We have been utilized acupuncture and moxibustion in our department of internal medicine at Meiji University of Integrative Medicine since its investment in 1987. In the department, various kinds of symptoms in the field of internal medicine have been managed with acupuncture and moxibustion. In this article, I would like to introduce our activities regarding acupuncture treatment in the department of internal medicine and some remarkable results of our clinical studies which evaluated effects of acupuncture and moxibustion as well as relationship between acupuncture therapists and the staff of our department. In the field of respiratory disorders such as COPD or bronchial asthma, usefulness of acupuncture have been proved through a controlled clinical trial which involved COPD patients who had not been able to control with standard care. Also, acupuncture was found to be useful in the management of bronchial asthma in a case series study in which acupuncture treatment was repeatedly applied with intervals without acupuncture. We have also demonstrated that acupuncture was useful for gastrointestinal disorders such as irritable bowel syndrome (IBS). Results of a case series with n-of-1 study design showed significant reduction in the symptoms during acupuncture treatment, while those in the period without acupuncture had been aggravated. Data from studies on diabetic complications such as peripheral neuropathy or gastropathy also showed usefulness of acupuncture. We considered that it is valuable to explore unknown usefulness of acupuncture in the field of internal medicine and prove effectiveness of acupuncture with appropriate scientific manner.

Background
Although there are several reports that electroacupuncture (EA) in the abdomen reduces fasting blood glucose and improves insulin sensitivity, the effects under a glucose load or hyperinsulinemic conditions have not yet been studied. In this study, we investigated the effect of EA at Zhongwan (CV12) under the conditions of an intravenous glucose tolerance test (IVGTT) and a hyperinsulinemic euglycemic clamp in normal Sprague-Dawlay (SD) rats.
Methods
Male SD rats were anesthetized with pentobarbital (40mg/kg i. p.) and then maintained by continuous infusion through a tail vein. Blood samples were drawn from the ventral tail artery during the fasting stage (baseline and 30min after), and at 2, 5, 10, 20, 30, 45, 60min after a glucose load (0.5g/kg). EA was performed for 30min (EA30, n=8) during the fasting stage and for 90min (EA90, n=8) during both the fasting and IVGTT periods. In the hyperinsulinemic euglycemic clamp experiments, insulin (2mU/kg/min) was infused through the tail vein, followed by infusion of 20% glucose at variable rates to maintain fasting blood glucose levels. EA was performed for 40min after a steady-state was achieved.
Results
Significant decreases in fasting blood glucose and increase in plasma insulin concentration were observed during the fasting period in rats in both the EA30 and EA90 groups, whereas rats in the control group (n=8) which did not receive any EA stimulation showed no such changes. Total glucose levels during the IVGTT were lower in the EA30 and EA90 groups compared to controls, with a significantly higher level of relative insulin secretion. During the hyperinsulinemic euglycemic clamp, glucose consumption was increased significantly by EA stimulation with a marked increase in both insulin concentration and sensitivity.
Conclusion
EA at CV12 accelerates glucose consumption during IVGTT and hyperinsulinemic conditions probably as a consequence of increased insulin sensitivity and/or increased plasma insulin concentration.

[Objective] It is necessary to administer anti-cholinergic agents or glucagon during gastroscopy for inhibition of gastric peristalsis. However, application of these drugs are limited in patients with glaucoma, hypertension, benign prostate hyperplasia, heart disease, or diabetes mellitus because of possible adverse events.
Based on the report that acupuncture stimulation at CV 12 (Zhonguan, Chukan) inhibited gastric activity, we studied whether the acupuncture at CV 12 could be applicable as an alternative to these drugs.
[Method] Subjects in the present study were 60 patients who underwent gastroscopy at Meiji University of Oriental Medicine Hospital. They were allocated into two groups; acupuncture group (mean [SD] age, 66 [10]) and drug group (mean [SD] age, 64 [13])
Patients in the acupuncture group were given manual stimulation at CV 12 with an acupuncture needle for 10 minutes before examination and during gastroscopy.
After examination, a gastroscopist evaluated the magnitude of the peristalsis and disturbance during the examination using the visual analogue scale (VAS) and a 4-grade categorical scale.
Patients in the drug group were pre-administered anti-cholinergic drug or glucagon, and evaluated with the same scale.
[Results and Discussion] Inhibition score in the acupuncture group was lower but not statistically significant, as compared with the drug group, and the effect of acupuncture stimulation was acceptable to allow examination of the patients without severe disturbance.
Acupuncture may be a useful non-pharmacologic alternative to anti-cholinergic drugs and glucagon to inhibit gastric movement during gastroscopy, when these drugs could not be administered.

To investigate the effect of electro-acupuncture stimulation (EAS) on insulin sensitivity in rats, we performed several stimulations on Otsuka Long Evans Tokushima Fatty (OLETF) rats, during euglycemic clamp. We divided OLETF rats into five groups according to the kind of the stimulation: EAS at vagal innervated region of the auricle (AVA), EAS at non-vagal innervated region of the auricle (ANVA), EAS on the back of the body (AB), pinching on the back of the body (PB), and no stimulation on the body (NS). These procedures were also applied on Long Evans Tokushima Otsuka (LETO) rats as a control study.
Furthermore, we performed long-term stimulation (from six to 24 weeks of age) on OLETF rats to assess the preventive effect of those stimulations on the formation of the insulin resistance. EAS of pulse duration 300ms, 1.5V, 1Hz was applied for 10 or 15minutes. As a result, the glucose infusion rate (GIR) showed significantly higher levels during stimulation of PB group in LETO rats. On the other hand, the GIR of AVA group in LETO rats and PB group in OLETF rats were decreased by stimulation. The GIR in AVA group and AB group after long-term stimulation were significantly higher than those of NS group in OLETF rats. These results suggested that EAS at the auricle and the back is useful for the prevention of the formation of insulin resistance when it's applied before onset of the symptoms in OLETF rats.

Chronic obstructive pulmonary disease (COPD) causes severe respiratory dysfunction and severely limits patients' daily activities. We report a case of the patient with COPD whose respiratory symptoms were successfully improved by acupuncture. A 70-year-old man visited Meiji University of Oriental Medicine Hospital complaining of dyspnea during exercise on _??_. Despite strictly controlled medication and a regimen of home oxygen therapy (HOT), his general condition continued to worsen. Then a series of acupuncture treatment was started on _??_. The severity of dyspnea of the patient before acupuncture treatment was determined as level V according to Hugh-Jones classification, and spirometry showed severely disturbed respiratory functions (%VC: 63.5%, FEV₁%: 29.4%, PEFR: 84.8 1/min in the morning and 93.5 1/min at night). The basic combination of meridian points for the treatment of the case was LU1 (Zhongfu), CV12 (Zhongwan), CV4 (Guanyuan), LU5 (Chize), and BL13 (Feishu). The acupuncture needles were retained for ten minutes in each session. The single-subject research design (A-B-A method) was applied to detect the specific effect of the acupuncture treatment on the respiratory functions or the symptoms of the subject. “A” and “B” mean “treatment period” and “no treatment period” respectively. After 60 acupuncture treatments during a 14-month period, both the respiratory symptoms and the VAS for dyspnea showed improvement, which were specifically observed during the intervention period. Improvement was also reflected in the level of the Hugh-Jones classification and respiratory function test. It was suggested that acupuncture treatment might be effective for advanced cases of COPD.

INTRODUCTION:Acupuncture has been reported to be useful for both physical and psychological symptoms. Here we report a case who complained of various physical symptoms due to advanced hepatocellular carcinoma effectively cared for with acupuncture.
Case:A 64-year-old female complained of general fatigue, constipation, and pain in the lower back and leg during her hospitalization for leg edema due to advanced hepatocellular carcinoma. Although the leg edema was improved by the administration of albumin, physical symptoms such as pain in the lower back and leg, constipation, or general fatigue remained.
We applied acupuncture with aiming at relaxing muscles (erector spinae, rectus femoris, right adductor) by a local needling approach, and to improve incomplete defecation by applying moxibustion at the acupoint on the abdomen.
METHOD:Faces Scale was used to evaluate general condition. Evaluation of the pain in the lower back and lower extremities were made with a Numerical Scale where 10 indicates the most painful, while 0 indicates no pain.
RESULT:Both general fatigue and pain in the lower extremities wererelieved after acupuncture treatments (FS for general condition improved from 3to 1, NS for pain decreased from 7 to 4). Also, the feeling of incomplete defecation disappeared.

The present study investigated the effect of moxibustion for 4 weeks on insulin resistance in Otsuka-Long-Evans Tokushima Fatty (OLETF) rats, a model of spontaneous noninsulin-dependent diabetes mellitus (NIDDM). Glucose infusion rate (GIR) in the moxibustion group was higher than that in the control group. This finding suggests that moxibustion may be effective for insulin resistance.

We report the succesful treatment for improvement of orthostatic hypotension of a case of Shy-Drager syndrome (SDS).
CASE REPORT
A 56 year-old man diagnosed with SDS was admitted to our hospital on July 8, 1988 because of orthostatic hypotension. He had been suffering from dizziness, dysuria and muscular rigidity for 2 years. He had been treated with drug-therapy, but these sympton had progressed. Physical examination on admission revealed severe orthostatic hypotension due to disorders of autonomic nervous system, so he could not stand still.
For the treatment, we performed Yushi and punctured its points (Geshu. Hachiyu, Danshu, Pishu, Weishu) or 3 points (Sanyinjiao, Taixi, Taichong) that is located on legs. Acupuncuture therapy was applied from July 13, 1988 to December 10, 1988, every day except on holiday. We estimated the effect of acupuncture therapy with transition of blood pressure and orthostatic hypotension. Transition of acupuncture therapy were as follows.
(1) Yushi were performed alone.
(2) 3 points of legs (Sanyinjiao, Taixi, Taichong) were punctured alone.
(3) Yushi were performed, and 3 points of legs were punctured.
(4) Geshu, Genshu, Pishu and 3 points of legs were punctured.
(5) Subcutaneous needle at Yushi points.
(6) Punctured depth of 1cm to Yushi points.
Symptomatical respons was observed at about 70th treatment, and blood pressure was stabilized constantly and activity of daily life was improved.
Kinoshita et al. reported that Yushi act to sympathetic nervous system inhibitory, so serve to treat for hypertension. But in this case, its act was accelerate. It is speculated that Yushi act to autonomic nervous system homeostatically.
