It is reported ' The intersection of reporter and the intersection of reporter and a sail, king of DeFu, Li) set up, Feng Recently, the national natural science fund project of what is the blood station of Anhui Province Red Cross, Hefei centre, heat of Chinese University of Science and Technology cooperate with energy engineering department and finish scientifically " The blood is kept for a long time - -Freeze the erythrocyte dry and replies the optimization research of water " The market passes expert qualification in Hefei. If this technology can apply to clinic, will solve the problem that the blood is kept for a long time fundamentally. From 2001, it has been launched " the blood is saved for a long time " together that the blood station of the centre of Red Cross, Hefei united heat science and energy engineering department of Chinese University of Science and Technology - -Freeze the erythrocyte dry and replies the optimization research of water " Project, until erythrocyte freeze do and reply water, optimize some problems that store in in the research at present, through setting up theory model and optimizing the experiment, has made multiple achievements. First, studied injury function in the course of protecting pharmaceuticals and adding, lowering the temperature, freezing dry, replying water, eluting of the erythrocyte systematically. Go through, test, find four the intersection of volume and law protect pharmaceutical, add until four,etc. permeate, press, change law, wash, damage to the erythrocyte minimumly repeatedly many times. Second, proposed systematically the erythrocyte is frozen, done penetrating damage and solution in the course, draw the conclusion that polymer is protected pharmaceutical has higher glass temperature, find under different speed of lowering the temperature, freeze the erythrocyte, do the difference of the rate of recovery after replying water. Third, utilize in afterbirth of Carleson that revises the ice crystal turn into the model, finds the greater permeability to water of red cell membrane is, then the erythrocyte dehydrates the faster, solution is damaged and strengthened. Find the membrane that the erythrocyte damages is turned into mechanism while replying water at the same time. Fourth, the more differently one replies aqueous solution, replies the water temperature and replies the influence on freezing and doing rate of recovery of the erythrocyte of the water speed, measure and reply the water temperature better in over 34 �� result, find the erythrocyte leads to the fact while replying water that the phenomenon that the volume increase, reduce first and then increases appears because of absorbing water and permeating and pressing and changing. According to the study on above-mentioned injury function, the expert adopts different optimization experiments, freeze protection pharmaceutical done and fill a prescription and lower the temperature, freeze dry and replying water and protects pharmaceuticals and elute the procedure after optimizing the erythrocyte, have developed a set of erythrocytes to freeze, do the method to keep. The connoisseur thinks, this project is set up and optimized the erythrocyte to freeze, do the technical parameter which reply water; Choose respect to the intersection of erythrocyte and influence and procedure done to freeze in penetrating research, optimization, the intersection of drop in the temperature and the intersection of speed,etc. and factor to protect pharmaceutical of damage, have obvious innovative and advance, reach and lead competence at home. Propose testing in the body as soon as possible, realize the transformation of scientific and technical result.
