Description

  The present invention relates to a safe and stable plasmalogen composition derived from a safe chicken, a food for improving cognitive function comprising the composition, and a method for determining its efficacy (clinical test method). More specifically, the present invention develops a plasmalogen composition (hereinafter sometimes referred to as “PLs”) having an effect of improving cognitive function and a food for improving cognitive function comprising the plasmalogen composition. Is intended. The biggest challenge is to demonstrate the effect of improving the cognitive functionality of the plasmalogen-added food for healthy individuals. Conventionally, clinical trials have been conducted exclusively to demonstrate the effectiveness of plasmalogen for patients with dementia, but the effects of improving the cognitive function have been limited, and are still at a practical level. The actual situation is far away (Non-Patent Documents 10 and 11, etc.).

  In recent years, plasmalogen has been attracting attention as a therapeutic and / or suppressive and preventive agent for neurodegenerative diseases and psychiatric disorders (for example, [Patent Document 1]). Plasmalogens are special phospholipids that are resident in vivo, have a vinyl ether bond in SN-1, and therefore have specificity for reducing properties. Although this plasmalogen is specific, it occupies 18% by mass of the total phospholipid in the living body, and it is no exaggeration to say that it is a kind of general-purpose phospholipid because of its content.

  This plasmalogen is functionally special in that it exhibits an important reducing action in vivo, but quantitatively, its location is localized in an important membrane in vivo, and various membranes It is not only having versatility because it directly protects against oxidative wear, but also has been revealed to express multifaceted functions especially in the brain. Is supposed to collect. However, as is apparent from the molecular structure, plasmalogens are easily oxidized by reversible reversal (radical scavenger and radical scavenging sensitivities) and highly hydrolyzable by hydration under acidic conditions (phospholipids). Of lyso form and aliphatic aldehyde). This is considered to be one of the causes that hinder the practical organic synthesis of plasmalogens.

  At present, plasmalogens rely exclusively on extraction and purification from biological tissues (for example, [Patent Document 2], [Patent Document 3], [Patent Document 4], etc.). In the living body, in view of its importance, stabilization is achieved by various appropriate mechanisms, and it is replenished by production from peroxisomes of biosynthetic systems, that is, endoplasmic reticulum.

  As a raw material for plasmalogen extraction, poultry, particularly spawning (also called egg collection) adult chickens are mainly used (for example, [Patent Document 1], [Patent Document 2], [Patent Document 3], [Patent Document 4]. Etc.), seafood-derived scallop viscera ([Patent Document 5] etc.) and aquaculture scallop viscera (eg [Patent Document 6]) have begun to be used. In the case of cultured bivalve molluscs, concerns about the venom accumulated from the environment, especially cadmium (safety concerns) cannot be wiped out.

  The most reasonable method for obtaining a safe, inexpensive and stable plasmalogen is through biological metabolism. The selection of the living body at that time is important. Laying spawning hens that have already been put to practical use for DHA hens, especially laying hens (laying hens that are thinned out due to a decrease in laying efficiency), more preferably forced molting (removing the fallen feathers by short-term fasting) Examples of laying laying hens by the poultry raising method for improving egg laying efficiency. In addition, the laying hen is literally a poultry whose purpose is to produce hen's eggs, and the same hen is a different poultry from a broiler for the purpose of meat collection. Due to the distribution of eggs, egg-laying chickens are roughly 1/10 as large as broilers (10 to tens of millions), and are raised in the vicinity of the consumption area.

  Usually, in this egg-laying chicken, the egg production is 300 or more per year, but the age at which the egg-laying efficiency is reduced is about 700 days. The slaughtered meat is processed at the private waste chicken processing centers (about 40 locations nationwide, with a processing capacity of several million to one million). The processed products are used for food, but most of them are distributed as low-cost chicken raw materials for processing in the form of mince etc., except for some. Spawning poultry has been forced to sell cheaply due to price competition with bulk imported frozen chicken, but it has been boosted by consumer safety in recent years, with added value as domestic chicken, and prices are rising However, economically, it cannot compete with the vertically integrated poultry farming with tens of millions of meat-only species, and it cannot compete with the texture of young birds (young chickens) that are only 50 days old in quality. The profitability of the egg-laying poultry industry continues to be sluggish.

  In the above situation, it should be noted that the average annual number of spawning hens has risen to 90 million, and the price for delivery to the poultry farm is generally low, for example, at 0 yen. That is. Furthermore, the accumulation degree of the generation | occurrence | production is high, and it is carried in as a live chicken to a waste chicken processing center, and the high freshness processing product comparable to a broiler is mentioned.

  The present invention is considered to be Alzheimer's disease (hereinafter referred to as “AD”), which is regarded as a globally intractable disease and is regarded as an urgent global challenge to be held up to the summit ([Non-Patent Document 1]) aimed at its cure. Is intended to put a stone on the conquest of dementia. Recently, most of chronic neurodegenerative diseases such as AD, Parkinson's disease, amyotrophic lateral sclerosis (hereinafter referred to as “ALS”), multiple sclerosis, or stroke or head It has become clear that acute brain injury such as trauma is accompanied by chronic inflammation of the central nervous system (brain, spinal cord, etc.).

  There is also a possibility that these diseases are caused by central inflammation and progress ([Non-Patent Document 2]). For example, it has been reported that central nervous system inflammation may cause neurodegenerative diseases such as Alzheimer's disease or cause the disease to progress (for example, [Non-Patent Document 2]). In addition, as a result of analyzing a rat model of memory impairment produced by intraperitoneal administration of LPS (lipopolysaccharide), a substance that causes inflammation, accumulation of Aβ (amyloid β) peptide was observed in the brain, It has been reported that the symptoms were recovered by a certain sulindac sulfide ([Non-patent Document 3]). Furthermore, it has become clear that central nervous system inflammation is observed at a high rate even in mental diseases such as depression and autism, developmental disorders, and even in normal aging processes.

  From the above, infection by preventing or treating central nervous system inflammation and related neuronal cell death ([Non-patent Document 4]), inhibition of neurogenesis ([Patent Document 2]) and accumulation in Aβ brain. Prevent neuronal damage and neuropathy caused by sexual inflammation, or treat neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease, or mental disorders and development such as schizophrenia, depression and autism It is expected that treatment of a disorder can be performed ([Non-Patent Document 3]). Under such circumstances, a method capable of treating central nervous system inflammation and the like effectively and without side effects is desired more than ever before.

  Plasmalogen, which is a resident general-purpose phospholipid in vivo, has a history in which a living tissue containing it has been conventionally edible. Therefore, it is considered that the plasmalogen according to the present invention (particularly plasmalogen extracted from a living body, especially chicken tissue) has almost no side effects and is extremely safe. However, once the plasmalogen is extracted and separated from the living tissue, the stability is lost and the vinyl ether bond is exposed to the risk of decomposition. This means that the [strongly reducible] vinyl ether bond is strong [easily oxidizable] (= “easy” oxidatively degradable), and some appropriate defensive measures must be taken to make effective use of it. Application is essential.

It can be used as a supplement ([Non-Patent Document 5]).

  Plasmalogen is a component that is abundant in biological tissues, and biological tissues containing plasmalogens have been used for food. Therefore, the food for improving cognitive function of the present invention containing plasmalogens (particularly plasmalogens extracted from living tissue) is almost free of side effects and the like as a supplement for alleviating and preventing brain dysfunction. Is considered to be an extremely high functional food.

3 shows questions for selection of subjects regarding cognitive function. An MMSE sheet is shown. A collection of questions for cognitive function diagnosis. The test result of MMSE is shown. The result of a UK test is shown.

Hereinafter, the present invention will be described in more detail.
The present invention relates to a safe and inexpensive plasmalogen, examination of its cognitive function improving action on humans, development of a food for improving cognitive function, and a method for determining its efficacy (clinical test method).

  Plasmalogen is a kind of ether phospholipid, and is a glycerophospholipid having a long-chain alkenyl group via a vinyl ether bond in SN-1, and is a general-purpose type that accounts for 18% by mass of phospholipid in vivo, but has strong reducing properties. It is a general term for special phospholipids. This peculiarity gives the plasmalogen remarkable oxidative degradability and hydrolyzability, and in practical use, it is a typical “twisting” phenomenon, and therefore a rational measure to break it is required. The inventors of the present invention have made it possible to safely handle the “antinomy” sexual event, that is, avoiding the method of “sharpening the horn and killing the cow”, while taking full advantage of the original functionality of the plasmalogen. The present invention has been established by succeeding in stabilization.

  As the plasmalogen used in the present invention, chicken (particularly breast), chicken skin, internal organs (particularly intestine, ovarian fallopian crown, sand liver), egg, gala (minc preparation byproduct), feathers, etc. are used. Is preferred. Peeled breast with a large amount of generation and long experience is particularly suitable.

  In the present invention, it is particularly preferable to use a plasmalogen extracted from chicken tissue as the plasmalogen extracted from living tissue. Among them, chickens that have been conventionally used for food are suitable because they have been confirmed to be safe and can be stably supplied. The method for extracting plasmalogen from a living tissue is not particularly limited as long as the plasmalogen can be extracted (and purified if necessary), but from the viewpoint of simplicity and cost, it is extracted and purified as described below. It is preferable. In addition, the extraction and purification method is preferable in that the diacyl glycerophospholipid can be decomposed and removed, and thus the purity of the plasmalogen can be further increased.

Specific examples of the plasmalogen extraction and purification step include the following steps 1) to 2).
1) A step of extracting and fractionating from a biological tissue into three phases: a total lipid fraction (including a low molecular weight water-soluble fraction), a protein fraction, and a neutral lipid fraction.
Specifically, the following steps 1) to 5) are exemplified.
(1) Mincing the living tissue and slowly freezing it,
(2) Frozen mince is sterilized by high-speed cooking with “overheated water” (Aquagas ^RTM ; [Patent Document 6], [Patent Document 7], [Patent Document 8], [Patent Document 9]) after pressing and dewatering. Vacuum high-speed cooling (cooling and dehydration in an oxygen-free atmosphere),
(3) After the dehydration treatment, a step of adding 3 times (V / W) amount of degassed (deoxygenated) ethanol and performing extraction by slowly stirring in a sealed anoxic atmosphere for 12 hours;
(4) The process of repeating the above,
(5) A step of combining ethanol, distilling off the ethanol in an oxygen-free atmosphere, and then centrifuging to separate the aqueous layer (water-soluble low molecular weight fraction) to obtain a total lipid fraction.
2) The enzyme is added to the complex lipid fraction to hydrolyze SN-1-linked fatty acids, and the mixed diacylglycerophospholipids are converted into lyso forms and extracted with a hydrophilic solvent together with by-product fatty acids to purify plasmalogens. Process.

  The extraction is preferably carried out with an organic solvent (for example, ethanol, acetone, hexane, etc. and those having food suitability such as at least two mixed solvents selected from the group consisting of these) or a water-containing organic solvent. Moreover, the chicken tissue to be subjected to extraction is preferably exemplified by a method of treating in the steps (1) and (2) above. That is, in order to minimize the amount of ethanol used in the subsequent three-phase fractionation with ethanol, it is required to perform deoiling and dehydration as much as possible from a living tissue in an oxygen-free atmosphere at low temperature and in a short time.

  As for the extraction treatment conditions, in order to minimize the oxidative decomposition and hydrolysis of the contained plasmalogen, it is to stir for a short time at a low temperature in a sealed oxygen-free atmosphere. As a suitable example, ethanol is added to the breast of the laying hen that has been treated in the above-described pretreatments (1) and (2), and the mixture is allowed to stand at 30 ° C. or higher and 50 ° C. or lower for 180 minutes or longer, or gently stirred. A method is illustrated. To 1 kg of the breast meat, 2 to 4 L of ethanol that has been degassed (deoxygenated) in advance is added and left still under sealing or slowly stirred.

  Among the three phases, the water-containing ethanol phase is obtained by evaporating and concentrating ethanol to separate the aqueous layer, and then adding hexane that has been degassed in advance to extract the phospholipid fraction. Combine the separated water layer and hexane insoluble layer, add degassed water, leave it at 4 ° C, and centrifuge at low temperature to remove the insoluble part. A fraction of 12 g is obtained. On the other hand, the hexane solution is evaporated to dryness by a conventional method to obtain 5.4 g of a complex lipid fraction.

  The phospholipid fraction can be subjected to an enzymatic hydrolysis treatment step to hydrolyze the diacyl phospholipid, so that plasmalogen can be preferably concentrated. Examples of such hydrolysis treatment include enzyme treatment with phospholipase A1 (hereinafter referred to as “PLA1”) ([Patent Document 4]). If treated with PLA1, the mixed diacyl glycerophospholipid is decomposed into free fatty acid and lysophospholipid, and if these are extracted and distributed with acetone and hexane, the plasmalogen can be purified. Removal of free fatty acids and lysophospholipids can be performed by partitioning with, for example, acetone and hexane.

  The origin of PLA1 is not particularly limited as long as the above effects can be obtained. For example, PLA1 derived from Aspergus oryzae can be mentioned. The PLA1 can be purchased from, for example, Mitsubishi Chemical Foods Corporation. The amount used can be appropriately set according to the amount of complex lipid obtained. Preferably, 0.2 to 200 units / mg of complex lipid can be used, and more preferably, 2 to 200 units / mg of complex lipid can be used. In addition, 1 unit is an amount that changes 1 μmol of substrate (complex lipid) per minute, and means 1 μmol / min.

  The buffer to be used can also be appropriately selected according to PLA1. For example, 0.1 M citrate-hydrochloric acid buffer (pH 4.5) can be used by dissolving 1 g of complex lipid in 1 to 30 ml, preferably 5 to 15 ml per 1 g of complex lipid, and adding a predetermined amount of PLA1. . The reaction is carried out in a nitrogen gas atmosphere using a degassed buffer for as short a time as possible, preferably for 1 hour, and at a temperature as low as possible, preferably at 50 ° C. with stirring as an enzyme reaction.

  Avoid enzyme deactivation treatment by heating. After the reaction is completed, immediately cool to room temperature, add 2 to 3 times the amount of hexane that has been degassed in advance, and centrifuge to collect the upper hexane layer. To remove the enzyme buffer and the enzyme protein. The hexane solution is distributed by appropriately adding acetone and water, and further, the solution is distributed by water or an aqueous solution to remove lysophospholipid and purify the plasmalogen. That is, neutral lipids other than phospholipids are removed with acetone, and plasmalogen and lysophospholipid are separated by aqueous solution partition. The plasmalogen derived from a biological tissue thus obtained can be preferably used as an active ingredient of a supplement for relieving and preventing the cognitive function for improving cognitive function of the present invention.

Preparation of complex lipids from waste chicken skinned breast meat Fresh peeled chicken breasts of egg-laying chickens that are chicken tissues were procured from a waste chicken processing center, and 1 kg of minced meat of about 8 mm was prepared. The mince was stored frozen slowly. In use, it was dehydrated and deoiled by pressing after forced thawing with warm running water. This was cooked with [superheated water] (Aqua gas; RTM) in an “anoxic atmosphere” (oxygen 0.5% by volume or less) for 5 minutes, and then subjected to rapid dehydration by a vacuum cooling method. The obtained dehydrated / deoiled / cooked / sterilized breast meat was subjected to a three-phase ethanol separation step after low-temperature grinding.

[Three-phase separation process]
The cooked and sterilized crushed breast meat obtained above is put in a container and degassed, and 800 ml of degassed ethanol is added to the container and sealed, and the mixture is slowly stirred at 35 ° C. for 10 hours. Thereafter, the mixture was allowed to stand under ice cooling to separate the upper layer chicken oil and the solid precipitated protein, thereby obtaining a water-containing ethanol fraction (sealed refrigerated storage). 800 ml of degassed ethanol was added to the protein, and the same extraction operation was repeated. The ethanol phase was separated by centrifugation, ice-cooled under sealing, and concentrated under reduced pressure. The solid content of the water-soluble low-molecular fraction was filtered off and evaporated to dryness under reduced pressure to obtain 7 g of plasmalogen-containing phospholipid (complex lipid).

(1) Fractionation of total lipid The total lipid extracted, distributed and separated by the Folch method was 1.8% by mass.
(2) Phospholipid profile assay Measurement was carried out by HPLC / ELSD method of Nana et al.

The difference between the measured values at 0, 6 and 12 weeks was statistically processed using the paired t test. The comparative evaluation of the measured values of the MMSE, UK test, and PSOL cognitive function self-diagnosis test within the same group was performed using the pair t test.

  Using the Student t test, intergroup comparisons were made between the measured values at 0, 6 and 12 weeks and the deviation from baseline (Δ0-6 weeks and Δ0-12 weeks). Background comparison of subjects within the group was performed using unidirectional square deviation analysis.

  This was not adjusted for fluctuations associated with the implementation period. Mislisted subjects were completely excluded from statistical processing. Statistical processing was performed using Statcell 4 and Excel statistics. The test statistical processing result between two samples was judged to be significant at <5%.

IV. Test results 1) Statistical information of subjects The ingestion test started by dividing 81 people into 3 wards, but 6 people dropped out. The reasons were: poor physical condition, sudden work convenience 3, housework convenience 1, and 75 people completed the test. The breakdown was test-1; 27 people, test-2; 23 people, placebo; 25 people, but there was no significant difference in age, sex and UK test (Table 3).

2) MMSE
The results are shown in FIG. A significant difference was observed in the group comparison between Test-1 and Test-2 at 12 weeks. In addition, at the 6th week, a significant difference was recognized in the group comparison in the placebo group. However, there was no significant difference between the groups, test-1 vs. placebo and test-2 vs. placebo.

3) UK test As shown in FIG. 5 and Table 4, no significant difference was observed in the three groups. However, in the comparison between groups, a trend of significant difference was observed between Test-1 at 6 weeks and placebo.

4) Self-diagnosis of cognitive function The results are shown in Tables 5 to 8. In the change contrast analysis between groups, Test-1 and Placebo,
In Test-2 and Placebo, there were significant differences between the following items:
# 1 (Test-1, Test-2), # 5 at 6th week
(Test-1), # 7 (Test-1, Test-2), # 8 (Test-1), # 12 (Test-1), # 13 (Test-1), # 17
(Test-1, Test-2), # 18 (Test-1), # 25 (Test-1), # 26 (Test-2), and # 27 (Test-1, Test-2)
On the other hand, in week 12, # 1 (Test-1), # 2
(Test-1, Test-2), # 4 (Test-1, Test-2), # 5 (Test-1, Test-2), # 8 (Test-1, Test-2),
# 12 (Test-1), # 15 (Test-2), # 16 (Test-2), # 17 (Test-2), # 20 (Test-2), # 21

In Test-2 vs. Placebo, the number of significant difference items 4 in the 6th week has increased significantly to 14 significant difference items in the 12th week.

5) Safety assessment As far as we can see in the daily report, there is no question that suggests any doubt about the safety of the test sample, and there is no problem with safety.

V. Evaluation of test results 1) General remarks It was confirmed that it was effective in improving cognitive functions related to language and status of healthy subjects who took plasmalogen-containing supplements for 12 weeks. Furthermore, the soft capsules under test did not cause any safety problems during the 12-week test period.

Although no significant difference was observed in the results of the UK test, a significant difference tendency was observed between the high-dose intake group and the placebo group at 6 weeks.
Results suggested a dose dependence between the high and low dose groups and a significant trend between them and the placebo group.
The dosage is very low for foods and supplements, especially “micron” order, which is considered to be less than the internal medicine, and it is 0.5mg or less per tablet. It is a surprising discovery that results were obtained in a short time and at 6 weeks suggesting an immediate improvement in computing power.

2) Detailed discussion (1) MMSE
Within the 0.5 mg group and the 0.25 mg group, a significant difference within the group was observed at 12 weeks. However, a significant difference within the group was found at 6 weeks in the placebo group.
(2) UK test Immediately, a significant difference trend was observed between the high-dose group and the placebo group at 6 weeks, and a dose-dependent trend was observed between the high-dose group and the low-dose group. It is worth noting.
(3) PSOL cognitive function self-diagnostic test From the 12th week and the 6th week, significant differences were observed within the high and low dose groups, between the groups, and between the placebo groups. There were significant differences between the high and low dose groups, but the results were not dose-dependent.

3) Summary evaluation * Random, double-blind, placebo-controlled trial,
* Using an innovative edible plasmalogen composition,
* For carefully selected healthy subjects (135 institutional registrants' document screening 135 ⇒ Cognitive function 3 level interview selection 81 ⇒ Examiner's interview selection 75 ⇒ Excludes ineligible persons found during the study 71)
* Extremely low daily doses, 0.5 and 1 mg, and
* Within an extremely short period of 12 weeks,
In only 6 weeks, a significant and immediate improvement effect of cognitive function was confirmed, which is evaluated as a surprising result.

The fairness of the judgment described above is IMPROVEMENT
