Description

  The present invention relates to mineral-adjusted water that can effectively suppress or improve atopic dermatitis, a method for producing the same, and the like.

  Water accounts for about 70% of the cell mass of the living body and is a main component constituting the living body. As is well known, water plays an important role in keeping the temperature of a living body constant because specific heat is the largest among substances. In addition, water has a large surface tension and has a function of spreading blood and body fluid to the periphery of the living body by capillary action. In addition, water dissolves proteins, nucleic acids, and sugars that are important for living organisms, and has an important role as a reaction solvent in in vivo chemical reactions for life support activities such as metabolism and energy generation of in vivo substances. ing. Thus, water is an indispensable component for a living body.

Humans take water directly or orally from various foods. The water that humans drink on a daily basis includes various mineral ions such as calcium ions (Ca ²⁺ ), magnesium ions (Mg ²⁺ ), sodium ions (Na ⁺ ), and potassium ions (K ⁺ ). ing. These mineral ion contents vary depending on the region from which the mineral ions are collected, topography, geology, or the preparation method after collection. Among the mineral ions contained in water, calcium ions and magnesium ions are said to have the greatest influence on the taste of water. For this reason, the content of these two mineral ions contained in water is the hardness shown below. Is displayed. Examples of water hardness display methods include German hardness, American hardness, French hardness, and British hardness. For example, German hardness indicates the total amount of calcium ions and magnesium ions contained in 100 ml of water by the corresponding oxidation. It is defined as the mass (mg) converted to the amount of calcium (CaO). The American hardness is defined as the mass (mg) obtained by converting the total amount of calcium ions and magnesium ions contained in 1 L of water into the corresponding amount of calcium carbonate (CaCO ₃ ). German hardness (unit: “° dH”) and American hardness (unit: “ppm”) have a relationship of 1 ° dH = 17.8 ppm. Hardness is an index for classifying water. For example, for classification of water based on American hardness, “Detergent / Washing Encyclopedia”, Motoki Minagawa, Fumiko Fujii, Katsumi Oya, published by Asakura Shoten Co., Ltd., 282- This is shown on page 284, January 10, 2004, the second print.

  In general, water having low hardness, that is, water containing calcium ions and magnesium ions and having a small total amount of these mineral ions is said to be refreshing over the throat, and in particular, water having a hardness of 10 to 100 ppm. Is called “delicious water”.

  It is known that calcium ions and magnesium ions contained in water not only affect the taste, but also have various effects on the living body. For example, many epidemiological survey results have been reported regarding the relationship between calcium ion and magnesium ion concentrations contained in drinking water and the onset of diseases, particularly ischemic heart diseases such as myocardial infarction. According to it, in general, there are some reports that mortality due to myocardial infarction is low in areas where water with high calcium ion and magnesium ion concentration (so-called water with high hardness) is ingested (Non-patent Document 1, 2). According to a report on calcium ion and magnesium ion concentrations in water and mortality due to myocardial infarction (see Non-Patent Document 3), magnesium mortality due to heart attack or cardiovascular disorder is highly negatively correlated. It is said to be ion concentration. In addition, in Japan and Europe, epidemiological findings have been reported that the incidence of atopic eczema increases when humans routinely use water with high calcium and magnesium ion concentrations (non-patent literature). 4, 5). According to Non-Patent Document 5, in the results of a survey conducted on children aged 6 to 12 years, the frequency of atopic eczema is higher in children who are taking water with high calcium ion and magnesium ion concentrations. It was reported that these were significantly higher than those of children taking water with low mineral ion content. Similar epidemiological findings have been reported by a British group (see Non-Patent Document 6). Although the cause and mechanism that water induces atopic eczema has not been elucidated, in areas where water with high calcium ion and magnesium ion concentration is used, soap foam is poor, so the amount used is increased, As a result, the amount of soap that comes into contact with or remains on the skin has increased, and it has been speculated that it may be due to irritation of the skin.

  Under such circumstances, in this field, it is considered that there is some relationship between water and atopic dermatitis, and water that can suppress or ameliorate atopic dermatitis through daily use by humans. It was a crane head.

Statistical analysis Comparison between the control group and the test group was performed using commercially available statistical analysis software [“JMP Ver. 4 ”(manufactured by SAS Institute) was subjected to a multiple comparison test by the Dunnett method, and when p <0.05, it was determined that there was a significant difference.

6). Results and Discussion (1) Body Weight, Feed Intake, Drinking Water Intake, and Skin Water Content Drinking water in group K mice fed with control water and groups A through J fed test water 1-10 There was no significant difference in body weight, feed intake, drinking water intake, and skin moisture content due to the difference in the above.

(2) Onset of human atopic dermatitis-like symptom Human atopic dermatitis in any of group K mice fed with control water and group A to J mice fed any of test water 1 to 10 The following symptoms were observed. Group A, G or J mice that received test water 1, 7 or 10 were all treated with control water (such as the degree of infiltration of inflammatory cells into dry skin and dermis). All the symptoms of the B to F group, H group and I group mice that received the test water 2 to 6, 8 or 9 were “equivalent” to the mice, but the control group was ingested the K group There was a clear tendency to suppress compared to mice (see “Results” column in Table 2).

(3) Histological analysis of the buttock skin After the completion of the 10-week rearing test, the groin of group K mice fed with control water and the mice of groups A to J fed with any of test water 1 to 10 When histological analysis was performed on the skin, symptoms in the B to F group, H group, or I group mice that received test water 2 to 6, 8, or 9 (thickening of the epidermis layer = human atopic dermatitis-like) As the symptom progressed, the thickness increased) was clearly “suppressed” compared to the K group mice fed with control water (see “Results” column in Table 2).

(4) Production of cytokines in spleen cells Spleen cells prepared from spleens excised from mice A to K after the breeding test for 10 weeks were respectively stimulated with anti-CD3 antibody or LPS according to a conventional method. , IL-1β, IL-2, IL-4, IL-6, IL-10, or IFN-γ production was induced, and the amount of cytokines produced by spleen cells derived from each group of mice was measured.

  As a result, when spleen cells were stimulated with an anti-CD3 antibody, the production amount of IL-2, which is a T cell growth factor and involved in allergic diseases, was determined as follows. No significant difference was observed between mice A and J fed 10 (see FIG. 1).

  The production amount of IL-4 having an allergic effect is as follows: a group K mouse fed with control water, and a group A, group B, group G and J mice fed test water 1, 2, 7 or 10 There was no significant difference between the two. However, the amount of IL-4 produced by the group B mice fed with the test water 2 showed a “decrease tendency” compared to the group K mice fed with the control water. On the other hand, all of the B to F group, H group and I group mice fed with test water 3 to 6, 8 or 9 showed “significant” IL-4 production compared to the K group mice fed with control water. (Refer to the “Result” column in FIG. 2 and Table 2).

  The production of IFN-γ, an inflammatory cytokine, was significantly different between group K mice fed with control water and group A to J mice fed either test water 1 to 10. None (see FIG. 3).

  In addition, when spleen cells were stimulated with LPS, the production amounts of IL-1β and IL-6, which are inflammatory cytokines, were ingested in group K mice ingested with control water and test water 1, 2, 7 or 10. No significant difference was observed among the A group, B group, G group and J group mice. However, the production amounts of IL-1β and IL-6 of the B group mice fed with the test water 2 both showed a “decrease tendency” compared to the K group mice fed with the control water. On the other hand, the B to F group, the H group and the I group mice fed with the test water 3 to 6, 8 or 9 all had IL-1β and IL-6 compared to the K group mice fed the control water. All of the production amounts were “significantly reduced” (see the “Result” column in FIGS. 4 and 5 and Table 2).

  Furthermore, the production amount of IL-10, which is an anti-inflammatory cytokine, was measured in group K mice fed with control water, group A, group B, group G and group J fed test water 1, 2, 7 or 10. There was no significant difference between mice. However, the IL-10 production amount of the group B mice fed with the test water 2 showed an “increase tendency” compared to the group K mice fed with the control water. On the other hand, all of the B to F group, the H group and the I group mice fed with the test water 3 to 6, 8 or 9 had an IL-10 production amount as compared with the K group mice fed with the control water. “Significantly increased” (see FIG. 6 and the “Result” column in Table 2).

(5) Summary From the results shown in the above (1) to (4), in animal experiments using mice, test water 2 to 6, 8, or 9 is human atopic dermatitis-like symptoms and human atopic skin The action of inhibiting or improving the thickening of the epidermis layer, which was observed when flaky symptoms appeared, was observed. This inhibitory action is caused by the production amount of IL-4 having an allergic enhancing action, IL-, which is an inflammatory cytokine, in the B to F group, the H group and the I group mice fed with the test water 2 to 6, 8 or 9. Both 1β and IL-6 production were “decreasing” or “significantly decreased”, and IL-10 production, an anti-inflammatory cytokine, was “increased” or “significantly increased” Therefore, all of test water 2 to 6, 8 and 9 are dominant helper T (Th) 2 cells (known as cytokine producing cells such as IL-4) involved in the pathogenesis of human atopic dermatitis. It is judged that the immune response was improved and the result was achieved. Further, in view of the behavior of various cytokines in the B to F group, the H group and the I group mice fed with the test water 2 to 6, 8 or 9, the test waters 2 to 6, 8 and 9 are human atopic skin. It is judged to have an action of suppressing or improving not only the flame but also the inflammatory reaction caused by infection with bacteria and the like.

  From the results of this experiment, the mineral ion composition containing mineral ions such that the calcium ion concentration is less than 200 ng / ml and the magnesium ion concentration is 50 ng / ml or more and less than 2,500 ng / ml, especially calcium ions. The concentration is less than 200 ng / ml, the magnesium ion concentration is 50 ng / ml or more and less than 2,500 ng / ml, and the other mineral ion is one or two selected from potassium ion, manganese ion, iron ion, and zinc ion Mineral-adjusted water containing a total of 50 ng / ml or more and less than 1,000 ng / ml of mineral ions of at least species has an effect of effectively suppressing or improving human atopic dermatitis, and is caused by infection with bacteria, etc. Has the effect of suppressing or improving the inflammatory response It is determined to be.
