Description

口腔内菌叢改善剤及び口腔用組成物Oral flora-improving agent and oral composition
 本発明は、口腔内の病原性細菌の生育を抑制し、かつ非病原性細菌の生育を促進し、菌叢バランスを改善する口腔内菌叢改善剤及びこれを含有する口腔用組成物に関する。 The present invention relates to an oral flora improving agent that suppresses the growth of pathogenic bacteria in the oral cavity, promotes the growth of non-pathogenic bacteria, and improves the bacterial flora balance, and an oral composition containing the same.
 ヒトの口腔内には様々な細菌が共生しており、細菌叢と呼ばれる細菌集団を形成している。この細菌叢には、いわゆる非病原性の常在菌と、病原性を示す細菌とが混在しているが、通常は細菌叢のバランスが保たれている、いわゆる健康な状態であり、病原性細菌を原因とする疾患は抑制されている。 A variety of bacteria coexist in the human oral cavity, forming a bacterial population called the bacterial flora. This bacterial flora is a mixture of so-called non-pathogenic resident bacteria and pathogenic bacteria, but it is a so-called healthy state in which the bacterial flora is usually balanced, and pathogenicity Diseases caused by bacteria are suppressed.
 しかし、食生活や抗生剤の摂取、ストレス、加齢、清掃不良などが原因となって細菌叢のバランスが崩れると、病原性を有する病原菌や日和見感染菌が増加し疾患となる。このため、疾患の制御には、病原性細菌を抑制するだけではなく、非病原性の常在菌との細菌叢バランスを健康な状態に保つことが重要である。 However, if the balance of the bacterial flora is lost due to dietary habits, antibiotic intake, stress, aging, poor cleaning, etc., pathogenic pathogenic bacteria and opportunistic infections increase and become diseases. For this reason, it is important for disease control not only to suppress pathogenic bacteria but also to maintain a healthy bacterial flora balance with non-pathogenic resident bacteria.
 口腔内に生育する数百種類もの細菌の中で、病原性を示す細菌は、歯周病や口臭の原因菌であるポルフィロモナス ジンジバリス(Porphyromonas gingivalis)、プレボテラ インターメディア(Prevotella intermedia)、フゾバクテリウム ヌクレアタム(Fusobacterium nucleatum)、う蝕の原因菌であるストレプトコッカス ミュータンス(Streptococcus mutans)を代表とする数種類の細菌に過ぎない。残りのほとんどは、通常、ヒトへの病原性を示さないストレプトコッカス ゴルドニアイ(Streptococcus gordonii)、ストレプトコッカス ミティス(Streptococcus mitis)、ストレプトコッカス オラリス(Streptococcus oralis)を代表とするミティス(Mitis)グループなどのストレプトコッカス(連鎖球菌)属細菌や、ナイセリア サブフラバ(Neisseria subflaba)等のナイセリア属細菌、アクチノマイセス ビスコーサス(Actinomyces viscosus)等のアクチノマイセス属細菌等の非病原性の常在菌である。
 従って、口腔疾患の予防には、口腔内において、これら非病原性の常在菌からなる細菌叢をバランス良く健康な状態に維持、形成することが重要となる。
Among the hundreds of types of bacteria that grow in the oral cavity, the pathogenic bacteria are Porphyromonas gingivalis, Prevotella intermedia, and Fuzobacterium nucleatum, which cause periodontal disease and bad breath. (Fusobacterium nucleatum), there are only several types of bacteria represented by Streptococcus mutans, which is a causative bacterium of caries. Most of the rest are Streptococcus gordonii, Streptococcus mitis, Streptococcus oralis, and M. streptococcus oralis, which are representative of the mitochondrion of M. ) Genus bacteria, Neisseria subflava and other Neisseria bacteria, Actinomyces viscosus and other non-pathogenic bacteria such as Actinomyces viscosus.
Therefore, for the prevention of oral diseases, it is important to maintain and form a well-balanced and healthy state of the bacterial flora composed of these non-pathogenic resident bacteria in the oral cavity.
 しかしながら、口腔用組成物において、病原性細菌に対する殺菌力に優れたものは数多く報告されている一方で、上記のように非病原性細菌に着目し、口腔内細菌叢のバランス制御効果に優れたものは数少ない。プレバイオティクスに着目し、特定乳酸菌を有効成分とする口腔疾患の予防又は治療剤(特許文献1:特許第5982376号公報)、シソ属植物を含む植物等によるプレバイオティクス技術(特許文献2:特許第6235138号公報)、カフェインを用いて口腔細菌叢を改善する技術(特許文献3;特開2012-77053号公報)等が提案されているが、これら技術による効果は、口腔内細菌叢のバランス制御の点では十分ではなかった。
 また、口腔内細菌叢のバランス保持に関する技術として、プテロスチルベンや、カンカニクジュヨウ等の植物抽出物を用いた口腔用抗菌剤(特許文献4、5:特開2017-81831号公報、特開2016-113460号公報)、ヤマブシタケ等のキノコの乾燥粉末又はその抽出物を用いた口腔内の菌叢改善剤(特許文献6:国際公開第2016/043103号)が提案されている。
However, many oral compositions with excellent bactericidal activity against pathogenic bacteria have been reported. On the other hand, focusing on non-pathogenic bacteria as described above, the oral bacterial flora has an excellent balance control effect. There are few things. Paying attention to prebiotics, preventive or therapeutic agents for oral diseases containing specific lactic acid bacteria as active ingredients (Patent Document 1: Japanese Patent No. 598376), prebiotic technology using plants including perilla plants (Patent Document 2: Patent No. 6235138), techniques for improving oral bacterial flora using caffeine (Patent Document 3; JP 2012-77053 A), and the like have been proposed. The balance control was not enough.
In addition, as a technique for maintaining the balance of oral bacterial flora, antibacterial agents for oral cavity using plant extracts such as pterostilbene and kankanikujuyo (Patent Documents 4 and 5: JP-A-2017-81831, JP-A-2003-18381) No. 2016-113460), an oral flora improving agent (patent document 6: International Publication No. 2016/043103) using a dry powder of mushrooms such as Yamabushitake or an extract thereof has been proposed.

 本発明は、上記事情に鑑みなされたもので、口腔内の病原性細菌、特に歯周病や口臭の原因となる病原性細菌の生育を抑制し、かつ非病原性細菌の生育を促進し、菌叢バランスを改善する口腔内菌叢改善剤及びこれを含有する口腔用組成物を提供することを目的とする。 The present invention has been made in view of the above circumstances, and suppresses the growth of pathogenic bacteria in the oral cavity, particularly the pathogenic bacteria that cause periodontal disease and bad breath, and promotes the growth of non-pathogenic bacteria, It is an object of the present invention to provide an oral flora improving agent that improves the bacterial flora balance and an oral composition containing the same.
 本発明者らは、上記目的を達成するため鋭意検討を行った結果、スペルミン、スペルミジン、シアル酸又はラクトフェリンと、特定の糖類とを併用すると、口腔内の病原性細菌の生育を選択的に抑制し、かつ非病原性細菌の生育を選択的に促進し、口腔内の細菌叢バランスを非病原性の常在菌主体に改善する優れた菌叢改善作用を奏すること、更に、上記併用系を口腔内菌叢改善の有効成分として口腔用組成物に配合することで、優れた菌叢改善効果を付与できることを見出し、本発明をなすに至った。 As a result of intensive studies to achieve the above object, the present inventors selectively suppress the growth of pathogenic bacteria in the oral cavity when spermine, spermidine, sialic acid or lactoferrin is used in combination with a specific saccharide. And selectively promoting the growth of non-pathogenic bacteria, improving the bacterial flora balance in the oral cavity mainly to non-pathogenic resident bacteria, It has been found that an excellent effect of improving the flora can be imparted by blending it into the composition for oral cavity as an active ingredient for improving the oral flora.
 本発明では、(A)スペルミン、スペルミジン、シアル酸及びラクトフェリンから選ばれる1種以上と、(B)ラクチュロース、オリゴ糖及びシアル酸含有二糖から選ばれる1種以上の糖類とを併用すると、(A)成分が、口腔内の非病原性細菌の生育を抑制することなく病原性細菌の生育を選択的に抑制し、同時に(B)成分が、病原性細菌の生育を促進することなく非病原性常在菌の生育を選択的に促進するという、特異的な作用を奏した。この場合、(A)及び(B)成分の併用系によって、病原性細菌であるフゾバクテリウム ヌクレアタム(Fusobacterium nucleatum)、プレボテラ インターメディア(Prevotella intermedia)、ポルフィロモナス ジンジバリス(Porphyromonas gingivalis)の生育を選択的に抑制し、口腔内に常在する非病原性細菌、特にストレプトコッカス ゴルドニアイ(Streptococcus gordonii)等のストレプトコッカス属細菌、アクチノマイセス ビスコーサス(Actinomyces viscosus)の生育を選択的に促進し、これにより、非病原性細菌の存在割合を増やして細菌構成比のバランスを非病原性細菌主体に改善することができた。従って、本発明によれば、口腔内の細菌叢を非病原性の常在菌主体に改善することで、歯周病や口臭を予防することができる。
 後述の比較例にも示すように(A)成分には菌叢改善効果がほとんど認められず、(B)成分にも菌叢改善効果がほとんど認められなかったが、本発明では、(A)及び(B)成分を併用すると、非病原性細菌の存在割合が増えて細菌構成比を改善する優れた菌叢改善効果を奏し、格別顕著な作用効果を特異的に付与することができた(後述の実施例参照)。
In the present invention, when (A) one or more selected from spermine, spermidine, sialic acid and lactoferrin and (B) one or more saccharides selected from lactulose, oligosaccharide and sialic acid-containing disaccharide are used together, A) component selectively inhibits the growth of pathogenic bacteria without inhibiting the growth of non-pathogenic bacteria in the oral cavity, and at the same time, component (B) is non-pathogenic without promoting the growth of pathogenic bacteria. It exhibited a specific effect of selectively promoting the growth of the sexually resident bacteria. In this case, the pathogenic bacteria Fusobacterium nucleatum, Prevotella intermedia, and Porphyromonas gingivalis can be selectively grown by the combined system of the components (A) and (B). Inhibiting and selectively promoting the growth of non-pathogenic bacteria resident in the oral cavity, in particular, Streptococcus gordonii and other Actinomyces viscosus, and thereby non-pathogenic By increasing the abundance of bacteria, it was possible to improve the balance of the bacterial composition ratio mainly to non-pathogenic bacteria. Therefore, according to the present invention, periodontal disease and bad breath can be prevented by improving the bacterial flora in the oral cavity to be mainly non-pathogenic resident bacteria.
As shown in the comparative examples described later, the (A) component hardly recognized the flora improvement effect, and the (B) component hardly recognized the flora improvement effect. And when the component (B) is used in combination, the abundance ratio of non-pathogenic bacteria is increased, and an excellent flora improving effect that improves the bacterial composition ratio is achieved, and a particularly remarkable action effect can be specifically imparted ( (See Examples below).

Evaluation of Bacterial Composition Ratio of Biofilm 0.5 mL each of the evaluation samples was added to a 24-well multiplate (manufactured by Sumitomo Bakelite Co., Ltd.). As a control, 0.5 mL of purified water was added instead of the evaluation sample. Subsequently, 0.5 mL of the mixed bacterial solution was inoculated and anaerobically cultured at 37 ° C. for 24 hours to form a biofilm on the bottom of the plate. Then, after washing 4 times with 1 mL of phosphate buffered saline PBS, 1 mL of PBS was added again, and the biofilm was scraped off at the tip of the chip. The biofilm was dispersed by sonication (200 μA, 10 seconds), and a 10-fold dilution series was prepared using tryptic soy broth (manufactured by Tryptic Soy Broth, Becton and Dickinson). 50 μL each of the 10 −3 , 10 −4 , and 10 −5 dilutions are smeared onto a selective medium on which each bacterium is selectively grown, and after culturing, the number of bacterial colonies that grow is counted. The number of bacteria and the bacterial composition ratio were calculated.
