Abstract : 5 - fu liposome was prepared by the reverse evaporating method . then the entrapment reached 43 . 31 % by freeze - thawing 5 - fu liposome several times . the centrifugal accelaration experiment and the measurement of potential proved that the stability of the liposome could be ameliorated 文摘:采用反相蒸发法制备5 -氟尿嘧啶脂质体制剂.结合冻融法，可使5 -氟尿嘧啶的包封率达( 45 . 31 0 . 2085 ) % .离心加速实验和电位的测定进一步验证了冻融法可使脂质体稳定性提高
