Recall;Improve immune, rehabilitation body, promote growth, anti-aging.Increasingly fierce and rhythm of life with social competition adds
It hurry up, sleep-disorder or and relevant disease of sleeping occur in more and more people.Show according to investigations, sleep-disorder occurs in adult
Ratio up to 35%, sleep-disorder occurs in the elderly 57% of more than 60 years old, is slept in children within 2~6 years old in some cities
Dormancy obstacle accounts for 27%.In addition pregnant woman sleeps incidence up to 75% in pregnant latter stage of being pregnent.Some researches show that extended sleep is less than 5
Hour be able to can be easier to suffer from hypertension, diabetes, obesity, can also induce melancholia.Especially middle-aged and elderly people's sleep-disorder can lure
Send out nighttime sleep arrhythmia cordis, sudden death, palsy, pulmonary hypertension, twitch and decrease of cognitive function etc..
Sleep-disorder refers to that sleep quality is abnormal or occurs some clinical symptoms, and such as sleep reduces or hypersomnia,
Sleep associated dyskinesias etc., wherein most commonly seen to have a sleepless night.Sleep-disorder becomes worldwide disease, international mental hygiene and
Neuscience foundation was set up in 2001 established sleep medicine annual March 21 in succession for sleep day, countries in the world, into
Hypnosphy meeting is stood, and clearly sleep science is a comprehensive subject, including clinical sleep medicine, Sleep hygiene, has slept
Environmentology, sleep engineering science etc..
Sleep state one shows as eyes and rotates rapidly, that is, (shallow sleep, REM are slept famous fast REM sleep
Sleep), at this moment brain neopallium is rested, but cerebral limbic system's (diencephalon, midbrain, pon, oblongata) is in waking state, is carried out
Intracerebral information processing, remembers the work such as fixed;And another stage is then directly referred to as non-fast REM sleep (deep sleep, HREM
Sleep), at this moment body is fully rested, immune to be improved, and is played a decisive role to health.The sleep of a whole night is different journeys
What the multiple alternate repetition of shallow sleep and deep sleep of degree carried out.
Dormant startup and maintenance are related with numerous transmitter substances and hormone (also referred to as sleep substance) in vivo.
The sleep substance understood has tens of kinds, for example known melatonin (melatonin), melatonin are human brains
A kind of amine bormones of " pineal body " secretion, is a kind of hormone in vivo for inducing natural sleep, also has lateral hypothalamic region synthesis
Small molecule nerve polypeptide orexin (Orexin) of the secretion with effect of ingesting, and central nervous system impression transmit material
γ-aminobutyric acid (GABA), oxidized form of glutathione (GSSG) are also a kind of sleep property material, it is by suppressing excitatory neuron
Transmitter glutamate plays sedation.Internal sleep substance status level determines sleep quality substantially as can be seen here.
γ-aminobutyric acid (GABA) is a kind of active skull cap components, is distributed widely in animal and plant body.Plant such as Macroptilium,
Join in the seed, rhizome and tissue fluid of category, Chinese herbal medicine etc. and all contain GABA.In animal body, GABA almost exists only in nerve
In tissue, the content in its mesencephalic tissue is about 0.1-0.6mg/ grams of tissue, and immunological investigation shows, the highest area of its concentration
Domain is black substance in brain.GABA mainly has following physiological activity:1. calm nerve, antianxiety.2. blood pressure lowering.3. improve sleep,
Improve memory.4. prevent and treat the neurological diseases such as epilepsy.5. the effect of removing toxic substances.
GABA be by Pidolidone (Glu) or derivatives thereof under glutamic acid decarboxylase enzyme effect, take off what α-carboxyl was formed,
Therefore the reduction of content of glutamic acid may be considered the synthesis of GABA.The synthetic method of GABA mainly has chemical synthesis and biology
Synthetic method, chemical synthesis GABA are needed using stronger solvents of corrosivity such as strong acid and highly basic, and reaction condition is violent, material toxicity
Greatly, it is expensive and there are more safety issue.Therefore biological synthesis process, biosynthesis mainly are used in actual production
Method is mainly by way of fermentation, and the fermentation method of early stage is mainly with Escherichia coli (Escherichia coli) fermenting and producing
Based on GABA.Due to the consideration of food-safe property, saccharomycete, lactic acid bacteria and the Aspergillus of glutamate decarboxylase are gradually screened
Etc. food security level microbe come the GABA that ferments.
Microbial fermentation is for raw material, through multiple beneficial with one or more fresh vegetables, fruit, mushroom, Chinese herbal medicine etc.
What bacterium fermented and produced, the micro- life of the feature containing nutritional ingredients such as abundant vitamin, enzyme, mineral matter and secondary metabolites
Thing fermented product.Enzyme microb not only saves nutriment intrinsic in fermentation raw material, and has many active ingredients
Substantial increase, and generate some new bioactive ingredients and biology enzyme.
