Description

The purposes of Chinese milkvetch seed extractive and preparation method
Technical field
The present invention relates to the natural drug technology, particularly relate to a kind of purposes and preparation method of Chinese milkvetch seed extractive.
Background technology
Kidney is the device of wanting of the five internal organs, the congenital foundation, its effect is to discharge the intravital metabolite of people, the useful component in the metabolite is reuptaked in the ex vivo, again produce refuse---urine is responsible for discharge by ureter, bladder.Simultaneously, kidney still is very important endocrine organ in the body, is responsible for making the erythropoietin that promotes hemopoietic, and activity of vitamin d3 also is responsible for the decomposition of insulin in the body.In case renal function suffers damage, refuse is accumulated in vivo, then can produce very big harm to health.
At present China kidney patient has reached 9,000 ten thousand people, and wherein, uremic patient every year is just with the speed increment of 5%-10%.According to data, since 2006, chronic nephropathy has become the fourth-largest disease killer after cardiovascular and cerebrovascular disease, tumor, diabetes, and from global general status, the control of chronic kidney disease is faced with stern challenge.And in chronic renal disease, nephrotic syndrome has accounted for very big proportion [1]
(nephrotic syndrome NS) is the common disease of Urology Department, multiple disease to nephrotic syndrome! A lot of kidney diseases all show as nephrotic syndrome clinically [2], it is not an independence disease, but by multiple reason, comprises one group of clinical syndrome in the renal glomerular disease that chronic nephritis causes.The typical case shows as a large amount of albuminuria, hypoalbuminemia, edema, hyperlipemia.Because hypoproteinemia, hyperlipemia and edema all are a large amount of albuminuretic consequences, therefore, the standard of diagnosis should be based on a large amount of albuminuria [3]And a large amount of albuminuria are the important independently risk factors that cause renal function to worsen, no matter be constitutional or Secondary cases nephrotic syndrome, if a large amount of albuminuria can not get controlling timely and effectively, to cause nephridial tissue, particularly between kidney matter carry out fibrosis, carrying out property of renal function goes down, and develops into renal failure in latter stage at end gradually [1]Therefore, its treatment key is to reduce or eliminate albuminuria [2]
Aspect its treatment measure, adrenocortical hormone is the choice drug of treatment nephrotic syndrome, and as prednisone, prednisolone, dexamethasone etc., but it is a lot of to take such drug side effect for a long time, quite serious sometimes [3]Simultaneously, the part patient exists hormone dependence, hormonal resistance, hormone not to tolerate and phenomenon such as outbreak repeatedly [1]This a part of patient can try out cytotoxic drug, be situated between as cyclophosphamide and benzenebutanoic acid nitrogen, but the same toxic and side effects of this type of medicine is very big and how the recidivist does not advocate to carry out the medication second time to alleviating again after the medication, in order to avoid poison [3]In addition, also can select cellular immunization inhibitor---Ciclosporin A for use, but this medicine also there is serious toxic and side effects, the most serious is liver, nephrotoxicity, its nephrotoxicity incidence rate is at 20%-40%, thus should not be for a long time with this medicine treatment nephrotic syndrome, more should not be easily with this medicine as choice drug [3]Because of the limitation of above-mentioned various kinds of drug existence and serious toxic and side effects, used by people gradually in conjunction with the traditional Chinese medical herbal treatment nephrotic syndrome, but up till now, still there is not a species specific efficient medicine of low toxicity that is widely used in nephrotic syndrome and reduces urine protein.
Herba Astragali Melilotoidis (Herba Astragali Sinici) (Astragalus sinicus Linn.) is a pulse family Radix Astragali platymiscium, is distributed in each provinces and regions, the Yangtze river basin, is longer than the hillside sylvan life, limes marginis and meadow.Medicinal part is herb and seed, the function that has heat-clearing and toxic substances removing, makes eye bright and invigorate blood circulation [4]Semen astragali sinici kidney shape or rhombus contain the flavone and the glycoside material thereof of Wheat Protein according to the literature [5], triterpene glycoside material [6], materials such as aspartic acid and polysaccharide.But up to now, do not see its modern pharmacological research report.
Above-mentioned unfavorable present situation in view of present nephrotic syndrome clinical application, the present invention utilizes the mRNA IN ADRIAMYCIN NEPHROPATHY rat model that multiple natural plant extracts has been carried out pharmacological experiment study, observe of the influence of these extracts to urine protein content, it is unexpected that the discovery Chinese milkvetch seed extractive have remarkable reduction urine protein, improve the pharmacological action of the nephrotic syndrome, effect and prednisone are suitable, and have no side effect.Content of the present invention is not seen relevant report both at home and abroad.
