The temporal changes in intensity of myelination of the nervous pathways in 0 to 42-day-old Wistar rats were quantitatively analyzed by immunohistochemistry with anti-proteolipid protein and compared with that obtained by immunohistochemistry with anti-myelin basic protein. Immunohistochemistry was performed on paraffin-embedded tissue according to the(More)
Adult male crickets (Gryllus bimaculatus) show a nocturnal circadian locomotor rhythm, which is driven by the pacemaker in the optic lamina-medulla complex and synchronizes to the light-dark (LD) cycle received by the compound eye. To see whether there was any specially differentiated circadian photoreceptor area in the eye, we examined the effect of a(More)
It is well known that tumor angiogenesis plays an important role in local growth and metastasis of oral cancer; therefore, inhibiting angiogenesis is considered to be effective for treating oral cancer. This study aimed to investigate the effectiveness of systemically available antiangiogenic gene therapy targeting vascular endothelial growth factor (VEGF),(More)
Cervical lymph node (CLN) metastasis from oral cancer correlates with poor prognosis. Therefore, accurate assessment of CLN status is crucial in treatment planning. However, there are few reports focusing on CLN metastasis from tongue cancer. Further, the growth and progress of the tumor are known to be profoundly related to histological malignancy, tumor(More)
Osteosarcomas are especially rare in the mandible and maxilla, representing 1.6% of all bony malignant tumours. In this article, we described a case of osteosarcoma of the mandible. Computed tomography (CT) image showed a well-circumscribed homogeneous mass, with nonhomogeneous contrast enhancement. T1-weighted magnetic resonance imaging (MR) image showed(More)
Mandibular actinomycosis is an uncommon disease caused by Actinomyces israelii. Actinomycosis infection typically manifests as a chronic disease resulting in multiple abscesses, firm soft tissue mass, and presence of sulfur granules in exudates or tissues. A few reports have provided imaging findings of actinomycosis in the head and neck, but computed(More)
Cisplatin [cis-dichlorodiamine platinum(II)], currently used therapeutically [1], has antitumor activity against a number of human neoplasms [2]. However, it cannot be used for long periods or at high doses because it has adverse effects on renal functions. Naganuma et al. [3] recently reported that co-administration of a selenium compound protected(More)
Central giant cell lesions are rare, benign, osteolytic, pseudocystic, solitary, localized lesions that are common in the skeletal structure, but less so in the maxillofacial region. Furthermore, to perform panoramic radiography and cone-beam computed tomography, it is necessary to prepare patients properly and to position their heads carefully. However,(More)
In this report, we describe image findings in a case of a 78-year-old man with malignant lymphoma of the palate, which had progressively developed 8 years after malignant lymphoma of the neck. The patient was referred to our hospital with a complaint of painless swelling of the left palate. A slightly enhanced mass without apparent bone destruction was(More)
