Abstract: It is the matter to be solved by the present invention to provide mRNA coding for the PGT of a human brain type and to provide a polynucleotide coding for the PGT of a human brain type prepared using the said mRNA as a template. There are provided mRNA coding for the PGT of a human brain type and having a molecular weight of 38-40 kilodaltons and a polynucleotide being prepared by the use of the said mRNA as a template and having a specific base sequence represented by SEQ ID NO: 2 of the Sequence Listing.

Abstract: A therapeutic agent for spinal canal stenosis is provided, which contains a pyridazinone compound of the formula (I) wherein R1, R2 and R3 are each independently a hydrogen atom or a lower alkyl, X is a halogen atom, a cyano or a hydrogen atom, Y is a halogen atom, a trifluoromethyl or a hydrogen atom, and A is a C1-C8 alkylene optionally substituted with a hydroxyl, or its pharmacologically acceptable salt.

Abstract: An advertisement posting scheme utilizes a comprehensive information viewing device capable of displaying multiple Web pages on a display screen by enlarging or contracting each Web page at arbitrary magnification rate smoothly, rotating each Web page at arbitrary angle smoothly, arbitrarily varying and controlling transparency level of a plurality of Web pages that are arranged in superposition such that any overlapped hidden portion can be made visible, and three-dimensionally arranging the multiple Web pages such that the multiple Web pages can be viewed from arbitrary angle, for the purpose of displaying advertisements on the display screen at arbitrary positions, angles, sizes and transparency levels, in relation to the multiple Web pages.

Abstract: A circulatory disorder improving agent comprising, as an active ingredient, a dihydropyridine derivative of the formula (I) ##STR1## or an acid addition salt thereof. Said circulatory disorder improving agent is particularly useful as an organ circulation disorder improving agent or peripheral circulation improving agent.

Abstract: In a suspension arm formed by press working a plate-shaped member, in a case in which, while a vehicle is traveling, a load is inputted to the suspension arm in a direction intersecting a direction in which the suspension arm swings, at least a region at which a maximum stress is generated is a non-end portion of the plate-shaped member. Accordingly, high rigidity can be ensured without an increase in weight.

Abstract: A novel pharmaceutical use of a dihydropyridine derivative of the formula (I) ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are the same or different and each is an alkyl or the like; R.sub.4 is a hydrogen atom or the like; R.sub.5 is nitro, a halogenated alkyl, cyano or the like; X is a vinylene or an azomethine; A is an alkylene; and B is --N(R.sub.6) (R.sub.7) or a group of the formula ##STR2## wherein R.sub.6 and R.sub.7 are the same or different and each is an alkyl, an aralkyl, an aryl or the like; R.sub.8 and Ar are aryl or the like; and n is 0, 1 or 2, or an acid addition salt thereof for promoting PGI.sub.2 production, and for the treatment and prevention of hyperlipemia, arteriosclerosis and cerebral diseases.
