After the release of huge amounts of radionuclides into the ocean from the devastated Fukushima Dai-ichi Nuclear Power Plant (FDNPP), safety concerns have arisen for marine products in Fukushima Prefecture. As of October 2012, we had inspected the radionuclide ((131)I, (134)Cs and (137)Cs) concentrations in 6462 specimens within 169 marine species collected(More)
The present immunohistochemical study reveals that a small number of chromaffin cells in the rat adrenal medulla exhibit CGRP-like immunoreactivity. All CGRP-immunoreactive cells were found to be chromaffin cells without noradrenaline fluorescence; from combined immunohistochemistry and fluorescence histochemistry we suggest that these are adrenaline cells.(More)
Immunohistochemical examination for neuronspecific enolase (NSE), neurofilament protein (NFP), and S-100 protein was performed in the olfactory mucosa of human fetuses. NSE and NFP immunoreactivities were found in the olfactory receptor cells, while no S-100 immunoreactive cells were recognized within the olfactory epithelium. The anti-NSE serum stained(More)
The pancreatic islets of the dog, guinea pig and pigeon were studied under the electron microscope and the following results were obtained. 1. Besides A and B cells, D cells are constantly found in the islets of these three species. The D cell granules, when fixed in glutaraldehyde especially by perfusion, are represented by a solid substance of medium(More)
AbstractIn order to clarify the clinical and genetic features of SCA6, we retrospectively analyzed 140 patients. We observed an inverse correlation between the age of onset and the length of the expanded allele, and also between the age of onset and the sum of CAG repeats in the normal and the expanded alleles. The ages of onset of four homozygous patients(More)
This study in the guinea pig demonstrated that ulcerative colitis-like lesions were induced more rapidly and effectively than in other laboratory animals by the oral administration of dextran sulfate sodium (DSS). In all guinea pigs receiving 3% DSS solution, diarrhea was noted within 48 h, and bleeding at 48–72 h. Light microscopically, hemorrhagic and(More)
Immunohistochemistry by use of an antiserum against neurofilament protein (NFP) was applied for staining nerve fibers in the predentin and dentin of human third molars. By devising methods for fixation, decalcification and immunostaining, nerve fibers were clearly and specifically demonstrated in thick (more than 50 μm) sections of teeth. Numerous(More)
The distribution of calcitonin gene-related peptide-immunoreactive nerve fibers in the renal pelvis and ureter was examined by immunohistochemistry using whole-mount preparations and cryostat sections. The patterns of innervation were contrasted between the pelvis and ureter; the immunoreactive nerve fibers in the pelvis ran parallel to the long axis of(More)
Adrenal glands of human fetuses were investigated by means of an immunohistochemical method with the use of an anti-S-100 serum. S-100-immunoreactivity was recognized in sustentacular cells located among the chromaffin cells. A characteristic circular arrangement of the immunostained cells was found in the central region of the adrenal glands. It surrounded(More)
The present study deals with the localization and development of S-100 protein-like immunoreactivity in the retina, ciliary body and iris of human fetuses. In the retina, numerous astrocytes, densely distributed in the nerve-fiber layer and ganglion-cell layer, were stained strongly with the S-100 antiserum. The first immunoreactive astrocytes occurred at(More)
