Abstract: This invention provides a plated steel wire with high corrosion resistance and excellent workability, wherein the average composition of the plating alloy in the plated steel wire comprises, in terms of weight percentage, Al: 4-20%, Mg: 0.8-5%, and if necessary one or more from among Si: ≦2%, Na: 0.001-0.1% and Ti: 0.01-0.1%, with the remainder Zn, and an Fe—Zn alloy layer of no greater than 20 &mgr;m thickness is present at the plating-base metal interface; it is produced by coating a steel wire with a molten zinc plating composed mainly of zinc as the first stage and then.coating it with a molten zinc alloy plating with the aforementioned average composition as the second stage. The maximum plating bath immersion time is 20 seconds, and the part of the plated steel wire drawn out from the plating bath is purged with nitrogen gas.

Abstract: The object of the present invention relates to a plated steel material and a method of production the same, having enhanced corrosion resistance and workability required for outdoor and exposed uses such as structures, revetments, fishing nets, fences, etc.

Abstract: A coated steel material excellent in corrosion resistance and a method of producing the same, wherein a coated steel material has on the surface of the steel sheet a Zn-alloy coating layer containing 1-10 wt % of Mg, 2-19 wt % of Al and 0.01-2 wt % of Si, where Mg and Al satisfy Mg (%)+Al (%)≦20%, the balance being Zn and unavoidable impurities, and has a coating layer structure of a Mg intermetallic compound or the like. As a base metal treatment, it is preferably provided with a Ni coating layer. The coated Zn-alloy coated steel sheet may have provided on the coating layer, as an intermediate layer, a chromate film layer, and, as an upper layer, an organic coating layer. The Zn-alloy coating layer may further contain one or more of 0.01-1 wt % of In, 0.01-1 wt % of Bi and 1-10 wt % of Sn. The coated steel material may be painted.

Abstract: N-(12-Nitroxydodecyl)-6-(4-ethyl or isopropyl-1-piperazinyl)pyridine-3-carboxamide or physiologically acceptable salts thereof. The said compounds have excellent inhibiting activity of cerebral edema, especially ischemic cerebral edema, and inhibiting activity of delayed neuronal death (an inhibiting activity of Ca-influx in neuronal cells). Cerebral edema is a pathologic condition accompanying cerebrovascular disorders, especially the acute stage cerebrovascular disorders and then the compounds are useful as an inhibiting agent for cerebral edema or a therapeutic agent for cerebrovascular disorders. Moreover, because the compounds do hardly show a behavior suppressing action, which is considered to be side effect in treating cerebrovascular disorders at the acute stage, they are an excellent therapeutic agent for, in particular, the acute stage cerebrovascular disorders.

Abstract: Pyridinecarboxamide derivatives of the formula ##STR1## (wherein n represents an integer of 14-18, and R represents a hydrogen atom or a straight or branched C.sub.1 -C.sub.4 alkyl group) or physiologically acceptable salts thereof. The compounds have excellent inhibiting activity of cerebral edema, especially ischemic cerebral edema, and inhibiting activity of delayed death of neuronal cells (an inhibiting activity of Ca-influx in neuronal cells). Cerebral edema is a pathologic condition accompanying cerebrovascular disorders, especially the acute stage of cerebrovascular disorders and then the compounds are useful as an agent for inhibiting cerebral edema or a therapeutic agent for cerebrovascular disorders. Moreover, the compounds have no hypotensive action which is considered to be side-effect in treating the acute stage cerebrovascular disorders and hardly show a behavior suppressing action so that they are an excellent therapeutic agent for, in particular, the acute stage cerebrovascular disorders.
