This experiment was conducted to investigate dietary putrescine effects on broiler performance. Treatments were 6 levels of putrescine (0, 0.01, 0.02, 0.03, 0.04 & 0.05 %) added to a basal diet and fed to 4-32 day old broilers. The weekly growth performance was recorded, and ileal digesta and small intestine samples were collected at the end of the 2nd and 3rd week of age. At 21 d, body weight ...

this study was conducted to evaluate the effects of exogenous polyamines, isopropyl ester, 2, 4-d and naphthalene acetamide application on yield and quality of date palm of ‘kabkab’ cultivar. the inflorescences sprayed with 2, 4-d isopropylester (0, 10, and 20 mg l-1), naphthalene acetamide (0, 80, and 120 mg l-1), putrescence and spermidine (0, 0.1, and 1.0 mm), three or six weeks after pollin...

To study the antitumor activity of alkaloid extracted from Oxytropis ochrocephala and its possible mechanism, we observed the effect of alkaloid on tumor weight and expression of PCNA and p53 in mice bearing H(22) hepatocellular carcinoma by means of immunohistochemistry SP method. After treatment with alkaloid from Oxytropis ochrocephala, the results showed that alkaloid administration (25 and...

In order to assess chicken T cell-mediated responses after immune stress, 200 two-week-old chickens were randomly divided into control group(C) and treatment groups (T1 and T2). The live I-type of Newcastle disease vaccine (ND) was taken as the source of immunological stress. The chickens in group (T2) were injected with overdose of live I-type Newcastle disease vaccine. After vaccination, the ...

Despite the worldwide eradication of smallpox in 1979, the potential bioterrorism threat from variola virus and the ongoing use of vaccinia virus (VACV) as a vector for vaccine development argue for continued research on VACV. In China, the VACV Tiantan strain (TT) was used in the smallpox eradication campaign. Its progeny strain is currently being used to develop a human immunodeficiency virus...
