Eye-fixation patterns while viewing simple patterns were quantitatively analysed in homonymous hemianopic subjects with or without unilateral spatial neglect (USN), using an eye camera. Hemianopic subjects without USN used the strategy to look at the hemianopic side of the patterns longer in order to compensate for their visual field defect. However, those(More)
Patients with unilateral spatial neglect fail to report or respond to stimuli contralateral to the lesion which usually involves the right parietal lobe. When asked to mark the centre of a horizontal line, these patients place the mark to the right of the true midpoint. It has been considered that they neglect the left part of the line and bisect the(More)
BACKGROUND AND STUDY AIMS Growing evidence suggests that esophageal stricture frequently develops after endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) in early esophageal cancer patients, with an incidence proportional to the greater extent of mucosal defects resulting from improved EMR/ESD techniques. There seems to be a(More)
To clarify the characteristics of parkinsonian and ataxic gaits, we analyzed electromyograms (EMGs) of the thigh and leg muscles, angular displacements of the hip and leg joints, and floor reaction forces during free walking for each gait phase in 16 patients with Parkinson's disease (PD) and 14 ataxic patients with cerebellar degenerations. We studied 17(More)
A clinicopathological study was made on 65 patients from a small area of Nagano Prefecture, Japan, with hereditary generalized amyloidosis with polyneuropathy to clarify the clinical variety of the disease. Forty-five patients from Ogawa village showed similar clinical features. The age of onset ranged widely from 16 to 62 years. The main neurological(More)
Quantitative changes in unmyelinated nerve fibres in sural nerves obtained at autopsy were evaluated in 28 normal adults. The following conclusions were reached. (1) The density of unmyelinated axons showed no significant correlation with age, but the densities of (2) Schwann cell subunits with axons, (3) Schwann cell subunits without axons, (4) single(More)
By use of radioimmunoassay (RIA) specific for endothelin-1 (ET-1), we have studied whether ET-1-like immunoreactivity (LI) exists in human cerebrospinal fluid (CSF). Human CSF from patients with old cerebrovascular disease contained far greater amounts of ET-1-LI (28 +/- 1.3 pg/ml, n = 9) than normal human plasma. Reverse-phase HPLC coupled with ET-1 RIA(More)
Morphometric studies by histological and teased-fiber methods on myelinated fibers of the C6 and C8 ventral roots were made in cases of myotrophic lateral sclerosis (ALS) and in age-matched controls. In 11 controls myelinated fibers were divided into two groups: large and small fibers. The fiber density was calculated and the actual number of fibers was(More)
Gastrointestinal amyloid deposition was investigated in 21 autopsy cases of nonhereditary systemic amyloidosis, 18 of the AL (primary or myeloma-associated) type and three of the AA (secondary) type. Vascular deposition of amyloid, most apparent in the submucosa, was found in all cases. Parenchymal deposition was observed mainly in the muscularis mucosae(More)
