Imaging findings of the developing temporal bone in fetal specimens.
PURPOSE To trace the development of the normal fetal temporal bone by means of plain radiography, MR, and CT. METHODS Eighteen formalin-fixed fetal specimens, 13.5 to 24.4 weeks' gestational age, were examined with a mammographic plain film technique, CT, and MR imaging at 1.5 T. Temporal bone development and ossification were assessed. RESULTS The membranous labyrinth grows with amazing ra...
متن کاملMetastatic Adenocarcinoma of Temporal Bone with Collet-Sicard Syndrome
Introduction: Metastatic tumors of the temporal bone are extremely rare. Collet-Sicard syndrome is an uncommon condition characterized by unilateral palsy of the lower four cranial nerves. The clinical features of temporal bone metastasis are nonspecific and mimic infections such as chronic otitis media and mastoiditis. Case Report: This report describes a rare case of metastatic adenocarcino...
متن کاملBone Marrow Specimens
A series of 20 bone marrow trephines biopsy and necropsy specimens were stained for IgA1 and IgA2 activity, together with total IgA, by means of an indirect immunoperoxidase technique using murine monoclonal antibodies applied to paraffin sections. The specimens showed normal histology and had been taken from patients not known to be suffering from haematological or related systemic disease. Th...
متن کاملTHE BEST DURATION OF LOW INTENSITY PULSED ULTRASOUND FOR ACCELERATING FRACTURED-RADIAL BONE REPAIR
We have already shown that low intensity pulsed ultrasonic treatment increases rabbit radial fracture healing. The present experiment was undertaken to find out the best duration for treatment. A complete transverse fracture was made in the right radial bones of21 adult male rabbits by a Stanley knife. The animals were divided into 4 groups: group 1, control groups 2, 3, and 4, experimental...
متن کاملHigh-resolution AFM imaging of intact and fractured trabecular bone.
Nanoscale structural analyses of biomineralized materials can frequently help elucidate important structure-function relationships in these complex organic-inorganic composites. Atomic force microscope (AFM) imaging of the exterior surface of trabecular bone reveals a densely woven structure of collagen fibrils, banded with a 67-nm periodicity, and densely packed mineral plates. The mineral pla...
