Abstract: The present invention provides an effective and safe prophylactic and therapeutic pharmaceutical agent and supplement for corneal epithelium disorders and/or conjunctival epithelial disorders. This is a therapeutic and/or prophylactic agent for corneal epithelium disorders and/or conjunctival epithelial disorders comprising eicosapentaenoic acid and/or docosahexaenoic acid, a glycerin ester or phospholipid comprising these fatty acids as constituent fatty acids, or a lower alcohol ester of these fatty acids as active ingredients. These preferably comprise EPA and/or DHA in the form of a refined fish oil or refined krill oil. A total of at least approximately 50 to 5,000 mg of EPA and/or DHA or the esters thereof are taken daily, thereby easing corneal epithelium disorders and/or conjunctival epithelial disorders. In addition, the amount of tears may be recovered.

Abstract: Provided is a composition permitting high systemic absorption of n-3 polyunsaturated fatty acids and high transfer of them to tissues and capable of fully exhibiting pharmacological effects which the fatty acids have. A fat composition containing one or more phospholipids having, as a constituent fatty acid, an n-3 polyunsaturated fatty acid selected from docosahexaenoic acid, docosapentaenoic acid and eicosapentaenoic acid; and ?-linolenic acid and/or a fat containing ?-linolenic acid.

Abstract: The present invention discloses the use, in the manufacture of a preventive and therapeutic drug of a brain disease, of a compound represented by formula (1): CH2═CH—CH2—S(O)n—R  (1) [wherein R represents a hydrogen atom, an alkyl group, an alkenyl group, a substituted alkyl group, a substituted alkenyl group, an alkylthio group, an alkenylthio group, a phenyl group, a substituted phenyl group, a heterocyclic group, or a group derived from an amino acid or an oligopeptide by deletion of one hydrogen atom, and which group may have a protective group; and n is 0, 1, or 2], a glycoside thereof, or a salt of the compound or the glycoside. The drug of the present invention for ameliorating brain diseases, inhibiting reduction of brain neurons and promoting branching of neurites, is useful for the prevention and treatment of brain diseases such as dementia in association with degeneration and sloughing of brain neurons.

Abstract: The present invention discloses a drug for ameliorating brain diseases which comprises as an active ingredient a compound represented by the following formula (1): ##STR1## or a salt thereof. Because of inhibiting a decrease in brain neurons and promoting branching of neurites, this drug is efficacious in the prevention and treatment of dementia, etc. in association with degeneration and sloughing of brain neurons.
