- Refers to the injection of specific immune antibodies or other cellular immune preparations to the body, so that the body immediately obtains specific immunity. It is mainly used for treatment or emergency prevention. Comparison of two artificial immune systems (see textbook P123 Table 8-2)
- 1. Antitoxin Toxoids are injected into horses several times. After the horse produces high titer antitoxins, blood is collected, the serum is separated, and purified. It is commonly used in clinical anti-toxins such as tetanus, diphtheria, gas gangrene, and botulinum. Care should be taken to prevent the occurrence of type I hypersensitivity.
- 2.Antibacterial serum is only used for the treatment of diseases caused by multi-resistant strains.
- 3. Placenta gamma globulin is generally used for prevention.
- 4. Other immune preparations currently being tested are transfer factor (TF), immune ribonucleic acid (iRNA), thymosin, interferon (IFN), interleukin-2 (IL-2), cytotoxic T cells (CTL) and LAK cells, etc.
