Abstract
The invention discloses a specimen preserving, fixing and accelerating agent which comprises the following components in percentage by weight: 2-20% of main additive, 0.2-5% of auxiliary additive and the balance of ethanol solution of which the concentration is 50vt%, wherein the main additive is selected from laurocapram, thiazone, menthol or isopropyl myristate; and the auxiliary additive is selected from disodium ethylene diamine tetraacetate, ethylene diamine tetraacetic acid tetrasodium salt, ethylene diamine tetraacetic acid dipotassium salt, ethylene diamine tetraacetic acid tripotassium salt, ethylene diamine tetraacetic acid calcium disodium salt or ethylene diamine tetraacetic acid zinc disodium salt. The specimen preserving, fixing and accelerating agent can effectively improve the velocity of permeability of an environment-friendly non-formalin fixing solution in human bodies, animals and plant tissues, shorten the fixing time, and improve the efficiency and the quality for manufacturing pathological sections by a pathology department.
Description
Technical field
The present invention relates to the aseptic technic field, relate in particular to a kind of specimen anti-corrosion fixation accelerator.
Background technology
Formalin (formalin, the formaldehyde dilute solution) is the most frequently used human body, animal, plant tissue specimens preservative, formaldehyde in the formalin can be combined with the amino of protein, protein generation irreversible denaturation, it is used for anticorrosion existing more than the 100 year history of human body, animal, plant tissue specimens.At hospital pathology department, Surgical Operating Room, formalin is used for the fixing of pathological tissue specimen, and to prevent tissue automatic soup-dissolving, structural deterioration, cytomorphosis, tissue specimen is fixed with fixer after exsomatizing, and makes pathological section, carries out the medical pathologies diagnosis.Medical pathology diagnosis needs high-quality pathological section, and correct sample fixedly is the first step of making high quality slices.
Formalin has high toxicity, carcinogenicity, its toxicity is 30 times of methyl alcohol, Long Term Contact formalin may cause chronic respiratory disease, Carciuogenesis, such as nasopharyngeal carcinoma, colon cancer, brain tumor, leukemia, cause memory and intelligence to descend, gastric-intestinal perforation, liver damage even stupor can occur when serious; The probability that the personnel of Long Term Contact formalin, the male sex get cancer mortality is higher 6.8 times than noncontact personnel, and the women is then high 9 times.
The non-formalin fixer of environment-friendly type of formalin has appearred substituting in recent years comprehensively, it is disclosed non-formal Malin fixer in the patent of invention of (ZL200710024048.6) such as the patent No., can be used for human body, animal, plant tissue specimens anticorrosion, fixing, product is nontoxic, avoided the occupation infringement of formalin to place staff such as sample preservation, dissection, pathological diagnosis, be subject to the attention of association area, product is used rapidly in pathology educational circles.The non-formalin fixer of environment-friendly type adopts the natural subsidence fixed mechanism, and the seepage velocity in tissue specimen is lower than formalin, causes the set time longer than formalin, and being widely used to hospital pathology department makes troubles.
Summary of the invention
The present invention is intended to overcome the deficiency that above prior art exists, a kind of specimen anti-corrosion fixation accelerator is provided, be used in conjunction with the non-formalin fixer of environment-friendly type, but the seepage velocity of the non-formalin fixer of Effective Raise environment-friendly type in human body, animal, plant tissue, shorten the set time, improve pathology department and make pathological section efficient and quality.
Specimen anti-corrosion fixation accelerator of the present invention comprises each component of following percentage by weight:
Main additive 2-20%
Auxiliary additive 0.2-5%
Surplus be concentration 50vt% (vt: concentration expressed in percentage by volume, lower with) ethanolic solution;
Main additive Main Function increases the flowability of bilayer in the bilayer of cell, lowers phase transition temperature, improves local permeability, promotes the intercellular infiltration of fixed substance; Auxiliary additive can form hydrogen bond fast in albumen after entering tissue, accelerate albuminous degeneration speed.Main additive, auxiliary additive acting in conjunction can obviously improve the seepage velocity of fixer in tissue specimen, shorten the set time.
Described main additive is selected from Laurocapram, thiophene ketone, menthol or myristic acid isopropyl ester;
Described auxiliary additive is selected from disodium ethylene diamine tetraacetate, tetrasodium salt of EDTA, EDTA Dipotassium salt, ethylenediamine tetra-acetic acid tripotassium salt, calcium disodium chelate salt or ethylenediamine tetraacetic acid disodium zinc salt salt.
Further, each component of the preferred following percentage by weight of described specimen anti-corrosion fixation accelerator:
Main additive 2-12%
Auxiliary additive 0.2-5%
Surplus is the ethanolic solution of concentration 50vt%.
Further, each component of the preferred following percentage by weight of described specimen anti-corrosion fixation accelerator:
Main additive 2-12%
Auxiliary additive 0.5-2%
Surplus is the ethanolic solution of concentration 50vt%.
Beneficial effect of the present invention is: this specimen anti-corrosion fixation accelerator has improved the non-formalin fixer of environment-friendly type effectively at the tissue sample, and the seepage velocity in zoological specimens, the plant tissue shortens the set time.Use specimen anti-corrosion fixation accelerator of the present invention, in the tissue sample is fixing, the fixed speed (seepage velocity) of the non-formalin fixer of environment-friendly type is the highest to improve 30%, has reduced the fixing used time, simultaneously SABC antigen is not produced obvious impact.
Specimen anti-corrosion fixation accelerator using method of the present invention: in the non-formalin fixer of environment-friendly type, add 5% volume specimen anti-corrosion fixation accelerator, mix, get mixed solution, this mixed solution can carry out the fixing of human body, animal, plant tissue specimens.It is 20 days that this mixed solution uses the term of validity.
