Disclosed are an antihyperlipidemia or antiarteriosclerosis agent comprising a certain benzimidazole or 2,2'-methylenebisphenol derivative such as 5-dodecanoylamino-2-mercaptobenzimidazole or 2,2'-isobutylidenebis(4,6-dimethyphenol).

Treating arteriosclerosis using benzimidazole compositions

A method of treating photographic processing wastes is disclosed. The method comprises (1) mixing a silver-recovery system waste and a development system waste from photographic processing to produce a waste mixture, (2) adding to said waste mixture phosphorus as a nutritive substrate in an amount corresponding to at least 2% based on the COD value of the waste mixture, and (3) subjecting the resulting waste mixture to a bio-oxidation treatment using microflora containing sulfur-oxidizing bacteria. The method enables a continuously treatment of high concentration photographic processing wastes with high efficiency over a long period of time.

Method of treating photographic processing wastes

A silver halide color photographic light-sensitive material comprises a novel cyan dye-forming coupler or a combination of a specific cyan dye-forming coupler with an .alpha.-pivaloylacetoanilide type yellow dye-forming coupler or a pyrazoloazole type magenta dye-forming coupler, the specific cyan dye-forming coupler being contained in the silver halide emulsion layer in the form of an emulsion of lipophilic fine particles obtained by mixing the coupler with at least one water-insoluble and organic solvent-soluble homo- or co-polymer to form a dispersion. The silver halide color photographic light-sensitive material is excellent in the reproduction of yellow, magenta and cyan colors and has low fog of cyan. Thus, the light-sensitive material can provide color images excellent in the fastness of the cyan color images.
