It has the biological activity of human natural IL-2, including increasing lymphocyte mitosis, proliferating cytotoxic T cells, natural killer cells and lymphokine-activated killer cells (LAK), and enhancing their killing activity. It can induce the production of some cytokines such as tumor necrosis factor, IL-1 and gamma interferon. It has antiviral, anti-tumor and immune enhancement effects.

Immunoglobulin injection is a passive immunotherapy that transfers a large amount of antibodies to the recipient, allowing the recipient to quickly reach a temporary immune protection state from a low or no immune state. The interaction between antibodies and antigens directly neutralizes toxins and kills bacteria and viruses, and has a certain effect on preventing bacterial and viral infections.

This product contains high titer rabies antibodies, which can specifically neutralize rabies virus and play a passive immunization role.

1. Increase blood volume and maintain plasma colloidal osmotic pressure: Albumin accounts for 80% of plasma colloidal osmotic pressure and mainly regulates the dynamic balance of water between tissues and blood vessels; 2. Transport and detoxification: Albumin can bind to both anions and cations, can transport different substances, and can also transport toxic substances to detoxification organs; 3. Nutritional supply: Tissue protein and plasma protein can be converted into each other. When nitrogen metabolism is impaired, albumin can serve as a nitrogen source to provide nutrition for tissues.

Albumin accounts for 52%-56% of the total plasma protein in healthy people. Its main function is to maintain normal colloidal osmotic pressure of plasma (accounting for 70%-80% of the total colloidal osmotic pressure of plasma). Intravenous infusion of this product can promote the entry of interstitial fluid into blood vessels. Plasma albumin has a high affinity for certain ions and compounds, and can reversibly bind to these substances to play a transport function. Albumin also provides the body with a large amount of amino acid reserves. This function of 50ml 20% human albumin is equivalent to 400ml whole blood.
