Description
本発明は、ジンジバリス菌及び/又はミュータンス菌に起因する疾患の予防又は治療剤に関する。本発明は、より詳細には、アルツハイマー型認知症の予防又は治療剤に関する。 The present invention relates to a prophylactic or therapeutic agent for diseases caused by Porphyromonas gingivalis and / or Streptococcus mutans. The present invention, in more detail, relates to a prophylactic or therapeutic agent for Alzheimer's disease.
ポルフィロモナス・ジンバリス(Porphyromonas gingivalis。以下、「ジンジバリス菌」ともいう。)は、ヒトの口腔内に存在する細菌である。ジンジバリス菌は、重要な歯周病源細菌として知られているが、歯周病以外の疾患との関連も注目されている。例えば、非特許文献1では、ジンジバリス菌は、アルツハイマー病の脳における病原体の最有力候補の一つであり、アルツハイマー病を引き起こす一連の事象に関与している可能性が指摘されている。また、ジンジバリス菌等の歯周細菌が心血管疾患発症の要因である可能性があること(非特許文献2)、及びジンジバリス菌による内皮細胞への侵入及び寄生がアテローム性動脈硬化症という炎症反応を悪化させる可能性があること(非特許文献3)も指摘されており、さらに、脳膿瘍からジンジバリス菌が検出され、口腔領域からの感染が強く疑われた事例(非特許文献4)も報告されている。 Porphyromonas gingivalis (hereinafter, also referred to as "Gingivalis bacterium") is a bacterium present in the human oral cavity. Porphyromonas gingivalis is known as an important source of periodontal disease, but its association with diseases other than periodontal disease has also attracted attention. For example, Non-Patent Document 1 points out that Porphyromonas gingivalis is one of the leading candidates for pathogens in the brain of Alzheimer's disease and may be involved in a series of events that cause Alzheimer's disease. In addition, periodontal bacteria such as Porphyromonas gingivalis may be a factor in the onset of cardiovascular disease (Non-Patent Document 2), and invasion and infestation of endothelial cells by Porphyromonas gingivalis is an inflammatory reaction called atherosclerosis. It has also been pointed out that there is a possibility of worsening the disease (Non-Patent Document 3), and a case in which Gingivalis bacteria were detected in a brain abscess and infection from the oral region was strongly suspected (Non-Patent Document 4) was also reported. Has been done.
また、ストレプトコッカス・ミュータンス(Streptococcus mutans。以下、「ミュータンス菌」ともいう。)も、人の口腔内に存在する細菌であり、虫歯(う歯)の代表的な原因菌として知られている。 In addition, Streptococcus mutans (hereinafter, also referred to as "mutans bacterium") is a bacterium existing in the human oral cavity and is known as a typical causative bacterium of dental caries (dental caries). ..
ジンジバリス菌及びミュータンス菌と様々な疾患との関連が指摘される中で、ジンジバリス菌及び/又はミュータンス菌に作用して、上記のような疾患を予防又は治療することのできる予防又は治療剤への需要が高まっている。これに対し、例えば、特許文献1には、粒度分布における最頻値が1.0μm以下である乳酸菌を有効成分として含有することを特徴とする口腔用組成物が、う蝕関連細菌のミュータンス菌や歯周病関連細菌のジンジバリス菌類に対して、選択的に作用を示し、それゆえ口腔内フローラを良い環境に導くことが記載されている。 While the association between Porphyromonas gingivalis and mutans and various diseases has been pointed out, a preventive or therapeutic agent capable of acting on porphyromonas gingivalis and / or mutans to prevent or treat the above-mentioned diseases. Demand for is increasing. On the other hand, for example, in Patent Document 1, the oral composition characterized by containing lactic acid bacteria having a most frequent value of 1.0 μm or less in the particle size distribution as an active ingredient is a mutans of caries-related bacteria. It has been described that it acts selectively on bacteria and periodontal disease-related bacteria, Streptococcus chinensis, and therefore leads to a favorable environment for the oral flora.
本発明は、新規なジンジバリス菌及び/又はミュータンス菌に起因する疾患の予防又は治療剤の提供を目的とする。 An object of the present invention is to provide a prophylactic or therapeutic agent for a disease caused by a novel Porphyromonas gingivalis and / or Streptococcus mutans.
本発明者らは、白金コロイドとパラジウムコロイドとを共に用いることでジンジバリス菌及び/又はミュータンス菌の増殖を抑制できることを見出し、本発明を完成するに至った。 The present inventors have found that the growth of gingivalis and / or mutans can be suppressed by using both platinum colloid and palladium colloid, and have completed the present invention.
すなわち、本発明は、以下の各発明に関する。
[1]白金コロイドとパラジウムコロイドとを含有する、ジンジバリス菌及び/又はミュータンス菌に起因する疾患の予防又は治療剤。
[2]疾患がアルツハイマー型認知症、歯周病、心血管疾患、アテローム性動脈硬化症、脳膿瘍、及び虫歯からなる群より選択される1種以上である、[1]に記載の予防又は治療剤。
[3]疾患がアルツハイマー型認知症である、[2]に記載の予防又は治療剤。
[4]疾患が歯周病である、[2]に記載の予防又は治療剤。
[5]疾患が脳膿瘍である、[2]に記載の予防又は治療剤。
[6]疾患が虫歯である、[2]に記載の予防又は治療剤。
[7]白金コロイドの濃度が0.08~16mMの液剤である、[1]~[6]のいずれかに記載の予防又は治療剤。
[8]パラジウムコロイドに対する白金コロイドのモル比が、1/30~10/1である、[1]~[7]のいずれかに記載の予防又は治療剤。
[9]パラジウムコロイドの濃度が0.1~30mMの液剤である、[1]~[8]のいずれかに記載の予防又は治療剤。

上記の検体10mlに試験菌液0.1mlを接種して試験液を作製し、室温で1分、3分、及び5分保存後の試験液中の生菌数を測定した。生菌数の測定は、5%馬脱繊維血液加Brucella Agar(BD BBL(登録商標))を用いた平板塗抹培養法(35℃±1℃、5~7日間嫌気培養)により行った。なお、生菌数の測定にあたり、検体の影響を受けずに生菌数の測定ができるように、試験液をSDCLP培地(日本製薬株式会社製)で10倍に希釈した。また、対照として、検体に変えて生理食塩水を用いて同様の試験を行った。結果を表1に示す。 A test solution was prepared by inoculating 10 ml of the above sample with 0.1 ml of the test bacterial solution, and the viable cell count in the test solution after storage at room temperature for 1 minute, 3 minutes, and 5 minutes was measured. The viable cell count was measured by a plate smear culture method (35 ° C ± 1 ° C, anaerobic culture for 5 to 7 days) using Brucella Agar (BD BBL (registered trademark)) with 5% horse defibered blood. In measuring the viable cell count, the test solution was diluted 10-fold with SDCLP medium (manufactured by Nihon Pharmaceutical Co., Ltd.) so that the viable cell count could be measured without being affected by the sample. In addition, as a control, a similar test was conducted using physiological saline instead of the sample. The results are shown in Table 1.
