The aim of this study is to investigate whether the activity of inducing immune response of glycyrrhetinic acid (GA) could be enhanced after GA was encapsulated with liposome. Three hundred and fifty 14-day-old chickens were randomly assigned to 7 groups and vaccinated with Newcastle disease (ND) vaccine. Simultaneously, the chickens in experimental groups were injected with the glycyrrhetinic acid...
The purpose of this research is to study the effect of sulfated lentinan (sLNT) on immune effect of Newcastle disease (ND) vaccine. In immune response test, 14-day-old chickens were vaccinated with ND vaccine then grouped respectively to inject three sLNTs at two doses, once a day for three successive days, taking non-sulfated lentinan (LNT) as the control. The changes of serum antibody titer and...
In order to validate the immune-enhancement efficacy of compound Chinese herbal medicinal ingredients (cCHMIs), made with astragalus polysaccharide (APS), epimedium polysaccharide (EPS), propolis flavone (PF) and ginsenosides (GS), as immune potentiator or vaccine adjuvants for rabbits, the effects of two cCHMIs on rabbit lymphocyte proliferation and IFN-γ and IL-10 mRNA expression of T lymphocyte...
Two compound Chinese herbal medicinal ingredients (cCHMIs) were prepared, respectively, with epimedium polysaccharide plus propolis flavone (cCHMIs 1) and astragalus polysaccharide plus ginsenoside (cCHMIs 2). In animal immune experiment, Newcastle disease vaccine was mixed, respectively, with two cCHMIs and IL-2 to vaccinate 15-day-old chicken in experimental groups. On days 7, 14, 21 and 28 after...
In order to compare the adjuvant activity of compound Chinese herbal medicinal ingredients (cCHMIs) and filtrate best prescription and dose, two initial screened cCHMIs were prepared and mixed with Newcastle disease (ND) vaccine respectively at three doses to vaccinate 17-day-old chickens, taking the non-adjuvant and oil adjuvant vaccines as controls. On day 7, 14, 21, 28, 35 and 42 after vaccination,...
