Description
Technical field
The present invention relates to a kind of preparation method of father-in-law's cloth extract, the father-in-law's cloth extract prepared with this method is also related to
Application, belong to Tibetan medicine field.
Background technique
Hyperuricemia (hyperuricemia) is one kind due to caused by purine metabolic disturbance and/or uric acid excretion disorder
Blood uric acid increases, and extracellular fluid lithate is in the disease of over-saturation.Blood uric acid can clarify a diagnosis when being more than 416 μm of ol/L as height
Uricacidemia.Superelevation protein meal is the major reason for causing purine metabolic disturbance, excessive glucocorticoid, fat, protein intake and
Heavy drinking and illness rate increase have important relationship.When serum Uric Acid Concentration is excessively high, uric acid is deposited on pass in the form of sodium salt
Section and subcutaneous tissue, lead to the generation of gout, therefore about 5%~12% can develop into gout in Patients with Hyperuricemia.Bitterly
Wind can not only invade bone and joint, but also be also easy to involve kidney and cardiovascular system.Hyperuricemia and gout are current
Seriously endanger the metabolic disease of human health.
Hyperuricemia can be caused by both sides reason：(1) uric acid generation increases：Uric acid is by endogenous and outer in human body
Property two kinds of approach in source generate, and exogenous uric acid derives from food, account for about the 20% of Uric Acid total amount；Endogenous uric acid mainly comes
Derived from nucleotide catabolism, account for about 80%；Therefore, a large amount of decomposition of high purine diet and nucleic acid in vivo can lead to blood uric acid
Raising.Wherein, xanthine oxidase is the key enzyme that uric acid generates, it, which can be catalyzed hypoxanthine and is oxidized to xanthine, reoxidizes
For uric acid.(2) underexcretion：Uric acid mainly passes through kidney excretion, kidney to the filtration for being discharged through glomerulus of uric acid,
Reabsorption is adjusted after the active secretion and secretion of reabsorption, renal tubule before secretion, wherein with renal tubule to uric acid reabsorption
Based on.Lithate is polar molecule, needs ion channel could be by renal cells film, presently found ion channel
In (lithate transport protein), anion exchanger is crucial ion channel, which can promote renal tubule to the weight of uric acid
Absorb, determine uric acid be discharged from kidney number.
Western medicine hyperuricemia is mainly in terms of following two at present：First is that the drug for inhibiting uric acid to generate, such as not fast
Purine alcohol, colchicin, non-steroid anti-inflammatory drug (NSAIDs), glucocorticoid etc.；Second is that promote the drug of uric acid excretion, such as third
Semi-annular jade pendant relaxes, sulfinpyrazone, Benzbromarone etc.；But said medicine has a different degrees of side effect, such as allergic rash, drug fever,
Upset,gastro-intestinal, leucocyte and decrease of platelet, hepatic disorder etc..
Hyperuricemia is physico-chemical examination discovery, and Chinese medicine is without corresponding disease name, but Chinese medicine is to caused by hyperuricemia
Gout is early recognized.《Synopsis Golden Chamber apoplexy joint-running》?：" pulse at CUN KOU being deep and weak, deep pulse indicating the disease affecting bone, weak i.e. main reinforcement, deep pulse indicating the kidney disease,
Weak is liver ... joint-running Huang sweating, therefore day joint-running ".From the point of view of symptom, the gout of modern medicine should belong to the bi Zheng of Chinese medicine,
The scope of " joint-running ".With regard to its etiology and pathogenesis, ancient Chinese medicine doctor discussion is a lot of, and the formation of hyperuricemia is mainly due to native endowment
Deficiency, essence in kidney are in the red, and throw off restraint thermophilic fat meat and fine grain delicious food, the with the passing of time impairment of the spleen, the dysfunction of the spleen in transport day after tomorrow, and kidney loses transpiration, whole body is caused to gasify
Mistake department, body fluid dysbolism eventually lead to interior wet growth, and damp evil disperse is formed in ying blood.Yuan Dynasty's ZHU Dan-xi exists《Further Discourses on the Properties of Things
Gout opinion》Middle theory：" that gout person, big rate is because blood is heated, own self-boiling, thereafter or relates to cold water or vertical wetland, or fan take it is cool, or
Sleeping work as wind, cold and cool to fight outside, warm blood must tremble with fear, sweat is turbid coagulate it is puckery, so having a pain.Night, then very, row was in yin for pain." it is discussed and is set to name of disease
Gout, pathogenic factor are blood-head and wind, are trembled with fear, and wetting phase is fought, and clinic is using pain as main feature.Traditional Chinese medicine treats antihyperuricemic
The research of disease is gradually taken seriously and pays close attention to, and achieves certain achievement, and curative effect has also shown many superior
Property.
