Abstract: A readily-available brain function-improving agent or food composition having an A? intracerebral deposition suppressing effect or a learning function-improving effect is provided based on finding, as a result of orally administering Pantoea LPS to Alzheimer's disease model mice and studying the effects, that oral administration of Pantoea LPS significantly decreased intracerebral A? peptide accumulation and improved learning function.

Abstract: The present invention relates to a method for evaluating phagocytic capacity of phagocytes, including incorporating a fluorescent substance into phagocytes in a sample containing whole blood to obtain a measurement sample, standing the measurement sample for 2 minutes or more, measuring the fluorescence of the fluorescent substance, and evaluating the phagocytic capacity of phagocytes based on the intensity of the measured fluorescence, in which the measuring the fluorescence of the fluorescent substance includes irradiating an intermediate region of gravity direction of a placed measurement sample with an excitation light, and detecting the fluorescence generated from the fluorescent substance by the excitation light.

Abstract: To provide a pathological index for Alzheimer's disease conveniently and with high precision, an Alzheimer's disease diagnosis device that includes a measurement means configured to measure one index or more selected from the group consisting of superoxide production activity, myeloperoxidase activity, oxidized LDL level, phagocytosis, triglycerides, fasting blood glucose, total cholesterol, hemoglobin A1c, and insulin in peripheral blood and a displaying means configured to display an index measured by the measurement means as a pathological index for Alzheimer's disease.

Abstract: In order to provide a method for culturing an immunopotentiator-containing organism having the experience of being eaten, inexpensively without requiring usage of a component derived from an animal, Acetobacter, Gluconobacter, Xanthomonas, Zymomonas or Enterobacter which is an edible gram-negative bacterium having an immunopotentiation function is cultured using a culture solution composed mainly of wheat or bean curd refuse. Thereby, Acetobacter can be obtained inexpensively and safely, and also a low molecular weight lipopolysaccharide which is the immunopotentiator can be obtained inexpensively and safely. Furthermore, no impurity derived from animal components is mixed.

Abstract: For the purpose of providing a method of safely and inexpensively producing a fermented plant extract containing an immunopotentiator at a high concentration, the method for fermentation and culture of the present invention ferments a plant component such as wheat flour using Pantoea agglomerans which is a gram negative bacterium which lives in a symbiotic relationship with a plant such as wheat and apple. It becomes possible to remarkably augment an immunopotentiation action which the plant has. In addition, these are not contaminated with impurities derived from animal components, and thus these are highly safe.

Abstract: A crushed bacterial cells can be obtained by culturing a gram-negative bacterium and physically crushing a body of the gram-negative bacterium, comprises all components including immunostimulatory components in the bacterial cells, and comprises LPSs having molecular weights of 20,000 or less as active ingredients. The crushed bacterial cells is effective as a health food, drug, skin-care product, bath agent, feedstuff for protecting crustaceans, shellfish, fish, poultry, farm animals and pet animals from infections, and a feed additive for growth promotion, and can provide an innate immunostimulatory substance derived from a gram-negative bacterial cells having infection-preventing effects and growth promoting effects, an inexpensive and practical microbial crushed bacterial cells, and a composition thereof.

Abstract: It has been found that a limulus-positive glycolipid is present in xanthan gum derived from Xanthomonas, which has been commercially available and eaten for many years, and this was purified, and it has been found that this limulus-positive glycolipid has an immunopotentiation effect. A method for safely and inexpensively producing the limulus-positive glycolipid containing an immunopotentiator at high concentrations is provided. The method for producing the limulus-positive glycolipid of the present invention comprises extracting the limulus-positive glycolipid from xanthan gum. A limulus-positive glycolipid composition containing the limulus-positive glycolipid can be used for various applications such as pharmaceuticals, pharmaceuticals for animals, quasi drugs, cosmetics, foods, functional foods, feedstuff and bath agents.

Abstract: It is intended to provide a remedy for diseases caused by macrophages with dysfunction or mediated by macrophages. Namely, a remedy which activates the phagocytic capacity of macrophages and thus is efficiently incorporated into the macrophages due to the vigorous phagocytosis. As a result, the macrophages with dysfunction are normalized, macrophages infected with a pathogen are exterminated or a pathogen in the infected macrophages is exterminated.

Abstract: A disease resistance capacity of vegetables, grasses and flowers, etc., is enhanced and their survival rates are improved by growing plants in an appropriate coexistence of a glycolipid derived from Pantoea agglomerans or a composition containing the glycolipid. Thereby, a method of augmenting disease resistance of vegetables, grasses and flowers, etc., and growing agricultural crops with high quality is provided, and further a novel plant growing agent and plant disease resistance inducer that enables this are provided. As a result, it becomes possible to cultivate agricultural crops or increase productivity with as little use of agricultural chemicals as possible. Even if an amount of the agricultural chemical is reduced, a cultivation success rate of agricultural crops can be enhanced and immunity of the plant body can be enhanced even where useful soil bacteria are not frequently present.
