    Notes: Henneguya pagri n. sp. (Myxozoa: Myxosporea) is described from netpen-cultured red sea bream, Pagrus major, in Japan. Affected fish displayed anaemic gills, an enlarged bulbus arteriosus and internal haemorrhaging in the pericardial cavity. Disease outbreaks occurred during the summer and the prevalence of infection reached 75% in August. Plasmodia of H. pagri developed in the bulbus arteriosus of red sea bream, in which degenerative cardiomyopathy was observed. Following maturation of the parasite, the influx of spores into the gills caused congestion of the gill capillaries, resulting in proliferative branchitis. Spores (10.5 × 7.5 μm) were ovoid with two caudal appendages (29.6 μm in average length), with a whip-like extension from the end. Partial small subunit ribosomal RNA gene sequences of H. pagri are closely related to those of H. lateolabracis infecting the bulbus arteriosus of Chinese sea bass, Lateolabrax sp.

    Notes: 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.

    Clinical features of gastric cancer discovered after successful eradication of 〈fr〉Helicobacter pylori〈/fr〉: results from a 9-year prospective follow-up study in Japan (2005)

    Notes: 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.

    Morphological changes in human gastric tumours after eradication therapy of Helicobacter pylori in a short-term follow-up (2005)

    Notes: Background : It is controversial as to whether the development of gastric cancer is influenced by Helicobacter pylori eradication. If eradication itself influences the tumour morphology, this may affect the tumour discovery rate.Aim : To investigate the morphological changes in the gastric neoplasm after H. pylori eradication.Methods : We studied 37 patients with eradication therapy. After a 1-month follow-up, endoscopic re-evaluation was performed and the appearance was compared with first image. All lesions were resected endoscopically, and were subjected to histological assessment and to immunohistochemistry. Serum gastrin levels were determined before and after eradication.Results : Twenty-nine of 37 patients underwent successful eradication. The appearance of 11 lesions (33% of 33 lesions) became indistinct after successful eradication. All lesions were of the superficial-elevated type and the height of the lesions decreased. We detected normal columnar epithelium over the neoplasm in eight of the lesions. Higher expression of single-stranded deoxyribonucleic acid in the deep area was characteristic in tumours with an indistinct appearance. These changes did not correlate with the serum gastrin levels.Conclusions : The morphology of the gastric neoplasm change after eradication in the short-term. This may contribute to the decreased tumour discovery rate.

    Notes: The tension-tension fatigue tests for SiC/SiC composites were performed under theconditions that the maximum load Pmax was 80-90% to the fracture load of the tensile tests and thestress ratio was Rσ = 0.5. The composites exhibited a width in stress-strain hysteresis loop underone load cycling. In some cases the mean strain εmean gradually increase with increasing in numberof cycles. These variations would reflect the developments of the fatigue damage at the fiber/matrixinterface during the cyclic loading process. The pull-out lengths of the fibers for the fatigued- andnot fatigued-specimens were measured through the SEM observations after the tensile test. In allmaterials, the average pull-out length of fibers in fatigued material was larger than in not fatiguedmaterial because the cyclic loading affected on the fiber/matrix interfacial strength
