Sensory afferent neurons in the gastrointestinal mucosa regulate neuropeptides [calcitonin gene-related peptide (CGRP), substance P, etc.], which play various physiologic roles and are gastroprotective. To determine whether the pharmacologic effects of Dai-kenchu-to (DKCT) on the gastrointestine are due to changes in gastrointestinal mucosa regulatory(More)
Dai-kenchu-to has been used for the treatment of abdominal obstructions, including bowel obstructions and a feeling of coldness in the abdomen. We reported that Dai-kenchu-to increases plasma neuropeptide [motilin, vasoactive intestinal polypeptide (VIP), serotonin, calcitonin gene-related peptide (CGRP), and substance P]-like immunoreactive substances (IS)(More)
Rikkunshi-to, a gastrointestinal function regulatory traditional Chinese herbal (Kampo) medicine, has recently been evaluated for its clinical usefulness in stress and depression. This medicine has modulatory effects on the hypothalamo-pituitary-adrenal axis and autonomic nervous function. We examined the effect of Rikkunshi-to and the other(More)
Some traditional Chinese herbal (Kampo) medicines have recently been evaluated for their clinical usefulness in stress and depression. These medicines have modulatory effects on the hypothalamic-pituitary-adrenal axis and sympathetic nervous system (SNS). We examined the effects of Rikkunshi-to, Hange-shashin-to, Hange-koboku-to, and Ninjin-to on plasma(More)
We examined the effects of the histamine H2-receptor antagonist, lafutidine, on the levels of gastrointestinal peptides (somatostatin, calcitonin gene-related peptide (CGRP), gastrin, secretin, and motilin) in plasma from healthy subjects. After a single oral administration of lafutidine (10 mg), the plasma lafutidine level (186 +/- 13.4ng/ml) was highest(More)
Hange-shashin-to has been used for chronic hypofunction of the gastrointestinal tract and to improve functional abnormalities of the upper and lower gastrointestinal system. To determine whether the pharmacological effects of Hange-shashin-to are due to gut-regulatory peptide levels, we developed a sensitive and specific double-antibody enzyme immunoassay(More)
The effect of mosapride citrate (mosapride) on plasma levels of gastrointestinal peptides (motilin, gastrin, somatostatin, and secretin) was studied in five healthy volunteers. After a single oral administration of mosapride (15 mg), the plasma mosapride level (85.0+/-13.7 ng/ml) was highest in the 60-min sample after the administration and then the plasma(More)
Regarding the gastroprotective function as a neural emergency system, sensory afferent neurons in the gastrointestinal mucosa regulate neuropeptide (calcitonin gene-related peptide (CGRP), substance P, etc.) levels, and those peptides play various physiological roles. To determine whether the pharmacological effects of Hange-shashin-to and Rikkunshi-to on(More)
Itopride hydrochloride (itopride), a gastrokinetic drug, has recently been evaluated for its clinical usefulness in functional dyspepsia. We investigated effects of itopride on human plasma gastrin-, somatostatin-, motilin-, and cholecystokinin (CCK)-like immunoreactive substances (IS); adrenocorticotropic hormone (ACTH)-immunoreactive substances (IS), and(More)
BACKGROUND Therapeutic drug monitoring (TDM) of voriconazole is important to optimize efficacy and to minimize toxicity and intolerance. In this study, we evaluated the effect of sustained high plasma trough concentration of voriconazole on the incidence of hepatotoxicity in hospitalized Japanese patients. METHODS Thirty-nine patients were divided into 3(More)
