Artificial blood ready for clinical demonstration test

摘要

Achievements of R&D on artificial blood is approaching to operational use. Artificial blood is naturally inferior to living human blood, but it is able to store as reserve for long time and can transfuse regardless blood type, So practical application is desired eagerly in near future. Blood is composed of blood plasma by 55%, and rest is cells including blood capsule. More than 90% of blood plasma is water and contain protein such as albumin, globulin, inorganic salt which control OSmotic pressure hormone, fat, enzymes, etc. Cells is composed of 96% of blood corpuscle and 3% of white corpuscle. Artificial blood, however, is not able to contain all of these components due to cost problem.
