In terms of the drug itself, it may be slightly more effective to boost immunity with immunoglobulin than with splenic aminopeptide. Splenopeptide is a drug made from healthy bovine spleens, containing peptide amino acids and polynucleotides, which is essentially a bidirectional immunomodulator that enhances or suppresses cellular or humoral immunity, and is used in the treatment of chronic hepatitis B and allergic rhinitis. Contraindications to the drug are unclear. Note that the use of the drug is prohibited in the event of a change in its properties. The use of the drug in pregnant women, lactating women, children and the elderly is not clear. Human immunoglobulin is mainly made from the plasma of healthy people, the composition of human immunoglobulin, infusion of human immunoglobulin for patients can make patients from no immune state or low immune state to quickly reach a temporary immune protection state, generally used for the prevention of infectious hepatitis and measles, but also can be used in conjunction with antibiotics for the treatment of bacterial, viral caused by serious infections. People who are allergic to any components of human immunoglobulin are prohibited from using it. A small number of people will experience redness, swelling and painful reaction at the injection site. Note that this product should not be used if it appears cloudy or expired. After opening the bottle, it should be injected at once, and should not be used in divided doses. Therefore, in terms of the drug itself, it may be more effective to use immunoglobulin to improve immunity than splenic aminotransferrin. It is recommended that patients who need to use the above drugs should consult with the relevant departments of regular hospitals, and should not use the drugs on their own.
