Description

  The present invention relates to an antiallergic agent and food and drink having a degranulation inhibitory effect.

  In recent years, allergic diseases such as hay fever and atopic dermatitis are increasing in a wide range of ages regardless of gender. Allergic diseases are defined as “diseases caused by an immune response to an antigen that would otherwise be harmless”. Although the pathogenesis of allergic diseases is still unclear, the balance of cytokines produced by Th1 and Th2 cells among helper T cells is disrupted, resulting in excessive production of immunoglobulin E (IgE) antibodies. It is inferred. That is, the IgE antibody exhibits a strong effector action on mast cells present in the vicinity of blood vessels and connective tissues, and a kind of basophils of leukocytes present in blood. Mast cells and basophils are cells rich in granules containing pharmacologically active amines such as histamine and serotonin. On these cells, there is a receptor that binds IgE antibody and strongly binds IgE antibody. When an antigen binds to an IgE antibody, intracellular granules are released to the outside of the cell. As a result, histamine, serotonin, and leukotriene are released, causing smooth muscle contraction and increased capillary permeability. Removal of the bound material is promoted. If this degranulation reaction is induced excessively, itchy as an allergic reaction, and symptoms such as so-called pruritus appear.

  Treatment methods for allergic diseases start by removing the causative allergen or not ingesting it, and pharmacological treatments such as antihistamines and steroids are performed depending on the symptoms and onset mechanism. However, pharmacotherapy is not effective depending on constitution, and there is a risk of side effects caused by taking for a long time, which is a problem. A safe antiallergic agent that is effective against such allergic diseases and has no side effects is desired.

The α-D-glucopyranosylglycerols according to the present invention are known substances, and have low browning, low Maillard reactivity, heat stability, non-cariogenicity, indigestibility, and high moisture retention. However, it has been reported that it can be used for foods, chemical products, and pharmaceuticals (see Patent Document 1 and Patent Document 2). Further, α-D-glucopyranosylglycerol is a vascular endothelial cell growth promoting factor production promoting action (see Patent Document 3), a blood glucose level increase inhibiting action (see Patent Document 4), an antibacterial action (see Patent Document 5), Cell activation (see Patent Document 6), dermal matrix production promoting action (see Patent Document 7), neutral fat accumulation inhibitory action (see Patent Document 8), melanin production inhibitory action (see Patent Document 9), skin irritation reducing action (Refer patent document 10) The effect | action (patent document 11) which suppresses the feeling of tightness and a squeak after skin washing | cleaning is reported. However, nothing has been known so far regarding the antiallergic action of α-D-glucopyranosylglycerols.
