Objective To investigate behavioral and endocrinal changes following the conflict-related stress. Method Male SpragueDawley rats were exposed to stressors using Vogel conflict test. Body weight and behavioral responses in open field test were investigated during the whole procedure. Serum corticosterone level was analyzed using immunoassay. Results Compared with the control, the rats of the 1-week, 2-week and 4-week stressed group showed significantly decreased body weight. There was increasing tendency or significant difference in locomotion between the 1 -week, 2-week and 4-week stressed group and their control. And the hormone levels for the stressed animal were reliably high. Conclusions The increased locomotion, and high corticosterone level and reduced body weight in stress animal,was consistent with the features of anxiety-like disorders. Furthermore, the behavioral and endocrine changes produced by conflict-related stress could maintain a long time. The conflictrelated stress paradigm may be used as psychological stress animal mode in the future.

Enramycin is a polypeptide antibiotic and new, safe animal feed additive. A new purification process was developed, based on pre-purification by macroporous resin and refining by reversed phase chromatography. AB-8 macroporous resin was used for the pre-purification process of enramycin, with an elution buffer of 0.012 mol/L aqueous HCl solution-methanol (50: 50, V/V). Then, enramycin a and enramycin b were separated effectively by C18 reversed phase chromatography, with a elution buffer of 0.05 mol/L aqueous KH2PO4 solution-acetonitrile (70: 30, V/V, pH 4.5). The purities of enramycin a and enramycin b were up to 98.5% and 98.0%, respectively. The yield reached 29.2%. This study would provide a useful reference for the preparation of enramycin a and enramycin b with a high purity.

Antithrombin III (AT III) is the most important anti-clotting substance. Recombinant human antithrombin III (rhAT III) expressed in transgenic goat milk attracts more and more attention. Develop an effective purification route for rhAT III is vital to its industrial production. An efficient purification method was developed for the rapid purification of rhAT III by isoelectric precipitation and heparin affinity chromatography. First, casein was effectively removed by isoelectric precipitation. rhAT III was further purified by heparin affinity chromatography. In the process of heparin affinity chromatography, the effects of pH and temperature on the stability of rhAT III were studied, and the effects of operating conditions, elution gradient, flow rate and sample loaded, on the purification efficiency were also studied. Under the optimized conditions, the protein recovery of rhAT III was about 90% with purity over 99%, while its activity recovery was about 50%. Such a purification process is very simple and effective, and it would provide a valuable reference for the further scaling-up of industrial production.
