②The HA valence of PNDV in 0.5% cock RBC is higher than that in 1% cock RBC by 1~2 dilution grades,and HA valence of PPV in 0.5% cock RBC is higher than that in 1% cock RBC by 5 dilution grades;
Abstract ND La Sota N79 strain and EDS-76 H931 strain were inoculated into chicken embryos and duck embryos for virus reproduction. Virus was collected when the hemagglutination valence≥1: 1280and ≥1: 10000 respectively. Collected virus inactivated with Formalin and mixed with certain proportions of Tuwn-80, Span-80, Aluminum Stearate and Leucoil, and then blended to produce NDEDS-76 Oil-adjnvent combined vaccine.
The results showed the average gramatomic ratios of C:H:N:O was 10:12:1:3.There were two valence states of sulfur (S and S), andS occupied a dominant position, there was only one valence state for nitrogen In the IR spectra,the maximum absorbance lay between 1619-- 163cm-1, which revealed that the melanin were irregular high--polymers consisting of indole structure.

Results showed that dietary copper levels(8 mg/kg)significantly increased with performance, antibody valence to NDV in serum and CuZn-SOD activity at the early stage , ANAE+% of lymphocyte and ether extract apparent deposit rate through the whole period (P<0.01) ;
The RHDV-whn-2 shows high hemagglutinin valence of 1:640, but whn-1 and whn-3 show low hemagglutinin valence of 1:5,1:10 respectively. Limpid precipitation manifest can be seen during identification of 3 RHDV isolations by AGP and countercurrent immunoelectrophoresis, as well virion with a diameter of about 30nm can be observed in the electron microscope.
This study aimed to describe the distribution of water-arsenic (As) valence states and its relationship to areas with endemic arsenism in the Datong basin.
This led us to conclude that the fraction of each water-arsenic valence state should be studied when determining the arsenic content of drinking water.
We have regularly observed the increase of perentageof B lymphatic cells and exhaustion of HI mother's body antibody to ninety chicken of one to thirty-six born days under this experment.Semetime we used Ⅱ vacune drops putting to the nose of sixty chicken of different born days and observed repeatdly every 5dats the valence of HI antibody. The result showes: The increase of percentage of B lymphatic cells, circulated in the blood is in direct proportion with HI valence of antibody, persisted tim...
Mouse myeloma SP_2/0 cell and hybridoma 7E8 cell, without adaptation in low serum concentration medium, can be well cultivated in serum-free medium I (SFM-I) . The maximun viable cell density of 2.57×10~6 cells/ml in the case of SP_2/0 cell and 1.88×10~6 cells/mlin the case of 7E8 cell were attained. An equal of 84hrsmaitaining time of the viable cell density above 1×10~6 cells / ml was achieved when either SP_2 / 0 cell or 7E8 cell was cultured in SFM-I . These data were better than those achieved in SFM-Ⅱ...
Purified the against toxoplasma McAb (3C1), immunized rabbit and prepared polyclonal against-Id antibody (Abz). Use of M-206 adjuvant prepared vaccine of against-Id. The pig and mice -ere immunized with the vaccine at dose of 31.75mg/pig and 2.5mg/mice respectively. The antibody valence was 1:4 after immune 7 days, and in 28 days was 1:64 (IHA). Challenge with toxoplasma virulent strain (GTS) to pig and mice according to 107 and 103. Immunized pig without obvious clinical reaction, but control group a...
