Abstract: The present invention provides a crude drug composition comprising extracts of radish and tea leaf and additionally comprising an extract extracted from at least one crude drug selected from a group consisting of Daucus carota var sativa, Aurantii nobilis Pericapium, Aurantii immatri Pericarpium, Ficus carica L., Allium cepa L., Mume Fructus and Prunus armeniaca. Inventive composition induces the functional activation of intestine in the charcoal-administered animal model experiment and constipation-induced animal model and improves the constipation by activating mucus secretion in the intestine. And the composition is confirmed to inhibit the growth of intestinal harmful bacteria without affecting the growth of beneficial bacteria. Therefore, the crude drug composition of the present invention may be useful for the pharmaceutical composition and health care food for preventing, alleviating and treating intestinal disease and constipation.

Abstract: An electrochemical cell employs an ionic semiconductor material as a separator between an anolyte and a catholyte. Ionic semiconductor material includes 10 to approximately 50 percent by weight of a hydrogel which is dispersed within an inert nonporous matrix material to form a composite wherein the quantity of water that can be absorbed by the composite does not substantially exceed the weight of the composite.

Abstract: An electrode comprising: metallic electrode material; and a nonporous solid composite material encapsulating the electrode material, the composite material comprising an inert matrix material having hydrogel substantially uniformly dispersed therein, the hydrogel comprising 10% to approximately 50% by weight of the dry composite material, there being sufficient bonding between molecules of the hydrogel and the matrix material to prevent substantial leach-out of hydrogel molecules from the composite.

Abstract: An ion transport membrane includes 10 to approximately 50 percent by weight of a hydrogel which is dispersed within an inert nonporous matrix material to form a composite wherein the quantity of water that can be absorbed by the composite does not substantially exceed the weight of the composite. The membranes may be used in electrochemical cells, for water purification, as solid polymeric electrolytes, in breathable waterproof coatings, and in numerous other applications for controlled moisture or ion transfer.
