Example 4
An application of ginseng stem and leaf extract oral liquid in improving livestock vaccine immunity is provided. Specifically, the oral liquid is added with water to drink for 3 days before the livestock is vaccinated, so that the immune system of the organism can be effectively activated, the organism can rapidly generate immune response after the vaccination to generate antibodies, and the antibodies have high titer, are neat and have high protection rate.
In the invention, ginseng stems and leaves are used as raw materials, the cost is low, the effective components of the ginseng stems and leaves are composed of ginsenoside Rg1 (C42H 72O 14) and Re (C48H 82O 18), and the damage loss of the effective components is small by adopting an alcohol leaching extraction method. The ginsenoside Rg1 (C42H 72O 14) and Re (C48H 82O 18) can effectively activate the immune system of organism, and has regulating effect on immune organ, immune tissue and immune cells.
Immune organs are divided into central immune organs, which consist of thymus and bone marrow, and peripheral immune organs, which consist mainly of spleen, lymph nodes, etc. By establishing a cyclophosphamide-induced mouse model with low immune function, the influence of ginseng stem and leaf saponin Rg1 (C42H 72O 14) and Re (C48H 82O 18) on thymus index and spleen index of mice is researched, and as a result, the results show that the thymus index and the spleen index of the mice with low immune function are obviously lower than those of normal mice, the thymus index and the spleen index of the mice can be obviously improved by the ginseng stem and leaf saponin Rg1 (C42H 72O 14) and Re (C48H 82O 18), and the immune defense capacity of organisms is improved by improving the thymus index and the spleen index by the ginseng stem and leaf saponin Rg1 (C42H 72O 14) and Re (C48H 82O 18).
The ginseng stem leaf saponin increases the transcription of DC secretion IL-12P40 protein and mPNA thereof by promoting the migration and development and maturation of DC precursor cells, increases the phagocytic capacity of IL-2 and phytohemagglutinin to activate macrophages, and simultaneously promotes the release of Nitric Oxide (NO), and the level of NO is also an important index of macrophage activation, so that the regulation effect of ginseng stem leaf saponin Rg1 (C42H 72O 14) and Re (C48H 82O 18) on specific immune functions and nonspecific immune functions is realized by enhancing the functions of macrophages.
T lymphocytes are important immune cells, which mediate cellular immunity primarily, and B lymphocytes mediate fluid immunity primarily. When both are stimulated by antigen, they activate, proliferate, differentiate into effector cells, which produce a range of biological effects that mediate an adaptive immune response. And the ginsenoside can obviously enhance the immunocompetence of T, B lymphocytes.
To study the effect of ginseng stem and leaf extract oral liquid on the immune effect of animals vaccinated under immunosuppression, 60 mice were randomly divided into 6 groups of 10 mice each, an immunosuppression model was established for A, B, C, D groups, and E, F groups were healthy mice. The method for establishing the immunosuppression model is to establish a mouse scalding model and inject endotoxin into the abdominal cavity of the mouse for secondary striking, so that the immune function of the mouse is reduced.
The oral liquid prepared in example 2 was fed to A, C groups with drinking water, the addition amount of the oral liquid was 0.1mL, 1 time a day for 3 consecutive days, and B, D, E, F groups were fed with no drinking water. Mice in group A, B, E were immunized with porcine circovirus type 2 (PCV 2) vaccine on day 4 of the test, C, D, F mice were immunized with foot-and-mouth disease (FMD) vaccine, blood was collected on days 0, 7, 14, 21 after immunization, and the corresponding serum IgG was detected by ELISA detection method, and the results are shown in Table 1, FIG. 1.
Table 1: indirect ELISA assay results
As can be seen from Table 1, the increase in the A, C group antibody was significantly increased for the different vaccines, and A, C group serum D was used for immunization against 14D and 21D 450nm Significantly higher than the B, D group and also higher than the E, F group in which healthy mice are located. It can be seen that the product of the invention has a positive effect on enhancing the immune effect of animals after vaccination under immunosuppression.
The foregoing is a description of one or more embodiments of the invention, which are specific and detailed, but are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
