japan Orthopaedic Association score (JOA score)] in the index knee were measured at baseline and then again after 2 and 4 weeks of wear. Results : At both the 2 and 4 week patient evaluations, the heat and steam generating sheet group showed improved total WOMAC scores. Although the heat generating sheet groups' WOMAC scores were improved after 2 weeks, the difference between the 2 and 4 week evaluations was not statistically significant. As for individual WOMAC scores, patients in the heat and steam generating sheet group especially demonstrated a highly significant decrease in WOMAC stiffness score. In comparison, patients in the heat generating sheet group showed no improvement in WOMAC stiffness score. Gait ability improvement, as measured by JOA score, showed similar results for both groups. Conclusion : This study showed that using heat and steam generating sheets decreased pain and stiffness, and increased gait ability in patients with osteoarthritis of the knee.

[Objective] Physical exercises raise more or less body temperature. A body temperature is regulated constantly generally by homeostasis mechanism. Perspiration is only heat radiation mechanism under high temperature environments. And sudoriferous water is supplied from blood. Blood flow is determined by blood fluidity, blood volume and the cardiovascular system. It was reported that strong stress decreased blood fluidity.In this experiment, we investigated the relation between blood fluidity and water supply in rats loaded with forced exercise in high temperature environment.[Methods] SPF male Wistar rats weighing 150 g were used. All animals were put in high temperature environment (Wet Bulb Globe Temperature; WBGT: 28°C) through whole experimental period. In a group of water supply, distilled water was served before and later exercise by sonde forcibly. The rats were divided into five groups randomly; Rest-Non water intake (RN), Rest-Water intake (RW), Exercise-Non water intake (EN), Exercise-Water intake (EW) and Baseline (B). The blood was collected before or later of exercise and blood fluidity or platelet aggregation was measured.[Results] In the EN, platelet aggregation, lactic acid and corticosterone increased while blood fluidity were decreased significantly compared with the RN, RW and EW. In addition, the hematocrit did not increase even if water equivalent to 8 % of body weight lost it.[Conclusion] We speculate that exercise in high temperature environment decreases blood fluidity. However, the water supply that does not completely make up for quantity of depletion in exercise may improve blood fluidity.
