Gastric inverted hyperplastic polyp (IHP) is a rare type of gastric polyp, and is characterized by downward growth of the hyperplastic mucosal components into the submucosa. To the best ofour knowledge, 16 gastric IHP cases have been described in the English literature, but the pathogenesis has not been established. We report the clinical and pathological(More)
Topoisomerase-II alpha (Topo-II alpha) is known as a cell cycle-related intranuclear marker. To the best of our knowledge, the expression of Topo-II alpha on extranuclear sites has not been reported. The aim of the present study was to determine the usefulness of Topo-II alpha immunostaining for detecting the lipoblasts that are essential to diagnosing(More)
Horvath et al. called relatively small ACTH-immunoreactive (ACTH-IR) cells observed in basophil invasion "proopiomelanocortin (POMC) cells," and these cells were supposed to be different from larger ACTH-IR cells in human adenohypophysis. To clarify the existence of "anterior POMC cells," we examined 21 autopsy cases taking note of follicular cells (FCs).(More)

BACKGROUND The purpose of this study is to report our clinical outcomes using intensity-modulated radiation therapy (IMRT) for adjuvant treatment of cervical cancer, compared with three-dimensional conformal radiation therapy (3DCRT), in terms of tumor control, complications and dose-volume histogram (DVH) parameters. METHODS Between March 2008 and(More)
In our hospital, a clinical trial on the effects of preoperative 2-week S-1 administration for advanced gastric cancer is being conducted. A7 5-year-old man presented to our hospital with a type 2 tumor(poorly differentiated adenocarcinoma)in the pyloric antrum. Subpyloric lymph node enlargement and a c-T2(MP), N1, M0, Stage II A tumor (according to the(More)
The physiological and pharmacological properties of gamma-aminobutyric acid (GABA)-induced responses were investigated in acutely isolated spiral ganglion cells (SGCs) of guinea pig by using either a nystatin-perforated patch recording configuration or a conventional whole-cell patch recording mode combined with rapid drug application. GABA and GABA(A)(More)
