The structure of the ear, which intervenes between gross anatomy and histology in size, can be best understood by means of three-dimensional (3D) surface models on a computer. Furthermore, surface models are the source of interactive simulation for clinical trials, such as tympanoplasty. The objective of this research was to elaborate the surface models of(More)
Microinjection of formalin (5%, 50 microl) into a temporomandibular joint (TMJ) causes noxious behavioral responses in freely moving rats. In the present study, we investigated the role of central cyclooxygenase (COX) pathways in IL-1beta-induced hyperalgesia with formalin-induced TMJ pain model. Intra-articular injection of 100 pg or 1 ng of IL-1beta(More)
UNLABELLED The present study investigated the role of central metabotropic glutamate receptors (mGluRs) in interleukin-1beta (IL-1beta)-induced mechanical allodynia and mirror-image mechanical allodynia in the orofacial area. Experiments were carried out on male Sprague-Dawley rats weighing 230 to 280 g. After administration of 0.01, 0.1, 1, or 10 pg of(More)
PURPOSE Sectioned images of cadavers enable creation of realistic three-dimensional (3D) models. In order to build a 3D model of a structure, the structure has to be outlined in the sectioned images. The outlining process is time consuming; therefore, users want to be provided with outlined images. The more detailed structures are outlined, the greater(More)
The interpretation of computed tomographs (CTs) and magnetic resonance images (MRIs) to diagnose clinical conditions requires basic knowledge of sectional anatomy. Sectional anatomy has traditionally been taught using sectioned cadavers, atlases, and/or computer software. The computer software commonly used for this subject is practical and efficient for(More)
Sectional anatomy of human brain is useful to examine the diseased brain as well as normal brain. However, intracerebral reference points for the axial, sagittal, and coronal planes of brain have not been standardized in anatomical sections or radiological images. We made 2,343 serially-sectioned images of a cadaver head with 0.1 mm intervals, 0.1 mm pixel(More)
Authors had prepared the high-quality sectioned images of a cadaver head. For the delineation of each cerebral gyrus, three-dimensional model of the same brain was required. The purpose of this study was to develop the segmentation protocol of cerebral gyri by referring to the three-dimensional model on the personal computer. From the 114 sectioned images(More)
In medicine, the neuroanatomy of the oculomotor (III), trochlear (IV), and abducens nerves (VI) is learned essentially by cadaver dissection, histological specimens, and MRI. However, these methods have many limitations and it is necessary to compensate for the insufficiencies of previous methods. The aim of this research was to present sectioned images and(More)
The objective of this research was to produce high-quality sectioned images of a whole dog which can be used to create sectional anatomy atlases and three-dimensional (3D) models. A year old female beagle was sacrificed by potassium chloride injection and frozen. The frozen dog was then serially ground using a cryomacrotome. Sectioned surfaces were(More)
In our previous research, we created state-of-the-art sectioned images, color-coded images, and surface models of the human ear. Our ear data would be more beneficial and informative if they were more easily accessible. Therefore, the purpose of this study was to distribute the browsing software and the PDF file in which ear images are to be readily(More)
