| abstract | PURPOSE: To provide a blood purification membrane and blood purifier excellent in the comparability with a living body by using a permeable membrane consisting chiefly of modified cellulose and/or cellulose ester wherein the hydrogen atoms of its hydroxyl group are substituted with a specified functional group. n CONSTITUTION: The hydrogen atoms of at least part of hydroxyl groups of cellulose and/or cellulose ester are substituted with a functional group represented by the formula I (wherein R 1 and R 2 are the same or different and alkyl group having 1-5 hydrogen or carbon atoms and R 3 and R 4 are the same or different and hydrogen atom or methyl group). At this time, not less than 0.3% of all of the hydroxyl groups of the cellulose are substituted therewith. The use of a selective permeable membrane consisting chiefly of this modified cellulose as a blood purification membrane brings about improved compatibility with a living body such as controlling a temporary decrease in the number of leukocytes. n COPYRIGHT: (C)1990,JPO&Japio |
