Viruses of the Russian tick-borne encephalitis complex have been reported to proliferate in chicken embryo tissue culture of Maitland type (17, 18). Recent studies on louping-ill virus have demonstrated it, s cytopathogenic effect in monolayer cultures of HeLa cells (16), Detroit 6 cells (22), and pig kidney cells (23). No eytopathogenicity has been shown with RSSE virus in skin-muscle tissue c...

aflatoxins are toxic compounds which are produced by aspergillus flavus and a. parasiticus. these toxins can be transmitted into the animal body via contaminated feed. when these toxins enter the animal body, they can penetrate into different tissues. one of the most important tissues which can be influenced by aflatoxin is the mammary gland. milk protein is one the most important factors in de...

Two different viruses were isolated from bovine embryonic cell cultures after two subcultures from the primary cells. One virus was identified as parainfluenza type 2 simian virus 5 (SV-5), and the other was identified as infectious bovine rhinotracheitis virus. Six months later, stock cultures of pig kidney (PK-15) cells were found to be contaminated with SV-5 virus. We believe that the source...

background: lactoferrin (lf) is a glycoprotein, a member of the transferrin family.from ten known mechanisms of anti-cancer chemoperotecive compounds, lf alone, has six of these functions and inhibits cancer. in this study, the effect of lactoferrin purified from bovine colostrum was studied as an anti-cancer agent on esophageal cancer cell line. materials and methods: bovine colostrum were col...

introduction : deproteinized bovine bone mineral (bio-oss) is a xenogenic bone substitute, widely used in maxillofacial bone regeneration. the aim of this in vitro study was to investigate its influence on the growth behavior of human osteosarcoma cell line, saos-2 culture, and compare it with the physiologic dose of dexamethasone, an inductive factor for osteoblasts. materials and methods: hum...

phytohemagglutinin (pha) is a lectin, obtained from the red kidney bean that binds to the membranes of t-cells and stimulates metabolic activity, cell division, etc. the object of this research was the comparison between self made pha (indigenous) and imported commercial one, following conventional and high resolution cell synchronization technique (hrcs) .from each blood sample of healthy indi...
