Abstract:

Study of radix Arnebiae on newcastle disease virus inhibition. SPF chicken embryo culture and Hemagglutination test were used to evaluate the inhibitory effect of Chinese tradition medicine radix Arnebiae on Newcastle disease virus. Test a total of 4 groups, first groups inoculated virus allantoic fluid and radix Arnebiae mixture, HA was 0. The second group of inoculation of the virus allantoic fluid with amantadine hydrochloride mixture, HA was 4 log2. Article III group inoculated virus allantoic fluid and normal saline solution, HA was 8 log2. Article IV group not inoculated virus allantoic fluid, not to the drug, HA was 0. The group I and III group had extremely significant difference (P<0.01 ), the group II and III group had significant difference (P<0.05 ). The results showed that the radix Arnebiae had no side-effect on SPF chicken embryo. Synchronously inoculating SPF chicken embryo with the radix Arnebiae and virus allantoic fluid could completely inhibited the reproduction of Newcastle disease virus in SPF chicken embryo.
