    This study outlines screening methods to detect chemical immunotoxicity, including organ analysis and function tests. These assessments help understand immune system impacts and chemical mechanisms.

    Area of Science:

    • Toxicology
    • Immunology
    • Pharmacology

    Background:

    • Assessing chemical effects on the immune system is crucial for safety.
    • Screening procedures are needed to identify potential immunotoxic compounds early.

    Purpose of the Study:

    • To discuss parameters for detecting immunotoxic effects.
    • To present functional tests for assessing immune response in rats.
    • To provide examples of immunomodulatory compounds.

    Main Methods:

    • Screening parameters include organ growth, weight, histology, hematology, and immunoglobulin levels (ELISA).
    • Functional tests assess cell-mediated immunity, humoral immunity, and macrophage phagocytosis.
    • These methods are applied when screening indicates potential immunotoxicity.

    Main Results:

    • The study details a comprehensive approach to immunotoxicity assessment.
    • Functional tests provide insight into the mechanism of action of chemicals.
    • Examples illustrate compounds that suppress or stimulate immune responses.

    Conclusions:

    • A multi-faceted approach combining screening and functional tests is effective for evaluating immunotoxicity.
    • Functional assessment is vital for understanding the significance of observed effects.
    • Early immune system development testing offers advantages in chemical safety evaluation.
