Abstract: Aplasia of the corpus callosum or aspermatogenesis is diagnosed by investigating existence or expression of the BT-IgSF gene with use of a primer for PCR or probe for hybridization comprising a DNA coding for a novel cell adhesion molecule (BT-IgSF) defined in the following (A) or (B) or a partial sequence thereof:

Abstract: A protein hydrolysate comprising at least two types of peptides, characterized in that the rate of hydrolysis of protein is from 30 to 45%, the number average molecular weight is 300 or less, and the ratio of a weight average molecular weight to the number average molecular weight is greater than 1 and 2 or less, has excellent emulsifiability, and antigenicity thereof is low enough to be used for people who has predisposition to allergic diseases. This protein hydrolysate is obtained by hydrolysis of a protein starting material to a rate of hydrolysis in the range of 30 to 45%, and then bringing it into contact simultaneously or separately with two types of porous synthetic adsorbent respectively having an average pore radius of 2 to 8 nm and an average pore radius of 20 to 30 nm, the total surface area of the two porous synthetic adsorbents being in a range of 300 to 3000 m2 per 1 g (protein equivalent) of the obtained protein hydrolysate, and recovering the non-adsorbed component.

Abstract: A Lactobacillus bifidus growth promoting composition which significantly grows lactobacillus bifidus and does not produce any side effect such as diarrhea, and a blend comprising the above composition and other edible ingredients, and the composition comprises at least one oligosaccharide selected among lactulose, fructo-oligosaccharide, and galacto-oligosaccharide, and raffinose as the active ingredients.

Abstract: Fine granular feeds for fry of fishes and shellfishes capable of remarkably elevating the survival rate of fry, improving the cultivation efficiency, and causing little elution of nitrogen sources therefrom into seawater or water in feeding, which are characterized by containing at least three active components, i.e., (a) a long-chain unsaturated fatty acid calcium salt blend comprising 80% by weight or more of long-chain unsaturated fatty acid calcium salt(s) having at least 18 carbon atoms, (b) 20% by weight or less of a browned matter formed by heating molasses or saccharides, a browned matter formed by heating saccharides with amino acids or a mixture thereof at an arbitrary ratio, and (c) a mixture of peptides obtained by hydrolyzing animal protein, and being in the form of fine grains.

Abstract: A lactose-containing food compositions for infants for improving the stool color of infants closer to that of breast-fed infants, which contains the lactose-containing foods for infants of which the only protein source is substantially cow's milk protein and/or a processed product of cow's milk protein modified to be administered to infants, and raffinose added into the foods for infants at a ratio of at least 0.05% (by weight) in a ready-to-use state. This food composition provides foods for infants more suitable for infant growth (infant formula, protein hydrolyzed formula, formula for low-birth-weight infants, follow-up formula, etc.) without causing a green stool which is observed when administering a conventional food for sucking infants, of which the only protein source is substantially cow's milk protein and/or a processed product of cow's milk protein.

Abstract: The present invention provides a compound for poultry feeds characterized by making it possible to increase the content of a highly unsaturated fatty acid in the yolk of eggs laid, decrease the percentage of breakage of eggs laid and extend the egg-laying period, and containing a long-chain unsaturated fatty acid calcium salt having carbon atoms of more than 18 alone, or said long-chain unsaturated fatty acid calcium salt together with a molasses, a browning material formed by heating saccharide, a browning material formed by heating saccharide and amino acids and the like as effective ingredients, and a method for feeding poultry characterized by compounding said compound with a poultry feed, and feeding the resultant feed to poultry.
