Abstract
A nerve conduction model is constructed by using some liquid-membrane cells that mimic the function of the K+ and Na+ channels. By imitating two types of Na+ channels (ligand-gated Na+ channels and voltage-gated Na+ channels), a new mechanism for the directional propagation of the action potential along the axon toward the axon terminal is proposed. When the nerve cell is excited by an external (outer) stimulus, it can be presumed that the ligand-gated channels work as power sources at the synapse to propagate the change in the membrane potential, and then the voltage-gated channels locally assist the propagation at each site of the axon (nodes of Ranvier).

Abstract
The electrode reaction of Pu3+/Pu couple at the interface between LiCl-KCl eutectic melt containing PuCl3 and liquid Bi phase was investigated by cyclic voltammetry at 723, 773 and 823 K. For comparison, the system was also studied using a solid Mo electrode in place of the liquid Bi electrode. It was found that the electrode reaction of Pu3+/Pu couple at the Bi electrode was almost reversible. The redox potentials of Pu3+/Pu couple at the liquid Bi electrode in the LiCl-KCl eutectic melt containing 0.87 wt% PuCl3 (0.0014 mole fraction) at 723, 773 and 823 K were observed to be more positive by 0.575, 0.572 and 0.566 V, respectively, than those at the Mo electrode. These differences in potential were thermodynamically analyzed by assuming a lowering of the activity of Pu in Bi phase according to the alloy formation of PuBi2.

Abstract
Seventeen patients who manifested anosmia or hyposmia after long-oral administration of Tegafur (FT-207) in postoperative chemotherapy for cancer were followed up. Anosmia improved in 9 of 17 patients (52.9%), and the recovery period was between 3 and 42 months after the manifestation, and between 1 and 35 months after discontinuation of FT-207. Rhinoscopy and radiography revealed no abnormal findings in the nasal septum, rima oflactoria, concha nasalis media, sinus ethmoidales, etc. As it took a long time to recover from these signs and symptoms, they were presumed to be due to reversible neurological anosmia or hyposmia.
