As a means of improving nerve tract-tracing in the peripheral and central nervous systems we experimented with two (retrograde) fluorescent emulsions, which we have tentatively named Fluoro-Green (FGr) and Fluoro-Red (FRe), and which we believe possess the following seven advantages: (1) they show little diffusion beyond the injection site; (2) their(More)
In an 80-year-old Japanese male cadaver, the right subclavian artery originated from the aortic arch distal to the origin of the left subclavian artery, i.e., it was the last branch of the aortic arch. It coursed obliquely upwards and to the right behind the esophagus and trachea heading for the superior thoracic aperture. Its area of distribution was(More)
The objective of this study was to evaluate the effects of isobutyrate supplementations on rumen fermentation, urinary excretion of purine derivatives and feed digestibility in steers. Eight ruminally cannulated Simmental steers were used in a replicated 4 x 4 Latin square experiment. On DM basis, diet consisted of 60% corn stover and 40% concentrate. Dry(More)
The projection from the retina to the habenular complex was studied using fluorescent retrograde tracers in the albino rat (Wistar, Japan Clea). Following separate unilateral injections of Fluoro-Gold (FG), Fluoro-Ruby (FR), or 4-acetamido,4- isothiocyanostilbene-2,2'-disulfonic acid (SITS) into the lateral habenular nucleus (LHB), a small population of(More)
PURPOSE Several abnormalities in visual pathway functions in diabetic humans and animals have been reported. We demonstrated retrograde axonal transport impairment in retinal ganglion cells of streptozotocin-diabetic rats. METHODS Diabetes was induced in male Wistar albino rats by intraperitoneal injection of streptozotocin. Three months after the(More)
Clinical and electrophysiological examinations have yielded visual pathway function abnormalities in both humans and animal models with diabetes mellitus (DM). However, subclinical involvement of the optic nerve has not yet been fully investigated. In this study, we demonstrated the different impairments in retrograde axonal transport occurring in selective(More)
Our aim was to investigate if the memory-enhancing effects reported for dehydroepiandrosterone sulfate in rodents could be mediated through modulation of NMDA receptors. Using autoradiography we studied the effect of dehydroepiandrosterone sulfate, administered for 5 days (30 mg/kg, i.p. twice a day), on NMDA binding sites labelled with [3H]dizocilpine(More)
Injection of the fluorescent tracers 10% Evans blue (EB) and 4% fluoro-gold (FG) into the right and the left dorsal lateral geniculate nucleus, respectively, of albino rats at different stages of development demonstrated the presence of double-labeled retinal ganglion cells that projected bilaterally into both the dorsal lateral geniculate nuclei (dLGN).(More)
Injection of the fluorescent tracers, Evans Blue (EB) and 4'-6-Diamidino-2-phenylindole dihydrochloride hydrate (DAPI) or Fluoro-Gold (FG) into the dorsal nucleus of the lateral geniculate body (dLGN) and the ipsilateral superior colliculus (SC) of adult cats demonstrated the existence of double-labeled optic nerve cells in the retina denoting that their(More)
To establish the terminal sites of the optic nerve fibers in the albino mouse, the immunohistochemical method using cholera toxin, subunit B (CTB), as well as three kinds of selective silver impregnation methods for degenerating nerve fibers were used. Termination was confirmed in the following nuclei: bilateral dorsal nuclei of the lateral geniculate body(More)
