Background/Aims:
Several studies have assessed the effect of cool temperature on colonic peristalsis. Transient receptor potential melastatin 8 (TRPM8) is a temperature-sensitive ion channel activated by mild cooling expressed in the colon. We examined the antispasmodic effect of cool temperature on colonic peristalsis in a prospective, randomized, single-blind trial and based on the video imaging and intraluminal pressure of the proximal colon in rats and TRPM8-deficient mice.
Methods:
In the clinical trial, we randomly assigned a total of 94 patients scheduled to undergo colonoscopy to 2 groups: the mildly cool water (n = 47) and control (n = 47) groups. We used 20 mL of 15°C water for the mildly cool water. The primary outcome was the proportion of subjects with improved peristalsis after treatment. In the rodent proximal colon, we evaluated the intraluminal pressure and performed video imaging of the rodent proximal colon with cool water administration into the colonic lumen. Clinical trial registry website (Trial No. UMIN-CTR; UMIN000030725).
Results:
In the randomized controlled trial, after treatment, the proportion of subjects with no peristalsis with cool water was significantly higher than that in the placebo group (44.7% vs 23.4%; P < 0.05). In the rodent colon model, cool temperature water was associated with a significant decrease in colonic peristalsis through its suppression of the ratio of peak frequency (P < 0.05). Cool temperaturetreated TRPM8-deficient mice did not show a reduction in colonic peristalsis compared with wild-type mice.
Conclusion
For the first time, this study demonstrates that cool temperature-dependent suppression of colonic peristalsis may be associated with TRPM8 activation.

PURPOSE: We conducted a prospective single-center study to evaluate the possibility of discontinuation of dutasteride after combination therapy with an alpha blocker for benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: We prospectively treated BPH patients with an alpha blocker and dutasteride (0.5 mg/d). Patients who had been treated with alpha blockers against BPH for more than 2 months were eligible, and 20 patients were included in the study. After 6 months of combination therapy, dutasteride was discontinued. Patients were followed for 12 months after cessation. Prostate volume, intraprostatic architecture determined by transrectal ultrasound, peak urinary flow rate, postvoid residual urine volume, and the serum prostate-specific antigen level were evaluated every 6 months, and the International Prostate Symptom Score and overactive bladder symptom score (OABSS) every 3 months. Patients were allowed to restart dutasteride during the follow-up period according to their desire. RESULTS: Twelve patients (12/20, 60%) restarted the combination therapy from 6 to 12 months into the follow-up period. For patients who restarted dutasteride, the prostate volume and OABSS had increased and worsened after discontinuation, respectively. A visible transition zone with a clear border on transrectal ultrasound at baseline and regrowth of the prostate after discontinuation of dutasteride were risk factors for restarting the therapy (Mann-Whitney U test: p=0.008, p=0.017). CONCLUSIONS: Prostatic enlargement after discontinuation of dutasteride differs among patients. Rapid regrowth of the prostate leads to deterioration of storage symptoms and a tendency to restart dutasteride. Baseline intraprostatic architecture may be a predictive factor for whether the patient is a good candidate for discontinuation.

We studied contemporary indication of daikankyoto and daikankyoganryo. We administered either of these Kampo prescriptions for thirty-three patients with intractable muscle stiffness of neck, shoulder and back.Twenty-four patients were able to take the prescriptions for more than four weeks (long term group), and nine patients stopped taking the prescriptions less than four weeks (interrupted group). In long term group, fourteen patients (58%) improved their chief compliant. The Kampo formulations of fourteen effective cases were daikankyoto (13 cases) and daikankyoganryo (1 case). Comparative analysis has been done between long term group and nine cases of interrupted group. The characteristics of long term group were higher body mass index, firmer abdomen and more positive cases of epigastric resistance sign. Kansui root dose was 0.81 gram a day in long term group and 0.57 gram a day in interrupted group, which showed statistically-significant difference. We found twenty-seven side-effects in twenty four patients (73%) including eighteen patients with nausea and six patients with diarrhea. In side effects, there was no statistically significant difference between two groups. These side effects were promptly improved after discontinuation or dose reduction of Kansui root. We report clinical courses of six improved cases in this paper, two severe stiff neck, shoulder and back cases, each one case of psychosomatic disorder, depression, spasmodic torticollis and gastroesophageal reflux. These prescriptions should be administered more commonly to the patients with severe stiff neck, shoulder and back.

Shoyogan is a Kampo prescription described in the Junqui Yaolue. Few cases have been reported using this medicine. This time, we prescribed shoyogan for 14 patients who suffered from severe appetite loss. We had positive outcomes as follows. We administered shoyogan to 8 patients with malignant disease. Six of them suffered from lung cancer. Shoyogan was effective in these patients. Shoyogan was not effective for the other 2 patients, with bile duct carcinoma and malignant lymphoma. The dietary intake was increased from 28 percent of meals supplied to 79 percent in the appetite-improved group. We also administered shoyogan to 6 patients with nonmalignant disease. It was effective for 3 patients: 1 with congestive heart failure and 2 with great trochanteric fractures of the femur. It was not effective for the other 3 patients, who suffered from anorexia, pneumonia and depression associated with diabetes mellitus. Shoyogan seems to be effective for patients with terminal lung cancer and maintains their quality of life.

We surveyed side effect incidences with Kampo therapies in 2530 patients based on their Kampo diagnoses. The number of side effects seen, including taste disorder, was 569 in 503 patients. Side effects were noted in 64 (3.0%) of 2139 patients administered Glycyrrhizae radix. The average 63.4±13.8 age of these patients was statistically higher than the overall 54.9±18.1 year mean. Symptoms which led to diagnosis of side effects were high blood pressure in 45 patients, edema in 16 patients, and hypokalemia in only 5 patients. Glycyrrhizae radix dose as an extract was 2.0±1.0 (mean±SD) g/day in 34 patients, and as a decoction was 2.2±1.1 g/day in 29 patients. There was no difference in administration or recovery periods between these two groups. Liver dysfunction was noted in 13 (1.0%) of 1328 patients administered prescriptions containing Scutellaria radix. Scutellaria radix was administered as an extract at 2.3±0.5 g/day in 7 patients, and as a decoction at 2.8±0.8 g/day in 6 patients. Although there was no difference in administration periods, the 69.0±52.5 day recovery period from side effects in the extract group was longer than that of 22.7±16.0 days in the decoction group. Symptom improvement was had for a large portion of these side effects with the first visit, indicating that initial diagnoses were correct. Care should be exercised with regard to inducing side effects, with Kampo medicines, even when using traditional diagnostic standards.

We administered daikenchuto to the patients having recurrent aspiration pneumonia with tube feeding, who had good responses. Case 1 : A 94-year-old-man with congestive heart failure suffering from recurrent aspiration pneumonia even after percutaneous endoscopic gastrostomy (PEG) placement : following daikenchuto administration, he did not suffer from pneumonia, and his general condition became stable. Case 2 : An 80-year-old-man suffering from severe pneumonia after PEG placement, and experiencing recurrent pneumonias after treatment with antibiotics:following daikenchuto administration, we did not find gastric contents in his oral cavity as before, and his general condition became stable. Case 3 : An 85-year-old-man with congestive heart failure and cerebral infarction also suffering from aspiration pneumonia : a nasogastric tube was placed, but he suffered from recurring pneumonias with tube feeding. After administering daikenchuto, he did not suffer from pneumonia and was discharged from the hospital. Case 4 : An 81-year-old-man with recurrent pneumonia and congestive heart failure : after treatment with antibiotics, we placed a PEG tube because of his severe anorexia caused by oral feeding difficulties. In order to prevent aspiration pneumonia, we administered daikenchuto prophylactically. He subsequently developed very little fever until his discharge to a nursing home.

Shoyogan is a Kampo prescription described in the Jinkuiyaolue text, but there have been no case reports regarding this medicine. We report a patient with terminal stage lung cancer, whose appetite and general well-being was maintained following oral administration of this medicine.A 62-year old woman had her main tumor in the left pulmonary lobe, which invaded to the bilateral peritoneum and the mediastinum. Metastasis was recognized in the left femoral bone which had been broken, the ilium, chest and lumbar vertebral bones, and the liver. Her general condition was very poor in spite of the administration of corticosteroids and narcotic medicines, when she began to take shoyogan 5 months after the onset of her symptoms. Cytological examination of her pleural effusion revealed adenocarcinoma. Following the administration of shoyogan, her appetite recovered, nutrition improved, and she was able to survive while maintaining her quality of life for another 2 months.In this paper we discuss the efficacy of shoyogan in improving the general well-being of patients having the above-mentioned conditions, or jueyinbing in Kampo parlance. Although preparing shoyogan is laborious, we believe this medicine should be used more frequently.

Academic dissertations on Kampo medicine have a certain peculiarity about them, when they are drawn up by the rules of western medical writing. Compared to western medicine, oriental medicine tends to employ more subjective terms, because of its many humanistic elements.Study objectives, methods, results and discussions however, need to be stated objectively in a way that makes a paper easy to understand for both referees and readers. Although it would be ideal to use designated terms when making objective statements, there are in fact many terms that have multiple meanings, which need to be clarified in a paper. And when presenting new evidence, one must declare how far any problems have been resolved, as clearly as possible.We have explained the recent changes to our regulations for contributors, regarding Kampo formulae naming conventions, abstract word counts, and contributions by mail. Here we discuss how our editing work proceeds, and our thoughts on how papers are re-reviewed or rejected.
