Abstract
Objective:To study the anti-duck Hepatitis B virus(DHBV) action of protoporphyrin disodium(PPN).Methods: Longyan ducks with congenital infection of HBV were used as the animal model and the each group of ducks was given the drug with the doses 20 mg·kg~(-1)·d~(-1) for 10 successive days.DHBV-DNA in serum was detected by dot-hybridization test before treatment,5 days and 10 days after treatment,the pathological changes of the duck liver were also examined by HE staining.Results: After giving medication with PPN for 5 days and for 10 days,the optic density value of DHBV-DNA in ducks serum were obviously lower than that before treated(1.36±0.26,1.05±0.28 VS 2.04±0.05,1.90±0.31),there were remarkable difference(P0.01,P0.05).Spotty hepatocyte necroses in treatment group was improved more obviously than that in model group.Conclusion: PPN can protect duck liver against inflammation by the inhibition of DHBV.
