ABSTRACT

0.998 8).The minimum detection limit were 0.1～0.4 mg?L-1.The average recovery rates were no less than 96%(RSD≤7.19%).There were significant difference among the concentration of Ara-C and Ara-U in plasma,cerebrospinal fluid and testicular tissue.Ara-C in plasma hadn't been determined in low-dose group and medium-dose group except for Ara-U.CONCLUSIONS: The method is simple,rapid,accurate and reproducible for plasma concentration monitoring and pharmacokinetic study of Ara-C and Ara-U.
