    Notes: Abstract A 53-year-old woman developed bulbar palsy, spastic quadriplegia, amyotrophy, and supranuclear ophthalmoplegia, and thereafter her condition was managed with mechanical ventilation for 1 year. Her total clinical course was 6 years. The autopsy examination revealed neuronal loss with reactive astrocytosis in the precentral cortex, thalamus, mammillary body, amygdala, putamen, globus pallidus, subthalamic nucleus, and the substantia nigra, in addition to degeneration of lower motor neurons, some of which contained Bunina bodies. Along the corticospinal tract, there were severe axonal loss and numerous axonal spheroids, which were positive for phosphorylated neurofilament, ubiquitin, and synaptophysin, and lipid-laden macrophages in the centrum semiovale to the crus cerebri. Ballooned neurons, which were positive for phosphorylated neurofilament, were occasionally seen in the frontal cortex. Although in the common form of amyotrophic lateral sclerosis (ALS) both upper and lower motor neurons are mainly involved, the corticospinal tract degeneration cannot be traced rostral to the pons. The noteworthy features in our patient were the precentral cortical degeneration and axonal spheroids in the corticospinal tract rostral to the pons. It remains unclear why axonal spheroids in the corticospinal tract and precentral cortical degeneration are not observed in most ALS cases. Whether their development depends on the clinical duration, mechanical ventilator management, or some other factors remains an open question.

    Notes: Boss forming, which is sometimes called hub forming, has attracted its attention as anenvironment-friendly rotary forming process to form a circular plate with a hole into a boss shape.An experimental study was conducted to survey the technological possibility of boss forming. Bossforming of A1050-O commercially pure aluminum plate of 10 mm thickness was carried out atroom temperature under various working conditions. The effects of the working conditions on themetal flow in boss forming were clarified experimentally

    Notes: Abstract We report a rare case of miliary brain metastases presenting with symptoms similar to encephalitis (“carcinomatous encephalitis”). Contrast-enhanced MRI demonstrated miliary metastases more distinctly than other imaging methods and reproduced the pathological features.

    Notes: Abstract. It has been suggested that cytokeratin 19 is expressed in regenerated bronchoepithelial cells in patients with pulmonary fibrosis, and serum cytokeratin 19 fragment is elevated in patients with pulmonary fibrosis. We hypothesized that serum antibodies to cytokeratin 19 may be formed in patients with pulmonary fibrosis. To prove the existence of anti-cytokeratin 19 antibodies in patients' sera, human recombinant cytokeratin 19 was stained with patients' sera by a Western immunoblot. Then, we tried to establish an enzyme-linked immunosorbent assay to quantitate anti-cytokeratin 19 antibody in the sera of patients with idiopathic pulmonary fibrosis (IPF) and pulmonary fibrosis associated with collagen vascular disorders (PF-CVD). We demonstrated the anti-cytokeratin 19 antibody in patient' sera by a Western immunoblot. In patients with IPF and PF-CVD, significantly high anti-cytokeratin 19 antibody was demonstrated compared with normal volunteers, patients with chronic bronchitis, and patients with pneumonia. These results suggest that anti-cytokeratin 19 antibody may have played a role in the process of lung injury in pulmonary fibrosis.

    Notes: Abstract We conducted a trial to determine whether or not head-shaking nystagmus (HSN) was influenced by lateral head tilting. Twenty-two patients with unilateral peripheral vestibular lesions were examined between July 1990 and June 1996. All of the patients were found to have horizontal HSN following horizontal head shaking in the upright head position. Eye movements were recorded by electronystagmography with the eyes open in complete darkness. Patients voluntarily tilted their heads to the lateral head positions with the assistance of the examiner as quickly as possible immediately after head shaking in the upright head position. Findings showed that monophasic horizontal HSN and the first phase of biphasic horizontal HSN were suppressed by lateral head tilting. The second phase of biphasic horizontal HSN was influenced differently by head tilting when compared with the first phase. Vertical (down-beating) components in horizontal HSN may appear in the peripheral vestibular lesions, but seem to have no definite relation to head positions.
