Cancer anorexia-cachexia syndrome is characterized by decreased food intake, weight loss, muscle tissue wasting and psychological distress, and this syndrome is a major source of increased morbidity and mortality in cancer patients. This study aimed to clarify the gut-brain peptides involved in the pathogenesis of the syndrome and determine effective(More)
Yokukansan (YKS), a traditional Japanese medicine, is composed of seven kinds of dried herbs. It is widely prescribed in clinical situation for treating psychiatric disorders such as aggressiveness in patients with dementia. We previously demonstrated that YKS and Uncaria hook (UH), which is a constituent herb of YKS, had a partial agonistic effect to(More)
To clarify the mechanism of yokukansan (TJ-54), a traditional Japanese medicine, against glutamate-mediated excitotoxicity, the effects of TJ-54 on glutamate uptake function were first examined using cultured rat cortical astrocytes. Under thiamine-deficient conditions, the uptake of glutamate into astrocytes, and the levels of proteins and mRNA expressions(More)
PURPOSE To clarify the relative biological effectiveness (RBE) values of various human cell lines for carbon-ion beams with 2 different linear energy transfer (LET) beams and to investigate the relationship between the cell-killing effect and the biophysical characters, such as the chromosome number and the area of the cell nucleus, using qualitatively(More)
Yokukansan, one of the traditional Japanese herbal medicines, ameliorated neuropathic pain symptoms in patients. In this study, we investigated the effects of yokukansan on neuropathic pain in chronic constriction injury (CCI) model. Oral administration of yokukansan significantly inhibited mechanical and cold allodynia in the von Frey hair or acetone test,(More)
The possible preventive effect of Kampo medicine Hange-shashin-to (TJ-14) on chronic diarrheal symptoms induced by the administration of the anticancer agent irinotecan hydrochloride (CPT-11) was investigated in the rat. Repeated oral administrations of TJ-14 at 125 and 500 mg/kg significantly prevented the reduction in body weight and the onset of chronic(More)
The effect of Daikenchuto, a traditional herbal medicine, on gastrointestinal hypoperistalsis in postoperative ileus (POI) was investigated. POI was induced by laparotomy with manipulation of the gastrointestine under anesthesia, and gastrointestinal transit was calculated by migration of Evans blue. Daikenchuto (270 - 2,700 mg/kg, p.o.) dose-dependently(More)
The present study investigated the effect of Daikenchuto (DKT) on postoperative intestinal adhesion in rats. We evaluated the effects of DKT, constituent medical herbs and active compounds on talc-induced intestinal adhesion in rats and DKT-induced contractions using isolated guinea pig ileum. DKT significantly prevented adhesion formation, and this action(More)
To determine the mechanisms by which Hange-shashin-to (TJ-14) reduces prostaglandin E2 (PGE2) levels, the effects on blood corticosterone levels were examined in vivo and the effects on cyclooxygenase (COX) activity in vitro assessed. TJ-14, orally administered to rats at dose levels between 125 and 1000 mg/kg, caused a dose-dependent increase in blood(More)
The present study was conducted to clarify the effects of Dai-kenchu-to on accelerated small intestinal movement. We evaluated the effects of Dai-kenchu-to and its constituent herbs (dried ginger root, ginseng, zanthoxylum fruit, and malt sugar) on carbachol-accelerated mouse small intestinal transit, and contractions induced by low-frequency(More)
