A battery of potential alternatives to the Draize test: uridine uptake inhibition, morphological cytotoxicity, macrophage chemotaxis and exfoliative cytology.
Four assays that may serve as components of a battery of alternatives to the conventional Draize test were described. The exfoliative cytology assay is a refinement of the Draize test that may provide a more sensitive and more objective end-point. The macrophage migration assay addresses the inflammatory aspects of the physiological response to irritation. The uridine uptake inhibition assay uses a quantitative, reversible end-point to detect the short-term action of agents on cell membranes and cell phosphorylative potential. Finally, the cytological assay serves as a rapid, easily performed general indicator of cytotoxic action. The two latter assays have been demonstrated to correlate very well with Draize test results and with each other for a wide range of test agents.
