Description

A kind of preparation method of seed of Arillus Longan extract and application
The application is the Chinese invention patent application (applying date: on July 8th, 2009; Application number: 200980160302.2; Denomination of invention: a kind of preparation method of seed of Arillus Longan extract and application) divisional application.
Technical field
The present invention relates to a kind of preparation method of seed of Arillus Longan extract, gained seed of Arillus Longan extract is applied to organism and has anti-inflammatory, reduce the concentration of uric acid in blood, promote the growth of skin keratinocytes, strengthen the multiple efficacies such as wound healing machine turns and anti-microbial is active.
Background technology
One, inflammation (Inflammation):
Inflammation is a kind of very important phenomenon in Drug therapy, and for human body, it is the warning message before generating disease.When tissue is injured, no matter caused by antibacterial, wound, chemical substance or other reason, macrophage (Macrophage) near wounded tissue can be carried out the task of engulfing foreign substance by activating, and also can discharge some factors to start more further defense reaction simultaneously; If Inflamed tissue continues to stimulate by foreign substance, its defence machine turns can reach even several years several months, therefore when being in inflammatory status, the factor content discharged is often more.Confirm after deliberation: the described factor includes: nitric oxide (Nitric oxide, NO), neoplasm necrosis factor (Tumor necrosis factor, TNF), the white element of cell circle (Interleukin, IL), granule white blood cell clusters G-CSF (Granulocyte colony stimulating factor, G-CSF), monocyte colony stimulating factor (Monocyte colony stimulating factor, M-CSF), granule leukocyte and monocyte colony stimulating factor (Granulocyte-monocyte colony stimulating factor, GM-CSF), the TNF called after TNF-α that scholar will be produced by mononuclear cell and macrophage, by the lymphotoxin (Lymphotoxin that T lymphocyte produces, LT) called after TNF-β is distinguished.
Lipopolysaccharide (Lipopolysaccharides, LPS) is endotoxic Main Ingredients and Appearance, proves via zoopery: it is emptying that LPS can delay stomach, this effect and LPS induce time pro-inflammatory cytokines and nitric oxide production rising relevant.After body is subject to the stimulation of LPS, the cytokine profiles such as mononuclear phagocyte system synthesis TNF-α, IL-1 β, IL-6 can be triggered, participate in body defenses reaction and repair.The synthesis of these three kinds of cytokines of TNF-α, IL-1 β, IL-6 is orderly cascades, and namely LPS induces the synthesis of TNF-α, TNF-α induces the synthesis of IL-1 β and IL-1 β induces the synthesis of IL-6.But excessive cytokine also can produce ill effect to body, such as excessive TNF-α can cause multiple Organ Failure, disseminated inravascular coagulation and toxic shock, even cause death, the animal of applying TNF antibody then can stop the generation of lethal endotoxin shock effectively.
The anti-inflammatory drug that uses of the world of medicine is of a great variety now, such as antibiotic (Antibiotics), on-steroidal anti-inflammatory medicine (Non-steroidal anti-inflammation drugs; NSAIDs), anti-ly organize ammonia medicine (Anti-histamine drugs) etc., though have quite good antiinflammation, have the side effect such as Drug resistance and damage the intestines and stomach.
Two, gout:
Gout is purine metabolic disturbance or a kind of disease caused by underexcretion; its clinical characters is the acute single arthritis (Recurrent acute monoarthritis), Monosodium urate salt formation tophus (Tophi) deposition, chronic gout stone arthritis etc. of hyperuricemia (Hyperuricemia), recurrent exerbation; if without suitable treatment, gouty nephropathy (Gouty nephropathy) usually finally can be developed into.Primary disease is mainly divided into constitutional and the large class of Secondary cases two, nearly 1% patient is had caused by enzyme defect in primary gout patient, and most of etiology unknown, clinical take gouty arthritis as main manifestations, and normal with high fat of blood, hypertension, diabetes, arteriosclerosis and coronary heart disease etc.; Secondary gout is often caused by reasons such as nephropathy, hematopathy and medicines, and gout is its complication.
Hyperuricemia is the most important biochemical basis of gout, but be not the synonym of gout, research is pointed out: about have the Patients with Hyperuricemia of 5 ~ 18.8% finally can develop into gout, but patient with gout certain one-phase in its course of disease will have the existence of hyperuricemia.
Laboratory can utilize urinary acidification (Uricase differential spectrophotometric method) Accurate Measurement Level of Serum Uric Acid.Hyperuricemia can be divided into absoluteness and the large class of relative property two.Prescribe a time limit when uric acid concentration in blood exceedes the upper of solubility, be called absoluteness hyperuricemia, 37 DEG C time, in blood, uric acid saturation value is 7mg/dl, exceedes this saturation point, has acicular crystal to separate out gradually.With normal person's blood uric acid meansigma methods, general epidemiological study then adds that two standard deviations are for the upper limit, think that uric acid level in male's blood is more than 7mg/dl, when women is more than 6mg/dl, is called relative property metabolic arthritis disease.If Level of Serum Uric Acid is more than 7mg/dl, then the incidence rate of gout or renal calculus will increase.
The clinical manifestation of gout is divided into four-stage: asymptomatic hyperuricemia (Asymptomatic hyperuricemia), experimental study (Acute gouty arthritis), intermission (Inter-critical gout), chronic gout stone arthritis (Chronic tophaceous gout).
The method that diagnosis gout is more correct is: extract joint fluid when experimental study shows effect, as found that there is the needle-like urate crystal (Monosodium urate crystal) engulfed by neutrophils, under polarizing microscope, present negativity two-fold light (Negative birefringent), be gout.Other common Clinical signs or lab testing: break out single redness and swelling of joints severe pain, the Effects of Colchicine In Treatings such as first toe, instep, ankle have specially good effect person or hyperuricemia person, only can be used as the reference of diagnosis gout.
Because primary gout lacks etiological treatment, therefore can not effect a radical cure.The object of clinical treatment is: the acute attack 1, controlling gouty arthritis in time; 2, long-term treatment hyperuricemia, the destruction of joint caused to prevent Monosodium urate mineralization and kidney damage.
Selection as uric acid resisting medicine: normal renal function or mild damage, when twenty-four-hour urine acid output is lower than 600mg, can uses and promote urate excretion medicine; Renal function be medium infringement (creatinine clearance rate < 35ml/ minute) or twenty-four-hour urine liquid uric acid obviously raises time, should use and suppress uricopoiesis thing.When blood uric acid obviously raises and tophus deposits in a large number, above two kinds of medicines can be share, to prevent gradual gouty complication.
Aforesaid promotion urate excretion medicine (Uricosuric agent) promotes urate excretion mainly through suppressing proximal tubular to the heavily absorption of uric acid.For the side effect preventing uric acid from causing kidney damage and renal calculus when kidney is discharged in a large number, all should from low dose, dosage gradually in 7 ~ 10 days, and consider salinize urine.This quasi drugs has different (Probenecid) benzbromarone (Benzbromarone) of the third sulphur etc.
Aforesaid suppression uricopoiesis medicine (Xanthine oxidase inhibitor), only there is allopurinol (Allopurinol), its similar hypoxanthine (hypoxanthine), there is the effect of stronger suppression xanthine oxidase (xanthine oxidase), the formation of tophus and renal calculus can be suppressed, and promote tophaceous dissolving.When using anticarcinogen as mercaptopurine (Mercaptopurine) or azathioprine (Azathioprine), the blood level of anticarcinogen can be improved simultaneously, now need to consider or pay attention to clinical side effects.
Three, wound healing (Wound healing):
Wound healing is a kind of dynamic (Dynamic) many cell reciprocal actions (Interactive) and is multi-step (Multiple steps) process, comprises signaling, hyperplasia, cell differentiation, the synthesis of extracellular matrix and organization restructuring (Tissue remodeling) etc.This process is relevant with the regeneration of wound epidermis and the reparation of subcutaneous connective tissue.In the process of skin wound healing, the horn cell meeting hypertrophy at epidermis edge, wound both sides, and move in the middle of wound and form new epidermal area, these processes need even a few weeks longer just can complete in several days.
The somatomedin (Growth factors) of substantial connection is had with wound healing, include FGF2 (Fibroblast growth factor 2, FGF2), platelet derived growth factor (Platelet-derive growth factor, PDGF), epidermal growth factor (Epidermal growth factor, EGF), keratinocyte growth factor (Keratinocyte growth factor, KGF), transforminggrowthfactor-α (Transforming growth factor-α, TGF-α), transforming growth factor-β (Transforming growth factor-β, TGF-β) and VEGF (Vascular endothelial growth factor, VEGF).In these somatomedin (Growth factors), PDGF, EGF, TGF-β and VEGF is secreted by horn cell.Wherein, PDGF can attract macrophage (Macrophages) and fibroblast (Fibroblasts), and promotes the manufacture of stromatin (Matrix protein); EGF can with the movement of the form of autocrine (Autocrine) promotion self and hypertrophy; TGF-β can promote the hypertrophy of fibroblast (Fibroblasts), signaling and angiogenesis, and will disengage in a large number at the initial stage of wound healing; VEGF then can promote deposition and the angiogenesis of vascular permeability, short revascularization substrate (Proangiogenic matrix), and can stimulate the movement of mononuclear cell (Monocyte).Shown by above result of study: the somatomedin (Growth factors) that these horn cells discharge is all closely related with wound healing process.
On the other hand, record according to " national Chinese herbal medicine compilation ": seed of Arillus Longan can be used for that treatment stomachache, burn and scald, knife injury are hemorrhage, infantile malnutrition pain due to disorder of QI, traumatic hemorrhage, scabies, eczema etc.Seed of Arillus Longan is used for the treatment of wound by ancients, has the effect of good hemostasis, analgesic therapy, granulation promoting." Huang Shi cures the side of destroying " is recorded: " control injury by sword or axe, Arillus Longan core is regardless of how many, by the withered sustainability of baked wheaten cake, grinds into powder, mixes affected part and namely heal ".Ancient documents is recorded: " former times succours the more people in Xiqin and the female army of Ba Li for seed of Arillus Longan end, deposit knife injury "." blackish red toe biography side " also cloud: " control knife injury hemorrhage, fry with seed of Arillus Longan and smash fine grinding, apply it ".Can be known by the record of above ancient book and pharmacopeia: seed of Arillus Longan has therapeutic effect to skin knife injury and relevant disease, to promoting that the healing of wound is effective, but its effect machine turns and unclear.
