Notes: Summary To elucidate the degenerating mechanism of the neurons in the intermediate zone of the spinal cord in classical amyotrophic lateral sclerosis (ALS), the spinal neurons in a patient with ALS, whose muscular strength was fairly well preserved up to death, were examined quantitatively and topographically, and compared with the data of advanced ALS patients and age-matched control subjects reported previously. In advanced ALS patients, anterior horn cells completely disappeared and the medium-sized (nuclear area; 71–150 μm2) and large (nuclear area; greater than 151 μm2) neurons in the intermediate zone were severely reduced. In the present case, however, the loss of anterior horn cells was severe but the degree was not equal to that of advanced ALS patients, and the neurons in the intermediate zone were quite well preserved. The finding indicates that the primary degeneration may occur in the anterior horn cells and the neurons in the intermediae zone degenerate sequentially in the spinal gray matter in ALS.

Notes: Plasma polymerization of perfluorobenzene/sulfur dioxide (PFB/SO2) mixture was investigated by elemental analysis, infrared spectroscopy, and XPS. Plasma polymer films like Nafion were obtained from the plasma polymerization of PFB/SO2 mixture. The plasma polymerization deposited fluoropolymers with sulfur moieties including sulfonate and sulfonic acid groups. The elemental composition, F/C, and S/C atomic ratio of the formed plasma polymers were 0.65-0.67 and 0.24-0.27, respectively, which were independent of the starting mixture composition. The polymers showed cation-exchange ability of which the capacity was 0.49 meq/g polymer, and initiated the polymerization of pyrrole.
