Description
The present invention relates to a kind of medicinal preparation that contains peptide class material and preparation method thereof, particularly a kind of small molecule glycoprotein biological agent and preparation method thereof.
In the prior art to the medicine of treatment rheumatoid arthrosis class toxic side effect all, Radix Tripterygii Wilfordii etc. for example, the patient can not adhere to life-time service, the patient who has even be forced to therapy discontinued.
Small molecule glycoprotein biological agent of the prior art is that to adopt blood of human body be raw material, for example Chang Yong transfer factor [N-TF], and it isolates leukocyte exactly from blood of human body, behind 4～5 freezing-thawing and crackings, give small-molecular peptides.This prior art has following several weak point: biological activity is not high; It is not obvious that antagonist forms the cell facilitation; Therapeutic domain is narrow, and is not good to some immune diseases and anaphylaxis eqpidemic disease therapeutic effect, for example, and rheumatoid arthrosis class, bronchial asthma etc.; The cost of material height, so the preparation cost is more expensive, the scale that has restricted preparation from economic angle is used.
The objective of the invention is to overcome weak point of the prior art, and a kind of biological activity height is provided, it is obvious that antagonist forms the cell facilitation, therapeutic domain is wide, have no side effect, raw material sources are extensive, small molecule glycoprotein biological agent that cost of manufacture is low and preparation method thereof.
The objective of the invention is to realize by following approach.
Small molecule glycoprotein biological agent, is made after freezing-thawing and cracking and the dialysis through separating by biological tissue of human body, and said biological tissue of human body is a kind of healthy human body body early embryo tissue of obtaining after artificial abortion.

Experiment showed, in the biological preparation molecular weight at the part ubiquity below 12000 to antibacterial, the immunity of virus; Molecular weight has nonspecific immunological enhancement and immune induction effect less than 3500 part.
Said biological preparation is every milliliter of nitrogen content 10 ± 1mg preferably.
The small molecule glycoprotein biological agent preparation method, getting biological tissue of human body is raw material, dialyses behind freezing-thawing and cracking again, said raw material is the healthy human body body early embryo tissue of obtaining artificial post-abortion, its preparation process is as follows, removes impurity, smashs to pieces and makes tissue homogenate, said embryonal tissue is put into tissue mashing machine, smash rotating speed to pieces to low 8000 rev/mins, smash number of times to pieces at least 8 times, smash 50 seconds～100 seconds time at every turn to pieces, freeze thawing at least 3 times was dialysed 36～48 hours.
Smash rotating speed to pieces and be preferably 12000 rev/mins, smash number of times to pieces and be preferably 12 times, the time of smashing to pieces is preferably 60 seconds at every turn.
Said freeze thawing, cryogenic temperature are preferably-15 ℃, and melt temperature is preferably 37 ℃, and number of freezing and thawing is preferably 5 times.
In sum, the present invention has following advantage compared to existing technology: contain 18 seed amino acids, wherein cystine is up to 2.96mg/100ml, and modern medicine shows that cystine has very strong capability of resistance to radiation; Be rich in the trace element that the multiple human body utmost point needs, wherein ferrum Fe, copper Cu, manganese Mn are respectively 0.14 mcg/ml, 0.018 mcg/ml, 0.02 mcg/ml, and ferrum can promote the human body hemoposieis; The biological activity height, it is obvious that antagonist forms the cell facilitation.Following table is represented the present invention and transfer factor [N-TF], and the micromolecule thymic factor relatively uses, the antibody forming cell's parameter that is manifested, and reagent dosage all by the amount conversion course of treatment, calculate by 10 times of amounts that the mice consumption is behaved,

| Transfer factor | 6 | 58385±15028 |
| The micromolecule thymic factor | 6 | 51783±7786 |
Therapeutic domain is wide, and clinical trial shows that the present invention is to treatment bronchial asthma, and rheumatoid arthrosis class, skin allergic disease etc. have significant curative effect, total effective rate to reach more than 90%; Have no side effect, appearance colorless of the present invention is transparent, and the apyrogeneity reaction does not have irritated reaction; Raw material sources are extensive, and are the embryonal tissues that makes full use of after the artificial abortion dilatation and curettage, cost of material need not take place, and because processing technology is simple, utilize hospital's test chamber existing equipment to prepare, and so the product cost is low, are convenient to popularization.
Below we carry out more detailed description by embodiment to the present invention.
