Summary of the invention
The object of the present invention is to provide a kind of compound recipe protease medicine for the treatment of hyperplasia of prostate.This prescription rationally, and is easy to use, safe and effective, with low cost.Through zoopery and clinical observation: this medicine can make the rapid deactivation of organizing of injection zone, protein coagulation, degeneration, sealing regional flow, the side effect of having avoided whole body to absorb.Under the combined effect of functional enzyme, the gland tissue of degeneration is dissolved, variation such as Proteolytic enzyme, tissue liquefaction.It can not only make the change on the gland tissue genetic morphology of injection zone, and atrophy finally appears in body of gland, and volume-diminished is so can effectively remove the symptom of urinating and blocking.
Another object of the present invention has been to provide a kind of method for preparing compound recipe protease medicine, and technology is simple, stable performance, and it is convenient to store, and is suitable for mass production.
For many years, owing to be subjected to the inspiration of tissue culture and cell culture, begun the experimental exploring of enzyme process dissolving prostata tissue.Prostata tissue is rich in collagen and proteoglycan.Form multiple spherical shape tuberosity during prostatic hyperplasia in the body of gland, contain a large amount of collagen fiber in the tuberosity.Hydroxyproline content increases in the body of gland, makes fibrous tissue stiff, tetanic, collagen forfeiture elasticity, and then cause that mechanical urinating be obstructed.Contain a large amount of α receptors in prostata tissue and the neck of bladder sphincter, it is controlling the contraction of smooth muscle, and influence is urinated.Prostatic hyperplasia mainly is based on interstitial proliferation.Between can rise to hypertrophy by just often 2: 1 time 5: 1 of the ratio of matter and epithelium.According to these characteristics of prostatic hyperplasia, it makes (consumption is a weight portion) by following raw materials according compound recipe protease medicine:
Hyaluronidase 0.3-1.5 bromelain 0.2-1.0 trypsin 0.2-2.5
Bacillus polymyxa Neutral proteinase 0.1-0.8 collagenase 0.2-1.5 gentamycin 0.02-0.1
Dexamethasone 0.02-0.1 deoxyribonuclease 0.1-0.5 chitosan 0.00-0.1
Terazosin 0.0-1.5 mannitol 0.0-2.0 agarose 0.2-1.2
TritonX 0.2-1.5
A kind of preparation process of compound recipe protease medicine for the treatment of hyperplasia of prostate is as follows:
1. take by weighing above-mentioned each raw material in proportion.
2. mannitol (only using agarose among the embodiment 3) and agarose are dissolved in respectively in the solvent, it is standby to sterilize.
3. prepare chitosan gel rubber slow releasing agent (embodiment 3 and 6 can save this step).
● the spirit of vinegar of preparation 0.1mol/L.
● add 2% chitosan, stirring is dissolved it fully.
● regulate between the pH to 5.5-6.0 with the 1mol/L sodium hydroxide, be the spirit of vinegar chitosan solution.
● the spirit of vinegar chitosan solution is added in the terazosin, fully stirring and dissolving.
4. in the buffer that contains calcium, zinc ion, add chitosan gel rubber slow releasing agent and hyaluronidase, bromelain, trypsin, Bacillus polymyxa Neutral proteinase, collagenase, gentamycin, dexamethasone, deoxyribonuclease, TritonX, dissolving and mixing respectively.If preparation is improper, can cause the solution muddiness.
5. after degerming, detect the endotoxin content of preparation.Freeze dried powder is made in qualified back under aseptic condition, packing is stand-by.
The present invention has finished experiment in vitro and the human clinical observes.When testing with the prostata tissue that exsomatizes, this medicine is lytic gland soma rapidly; A certain amount of enzymatic solution of injection in the prostate body of gland that exsomatizes, injection zone caves in, is cellular change in 24 hours, and peripheral body of gland subsides, tissue liquefaction as gelatin; And the body of gland of injection solution no change still not.After having injected this preparation in the prostate body of gland of 12 old dogs, the observation that lasts 4 months, animal all survives.Prostate size before and after the medicine injection is seen Fig. 1, Fig. 2.B ultrasonic and measured result show: the prostate body of gland has dwindled 42-70% before the injection, sees Table 2; Tangible cavity be can see in the body of gland, Fig. 3, Fig. 4, Fig. 5 seen.Inject and be also shown in liquefaction tissue residual in the cavity after 4 months in the body of gland.Confirm after deliberation: along with the prolongation of time, the body of gland internal cavity is with closure, and the body of gland volume also can further dwindle, and sees Fig. 6.Simultaneously, whole body of gland is the change of sponge sample, body of gland capsuleization.Histological observation is found: the glandular tube chamber dwindles obviously, karyopyknosis, smooth muscle fiber fracture.All sign explanations: the gland tissue of medicine injection is inactivation, tissue liquefaction.Research worker has also been observed the toxicity of said preparation.Carried out the serum enzyme labeled compound assay before injecting the back the 2nd day, 30 days and putting to death, the result is relatively preceding with injection, difference that there are no significant.After showing the interior injection of this preparation body of gland, no whole body absorbs, and can not bring liver injury.Over one year, under numerous volunteers' an urgent demand,, select advanced age or patient that can not tolerate surgery to carry out clinical experiment through strict organization procedure.Before the applying date, 22 routine patients have been treated.By follow-up observation more than a year, behind the patient infusion in January symptom just have clear improvement, the night urination number of times reduces (patient by being reduced to 0-2 time/night at original 6-10 time/night), the urine flow rate is multiplied, and urinates line and increases slightly, urinates effectively.B ultrasonic is measured prostate volume and is dwindled about 50%, sees Table 1.Last observation more than a year, the patient feels quite pleased therapeutic effect, inject said preparation certainly after, took the medicine of any treatment prostatic hyperplasia never again.Because in vivo test is to carry out, marked difference is arranged when its situation and stripped (under tissue devitalization's condition) in the organism of living.Vasoganglion is very abundant in the prostate body of gland, and as blocking blood flow not, the enzymatic solution of injection can reduce the drug level of local organization rapidly to the whole body diffusion; The mortifier that also has plurality of enzymes in addition in the body.As not eliminating these influence factors, the effect of enzyme will be had a greatly reduced quality; As absorb excessively, and also can increase the burden of liver, cause that liver function one crosses sexual abnormality.Confirm through zoopery and clinical practice: this formula combination can be brought into play the synergism of various compositions better.The activity of demolition purpose tissue and original structure targetedly under the combined effect of plurality of enzymes.Treated agarose can effectively destroy the intravital mortifier of gland, make the injection zone tissue that albuminous degeneration take place, solidify, cause tissue devitalization's (similar isolated condition), thereafter the compound recipe enzymatic solution that reinjects just can reach and dissolve body of gland, liquefaction, softening tissue, dwindles the effect of body of gland volume.The compound recipe protease preparation possesses following several effect at least.
1. make injection zone tissue devitalization, albuminous degeneration, coagulation necrosis, minimizing and occluding vascular, blocking blood flow.
2. by the Digestion of enzyme, tissue is dissociated into cell mass or individual cells.Under the effect of functional enzyme, make exfoliative cyte further lose adhesive ability and multiplication capacity again.In other words, through after a series of variations, local organization has lost regenerated primary condition.So think: the effectiveness of this technology is trustworthy.
3. the gland tissue of degeneration dissolves, liquefies, and scope progressively spreads to periphery.Injection zone visible " opaque dark area of fluid " under the B ultrasonic.
4. liquefaction is organized in the unified regulation and control of body down, and a part is handled by the intravital macrophage phagocytic of gland, and another part flows into urethra through glandular tube, excretes.Body of gland is softening, volume-diminished.
5. histological examination is shown: the atrophy of injection zone glandular tube, and the glandular epithelium karyopycnosis, the muscle fiber fracture, it is loose netted that a matter is.Above-mentioned variation prompting: the tissue after the enzyme dissolving gangrenosum acne occurs and changes, and the character of its variation should be irreversible.Inference thus: the effect of this treatment should be secular.
6. after the clinical practice, patient's non-evident effect.Do not see heating, allergy, liver, renal function injury show after enzymatic solution is injected only to be defined in around the injection zone that to the organ beyond the body of gland and harmless, no whole body absorbs.
7. agarose has dual function.Solidified structure, sealing blood vessels destroys the α receptor; Under the bio-electric field effect, help the diffusion of enzyme, enlarge the scope of dissolving tissue and strengthen liquefaction.
The present invention compared with prior art has the following advantages and characteristics.
One. determined curative effect.Effective percentage reaches (the experiment initial stage is because of lacking experience, so influenced therapeutic effect) more than 90%, along with empirical accumulation, believes that curative effect also can improve, and this result is higher than present medication effect far away.
Two. indication is wide, and is safe.Various high risk patients, the equal injectable of patient that the heart, brain, pulmonary function difference can not tolerate surgery.
Three. method is easy.General patient only need inject once and can take effect, and after this withdraws the medicine of all treatment prostatic hyperplasia.
Four. this law is delivered to medicine in the prostate by injecting pathway.Dwindling prostate volume is liquefied by body of gland and realizes.Its maximum characteristics are that wound is little, have kept the integrity of prostatic urethra, do not damage urethra; And existing " electrotomy " the excision prostata tissue of performing a surgical operation in the urethra, so be conspicuous to the damage of urethra.Patient's post-operative recovery is slow.
Five. medical expense is low, reduces more than 60% than expenses of surgical treatment.
Six. the no whole body of injection absorbs in the body of gland, can not cause harmful effect to the patient.The present invention is applicable to hyperplasia of prostate, chronic prostatitis (married, do not educate person).The inventive method safety, no pain, good effect, expense are few in a word, and rehabilitation is fast.For inoperable patient, provide a kind of ideal method undoubtedly.The said preparation raw material sources are wide, and properties of product are stable, are suitable for large-scale production, the market prospect optimism, and social benefit and economic benefit are huge.
