Abstract

It has been demanded to develop pharmaceuticals, nutritional foods and the like which can improve the blood flowability in a person having poor blood flow to reduce the risk of occurrence of life-style related disease or the like or ameliorate the condition of the disease and consequently improve the quality of the life of the person. Thus, disclosed is a blood flowability-improving agent or an agent for prevention or amelioration of a disease that causes the decrease in blood flow. The agent comprises ornithine or a salt thereof as an active ingredient.

[0001] 本発明は、オル-チンまたはその塩を有効成分として含有する、血液流動性改善 剤および血液流動性が低下する疾患の予防または改善剤に関する。  [0001] The present invention relates to a blood fluidity-improving agent and an agent for preventing or improving a disease in which blood fluidity is lowered, comprising ortin or a salt thereof as an active ingredient.
背景技術  Background art
[0002] わが国の厚生労働省の調査による死亡統計では、虚血性心疾患、脳血管障害が 全死亡原因の約 30%を占め、癌に匹敵する。し力もこれらの疾患は、働き盛りの年 代に突然発症することが多ぐ社会的にも極めて損失が大きい。  According to the death statistics surveyed by the Ministry of Health, Labor and Welfare in Japan, ischemic heart disease and cerebrovascular disease account for approximately 30% of all causes of death and are comparable to cancer. However, these diseases are extremely lossy from a social point of view, since they often develop suddenly in the working years.
[0003] 虚血性心疾患や脳血管障害はいずれも循環器系の疾患であり、動脈硬化の進展 に伴い、血管内に血栓が形成すること等によって引き起こされる。最近、これらの疾 患を誘発する要因の 1つとして血液流動性の低下が指摘されている。血液流動性の 低下は血圧の上昇を招き、血管内皮に傷害を与えることによって血栓の形成を促進 する。食生活の欧米化や運動不足、過度のストレス等の生活習慣の悪ィ匕が血液流動 性の低下に深く関わって 、ると考えられて 、る。  [0003] Both ischemic heart diseases and cerebrovascular disorders are cardiovascular diseases, which are caused by the formation of thrombus in blood vessels as arteriosclerosis progresses. Recently, a decrease in blood fluidity has been pointed out as one of the factors inducing these diseases. Reduced blood fluidity increases blood pressure and promotes thrombus formation by damaging the vascular endothelium. It is thought that bad habits of lifestyle such as westernization of dietary life, lack of exercise, and excessive stress are deeply related to the decrease in blood fluidity.
[0004] これまでに、血液流動性を改善する可能性のある食品や食品素材が多数報告され ている。該食品としては、例えば梅干や黒酢等が知られている。また該食品素材とし ては、例えばフラバンジェノール (特許文献 1)、レモンポリフエノール (非特許文献 1) 、ダルコサミン (非特許文献 2)等が知られている。  [0004] So far, many foods and food materials that have the potential to improve blood fluidity have been reported. As the food, for example, plum dried or black vinegar is known. Further, as the food material, for example, flavangenol (patent document 1), lemon polyphenol (non-patent document 1), darcosamine (non-patent document 2) and the like are known.
[0005] オル-チンは、成長ホルモンを分泌させ筋肉合成を増強する、ある!/、は基礎代謝 を高め肥満を予防する食品素材として、米国を中心に用いられている。また、オル- チンは、欧州では肝臓障害を改善する医薬品として L-オル-チン L-ァスパラギン酸 塩の形態で用いられて 、る。  [0005] Orthin secretes growth hormone and enhances muscle synthesis, and there is! /, Which is used mainly in the United States as a food material to increase basal metabolism and prevent obesity. In Europe, ortin is used in the form of L-ortin L-aspartate as a pharmaceutical agent for improving liver damage in Europe.
[0006] オル-チンと代謝上近!、関係にあるアルギニンには血管拡張作用や血液流動性 改善作用等が報告されて 、る一方で、オル-チンはアルギニン不足を補う作用はな い (非特許文献 3)。また、オル-チンは、ヒト前腕で血管拡張作用を示さないことが 知られている (非特許文献 4)。 特許文献 1:特開 2005-97324号公報 [0006] Arginine, which is close in metabolism to ortin, has been reported to have vasodilatory effects and blood fluidity-improving effects, while ortin does not compensate for arginine deficiency ( Non-patent document 3). Ortin is known not to exhibit a vasodilatory effect on the human forearm (Non-patent Document 4). Patent Document 1: Japanese Patent Laid-Open No. 2005-97324
