    This study reviews granulocyte and macrophage functions, detailing methods to assess their activity. It highlights how surgical practices and malnutrition can impair these crucial immune cell functions.

    Area of Science:

    • Immunology
    • Cellular Biology
    • Surgical Science

    Background:

    • Granulocytes and macrophages are key immune cells involved in pathogen defense.
    • Assessing their function is critical for understanding immune status.
    • Several clinical conditions are known to affect immune cell performance.

    Purpose of the Study:

    • To present granulocyte physiology and methods for assessing immune cell functions.
    • To describe techniques for evaluating adherence, migration, phagocytosis, bacterial killing, and metabolic activity.
    • To discuss the impact of common surgical practices and malnutrition on immune cell function.

    Main Methods:

    • Review of techniques for assessing granulocyte adherence, migration, phagocytosis, bacterial killing, and metabolic activity.

  • Description of methods to evaluate reticuloendothelial system activity.
  • In vivo measurement of macrophage phagocytic and metabolic function.

    • Main Results:

    • Phagocytic function of immune cells can be decreased in various clinical scenarios.
    • Post-open heart surgery, colloid infusion, and immunosuppressive drug therapy can impair immune cell function.
    • Malnutrition, including starvation, obesity, and hypertriglyceridemia, negatively affects granulocyte function.

    Conclusions:

    • Immune cell function, particularly phagocytosis, is vulnerable to common surgical interventions and nutritional states.
    • Understanding these impacts is essential for managing patients in surgical and critical care settings.
    • Further research into mitigating these functional impairments is warranted.
