Oregano-oil antagonist lipopolysaccharide (LPS) induced toxicity in pre- and post-hatch chick embryo
The modulating effects of a series of arginine analogues and related nitric oxide synthase inhibitors against the toxicity of sulfur mustard (HD) in primary cultures of chick embryo forebrain neurons were examined. In addition to the previously identified protective compounds, D- and L-nitroarginine methyl ester, eight additional arginine analogues were shown to have significant, concentration-...
Concentrations of the synthetic polymer polyriboinosinic.polyribocytidylic acid that produced no detectable toxicity in normal L cells produced marked cytotoxicity in L cells treated with interferon. This increase in the susceptibility of cells to the toxicity of the polymer was also observed in human cells and secondary mouse embryo cells treated with homologous interferons before exposure to ...
background: in this feasibility study, a mechanically loaded in-vitro tissue culture model of joint morphogenesis using the isolated lower extremity of the 8 day old chick embryo was developed to assess the effects of mechanical loading on joint morphogenesis. methods: the developed in-vitro system allows controlled flexion and extension of the chick embryonic knee with a range of motion of 20 ...
Methanol induces developmental toxicity in rats and mice producing exencephaly, cleft palate, cervical skeletal defects, reduced body weight, and increased embryo/fetal death. Exposure to methanol in whole embryo culture also induces developmental retardation, dysmorphogenesis, and embryo lethality. In the present study, cultured rat and mouse embryos were exposed to methanol and subsequently o...
