Abstract

The invention provides a long-term-preserved immune cell gel preparation and a preparation method thereof. The gel preparation contains immune cells and a gel matrix, wherein the gel matrix mainly contains the following components: deionized water, dextran, a mistletoe leaf extract, propylene glycol alginate, oleyl alcohol and guaiacum. The method comprises the following steps: preparing the mistletoe leaf extract; and dissolving the mistletoe leaf extract into deionized water, standing for one night, adding propylene glycol alginate, oleyl alcohol and guaiacum, stirring, adding dextran, stirring, preparing the gel matrix, adding the immune cells into the gel matrix, and uniformly stirring. According to the preparation method, the cell activity of the immune cells in a long-term preservation process can be guaranteed, meanwhile, the stability of the immune cell gel preparation can be improved, the pesticide effect of the long-term-preserved immune cell gel preparation can be guaranteed, the drug release efficiency can be improved, and the mildewing can be prevented; and the immune cell gel preparation is strong in practicability.

Description

technical field [0001] The invention belongs to the technical field of gel preparations, in particular to a long-term preservation immune cell gel preparation and a preparation method. Background technique [0002] At present, the diagnosis and treatment of diseases has entered the era of molecules and cells. Stem cells and immune cells have great therapeutic potential. Immune cells refer to cells that participate in or are related to immune responses. Immune cells generally include lymphocytes, dendritic cells, monocytes / macrophages, granulocytes, mast cells, etc. Immune cells can be divided into many types, and various immune cells play important roles in the human body. At this stage, the application of immune cells is relatively limited, and no immune cell preparations have been seen at home and abroad. [0003] Gel preparation is a new drug dosage form that has emerged in China in recent years. Gel preparation refers to a thick liquid or semi-solid preparation in the ...
