The localization of serotonin-immunoreactivity (5-HT-IR) in the locus ceruleus (LC) of rats was studied by the peroxidase-anti-peroxidase method using a purified antibody obtained from a rabbit. Antibody production was performed according to the method of Grota and Brown (1974). The antibody was applied to serial cryostat sections with alternate(More)
Purified antisera against GABA were prepared. A few small GABAergic neurons in the rat locus coeruleus were immunohistochemically demonstrated by both the unlabeled peroxidase-antiperoxidase method and the avidin-biotin peroxidase complex method using affinity-purified GABA antibodies. The glial fibrillary acidic protein immunoreactivity in this nucleus was(More)
The purpose of this retrospective study was to assess the efficacy of salvage radiation therapy (RT) or chemoradiation therapy (CRT) for locoregional recurrence (LR) of esophageal cancer after curative surgery. Forty-two patients who received salvage RT or CRT for LR of esophageal cancer after curative surgery between November 2000 and May 2012 were(More)
A virus neutralizing test using an indirect immunoperoxidase technique (VNT-IIP) for rabies has been developed for the titration of dog and cat serum samples in Japan. The VNT-IIP has the advantage that results obtained can be viewed by the naked eye. The purpose of this study was to validate the VNT-IIP and compare it with one of the international standard(More)
GABAergic neuronal profiles in the supraoptic nucleus of the rat were immunohistochemically identified by using a purified GABA antibody with the peroxidase-antiperoxidase method. The localization of GABA-like immunoreactivity in nerve terminals on the neurosecretory neurons was examined electron microscopically. A few small GABAergic neurons were found(More)
The aim of this study was to assess the immunomodulatory effect of KC-1317 (a symbiotic mixture containing Saccharomyces boulardii lysate in a cranberry, colostrum-derived lactoferrin, fragaria, and lactose mixture) supplementation in immune-compromised but otherwise healthy elderly subjects. A liquid formulation of KC-1317 was administered in a randomized(More)
Increased intestinal permeability has been advocated as one of the likely causes of various pathologies, such as allergies and metabolic or even cardiovascular disturbances. Thus, the aim of the present study was to test a symbiotic preparation containing microbial lysates (KC-1317, Named, Italy) against stress-induced derangement of gut mucosa(More)
BALB/c mice were divided into young, middle-aged, and aged groups, and each group was given 3 weeks of oral treatments: (1) 1 mL of VBC1-99 (a mixture of 42 fruits and vegetables extracts) or (2) 1 mL of same amount of antioxidant vitamins as control. Steady-state hepatic adenosine triphosphate (ATP) was assessed by phosphorus-31 nuclear magnetic resonance(More)
