    Area of Science:

    • Environmental Toxicology
    • Computational Biology

    Background:

    • In vitro assays are crucial for assessing chemical toxicity and mutagenicity.
    • Analyzing large datasets from these assays can be complex and time-consuming.

    Purpose of the Study:

    • To describe a suite of computer programs for the Tektronix 4050 graphic system.
    • To facilitate the analysis of in vitro test data in environmental toxicology.

    Main Methods:

    • Programs designed for cell number, viability, ATP, protein, and DNA synthesis.
    • Modules for calculating mutagenicity parameters like cloning efficiency and mutation frequency.
    • Data storage on magnetic tape with defined file structures and experimental identification.

    Main Results:

    • The programs can compute key toxicological and mutagenic endpoints from raw experimental data.
    • Statistical analysis and frequency distribution subprograms are included.
    • Demonstrated applicability using Chinese hamster ovary cells exposed to cadmium chloride and a mutagen.

    Conclusions:

    • The developed programs offer a comprehensive solution for analyzing diverse in vitro toxicology and mutagenicity data.
    • These computational tools enhance the efficiency and accuracy of environmental risk assessment.
