To clarify methodological issues in clinical research involving acupuncture, a randomized controlled trial was performed on subjects complaing of neck stiffness. Thirty-two volunteers who gave informed consent were randomly alloca-ted into experimental and control groups by the envelope method. In the experimental group, the acupuncture needle was inserted to a depth of 20 mm and the swallow-pecking technique was repeated 5 times. In the control group, the acupuncture needle penetrated the skin and was removed immediately. Bilateral Tianzhu points (BL 10) were used in both groups. Acupuncture treatment was performed once a week for 3 sessions and the effect was evaluated by the subjective intensity of stiffness using a visual analogue scale. In both groups subjective evaluation was immediately reduced by acupuncture treatment and the effects tended to persist for 7 days.There was significant difference between the two groups. Methodological issues listed below were discussed for further to promote clinical research on acupuncture. 1) acupuncture points and stimulation conditions, 2) adequate control groups, 3) entry criteria, 4) volunteer bias, 5) masking technique, 6) sample numbers

[Introduction]Insomnia and anxiety are major symptoms of depression and severely limit the daily activities of depressed patients. We report the case of a depressed patient who had developed liver dysfunction caused by medication and whose depression was successfully managed by acupuncture after discontinuation of antidepressants.
[Case]A 37 years-old male had been taking noradrenergic and specific serotonergic antidepressant (NaSSA) and Chai Fu Jia Long Gu Mu Li Tang Jia Wei Gui pi Tang for insomnia and anxiety due to depression. Although his symptoms had improved by the medication, abnormalities in his liver functions were found after 3months of medication. After he was diagnosed as having drug-induced liver damage, he was admitted to Meiji University's Integrative Medicine Hospital and all medication was replaced by Glycyrrhizin and Glutathione. Consequently his depression and symptoms returned. We then tried to relieve his symptoms by applying acupuncture, which was prescribed according to traditional Chinese medical diagnosis (TCM diagnosis, Heart Yin Deficiency , Liver Qi Stagnation , and Kidney Yin Deficiency ).
[Results]After 4 acupuncture treatments, the patient's duration and depth of sleep considerably improved compared with that before the acupuncture sessions, and comparable results were maintained until discharge. Beck Depression Inventory (BDI) scores were also markedly improved from 'moderate depression'(24 points) at the beginning of treatment to 'minimal depression'(8 points) at the end (9th treatment, 16 days from the first session).
[Conclusion]The results of this case suggest that acupuncture treatment may be an effective alternative for anti-depressants when there is a limitation to administer those drugs.

BACKGROUND/AIMS: Esophagogastric junctional lesions, such as mucosal breaks with Los Angeles grade A or B reflux esophagitis, lacerations in Mallory Weiss syndrome, and short segment Barrett's esophagus, are mainly found in the right anterior wall of the distal esophagus. Asymmetrical lower esophageal sphincter pressure and resting radial asymmetrical acid reflux may be causes of this asymmetrical distribution of reflux esophagitis and short segment Barrett's esophagus. We developed a novel pH and pressure catheter to investigate the asymmetrical distributions of pH and intra-esophageal pressure in the distal esophagus. METHODS: One healthy male volunteer was enrolled in this study. Acid reflux and motor function in distal esophagus was investigated using simultaneous measurements of intra-esophageal pH and pressure in 8 directions with novel sensor catheter. RESULTS: Thirty-six acid and weak acid reflux events were observed, of which 22 were circumferential refluxes with pH drops in all channels and 14 were partial refluxes with pH drops in some channels. Increase in transient circumferential intraesophageal pressure was observed just after 72.7% of the circumferential reflux and 42.9% of the partial reflux events. CONCLUSIONS: Using a novel sensor catheter, 2 different types of acid reflux events were identified in the present study.

BACKGROUND/AIMS: The sensitivity of the upper and lower esophageal mucosa to acid is considered to differ. We investigated the relationship between pH changes in different sites of the esophagus and generation of gastroesophageal reflux symptoms during an acid infusion test. METHODS: An acid infusion catheter was placed at 5 or 15 cm above the lower esophageal sphincter (LES) in 18 healthy volunteers, while a 2-channel pH sensor catheter was also placed in each with the sensors set at 5 and 15 cm above the LES. Solutions containing water and hydrochloric acid at different concentrations were infused through the infusion catheter. RESULTS: Acid infusion in the upper esophagus caused a pH drop in both upper and lower esophageal sites, whereas that in the lower esophagus resulted in a significant pH drop only in the lower without a corresponding pH decline in the upper esophagus. Stronger heartburn, chest pain, and chest oppression symptoms were noted when acid was infused in the upper as compared to the lower esophagus, while increased intra-esophageal acidity strengthened each symptom. Regurgitations caused by upper and lower esophageal acid infusions were similar, and not worsened by a larger drop in intra-esophageal pH. Chest pain was caused only by lowered intra-esophageal pH, while heartburn, chest oppression, and regurgitation were induced by a less acidic solution. CONCLUSIONS: Higher intra-esophageal acidity caused stronger heartburn, chest pain, and chest oppression symptoms. However, regurgitation was not significantly influenced by intra-esophageal acidity. The upper esophagus showed higher acid sensitivity than the lower esophagus.

BACKGROUND/AIMS: Rikkunshito (TJ-43), an herbal medicine, has been demonstrated to relieve gastroesophageal reflux symptoms. However, the effects of TJ-43 on esophageal motor functions have not been fully determined. This double-blind crossover study was performed to investigate the effects of TJ-43 on esophageal motor functions and gastroesophageal reflux. METHODS: The subjects were 10 normal male volunteers. Lower esophageal sphincter pressure and esophageal body peristaltic contractions with and without 1-week administration of TJ-43 were examined in a crossover fashion. Post-prandial gastroesophageal reflux was also determined using a multi-channel impedance pH dual monitor. RESULTS: TJ-43 at a standard dose of 7.5 g/day did not significantly augment esophageal peristaltic contraction pressure measured in the proximal, middle and distal segments of the esophagus, whereas increment of resting lower esophageal sphincter pressure was observed in a supine position. In addition, TJ-43 administration did not decrease post-prandial gastroesophageal acid, non-acid reflux events or accelerate esophageal clearance time. CONCLUSIONS: TJ-43 at a standard dose did not have a significant effect on esophageal motor activity or gastroesophageal reflux in healthy adults.

BACKGROUND/AIMS: In Japan, it is customary to take a daily bath during which the body is immersed in water to the neck. During full-body immersion, hydrostatic pressure is thought to compress the chest and abdomen, which might influence esophageal motor function and intra-gastric pressure. However, whether water immersion has a significant influence on esophageal motor function or intragastric pressure has not been shown. The aim of this study was to clarify the influence of full-body water immersion on esophageal motor function and intragastric pressure. METHODS: Nine healthy male volunteers (mean age 40.1 +/- 2.8 years) were enrolled in this study. Esophageal motor function and intragastric pressure were investigated using a high-resolution 36-channel manometry device. RESULTS: All subjects completed the study protocol. Intragastric pressure increased significantly from 4.2 +/- 1.1 to 20.6 +/- 1.4 mmHg with full-body water immersion, while the lower esophageal high pressure zone (LEHPZ) value also increased from 20.5 +/- 2.2 to 40.4 +/- 3.6 mmHg, with the latter being observed regardless of dietary condition. In addition, peak esophageal peristaltic pressure was higher when immersed as compared to standing out of water. CONCLUSIONS: Esophageal motor function and intragastric pressure were altered by full-body water immersion. Furthermore, the pressure gradient between LEHPZ and intragastric pressures was maintained at a high level, and esophageal peristaltic pressure was elevated with immersion.
