Fine structure of the noradrenaline (NA) nerve terminals in the dorsomedial portion of the nucleus tractus solitarii (NTS) was investigated by glyoxylic acid-potassium permanganate fixation method. The NA nerve terminals in this area contained a large number of small cored vesicles (SCV) (about 400-600 A in diameter) together with a few large cored vesicles(More)
The noradrenergic terminals in the substantia gelatinosa of the dorsal horn of the cervical spinal cord of the rat were investigated by means of the histofluorescence technique and electron-microscopic cytochemistry using the glyoxylic acid-KMnO4 fixation technique. In accordance with the topographical distribution of fluorescent catecholaminergic fibers,(More)
Heterogeneity of adult rat neostriatum has been studied by fluorescence histochemistry. The distribution of dopamine nerve fibers and terminals, known normally to be homogeneous, tended to become heterogeneous after administration of methamphetamine or reserpine. Both drugs caused mosaic formations of fluorescent dopamine axons and terminals, though a minor(More)
OBJECTIVE Delineation of the interlobar fissures on multiplanar reconstruction (MPR) images is useful to assess masses at the fissures for invasion into adjacent lobes. We performed this study to determine the appropriate MDCT protocol to visualize the interlobar fissures on sagittal MPR images. MATERIALS AND METHODS For the phantom studies, radiographic(More)
The influence of acute methamphetamine treatment on serotonin-like immunoreactive axons was studied in the rat forebrain. Animals, sacrificed 90 min after i.p. injection of methamphetamine (16 mg/kg) or saline, were processed for immunocytochemistry using serotonin antiserum. The numerical density of immunoreactive boutons of terminals and varicosities was(More)
Details of seizure stage progression in amygdala kindling were studied in the cat under local denervation of catecholamine input to the amygdala. A chemitrode was used for both electrical stimulation and continuous infusion of 6-hydroxydopamine. The extent of denervation was confirmed by fluorescence histochemistry. The result has indicated that(More)
