Abstract: The object of the present invention is to provide a humanized or mouse-human chimeric anti-podoplanin antibody or an antibody fragment containing the antigen-binding region thereof, and the object is achieved by providing an isolated humanized or mouse-human chimeric anti-podoplanin antibody which comprises a predetermined amino acid sequence, or an antibody fragment containing the antigen-binding region thereof.

Abstract: Object of present invention to overcome a problem of a dispersion of an evaluation of gas barrier property depending on absorbed moisture of plastic, and carry out measurements in which a measurement value response is good and accuracy is good, wherein from the beginning of a container the gas barrier property of a plastic molded body does not depend on the amount of moisture absorbed thereof. A method of measuring the gas barrier property of the plastic molded body such as a plastic container, a plastic sheet or a plastic film or the like which uses a gas analyzer to measure the amount of permeation of a measurement object gas permeating through the plastic molded body, comprising: a heat drying process which heats and dries said plastic molded body in a temperature range which does not cause deformation or heat deterioration.

Abstract: A propolis food product that contains propolis active ingredients with improved bio-absorbability and is readily ingested. The propolis food products containing propolis extracts are gelled by gelatinizers. The gelantinizers are materials such as shiitake extracts, curdlan, agarics extracts and further including sulfated saccharides, .beta.-glucans, carrageenan, locust bean gum, xanthan gum, or agar. The propolis food products are prepared by water or alcohol extraction. Furthermore, the steps involve preparing a gelantinizer solution by adding a gelatinizer to water and adding propolis extracts thereto so that the amount of the propolis extracts in the food product is from 2 to 25 w/w %, a gel composition is then formed by admixing the solution in order to uniformly disperse the propolis extracts.
