The invention relates to an oral spray for inflammatory diseases of the oral cavity and a preparation method thereof. The oral spray comprises the following components: 0.1-5% of water-soluble chitosan, 0.5-5% of propolis extract, 0.1-1% of lactoferrin, 0.01-0.5% of lactoperoxidase, 0.1-0.5% of lysozyme, 0.01-0.1% of immunoglobulin, 1-10% of bovine colostrum extract, 1-10% of anti-caries sweetener, 0.8-1.2% of cold aromatic, 0.1-1% of preservative and the balance of water for injections. The preparation method is characterized by mixing the components, stirring uniformly, filling into an oralsprayer, and sterilizing at 85 DEG C for 15 minutes to obtain the finished product. The oral spray has the effect of immediately and rapidly treating inflammatory diseases of the oral cavity and the functions of resisting bacteria and viruses, relieving pains, reducing gum inflammation and blooding, promoting the healing of oral ulcer wounds, treating acute and chronic pharyngitis, moistening andfreshening the oral cavity and removing halitosis. The oral spray has the advantages of simple and convenient large-scale production process and no environmental pollution in the production process.

The invention relates to separation, authentication and application of a bursa fabricius heptapeptide for promoting vaccine immunoreaction. The immunoactive peptide is a small-molecular polypeptide from bursa fabricius, has the amino acid compoiiton of Gly Gly Cys Asp Gly Ala Ala and is simple in structure and extremeley weak in immunogenicity. The active peptide has a function of promoting the vaccine immunoreaction and has effect of simulating antibody generation and cell immunoreaction, enhancing lymphocyte activity and improving vaccine immunity on mice and chickens. The heptapeptide can be applied to the animal vaccine application research as a vaccine adjuvant or immunopotentiator so as to improve the immune response ability of animal bodies for specific antigens and improve the vaccine immunity, thereby improving the disease infection resistant ability of the animal bodies, and can be applied to the fields of basic immune research, clinical application research and the like.

The invention discloses a hybrid liriodendron somatic embryogenesis synchronization control method. In the method, 2,4-D concentration is reduced gradually by utilizing a growth hormone regulating mechanism; kinetin (KT) with the dose of 0.5 mg.L<-1> is added to induce uniform embryonic cell masses; the embryonic cell masses are subjected to fractional culture by a mechanically sieving method; and different subsequent synchronization control methods are adopted according to different cell mass sizes and somatic embryogenesis modes. After the synchronization control, the somatic growth synchronization ratio of hybrid liriodendron subjected to classified screening at the stage of globular embryo reaches about 90 percent; the synchronization ratio of fractional treatment at the stages of heart-shaped embryo and torpedo-shaped embryo is about 40 percent; after a proper period of refrigeration, the synchronization ratio is increased to some extent; and the conversion rate of a mature embryo, which develops from a material at the stage of globular embryo, to a regeneration plant can reach 70 to 80 percent.

The invention discloses polysaccharide cellulose medical gum with high mechanical strength and capability of promoting wound healing. The polysaccharide cellulose medical gum with high mechanical strength and capability of promoting wound healing is prepared from the following raw materials: sodium carboxymethyl cellulose, astragalus polysaccharides, polyurethane modified starch adhesive, sodium alginate, water for injection and the like. The invention further discloses a preparation method of the polysaccharide cellulose medical gum with high mechanical strength and capability of promoting wound healing. The polysaccharide cellulose medical gum with high mechanical strength and capability of promoting wound healing has good physical adhesion property, is antibacterial, has effect of promoting wound healing, and has excellent biological compatibility; and the polysaccharide cellulose medical gum with high mechanical strength and capability of promoting wound healing, which is formed by optimizing a formula, is moderate in viscosity and easy to wash, a reliable, uniform and soft protecting film can be formed on a wound surface, a wet environment of the wound surface is formed, the medical gum is used for repairing cells and can inhibit scar formation, by addition of astragalus polysaccharides with high mechanical strength and capability of promoting wound healing, cell repair can be promoted, and therefore, the polysaccharide cellulose medical gum with high mechanical strength and capability of promoting wound healing has high clinical application value.
