The method of obtaining immunostimulant
(57) Abstract:The method is designed to obtain immunostimulant as a food additive. The method consists in the following. Isolated bone marrow cells from the bone marrow of small cattle, washed and incubated them in oncotic solution with a concentration of 0.85 - 0.90%, and then centrifuged supernatant. The method allows to extend the resource base, to accelerate and reduce the cost of obtaining immunostimulant as a food additive. table 1. The invention relates to the field of food industry, in particular to methods for food additives.A method of obtaining extracts for medical purposes, having an immunostimulating action, from raw materials of animal origin by isolating bone marrow, heat free from pyrogens water and keeping at 80oC for 5 min, centrifuge and use the supernatant for subsequent ultrafiltration, electrodialysis (see and.with. N 1442064, MKI A 61 K 37/24, 1988, BI N 44).However, the known method is difficult to implement and economically unfeasible to obtain immunostimulant in the form of nutritional supplements.Enableuser by separating the cells from the bone marrow of animals, followed by incubation in growth medium, the preconcentration and elution supernatant (see and. C. N 1005790, MKI A 61 K 39/00, 1983, BI N 11).However, the known method is time-consuming, because it requires strict sterile conditions, expensive due to the use of nutrient medium 199, which includes the following components (g/l):NaCl-8, KCl-0.4, MgCl26H2O-0.1, MgSO47H2O-0.1, Na2HPO47H2O-0.06, KH2PO47H2O-0.06, CaCl2-0.14, NaHCO3-0.6, fanart-0.02, glucose-0.6, the application of which does not allow to use it for food purposes. The method involves the use of only ordinary bones of pigs.Thus, the problem to be solved in the present invention, is to obtain immunostimulant in the form of dietary supplements. The technical result obtained by carrying out the method is a simplification of the process and the expansion of raw materials.To achieve provided by the invention of the technical result in the production method of immunostimulant by separating the bone marrow cells of animals, followed by incubation in growth medium, centrifugation supernatant, according to the invention, the cells isolated from the bone marrow of small horn the entrances take in a given concentration.As a result of experiments, the authors showed the possibility of using oncotic solution with a concentration of 0.85 - 0.90% as a nutrient medium for the cells in the bone marrow of animals. The authors found that you can use not only the bone marrow cells of the pigs and small ruminants. The cell concentration was chosen so as to obtain the maximum yield of biologically active components and to maintain cell viability.Analysis of patent and scientific literature showed that of the prior art, the authors have not identified technical solutions, including a collection of characteristics that are similar or equivalent to the claimed.This allows to make a conclusion on the conformity of the proposal with the criteria of "novelty" and "inventive step".The proposed method for immunostimulant is as follows.When the butchering of carcasses at the slaughterhouse retrieved ribs of animals, it can be ribs pigs or small cattle. Washed cells from the rib bones produce syringe with oncotic solution with a concentration of 0.85 - 0.90%. Oncotic solution is a natural environment for Iznik selection, and incubation, without compromising the integrity of the cell. Then produce three times washing of the cells with the same solution: a suspension of cells centrifuged, the supernatant fluid is drained off, and the residue diluted oncotic solution. In the last set concentration by counting cells per 1 ml oncotic solution in the chamber Goryaeva. In order to achieve a given concentration of cells after counting the produce or concentration, or dilution of the suspension of cells oncotic solution. What is the cell concentration in the inventive method of obtaining immunostimulant the authors do not specify, since it is the "know-how" in the present invention. And the authors do not wish this moment was uncovered. At this concentration, the cells are placed in culture bottles of 100 - 150 ml of sediment in the bottle, the volume of one litre. Incubation is carried out at a temperature of 37oC for 14 to 18 hours after incubation, a suspension of cells centrifuged, the supernatant determine the amount of protein by the method of Lowry, and then either used in the experiment, or stored at a temperature of -12oC.Evaluation of immunological activity derived immunostimulant conducted in vi is private run.Example 1. When the butchering of carcasses at the slaughterhouse remove ribs pigs. Cells wash away from the rib bones of pigs by fioratura, washed and incubated in the specified concentration for 16 hours at a temperature of 37oC in the culture vials of 100 - 150 ml of suspension in a vial, the volume of which 1 liter of the Supernatant liquid is separated from the cells by centrifugation at 2000 minutes the supernatant determine the amount of protein by Lowry. The content of 2 mg/mlEvaluation of immunological activity performed in the system in vivo for the local introduction of faction mice at 4 days secondary immune response to sheep erythrocytes in a dose of 100 µg contained in 0.1 ml of fidirectory, pad hindquarters. In the other group, which served as a control, enter fisierului. The next day in these mice, remove the popliteal lymph nodes and define them in the number of antibody productive cells, comparing their number in the experiment and the control.The coefficient of stimulation of antibody productions To determine in both models calculated by the ratio of the number of the KLA in the experience to the corresponding number of the KLA in control.Example 2. When the butchering of carcasses at the slaughterhouse remove ribs small ncentratio for 16 hours at a temperature of 37oC in the culture vials of 100 - 150 ml of suspension in a vial, the volume of which 1 liter of the Supernatant liquid is separated from the cells by centrifugation at 2000 minutes the supernatant determine the amount of protein by Lowry. The content of 2.1 mg/ml together with the selection of cells with medium 199, washing and incubation are in the same environment. Conditions for obtaining analogous to example 1. The protein content of 2.5 mg/mlEvaluation of immunological activity performed in the system in vivo for the local introduction of faction mice at 4 days secondary immune response to sheep erythrocytes. In the case of obtaining compositions with medium 199 in the group served as control, injected with medium 199.The coefficient of stimulation of antibody productions To determine in both models is calculated as the ratio of the number of KLA in the experience to the corresponding number of the KLA in control.Example 3. When the butchering of carcasses at the slaughterhouse remove ribs pigs. Cells wash away from the rib bones of pigs by fioratura, washed and incubated in the specified concentration for 16 hours at a temperature of 37oC in the culture bottles. The supernatant liquid is separated from the cells by centrifugation at 2000 minutes the supernatant operadelaware to use products, subjected to heat treatment, and to maintain its biological activity, the supernatant is heated at 100oC for 10 minutesEvaluation of the immunological activity of the composition subjected to heating, is carried out in the system in vivo is similar to the first two examples. The coefficient of stimulation of antibody productions To determine in both models calculated by the ratio of the number of the KLA in the experience to the corresponding number of the KLA in control.Example 4. When the butchering of carcasses at the slaughterhouse remove ribs small cattle. Cell wash, washed and incubated with medium 199. Incubation at a given concentration carried out for 16 h at a temperature of 37oC in the culture bottles. The supernatant liquid is separated from the cells by centrifugation at 2000 minutes the supernatant determine the amount of protein by Lowry. The content of 2.8 mg/mlWhen choosing the ways of preserving food compositions considered cooling at 0 to 4oC, freezing at -18oC and storage at -12oC for 1 month. Cooling was not effective due to rapid contamination, and the fraction subjected to freezing and storage at Racchi mice at 4 days secondary immune response to sheep erythrocytes.The technical nature of the claimed invention was compared with the prototype (see and.with. N 1005790, class A 61 K 39/00, 1983, BI N 11).The coefficient of stimulation of antibody productions To determine in both models calculated by the ratio of the number of the KLA in the experience to the corresponding number of the KLA in control.Data examples are given in the table.Thus, the proposed method allows to obtain bone marrow cells not only from the bones of pigs, but the bones of small cattle, which can significantly extend the raw materials for the production of dietary supplements. Immune obtained by this method, retains its biological properties both at high and at low temperatures. Compared with the known method of producing stimulator antitelomerase the proposed method for obtaining reduced by 2 to 4 h; simplified due to the refusal of the gel filtration, lyophilization; replacement of the nutrient medium 199 oncotic solution significantly reduces the cost of the method, the composition obtained in this way can be stored at low temperatures.The immunostimulant in the form of dietary supplements will allow you to get the products for spamai pesticides and food additives are well known formulation of meat products with the introduction of the proposed immunostimulant. The method of obtaining immunostimulant by separating the cells from the bone marrow of animals, followed by incubation in growth medium, centrifugation of the supernatant liquid, characterized in that the cells isolated from the bone marrow of small cattle, as well as the nutrient medium used oncotic solution with a concentration of 0.85-0.90%, and the cells take in a given concentration.
