Veal-blood protein-removed extract infusion and its preparation process

Abstract

The invention is calf dehemoglobinize extract transfusion and its manufacturing method. The amino acid and small peptide in the extract of the calf dehemoglobinize can be polymerized into high molecular peptide and large molecular weight peptide, thus the medicine has antigenicity and reduces the biology activity of the medicine, and causes the increase of clinic hypersusceptibility. The ingredients of the calf dehemoglobinize are: the calf dehemoglobinize extract and osmotic pressure regulator, the calf dehemoglobinize extract is extracted from the calf blood or blood serum, the extract solid contains nitrogen and amino acid, its weight shares are: amino acid is 20.0-30.0, the nitrogen 12.5-18.75, the osmotic pressure regulator 50-100, pH value is 5.5-8.0, the product is a little yellow or yellow transparent liquid. The product can be applied to cure cerebral ischemia, cerebral dementia, brain trauma and incompetence of brain fucntiosn, and so on, they are all brain cell metabolism handicap diseases; it also can be applied to cure the twig artery, vein circulation obstruction, and artery angiopathy.

Description

Technical field: [0001] The invention relates to a deproteinized calf blood extract transfusion and a preparation process thereof. Background technique: [0002] The calf blood deproteinized extract solution is mainly composed of amino acids, small peptides and other nitrogen-containing compounds. Amino acids and small peptides can be polymerized with each other in a natural state to form large molecular weight peptides, and peptides can be polymerized into high molecular weight peptides. Precipitation in the form of polymers or existing in the solution in the form of high-molecular peptides makes the drug produce antigenicity and reduces the biological activity of the drug. This is the main reason for the increase in clinical allergic reactions caused by the deproteinized calf blood extract solution. With the prolongation of time, the incidence of adverse reactions also increases immediately, and in clinical medication, calf blood deproteinized extract solution is dissolved...

Problems solved by technology

[0002] Calf blood deproteinized extract solution is mainly composed of amino acids, small peptides and other nitrogen-containing compounds. Amino acids and small peptides can be polymerized with each other to form large molecular weight peptides in a natural state, and peptides can be polymerized into high molecular weight peptides. Precipitation in the form of polymers or existing in the solution in the form of high-molecular peptides makes the drug produce antigenicity and reduces the biological activity of the drug. This is the main reason for the increase in clinical allergic reactions caused by the deproteinized calf blood extract solution. With the prolongation of time, the incidence of adverse reactions also increases immediately, and in clinical medication, calf blood deproteinized extract solution is dissolved in sugar and saline for use, which not only increases the probability of drug contamination, but also affects the safety of drug use sex, but also increases the workload of medical staff
