System.
Background technique
Blood product includes that menses propagate pathogen (virus, bacterium, protozoon, conveyor screw etc.) infection, blood cell safely
Transfusion-related graft-versus-host disease caused by (such as lymphocyte) etc..The common method of Viral inactivation techniques includes bar in blood plasma
This moral sterilization, S/D method, membrane filter method, methylene blue method and riboflavin photochemical method etc., wherein methylene blue method is applied at home
Relatively wide, but some are insufficient for this method, the loss of plasma protein is larger after residual toxicity, processing including serge blue, operation is numerous
It is trivial etc.;The method for preventing transfusion-related graft-versus-host disease is that (inactivation lymphocyte) is irradiated to blood.
The method that riboflavin photochemical method inactivation of viruses is considered to have development prospect, principle is: riboflavin is because of knot
Structure characteristic can be embedded in the nucleic acid of virus, under ultraviolet light irradiation, excited the transfer of its electronics, aoxidized the guanine on nucleic acid
Residue, viral nucleic acid are modified and are damaged, and cannot be replicated and be repaired again, to achieve the effect that inactivation of viruses, and core
Flavine is safe drug, without toxic side effect, without filtering out after addition processing.In the granted product of existing foreign countries, only
Riboflavin photochemical method is virus inactivated processing to blood platelet, and individual equipment once can only at most handle two treatments lists
Position.
