The sleeve size implants the thing to be able to cause the guinea pig and the monkey produces the treatment hemophilia one kind of protein. The animals will not present the hemorrhage barrier, therefore whether the research to hasn’t implanted the thing to reverse the hemophilia directly to carry on the test. But the blood sample analysis demonstrated that implants the thing to cause on one kind of animal body’s natural protein to transform the certain amount the useful active shape, is called as Factor VIIa, it has used at present in the treatment hemophilia. Researchers for Maryland Dr. Uniformed Services university medical school’s Harvey Pollard and his colleague. The hemophilia is because lacks one kind to press the blood to congeal the protein (i.e. Factor VIII) to create. Doctor may input this kind of protein to the patient to carry on the treatment. But has 15% patients to produce the immune body, prevents to input in vivo protein activeness. These patients may change input Factor VIIa, but this medicine price is expensive, moreover the protein will decompose rapidly. Implants the thing to be possible to avoid the above two kind of situations, and will not cause the body to produce the immune body. Implants the thing is one kind includes can VII transform Factor the Factor VII material the porous room. The researchers put in three in monkey’s abdomen to implant the thing, the result are implanting the thing to take out carry on observe the preceding month, monkey in vivo have produced Factor VIIa. The scientist hoped that in one to two year carries on the human body experiment.
