Abstract: Ophthalmic adhesive preparations for percutaneous absorption to be used in treating diseases in the posterior parts of eye characterized by having a drug-containing layer which contains a drug to be delivered to the posterior parts of eye including the crystalline lens, the vitreous body, the uvea and the retina, together with a percutaneous sorbefacient comprising polyoxyethylene oleyl ether and/or isopropyl myristate uniformly dispersed in a base matrix.
Abstract: An experimental instrument for examining permeability of a flowing cornea is used for imitating a lacrimal layer in the front part of a cornea or the back part of the cornea (an aqueous humor) by means of storing a various kinds of solutions comprises a cell body including a stirring part of a cylindrical wall and a bottom surface at a bottom part thereof, a constant temperature tank which surrounds the cell body all around a sample membrane setting part which is protrusively arranged at an outer surface of the call body and can set a sample membrane such as a contact lens used as a cornea or a corneal model, an outflow tube which is protrusively arranged at an outer surface of the stirring part and makes a solution in the cell body discharge, an inflow tube which is protrusively arranged at an upper part of the cell body and makes the solution flow inside of the cell body, a magnet rotator which is arranged inside the stirring part of the cell body, and a magnet stirrer which makes the magnet rotator inside
Abstract: A micro-flow controlling pump according to the present invention is used for controlling a micro-flow of a liquid in an experiment using a chemical agent for examining permeability of a membrane, reaction of a flow system, reflux of vital tissues, or the like. The micro-flow controlling pump includes: a pump body formed to have a cylindrical wall and a bottom surface, and be provided with an outflow tube formed at an outer surface of the cylindrical wall; a cover body formed to be detachably attached to the pump body and be provided with an inflow tube; a magnet rotator arranged inside the pulp body having criss-crossing blade parts; and a magnet stirrer arranged outside the pump body, having magnetic force by which the magnet rotator in the pump body can be rotated.
