【摘要】 【目的】观察叶下珠复方Ⅱ号体内抗鸭乙型肝炎病毒(DHBV)的作用。【方法】采用聚合酶链反应(PCR)法筛选DHBV-DNA阳性的先天感染鸭30只,随机分为5组:病毒对照组,叶下珠复方Ⅱ号高、中、低剂量组(剂量分别为33.6、18.6、8.4 g.kg-1.d-1)、拉米夫定组(剂量为20 mg.kg-1.d-1)。各组于用药前后分别采用荧光定量PCR法检测血清DHBV-DNA含量变化。【结果】在给药第7、14、21、28天及停药后第5天叶下珠复方Ⅱ号高、中剂量组鸭血清DHBV-DNA含量显著降低,与给药前和病毒对照组比较差异均有显著性意义(P<0.05或P<0.01)。【结论】叶下珠复方Ⅱ号具有一定的抑制DHBV复制作用。更多还原

【Abstract】 Objective To evaluate the in-vivo effect of Compound Phyllanthus urinaria Ⅱ(CPU Ⅱ) on duck hepatitis B virus(DHBV).Methods Thirty ducks with congenital infection of DHBV,which were DHBV-DNA positive confirmed by polymerase chain reaction(PCR),were randomly divided into 5 groups: DHBV control group,high-,middle-,and low-dosage CPU Ⅱgroups(in the dose of 33.6,18.6 and 8.4 g-1·d-1,respectively),and Lamivudine group(20 mg·kg-1·d-1).The serum DHBV-DNA level of all ducks was detected by quantity real-time fluorescence PCR before and after medication.Results On the 7th,14th,21st,and 28th day of medication and on the 5th day of suspension of medication,the serum DHBV-DNA level in both of the high-and middle-dosage CPU Ⅱ groups was obviously lower than that before medication and than that in the DHBV control group(P<0.05 or P<0.01).Conclusion CPU Ⅱ has certain inhibitory effect on DHBV replication.更多还原
