查询词典 prefilter

The concentrations of TNF-αand IL-10 in peripheral blood increased significantly after CVVH.The concentration of NO decreased significantly after CVVH.There was no TNF-αin ultrafiltrate;IL-10 was detected little and NO was detected much in ultrafiltate.Compared with prefilter,the concentration of TNF-αin postfilter blood decreased significantly at 1h of CVVH and increased at the end of CVVH. Compared with prefilter,the concentration of NO in postfilter blood decreased significantly at 1h ,12h and the end of CVVH.

CVVH治疗后患者血清TNF-α、IL-10浓度与治疗前相比明显升高，而NO浓度与治疗前相比显著下降，超滤液中未能检测出TNF-α，仅检测到少量IL-10，但NO在超滤液中浓度较高；CVVH治疗1h时，静脉端血清TNF-α浓度明显低于动脉端，CVVH治疗结束时，静脉端血清TNF-α浓度明显高于动脉端；CVVH治疗1h，12h和结束时，静脉端血清NO浓度均明显低于动脉端。
