Abstract: An apparatus and a process for preparing a material, such as a sample, for analysis, observation, recording or the like, at a high accuracy, by a simple construction and simple operation, which can form a cut face and/or a cut rift while preventing deformation, destruction and denaturing of the material. The process involves embedding a part of the material (11) in a filler (13) in a holder (4) of a holding unit (1) under settling with a settling means (5), holding the protruding portion (11b) of the material (11) by a protruding portion support (7) of a mount (2), freezing the material (11) instantaneously by dry ice placed in dry ice wells (6a, 6b) while effecting a gas phase replacement and cutting the material (11) by a cutter (22) to form a cut face (14) and/or a cut rift (15).

Abstract: This invention is to provide an agent for therapy and prevention of allergic diseases which has no adverse action, shows a high safety even by administration for a long period and is able to be utilized to food and/or beverage, cosmetics, etc. which are used daily. To be specific, it provides antiallergic agent and anti-inflammatory agent characterized in containing at least one polyphenol selected from strictinin and methylated derivatives thereof as an effective ingredient; a method for the addition of an antiallergic agent for oral administration or an anti-inflammatory agent for oral administration which is characterized in containing at least one polyphenol selected from strictinin and methylated derivatives thereof as an effective ingredient to food and/or beverage for prevention, suppression and mitigation of allergic symptoms or inflammatory symptoms.

Abstract: For stably and efficiently producing cloned livestock, used is a uniform cultured cell strain as a donor cell for nuclear transplantation.

Abstract: An antibacterial agent is provided, which has an action for inhibiting growth of Helicobacter pylori participating to occurrence of chronic gastritis and gastric ulcer, and a highly safe substance is used as an effective component therein. An antibacterial agent for Helicobacter pylori is characterized in that at least one substance selected from the group consisting of ethylenediaminetetraacetic acid and its metal salts is contained as an effective component.

Abstract: A DNA sequence is provided, which encodes an enzyme that is the &agr;-subunit of the first isozyme of rice anthranilate synthase (ASA). Transformed plants having a high tryptophan content can be regenerated by culturing the plant cells having introduced therein such a recombinant vector which contains, at a position downstream of a promoter, an inserted DNA fragment carrying the above DNA sequence. In addition, methods of selecting transformed plant cells are disclosed, wherein plant cells transformed with the discloses DNA are resistant to inhibitory concentrations of tryptophan or tryptophan analogues.

Abstract: The present invention provides a method and a system for searching for relationships between base sequences in order to efficiently analyze the relationship between a sample base sequence and known base sequences. In the system, a theoretical value calculating portion calculates theoretical restriction fragment length values based on restriction enzyme data. The comparing portion produces analysis result data by comparing theoretical restriction fragment patterns with measured restriction fragment patterns, calculating the degree of similarity of the sample base sequence to known base sequences.
