Abstract: A method for administering a drug to a diseased portion is achieved in a short time and predominantly improves the administration amount (transdermal permeation amount) of the drug in treatment of eyelid disease or palpebral conjunctiva disease. The method for administering a drug for treatment of eyelid disease or palpebral conjunctiva disease includes a step of microneedle perforation by using a microneedle device into a tissue of the eyelid including a meibomian gland of a patient suffering from or suspected of having the disease, in which drug-containing coating is applied to at least a part of a surface of the microneedle, and the drug is a water-soluble drug.

Abstract: [PROBLEMS TO BE SOLVED] To provide a method of advantageously improving a transdermal permeation amount of a steroid drug to diseased portions when treating ophthalmic diseases such as chalazion, blepharitis, allergic conjunctivitis, vernal keratoconjunctivitis, and meibomian gland dysfunction. [SOLUTION] To provide the transdermal drug delivery system for administering a drug via the eyelid skins that have been treated with a microneedle array, featured in that the drug is a water-soluble steroid, and the transdermal drug delivery system is a water-containing base adhesive skin patch.

Abstract: The present invention aims to provide a means for effectively and conveniently treating diseases wherein corneal endothelial cells poor in proliferative capacity in vivo are damaged. The present invention provides a therapeutic agent for corneal endothelial dysfunction containing (R)-(+)-N-(1H-pyrrolo [2,3-b]pyridin-4-yl)-4-(1-aminoethyl)benzamide <Y-39983> or a pharmacologically acceptable salt thereof (compound (Ia)) as active ingredient, an agent for promoting adhesion of corneal endothelial cells, containing compound (Ia), a culture medium for corneal endothelial cells, containing the agent for promoting adhesion, an implant for corneal endothelial keratoplasty, containing corneal endothelial cells, scaffold and compound (Ia), and a production method of a corneal endothelial preparation, including a step of cultivating corneal endothelial cells using the culture medium.

Abstract: The disclosure provides methods and ophthalmic NSAIDs as adjuvants to VEGF inhibitors useful for treating retinal disorders, including but not limited to wet AMD, diabetic retinopathy, diabetic macular edema, central retinal vein occlusion, and branch retinal vein occlusion.

Abstract: A method for manufacturing a printed circuit board includes: washing a land that corresponds to the exposed portion of a copper circuit of a printed circuit board with acidic electrolytic water having a pH of not more than 5 to remove an oxide; treating the land with basic electrolytic water having a pH of not less than 9 to prevent oxidation; and soldering electronic components to the land. The portion to be soldered is treated with the electrolytic water beforehand, thereby improving soldering at low cost without any adverse effect on the environment.
