A major issue concerning the protocols of heavy metal cytotoxicity tests with PC12 cells was the hypothesis that serum in the culture medium might sequester the metal, thus altering the results obtained. However, serum withdrawal impairs the viability of PC12 cells themselves, thus impeding...
Polymorphonuclear (PMN) cells play a key role in innate immunity, due to their ability to produce reactive oxidants such as superoxide (O2–) and hydrogen peroxide (H2O2), and to release antimicrobial proteins and peptides stored in their lysosomal granules. In the present study, the effects of...
A battery of in vitro methods has been developed for the prediction of acute oral toxicity, to reduce the number of animals used for this purpose. However, the results of these tests correlate more closely with lethal serum concentrations than with lethal doses. To address this issue, we have...
