Recombinant porcine alpha interferon and application thereof in preparing medicines for treating Porcine cytomegalovirus (PCMV)

The invention discloses a recombinant porcine alpha interferon, prepared by the following methods: A1, synthesizing an artificially modified porcine alpha interferon; A2, constructing a recombinant eukaryotic expression vector pGAPZ alpha-IFN alpha; and A3, highly expressing IFN alpha by an eukaryotic cell yeast expression system. The invention is characterized by taking a supernatant to purifying the porcine alpha interferon which is cultured by a lot of engineering bacteria and expressed with a chromatography column, then collecting a target protein eluate, filtering through a 0.22 mum microfiltration membrane, then determining the activity by cytopathic inhibition, and calculating the potency unit according to 50% pathology; wherein the cell used for determination is Madin-Darby bovine kidney (MDBK), and vesicular stomatitis virus (VSV) is used for attacking the virus. According to the invention, the recombinant porcine alpha interferon obtained by purification is applied in controlling PCMV, and experiments prove that the recombinant porcine alpha interferon has obvious protection effect on PCMV infected cells. The route of administration of the porcine alpha interferon is injection or mucous membrane administration, and the dosage form comprises injection or nasal drops.

Application of Platycodon grandiflorum total saponins in the treatment and prevention of mycoplasma pneumoniae infectious diseases

ActiveCN102274264AInfectious Disease Prevention and ControlAvoid Overshooting ProblemsAntibacterial agentsRespiratory disorderBALB/cTherapeutic effect
The invention relates to application of a platycodon root total saponin to medicaments for treating and preventing mycoplasma pneumoniae infectious diseases, and relates to application of platycodon root total saponin to medicaments. The platycodon root total saponin is used as the active ingredient of the medicaments for treating and preventing the mycoplasma pneumoniae infectious diseases, and is a composition of one or more of saponins of platycogenic acid, polygalic acid, platycogenic acid and platycogenic acid A lactone. The platycodon root total saponin has the effect of resisting mycoplasma pneumoniae; in-vitro experiments indicate that a minimal inhibitory concentration (MIC) value of resisting mycoplasma pneumoniae (MP) is between 16 and 64 mu g / ml, and the minimal bactericidal concentration (MBC) is between 64 to 128 mu g / ml; and in-vivo experiments indicate that after 8 mg / Kg and 16 mg / Kg of platycodon root total saponins are subjected to intragastric administration on BALB / C mice subjected to MP injection by nasal dropping for 10 days, the pathological injury of lungs of the mice can be relieved obviously, and the immunologic function of organisms is regulated, so the platycodon root total saponin has a treatment effect on the MP infection.
