Abstract
OBJECTIVES To compare the discriminative capabilities for the manifestation of sarcopenia or physical frailty between serum creatinine- and cystatin C-derived indices among community-dwelling older adults. DESIGN Cross-sectional study. SETTING Primary Care and Community. PARTICIPANTS We utilized a subset of data from the Frail Elderly in the Sasayama-Tamba Area (FESTA) study, which was initiated in 2015 to gather comprehensive information on various health-related parameters among community-dwelling older individuals (age ≥65 years). MEASUREMENTS Five serum creatinine-cystatin C based indices including the Sarcopenia Index, the serum creatinine/cystatin C ratio, the disparity between serum cystatin-C-based and creatinine-based estimated GFR, the total body muscle mass index (TBMM), and the prediction equation for skeletal muscle mass index (pSMI) were employed. Sarcopenia and physical frailty were identified based on the Asian Working Group for Sarcopenia criteria and the revised Japanese version of the Cardiovascular Health Study criteria, respectively. The receiver operating characteristic (ROC) and logistic regression analyses were performed to assess the discriminative abilities of these tools. RESULTS In the analysis of 954 participants, 52 (5.5%) were identified with sarcopenia and 35 (3.7%) with physical frailty. Regarding sarcopenia discrimination, TBMM and pSMI both exhibited area under the curve (AUC) values exceeding 0.8 for both men and women. Concerning the identification of physical frailty, AUC values ranged from 0.61 to 0.77 for males and 0.50 to 0.69 for females. In the multivariate logistic regression analyses, only TBMM and pSMI consistently displayed associations with sarcopenia, irrespective of sex (P<0.001, respectively). On the other hand, no consistent associations were observed between the indices and physical frailty. CONCLUSIONS This study provides a robust association of a serum creatinine- and cystatin C-derived indices, especially TBMM and pSMI, with sarcopenia among community-dwelling older adults. Conversely, the application of these indices for the screening of physical frailty has its constraints, necessitating further investigation.

Abstract
BACKGROUND Functional dyspepsia (FD), a heterogeneous disorder, involves multiple pathogenetic mechanisms. Developing treatments for FD has been challenging. We performed a randomized, placebo-controlled, double-blind clinical trial to determine the efficacy of rikkunshito, a Japanese herbal medicine, in FD patients. METHODS FD patients (n = 192) who met the Rome III criteria without Helicobacter pylori infection, predominant heartburn, and depression were enrolled at 56 hospitals in Japan. After 2 weeks of single-blind placebo treatment, 128 patients with continuous symptoms were randomly assigned to 8 weeks of rikkunshito (n = 64) or placebo (n = 61). The primary efficacy endpoint was global assessment of overall treatment efficacy (OTE). The secondary efficacy endpoints were improvements in upper gastrointestinal symptoms evaluated by the Patient Assessment of Upper Gastrointestinal Disorders-Symptom Severity Index (PAGI-SYM), the Global Overall Symptom scale (GOS), and the modified Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease (m-FSSG), and psychological symptoms evaluated by the Hospital Anxiety and Depression Scale (HADS). KEY RESULTS Rikkunshito increased OTE compared to placebo at 8 weeks (P = .019). Rikkunshito improved upper gastrointestinal symptoms (PAGI-SYM, GOS, and m-FSSG) at 8 weeks, especially postprandial fullness/early satiety (P = .015 and P = .001) and bloating (P = .007 and P = .002) of the PAGI-SYM subscales at 4 weeks and 8 weeks. Improvement of HADS at 8 weeks (P = .027) correlated with those of PAGI-SYM (r = .302, P = .001), GOS (r = .186, P = .044), and m-FSSG (r = .462, P < .001), postprandial fullness/early satiety (r = .226, P = .014), dyspepsia (r = .215, P = .019), and PDS (r = .221, P = .016). CONCLUSION & INFERENCES Rikkunshito may be beneficial for FD patients to simultaneously treat gastrointestinal and psychological symptoms.

Abstract
BACKGROUND Many micro-RNAs (miRNAs) are differentially expressed in Helicobacter pylori-infected gastric mucosa and in gastric cancer tissue and previous reports have suggested the possibility of serum miRNAs as complementary tumour markers. The aim of the study was to investigate serum miRNAs and pepsinogen levels in individuals at high risk for gastric cancer both before and after H. pylori eradication. METHODS Patients with recent history of endoscopic resection for early gastric cancer and the sex- and age-matched controls were enrolled. Serum was collected from subjects before or after eradication and total RNA was extracted to analyse serum levels of 24 miRNAs. Serum pepsinogen (PG) I and II levels were measured using enzyme-linked immunosorbent assay kits. RESULTS Using miR-16 as an endogenous control, the relative levels of miR-106 and let-7d before and after H. pylori eradication and miR-21 after eradication were significantly higher in the high-risk group than in the controls. H. pylori eradication significantly decreased miR-106b levels and increased let-7d only in the control group. After eradication, the combination MiR-106b with miR-21 was superior to serum pepsinogen and the most valuable biomarker for the differentiating high-risk group from controls. CONCLUSION Serum miR-106b and miR-21 may provide a novel and stable marker of increased risk for early gastric cancer after H. pylori eradication.

Abstract
BACKGROUND Improvement in subjective symptoms has been reported in functional dyspepsia (FD) patients administered with acotiamide. Improvement was confirmed in meal-related symptoms, such as postprandial fullness, upper abdominal bloating, and early satiety. We examined the mechanism underlying the effects of acotiamide on gastric accommodation reflex (GAR) and gastroduodenal motility in FD patients. METHODS Thirty-four FD patients (mean age, 40.4 years) were examined ultrasonographically before and after 14-18 days of acotiamide (100 mg t.i.d.) or placebo administration. To assess GAR, expansion rate in cross-sectional area of the proximal stomach was measured after every 100-mL ingestion, using a straw, of up to 400 mL of a liquid meal (consommé soup, 13.1 kcal; 400 mL) in a supine position. Next, we measured gastric emptying rate (GER), motility index (MI, antral contractions), and reflux index (RI, duodenogastric reflux) to assess gastroduodenal motility. Patients also completed a survey based on the seven-point Likert scale both before and after drug administration. KEY RESULTS Of the 37 cases, 19 and 18 were administered with acotiamide and placebo A respectively, significant difference was observed in GAR between the acotiamide and placebo groups (21.7%vs 4.4%) after 400 mL ingestion. GER significantly accelerated after treatment in the acotiamide group (P = 0.012), no significant differences were observed in MI and RI between the two groups. Improvement rates were 35.3 and 11.8% for the acotiamide and placebo groups. CONCLUSIONS & INFERENCES Acotiamide significantly enhances GAR and GER in FD patients. Acotiamide may have therapeutic potential for FD patients.

Abstract
BACKGROUND The mechanisms of the development of symptoms in functional dyspepsia (FD) patients have not been fully elucidated. We previously reported that acid directly infused into the stomach causes dyspeptic symptoms in asymptomatic healthy controls (HCs); however, the response to acid infusion of FD patients was not determined. AIM To investigate the severity of dyspeptic symptoms induced by direct acid infusion in FD subjects and HCs. METHODS This was a multi-centre, cross-over, randomised, double-blind study in 23 FD subjects and 32 HCs. FD was defined using the Rome III criteria. All subjects were Helicobacter pylori negative. Each subject received two tests; 0.1 mol/L hydrochloric acid and water infused into the stomach. The presence and severity of 12 dyspeptic symptoms were assessed using a visual analogue scale. RESULTS The proportion of subjects developing symptoms by acid or water infusion was significantly greater in FD subjects than HCs. All of the FD subjects experienced at least one symptom by water or acid infusion. In the FD subjects, the severity of symptoms was significantly greater with acid infusion than water infusion. The severity of symptoms in total and the scores for eight of the 12 symptoms induced by acid infusion was significantly greater in FD subjects than in HCs. CONCLUSIONS The severity of dyspeptic symptom generation induced by direct acid infusion into the stomach was significantly greater in functional dyspepsia subjects than in healthy controls, suggesting that hypersensitivity to acid is one of the important mechanisms of the development of symptoms in functional dyspepsia patients.

Abstract
Concentrations of serum estradiol-17β and progesterone were monitored in six female walruses using an enzyme immunoassay. Progesterone concentrations increased from March to May in females aged 6 y or older, and subsequently declined (October). No significant elevation of estradiol-17β concentration was detected before an elevation of progesterone concentration. Vaginal smears from four females were examined with Papanicolaou staining. In all females, most epithelial cells were basophilic intermediate-superficial cells; no color change from basophilic to eosinophilic of the cells was detected. Meanwhile, the percentage of anucleate cells in vaginal smears reached its highest value before the elevation of progesterone concentration, followed by an increase in the percentage of leukocytes. We inferred that the change in populations of anucleate cells and leukocytes in vaginal smears reflected ovarian status and CL formation in female walruses.

Abstract
BACKGROUND Impaired vagal function has been reported to be important in some patients with functional dyspepsia (FD). However, the pathophysiologic mechanisms influencing the cephalic phase of vagal activity in FD are incompletely understood. The aim of this study was to investigate the gastric response to modified sham feeding (MSF) on ultrasound and cardiovascular autonomic function in FD patients. METHODS Nineteen patients with postprandial distress syndrome (PDS, 11 men and eight women; mean age: 48.2 years) and 26 healthy subjects (HS, 13 men and 13 women; mean age: 45.0 years) were studied prospectively. Firstly, cardiovascular autonomic function was assessed by spectral analysis of RR interval variability. Antral contraction was then evaluated by ultrasonography after MSF was performed to stimulate the cephalic phase of vagal activity. KEY RESULTS Spectral analysis of RR interval variability showed that the high-frequency component was significantly smaller in the patients than in the HS (P<0.01). The frequency of antral contraction in response to MSF over 15 min was also significantly lower in the PDS patients than in the HS. The 15-min integrated antral contractile response (area under the contraction vs time curve) was significantly smaller in the PDS patients than in the HS (P<0.01). Univariate analysis revealed a modest correlation between the high-frequency component of RR interval variability and the area under the contraction vs time curve (n=46, r=0.49, P<0.01). CONCLUSIONS & INFERENCES Autonomic abnormalities affecting the cephalic phase of vagal activity may be important in the pathogenesis of FD.

Abstract
Fingertip blood flow (FTBF) as measured by laser Doppler flowmetry (LDF) measurement is considered an indicator of sympathetic nerve function. We evaluated autonomic function in patients with irritable bowel syndrome (IBS) by assessing FTBF with both LDF and continuous-wave (cw) Doppler sonography. Firstly, the two methods were compared in 40 healthy volunteers. Next, 59 patients with IBS as well as 118 healthy volunteer controls were studied. In the supine position, FTBF in the right index finger was measured with cw Doppler sonography, whereas FTBF in the left index finger was assessed with LDF. After baseline measurement for at least 5 min, the volunteers received sympathetic stimulation from cold stress applied without notification in the form of an icebag (0 degrees C) upon the left forearm for 1 min. The new cw Doppler sonography method can be used in place of the old LDF method for clinical purposes. FTBF velocity before stimulation (V(pre)) was significantly lower in the IBS group than that in the healthy volunteers (P < 0.01). In addition, the time required for FTBF to return to V(pre) after stimulation was significantly longer in the IBS group than that in the control group. (P = 0.02). Thus, measurement of FTBF with cw Doppler sonography can be useful in the assessment of sympathetic nerve function. The IBS patients showed an abnormal FTBF response suggesting the presence of excess sympathetic activity.

Abstract
OBJECTIVE The relationship between acid and dyspeptic symptoms has not been fully understood. AIM To investigate the type and severity of dyspeptic symptoms induced by direct acid infusion into the stomach of Japanese healthy subjects. METHODS This was a multi-centre, cross-over, randomized, double-blind study in 27 healthy subjects (mean age 27). Each fasted subject received two tests with 150 mL of 0.1 mol/L hydrochloric acid infusion (15 mL/min for 10 min) and the same volume of pure water infusion. The type and severity of symptoms were assessed by a 10 cm visual analogue scale administered every 2 min up to 30 min. RESULTS Various symptoms were reported after both acid and water infusions. Most of the symptoms were more severe after acid infusion compared with water infusion (acid vs. water: discomfort 1.8 +/- 0.4 vs. 0.5 +/- 0.1, pain 0.6 +/- 0.3 vs. 0.1 +/- 0.1, reflux 1.0 +/- 0.3 vs. 0.3 +/- 0.1 and satiety 1.1 +/- 0.4 vs. 0.2 +/- 0.1). The area under curve for dysmotility like symptoms (heavy feeling in the stomach, bloating, nausea or feeling sick, and belching) was significantly higher in acid infusion, and symptoms continued after infusion of the acid. CONCLUSION Acid induced into stomach induced dysmotility-like predominant dyspeptic symptoms in Japanese healthy control subjects, demonstrating the possible importance of acid in symptom generation.

Abstract
BACKGROUND Anti-parietal cell antibody is found in patients with Helicobacter pylori-positive gastritis and is related to atrophic gastritis and gastric carcinoma. AIM To identify the characteristics of patients at high-risk for gastric carcinoma in terms of anti-parietal cell antibody and serum pepsinogen. PATIENTS AND METHODS Subjects were 92 H. pylori-positive patients (54 men, 38 women; mean age, 57.9 years; range, 15-88 years). The serum concentrations of pepsinogen I and II were determined by radioimmunoassay, and the presence of anti-parietal cell antibody was assessed by enzyme-linked immunosorbent assay. Degrees of inflammation and atrophy in the corpus of the stomach were evaluated histologically. RESULTS Patients were classified into four groups according to anti-parietal cell antibody status and pepsinogen I/II ratio. Anti-parietal cell antibody-negative/pepsinogen I/II-low patients had the highest risk for gastric carcinoma (prevalence of gastric carcinoma: 7/13=53.8%, odds ratio=7.6, 95% confidence interval, 1.2-48.0). Anti-parietal cell antibody titre was high when inflammation in the corpus was severe (p=0.06) and significantly low when atrophy in the corpus was severe (p=0.01). CONCLUSION Our results showed that patients with a negative anti-parietal cell antibody titre and low pepsinogen I/II ratio are at high-risk for gastric carcinoma.

Abstract
AIM To investigate the effect of famotidine on gastric blood flow reduction induced by diclofenac sodium, a common non-steroidal anti-inflammatory drug in Japan, using laser Doppler flowmetry in the canine stomach. METHODS The gastric mucosal blood flow was measured by laser Doppler flowmetry in 15 healthy male beagles before and 60 min after the administration of diclofenac suppository (1.0 mg/kg) into the rectum. The examination was done in a crossover, single-blinded fashion. All dogs underwent both famotidine (0.5 mg/kg) and placebo (saline) injection simultaneously with the administration of diclofenac. In addition, the tissue concentration of prostaglandin E2 was measured. RESULTS The blood flow decreased by 18.3 +/- 9.1% in the gastric body, by 26.3 +/- 8.1% in the antrum in the placebo group after the administration of diclofenac sodium, while the decreases seen were significantly smaller in the famotidine group: 3.2 +/- 12.6% in the gastric body and 7.9 +/- 16.5% in the antrum (P = 0.001 for the gastric body, P = 0.0034 for the antrum). Conversely, the percentage of mucosal prostaglandin E2 concentration decrease in each group did not show a significant difference. CONCLUSION Famotidine alleviates the reduction of gastric blood flow induced by diclofenac sodium. Further, not only mucosal prostaglandins but also gastric acid may play an important role in non-steroidal anti-inflammatory drugs-induced gastric microcirculatory disturbance.

Abstract
BACKGROUND Recent studies showed that acid-suppressive therapy aggravates corpus gastritis in patients with Helicobacter pylori infection. AIM The aim of this study was to evaluate the effect of famotidine, a histamine receptor antagonist on corpus gastritis in patients with peptic ulcer disease. METHODS We enrolled 287 patients, 173 with duodenal ulcer and 114 with gastric ulcer and 100 patients with H. pylori-positive gastritis as control subjects. Patients with peptic ulcer were classified according to whether or not they received famotidine-maintenance therapy (20 mg/day) after primary treatment. At the time of endoscopy, biopsy specimens were obtained from the antrum and the corpus. The degrees of neutrophil and lymphocyte infiltration, atrophy and intestinal metaplasia were scored according to the updated Sydney System. RESULTS The degrees of neutrophil infiltration and atrophy in the corpus were significantly less in patients with gastric ulcer or duodenal ulcer than in patients with H. pylori-positive gastritis (P < 0.01). Differences in the degrees of neutrophil infiltration and atrophy in the corpus between the non-maintenance group and the maintenance group were not significant. CONCLUSION Long-term therapy with famotidine does not appear to lead to an increase in the incidence of corpus gastritis or corpus atrophy in patients with peptic ulcer disease.

Abstract
AIM We investigated the effect of acid suppression therapy on recurrent bleeding after successful endoscopic treatment of bleeding peptic ulcer. METHODS A total of 400 patients with bleeding peptic ulcer received either intravenous infusion of famotidine (40 mg/day) (n = 207, 163 males, 44 females, mean age 61.5 years) or drip infusion of omeprazole (40 mg/day; n = 193, 134 males, 59 females, mean age 59.8 years) after successful endoscopic treatment. The fasting duration, hospital stay, volume of transfused blood, incidence of rebleeding and mortality were compared between the two groups. RESULTS The incidence of rebleeding did not differ significantly between the famotidine group (9%) and the omeprazole group (8%). The mean hospital stay was significantly shorter in the omeprazole group (18.4 days) than in the famotidine group (21.5 days, P = 0.009). However, there was no statistically significant difference in fasting duration, volume of transfused blood or mortality. CONCLUSION Our findings indicate that intravenous infusion of famotidine after successful endoscopic treatment is equivalent to drip infusion of omeprazole for prevention of recurrent bleeding.

Abstract
BACKGROUND Eradication of Helicobacter pylori is expected to prevent the development of gastric cancer. However, gastric cancer is sometimes discovered after successful eradication of H. pylori. AIM To conduct a prospective study to determine the clinical features of patients who underwent successful eradication and were later diagnosed with gastric cancer. METHODS A total of 1787 patients (1299 males and 488 females; mean age, 58.2 years; range: 15-84) who underwent successful eradication therapy between April 1994 and March 2001 were our study subjects. RESULTS Gastric cancer occurred at a rate of 1.1% (20 of 1787) during the follow-up period. Gastric cancer comprises six of 105 (5.7%) with early gastric cancer after endoscopic resection, 12 of 575 (2.1%) with gastric ulcer and two of 453 (0.4%) with atrophic gastritis. Gastric cancer did not develop in any patient with duodenal ulcer. All patients with gastric cancer had baseline severe atrophic gastritis in the corpus. CONCLUSION Careful endoscopic examination is necessary even after successful eradication of H. pylori in patients with early gastric cancer or gastric ulcer with severe mucosal atrophy in the corpus.

Abstract
BACKGROUND Eradication of Helicobacter pylori improves clinical symptoms and quality of life in patients with peptic ulcer. AIM To investigate the effect of eradication of H. pylori on body mass index and incidence of hyperlipidaemia in patients with peptic ulcer. PATIENTS AND METHODS The study population comprised 50 patients (42 men, 8 women; mean age, 51 years; 28 gastric ulcer, 22 duodenal ulcer) who underwent physical and blood examination before and 1 year after undergoing eradication therapy and 100 sex- and age-matched control subjects. Body mass index, total cholesterol and triglyceride were measured before and 1 year after therapy. RESULTS The eradication therapy group showed a significant increase in body mass index (22.7+/-2.5 kg/m2 before eradication versus 23.6+/-2.6 kg/m2 after eradication, p < 0.01), serum total cholesterol (204.1+/-33.2 mg/dL versus 221.2+/-38.8 mg/dL, p < 0.01), and triglyceride. Additionally, the eradication therapy group showed a significant increase in the incidence of hypercholesterolemia (30% versus 58%, p<0.01), hypertriglyceridaemia (28% versus 44%, p < 0.01) and obesity (12% versus 22%, p <0.05) 12 months after therapy. CONCLUSION Our findings show that eradication of H. pylori significantly increases the incidence of hyperlipidaemia and obesity in patients with peptic ulcer.

Abstract
AIM To investigate whether curing Helicobacter pylori infection improves symptoms over the long-term in Japanese patients with nonulcer dyspepsia and fundic atrophic gastritis. METHODS Ninety H. pylori-positive dyspeptic patients with fundic atrophic gastritis were enrolled in this study. We performed a randomized double-blind placebo-controlled trial comparing triple therapy (n=45) with that of placebo alone (n=45). Inflammation and mucosal atrophy were scored according to the Updated Sydney System. Symptoms were scored on a scale of 0 to 3 for six items. Fasting samples of gastric juice were taken before endoscopy, and gastric pH was determined. Serum gastrin and pepsinogen levels were measured, and body mass index was determined. These patients were followed up for 3 years, and all measures were evaluated both before and after therapy. RESULTS Significant improvement in dyspeptic symptoms and gastritis scores, significant decrease in gastric pH, and significant increase in body mass index were found after 3 years eradication in nonulcer dyspepsia patients treated successfully for H. pylori infection. There were no significant changes in the placebo group. CONCLUSION Our study shows that eradicating of H. pylori results in significant long-term reduction in symptoms of nonulcer dyspepsia with fundic atrophic gastritis.

Abstract
BACKGROUND As a non-invasive modality by which to evaluate the gastric emptying of a solid meal, the 13C-octanoic acid breath test has recently become more widely used. Previously, we reported that ultrasonography was another non-invasive and reliable method for assessing gastric motility. The aim of this study was to compare the reliability of these two methods. METHODS Seventeen patients with functional dyspepsia and 10 healthy volunteers were studied. The solid test meal consisted of a scrambled egg labeled with 13C-octanoic acid (100 mg) and served with a bowl of rice and boiled chicken (total 424 kcal). After ingestion of the test meal, all subjects were examined in the sitting position. Ultrasonography images were obtained every 15 min for 3 h. Breath sampling followed the same time schedule as for the ultrasonography, with an additional 3 h of sampling at 30-min intervals. We investigated the half emptying time (T1/2) and the lag phase with both methods. RESULTS The T1/2 by the ultrasonography method and the breath test were positively correlated (r2 = 0.638); however, there was no significant agreement between the study groups. Both the T1/2 and the lag phase were prolonged in the functional dyspepsia patients compared with the healthy volunteers, regardless of the method of measurement. The lag phase was significantly correlated (r2=0.864) with the T1/2 by the breath test. CONCLUSIONS Although the 13C-octanoic acid breath test cannot assess the gastric emptying of solids as reliably as ultrasonography, both tests are useful for evaluating functional dyspepsia patients with delayed gastric emptying.

Abstract
BACKGROUND Although there are several established methods used to evaluate esophageal motility, none allows for direct observation of esophageal wall motion. Esophageal dysmotility is thought to contribute to reflux esophagitis (RE). The aim of this study was to evaluate esophageal wall motility by endosonography using a miniature ultrasonographic probe (MUP) in patients with RE. METHODS The subjects consisted of 10 healthy controls (10 men with a mean age of 31.5 years) and 9 patients with RE (4 men and 5 women with a mean age of 51.5 years). High-frequency endoluminal sonography was performed using a 20-MHz transducer through a 16F gastric tube to evaluate esophageal wall motion. Four sonographic phases of an esophageal peristaltic sequence were identified. In the resting phase, the esophageal wall was in direct contact with the transducer. In the passive distention phase, the esophageal lumen was stretched maximally; in the contraction phase, it contracted; and in the relaxation phase, it returned to baseline. The baseline thickness of the muscle layers of the esophageal wall was measured at rest. The width decreased during the passive distention phase, increased and reached a maximum during the contraction phase, and returned to baseline during the relaxation phase. RESULTS The contractility index of the circular smooth muscle (CSM) in the distal esophagus and of the longitudinal smooth muscle (LSM) in the proximal esophagus were significantly lower in patients with RE. The duration of contraction in the distal esophagus was significantly longer in RE. CONCLUSIONS We used a MUP to demonstrate abnormalities in esophageal wall motility in patients with RE. We conclude that the MUP is a potentially useful technique for evaluating esophageal dysmotility.

Abstract
In 3 adult female cheetahs, induced-superovulation treatment was conducted, by means of 200 IU of pregnant mare serum gonadotropin (PMSG) and 100 IU of human chorionic gonadotropin (hCG) 80 hr after PMSG. The administration of PMSG created a sharp increase in the estradiol-17beta concentration, resulting in 232 pg/ml 8 hr later in one specimen out of three. The hCG administration showed an increase in the progesterone concentration of 2.29 ng/ml 46 hr later. In addition, after direct observation of the ovary surface by laparoscopy, 5 follicles in the right ovary over 2 mm in diameter, and 7 corpora lutea (5 in the right ovary and 2 in the left) were found. It is assumed that ovulation can be induced with hCG after 80 hr on PMSG during a cheetah's diestrus or proestrus.

Abstract
A new advanced glycation end product (AGE), N(omega)-carboxymethyl-arginine (CMA), was found in acid-soluble skin collagen of a newborn bovine prepared by in vitro glycation with 1 M glucose incubation at 37 degrees C for about 30 days [ 1 ]. CMA production was increased with incubation time in parallel, and after 30 days incubation the yield was 100 times higher than that of pentosidine [ 1 ]. This result suggested the importance of CMA as a major AGE in collagen. We have detected and measured the CMA level in human serum proteins by electrospray ionization/liquid chromatography/mass spectrometry (ESI/LC/MS), using CMA standard concentration curve. In this report, we first show the existence of CMA in vivo, and its serum level is significantly elevated in diabetic serum proteins, compared to age-matched control serum proteins. These results provide strong evidence that CMA is a new diagnostic marker of glycation in diabetes.

Abstract
We report a case of basal subarachnoid hemorrhage in a child. The etiology of this lesion was difficult to diagnose. The patient was a 9-year-old boy. He sustained minor head injury followed by loss of consciousness and cardiopulmonary arrest. He was brought to our emergency room by ambulance. On arrival, he presented with cardiopulmonary arrest and deep comatose state. Basal subarachnoid hemorrhage was revealed on CAT scan. 3D-CTA documented two bulging portions: one was at the junction between the left vertebral artery and the left posterior inferior cerebellar artery. The other one was shown at the basilar artery. He died on the 7th hospital day. The autopsy revealed a laceration of the left vertebral artery. Microscopically, the wall around the laceration showed a defect in the internal elastic membrane and a decrease of smooth muscle cells with moderate fibrosis in the tunica media. These findings were compatible with the structure of a congenital aneurysm. Hence, the patient was strongly suspected to have had a congenital aneurysm whose rupture was triggered by minor head injury.

Abstract
BACKGROUND Duodenogastric reflux has been implicated in the pathogenesis of gastric ulcer and gastritis. Duodenogastric reflux after cholecystectomy is also a possible cause of post-cholecystectomy syndrome. AIM To investigate the role of antroduodenal motor function in increased duodenogastric reflux following cholecystectomy and the effect of trimebutine maleate (trimebutine) on the duodenogastric reflux in conscious dogs. METHODS Antropyloric and duodenal motility and bile acids content in the gastric juice were measured for 3 h during the inter-digestive state in dogs with or without cholecystectomy. RESULTS Bile acids content in the gastric juice of cholecystectomized dogs was significantly higher than that of non-cholecystectomized dogs. The frequency of pyloric relaxation during phase II of the migrating motor complex was significantly increased following cholecystectomy. Intravenous infusion of trimebutine inhibited both the increased duodenogastric reflux and the frequency of pyloric relaxation in the cholecystectomized dog. CONCLUSION Duodenogastric reflux and frequency of pyloric relaxations were increased in cholecystectomized dogs and trimebutine suppressed both of them. These findings suggest that the increased frequency of pyloric relaxation contributes to the duodenogastric reflux following cholecystectomy.

Abstract
Although it is important to assess gastrointestinal blood flow, no generally useful, noninvasive assessment method has been established. Harmonic flash echo imaging, which is an intermittent second harmonic imaging technique, has recently become available to evaluate blood flow. We investigated the usefulness of harmonic flash echo imaging in the assessment of the gastrointestinal tract, and we used this technique to study the effect of nicotine on small bowel blood flow. Harmonic flash echo imaging was performed at the beginning of intravenous injection of a contrast agent. It was also performed on the small bowel immediately before and 10 min after nicotine administration to evaluate blood flow. Gastric and small bowel walls were clearly enhanced on the primary images. Small bowel enhancement, which is regarded as transmural blood flow, significantly decreased after nicotine administration. Harmonic flash echo imaging appears to be useful in the assessment of the transmural blood flow in the gastrointestinal wall.

Abstract
To detect low concentrations of enterohaemorrhagic Escherichia coli O157:H7 rapidly, flow cytometry (FCM) was carried out with specific IgG-sensitized latex beads (IgG-Lx). It was found that test samples for FCM can be prepared for much shorter periods by culturing E. coli O157:H7 in trypto-soya broth at 42 degrees C and by treatment with 0.5% formalin at 37 degrees C. FCM with IgG-Lx performed with E. coli O157:H7 prepared by such a procedure revealed that the lowest number of E. coli O157:H7 prepared in pure culture detected by FCM was 10(3)/ml. Because similar findings have already been reported by FCM with immunomagnetic beads, FCM with IgG-Lx is also suggested to be a valuable technique to detect low numbers of E. coli O157:H7 rapidly in food stuffs.

Abstract
BACKGROUND AND AIMS Although antroduodenal motility has usually been studied by using manometric or scintigraphic methods, ultrasonography is an established, non-invasive method to evaluate duodenogastric motility. We used ultrasonography to evaluate gastric motility in patients with functional dyspepsia. METHODS Sixty-four patients with functional dyspepsia and 36 asymptomatic healthy subjects were given liquid and solid test meals. We investigated the gastric emptying rate, motility index, and duodenogastric reflux for the liquid meal and gastric emptying time, half-emptying time, and motility index for the solid meal. RESULTS After the liquid meal, the gastric emptying rate and motility index were significantly lower and the duodenogastric reflux was significantly higher in functional dyspepsia patients than in healthy subjects. After the solid meal, gastric emptying time, half-emptying time and the motility index were significantly lower in the patients than in the healthy subjects. Delayed gastric emptying of both meals occurred in only 20.3% of patients. Delayed emptying of the liquid or solid meal occurred in 62.5% of patients. In both groups, gastric emptying time of the solid meal was positively correlated with the motility index at 15 min post-ingestion. CONCLUSION In functional dyspepsia patients, delayed gastric emptying of a solid meal was related to antral hypomotility during the early postprandial phase. Ultrasonographic assessment of gastric motility in both liquid and solid meals may provide a better understanding of the pathogenesis of functional dyspepsia.

Abstract
Development of gamma irradiation preservation of ready-to-eat, commercially prepared fish cutlet and improvement of microbiological quality were studied. Studies on the shelf life extension by a combination of irradiation and ascorbic acid treatments of fish cutlets prepared at the laboratory and commercial scale have also been conducted. Cutlets prepared at the laboratory scale according to selected formulation and irradiated at a dose of 5 kGy could extend the shelf life up to 5 weeks at room temperature. In commercially prepared fish cutlets, maximum shelf life extension observed was 14 days for samples treated with 5 kGy of irradiation and stored at ambient temperature on the basis of combined microbiological, chemical, and organoleptic evaluation. The microbiological quality of the commercially prepared fish cutlets revealed the unhygienic conditions of the place where the fish was prepared and the unhygienic storage conditions and temperatures. As a result, the chemical and irradiation treatments were not effective in extending the shelf life of the cutlets under the storage condition used in this study compared with that of the laboratory scale-prepared cutlets.

Abstract
Formation of advanced glycation end products (AGEs) is accelerated in diabetic subjects along with hyperglycemia. Although several lines of evidence indicate that AGEs stimulate macrophages to secrete several cytokines and growth factors, little is known about the effect of AGEs on the primary function of macrophages, such as phagocytosis. On the other hand, impairment of the phagocytic function of monocytes/macrophages is suggested to contribute to the low resistance to infection in diabetic subjects. In the present study, we examined the effect of AGEs on the phagocytic function of macrophages. Using flow cytometric analysis of mouse resident peritoneal macrophages, we showed that AGEs suppress phagocytosis of fluorescent microspheres by cultured macrophages. In addition, experiments using streptozotocin-induced diabetic mice demonstrated a significant decrease in the phagocytic activity of resident peritoneal macrophages 12 weeks after induction of diabetes compared with age-matched control mice. The phagocytic activity of peritoneal macrophages correlated inversely with AGE content in the adjacent peritoneal tissue. Furthermore, reduced phagocytic activity of macrophages was associated with a reduction in intracellular ATP content. Because phagocytosis is an important component of the defense system, suppression of such activity by AGEs may explain, at least in part, the increased susceptibility of diabetic patients to infection.

Abstract
Medulloblastoma usually originates in the cerebellum. We report here a case of medulloblastoma originating in the pons. Pontine medulloblastoma is extremely rare, with only one report in the literature. An 11-year-old girl was admitted to our hospital with vertigo. Magnetic resonance imaging (MRI) revealed a tumor originating in the pons. On the 4th day after admission, the tumor bled. Because the patient's life was in danger from brain herniation, hematoma removal and tumor resection were carried out. The diagnosis was medulloblastoma. After surgery, the patient received radiation therapy and chemotherapy. Unlike tumors originating in the cerebellum, this tumor did not seem to be effectively reduced by these therapies. Radiation therapy and chemotherapy may not be effective for medulloblastoma originating in the pons. We considered it necessary to make a histological diagnosis even though the tumor originated in the pons and resection was difficult technically.

Abstract
The inhibitory effect of calcinated calcium on the growth of Escherichia coli O157:H7 during fresh radish (Raphanus sativus L.) sprout production was studied. It was revealed that the addition of 0.4% (wt/vol) calcinated calcium into radish sprouting medium which was artificially contaminated with E. coli O157:H7 (3.0 to 3.2 log CFU/ml) completely inhibited the growth or inactivated the microorganism. When radish seed extract was used instead of radish sprout production, the same extent of growth inhibition or inactivation was observed with much lower amounts (0.07%) of calcinated calcium under similar experimental conditions. The findings suggested that calcinated calcium may be useful to control E. coli O157:H7 contamination during the production of radish sprouts.

Abstract
BACKGROUND Recent studies have shown that the eradication of Helicobacter pylori results in a gastric acid secretion which decreases to normal levels in patients with duodenal ulcer disease. The aim of this study was to evaluate the effect of eradication of H. pylori in a 24-h study of gastric acidity in patients with atrophic gastritis of the corpus. METHODS Intragastric acidity was measured by continuous 24-h pH monitoring, and the histology of the gastric antrum and corpus were evaluated in 14 H. pylori-positive patients with histologically proven atrophic gastritis of the corpus (10 men, 4 women; mean age, 57 years) before and 1 year after anti-H. pylori therapy. RESULTS H. pylori was absent in 13 of 14 patients 1 year after treatment. Both gastritis and atrophy scores were significantly lower after eradication therapy (P < 0.01). The 24-h median pH and the percentage of 24-h pH readings above 4.0 units were significantly decreased after eradication therapy (from 5.12 +/- 0.36 to 2.69 +/- 0.21, and from 65.5 +/- 6.6% to 28.2 +/- 6.1%, P < 0.01, respectively.) CONCLUSION Eradication of H. pylori increases 24-h gastric acidity in patients with atrophic gastritis of the corpus. Improvement of the histology of the gastric antrum and corpus may lead to the normalization of gastric acidity.
