查询词典 phosphatidylcholine

It was found that theintrduction of polar phosphatidylcholine to LLA chains had largely changed thehydrophilicity of the synthesized polymers. And from the research ofendothelioid cell (ECV304) compatibility and adhesion of blood platelet, wefound that the cells adhesion of ECV304 on the films of PLLA-PC-PLLA lagedcomparing to PLLA, but then could proliferate and cover the films in total,PLLA-PC-PLLA, the same as PLLA are not cytotoxicity and ECV304 canattach and proliferate on them, and PLLA-PC-PLLA can reduce the adhesion ofblood platelet.
