The present study was conducted to assess the toxicity of nanosized silver particles (Ag-15nm, 30nm and 55nm) in rat alveolar macrophages. For toxicity evaluations, cellular morphology, mitochondrial function (MTT assay), membrane leakage (LDH assay) and reactive oxygen species generation (ROS) were assessed after a 24h under control and exposed conditions. The morphological appearance of control and exposed cells were observed by an inverted, phase contrast microscope and the uptake of nanoparticles was observed using the CytoViva Ultra Resolution Imaging (URI) system. Morphological images captured at 100x magnification demonstrated that nanoparticle-exposed cells at higher doses became abnormal in size, and most …

The present study was conducted to determine the half-life, assess the toxicity, and passive protection efficacy of purified immunoglobulin G (IgG) from Anthrax Vaccine Adsorbed (AVA) vaccinated human donors. Half-life determinations were calculated from the reportable values obtained using the anti-PA ELISA assay and the Centers for Disease Control's (CDC) "ELISA for Windows" software. For toxicity evaluations animals were observed clinical for one hour post administration and for 14-days post-treatment. The protection efficacy was determined based upon the mortality results from a lethal Bacillus anthracis aerosol challenge. While no protection was achieved in this delayed exposure scenario, the study yielded …
