title: Preliminary studies on the validity of in vitro measurement of drug toxicity using HeLa cells. II. Drug toxicity in the MIT-24 system compared with mouse and human lethal dosage of 52 drugs.
abstract: By a comparison of the 50% inhibitory concentration to HeLa cells in the microtitre Metabolic Inhibition Test supplemented by microscopy of cells after 24 h incubation (the MIT-24 test), of 52 drugs with their mouse i.v. LD50 and available approximate human lethal dosage, 7 were found to have a human LD considerably lower than HeLa IC50, indicating a lethal action to specialized functions of the human body not found in vitro, while 39 were found to have a gross similarity between the human LD and HeLa IC50.
