Abstract: The present invention is envisioned to improve sliding characteristics of polyether aromatic ketone resins and to provide their molded articles which are themselves resistant to damage and abrasion, cause no such damage or abrasion to their partner parts and can be easily molded. Thus, the present invention pertains to a polyether aromatic ketone resin composition comprising a polyether aromatic ketone resin and a high-hardness filler having a Mohs hardness of 6 or higher, the content of said filler being 1 to 100 parts by weight per 100 parts by weight of said ketone resin, and furthermore to a film or sheet made of the resin composition. The high-hardness filler having a Mohs hardness of 6 or higher is preferably particulate or spherical in particle shape. Also, the maximal particle size of said high-hardness filler is preferably not larger than 100 &mgr;m.

Abstract: Substituted pyrazole compounds represented by formula (I), or salts thereof are disclosed, wherein R1 is —CH(OH)—CH(R4)-(A)n —Y, —CH2 —CH(R4)-(A)n—Y, —CO—B1-A-Y or the like (wherein A is a lower alkylene; Y is an aryl group which may be substituted, for example, by halogen, or the like; R4 is a hydrogen atom or a lower alkyl group; B1 is —CH(R4)— or —N(R4)—; and n is 0 or 1); R2 is a hydrogen atom, a lower alkyl group which may be substituted by hydroxyl or the like, or an aralkyl group; R3 is a phenyl group which may be substituted by halogen or the like, or a pyridyl group; and Q is a pyridyl or quinolyl group. These substituted pyrazole compounds or their salts have an excellent p38MAP kinase inhibiting effect and are hence useful in the prevention or treatment of tumor necrosis factor &agr;-related diseases, interleukin 1-related diseases, interleukin 6-related diseases or cyclooxygenase II-related diseases.
