Description

本発明は、健康補助食品などとして簡便に摂取可能な血栓性疾患予防食品、より詳細には特定の微生物による発酵物を有効成分として含む血栓性疾患予防食品に関する。   The present invention relates to a thrombotic disease preventive food that can be easily ingested as a health supplement, and more particularly to a thrombotic disease preventive food containing a fermented product of a specific microorganism as an active ingredient.

厚生労働省発表の傷病分類別の診療医療費をみると、高血圧性疾患、虚血性疾患および脳血管疾患からなる循環器系の疾患の診療医療費が一番多く、診療医療費全体の21.2%を占めている。そして、これらの疾患はいずれも血管における血栓の異常な形成が関与している。   Looking at the medical care costs by injury and illness classification announced by the Ministry of Health, Labor and Welfare, the medical care costs for cardiovascular diseases consisting of hypertensive diseases, ischemic diseases and cerebrovascular diseases are the largest, accounting for 21.2% of the total medical costs is occupying. All of these diseases involve abnormal formation of blood clots in blood vessels.

血液には凝固系と線溶系の2つの作用がある。血管壁が損傷すると血小板が凝集し、一次止血が起こり、その後凝固系因子であるトロンビンは血中フィブリノーゲンに働くことでフィブリンが形成され止血が完了する。一方、このように血管内で形成されたフィブリンを血管内皮細胞から分泌される線溶系因子である組織プラスミノーゲンアクチベーター(tPA)が血中に存在する酵素源であるプラスミノーゲンをプラスミンに変換し、そのプラスミンがフィブリンを分解する。凝固系と線溶系のバランスの破綻は脳梗塞や心筋梗塞などの血栓性疾患の原因となることが知られており、新たな線溶系亢進物質の開発はこれらの疾患の予防・治療に大きく貢献し得ると考えられる。   Blood has two actions: a coagulation system and a fibrinolytic system. When the blood vessel wall is damaged, platelets aggregate and primary hemostasis occurs, and then thrombin, a coagulation factor, acts on blood fibrinogen to form fibrin and complete hemostasis. On the other hand, tissue plasminogen activator (tPA), which is a fibrinolytic factor secreted from vascular endothelial cells, is converted into plasmin. Converts and the plasmin degrades fibrin. Failure of the balance between coagulation and fibrinolytic systems is known to cause thrombotic diseases such as cerebral infarction and myocardial infarction, and the development of new fibrinolytic substances greatly contributes to the prevention and treatment of these diseases It is considered possible.

本発明者らは、納豆菌類を培養することにより産出される酵素や微量成分を安定した状態にまで可逆的に低分子化した物質に関する製法の特許権(特許文献1)を取得している。   The present inventors have obtained a patent right (Patent Document 1) for a production method relating to a substance in which an enzyme and a trace component produced by culturing natto fungi are reversibly reduced to a stable state.

バチルス・ズブチリスAK菌株は、所望により乳酸菌を含む他の発酵菌と共に、上記した発酵用培地上、約4.5〜6.5のpH、約28〜32℃の条件で2ヶ月以上発酵する。これらの領域より低いpH域や温度域では、2ヶ月以上発酵させても、この発明に用いる所定の納豆菌が効率よく糖および窒素源を資化しないと推定され、得られるtPA放出亢進物質に所期した効果が充分得られない。一方、上記の領域より高いpH域や温度域では、発酵不充分で所定の納豆菌が効率よく糖および窒素源を資化せず、得られるtPA放出亢進物質に所期した効果が充分得られない。   The Bacillus subtilis AK strain is fermented for two months or longer on the above-mentioned fermentation medium with a pH of about 4.5 to 6.5 and a temperature of about 28 to 32 ° C. together with other fermenting bacteria including lactic acid bacteria if desired. In the pH range and temperature range lower than these ranges, it is estimated that the predetermined Bacillus natto used in this invention does not efficiently assimilate the sugar and nitrogen sources even when fermented for 2 months or more. The desired effect cannot be obtained sufficiently. On the other hand, in a pH range or temperature range higher than the above range, the desired effect of the tPA release-enhancing substance can be sufficiently obtained because the predetermined Bacillus natto does not efficiently assimilate the sugar and nitrogen sources. Absent.

発酵につづいて、菌類は、同培地上、約4.0〜6.0のpH、約13〜17℃の条件で4ヶ月以上熟成する。これらの領域より低いpH域や温度域では、4ヶ月以上熟成させても、発酵生産物として各種の活性を有するアミノ酸、リポ蛋白、リポ多糖(リポポリサッカライド)、リピッドなどが充分に低分子量化しないと推定され、得られるtPA放出亢進物質に所期した効果が充分得られない。一方、上記の領域より高いpH域や温度域では、活性が低下すると推定され、得られるtPA放出亢進物質に上記同様に所期した効果が充分得られない。   Following the fermentation, the fungi are aged on the same medium at a pH of about 4.0 to 6.0 and a condition of about 13 to 17 ° C. for 4 months or longer. In the pH and temperature ranges lower than these ranges, amino acids, lipoproteins, lipopolysaccharides (lipopolysaccharides), lipids, etc. that have various activities as fermentation products are sufficiently low in molecular weight even after aging for 4 months or longer. The expected effect of the obtained tPA release enhancing substance is not sufficiently obtained. On the other hand, in the pH range and temperature range higher than the above range, the activity is estimated to decrease, and the obtained tPA release-enhancing substance cannot sufficiently obtain the expected effect as described above.

発酵および熟成段階を経て生成した液状成分を分取するには、濾過または遠心分離など周知の分離手段を採用することができ、分取した食品用原液は、そのまま、または濃縮もしくは希釈して本発明の血栓性疾患予防食品の有効成分として使用することができる。

因みに、このようにして得られる有効成分の構成成分としては、生体内酵素合成を容易にするための物質、すなわち発酵によって得られる酵素を可逆的に切断して活性アミノ酸残基としたフラグメントを含み、その他にアデニン、グアニン、シトシン、チミン、ウラシルのような生体内で活用できる有用物質を含有する。このような有用物質は、ベスレッカ(Besredka)の提唱したアンチビールスの組織活性因子、フィラトフ(Filatov)の説明する生命源刺激素を含み、これらを生物化学的反応によって組み合わせ、安全かつ有効に作用するように処理した培養濾液であると考えられる。   Incidentally, the components of the active ingredient thus obtained include substances for facilitating in vivo enzyme synthesis, that is, fragments obtained by reversibly cleaving the enzyme obtained by fermentation into active amino acid residues. In addition, it contains useful substances that can be used in vivo, such as adenine, guanine, cytosine, thymine, and uracil. Such useful substances include the anti-viral tissue active factor advocated by Besredka, the life-source stimulant described by Filatov, and combine these by biochemical reactions to act safely and effectively. It is considered that the culture filtrate was treated as described above.
