The purpose of this study was to compare the relative cytotoxicity of amalgams and to determine whether their toxicity depends upon composition and aging time, by means of a rapid and sensitive in vitro cell culture test. Zinc-containing amalgams showed higher cytotoxicity than did any other amalgams.

AbstractThe most characteristic property of microglia is their swift activation in response to neuronal stress and their capacity for site‐directed phagocytosis. The transformation of microglia into intrinsic brain macrophages appears to be under strict control and takes place if neuronal and/or terminal degeneration occurs in response to nerve lesion.

AbstractHuman exposure to nanoparticles is inevitable as nanoparticles become more widely used and, as a result, nanotoxicology research is now gaining attention. However, while the number of nanoparticle types and applications continues to increase, studies to characterize their effects after exposure and to address their potential toxicity are few in

Journal of Ethnopharmacology, 1989
An attempt to summarise the phytochemical composition of the betel quid, formation of N-nitrosation products during chewing, results of carcinogenicity and mutagenicity studies and the relationship between betel chewing and submucous fibrosis have been made from presently available literature.

Current Opinion in Biotechnology, 1992
Cytotoxic proteins, which enter eukaryotic cells and catalytically inactivate protein synthesis, are being increasingly studied using a combination of molecular biology, cell biology and structural approaches. The creation of genetically engineered fusions with alternative cell-binding ligands paves the way for tailor-made, cell-type-specific killing ...

Endeavour, 1980
Abstract The life of animals can be sustained only if the cellular environment can be closely controlled. Elaborate processes have, therefore, been evolved to detect and eliminate foreign material in the body, including tumour cells. An understanding of these processes is of great medical importance.

Sensitivity of cytotoxic T cells to T-cell mediated cytotoxicity
Nature, 1974LYMPHOID cells sensitised against alloantigens can lyse in vitro target cells bearing these alloantigens1,2. In most of the experimental systems using in vivo sensitised cells, T cells (thymus-dependent lymphocytes) are both necessary3 and sufficient4,5 for induction of target cell lysis.

Calreticulin in Cytotoxic Lymphocyte-Mediated Cytotoxicity
2003New functions are implicated for calreticulin, based on its release from cytotoxic NK and T cells. Calreticulin is the only one of six “KDEL” (Lys-Asp-Glu-Leu carboxy terminal) endoplasmic reticulum chaperone proteins present in cytotoxic granules of these lymphocytes.

SummaryWhen mouse spleen cell were cultured in vitro without the deliberate addition of any stimulating cells, T cell‐mediated cytotoxicity was generated which could be detected by lysis of 51Cr‐labelled syngeneic and allogeneic tumour target cells.
