Background:

Leucocyte (white blood cell) migration is crucial for immune responses.
Accurate measurement of cell migration is essential for understanding immune function and disease.
Existing methods for quantifying leucocyte migration can be time-consuming and labor-intensive.

Purpose of the Study:

To develop and validate a semi-automatic system for measuring leucocyte migration within micropore filters.
To assess the efficiency and utility of the developed system for immunological research.
To apply the system to investigate leucocyte responses to specific stimuli.

Main Methods:

Development of a semi-automatic system for measuring leucocyte migration distance.
Digital display and on-line analysis of migration data using a digital computer.
Experimental application to determine dose-response relationships of leucocytes to casein.
Assessment of cellular response variations to Staphylococcus aureus and casein in normal human subjects.

Main Results:

The semi-automatic system significantly reduces measurement time compared to manual methods.
Digital and computer-based analysis allows for precise quantification of leucocyte migration.
Dose-response relationships between leucocytes and casein were successfully established.
Variations in leucocyte responses to Staphylococcus aureus and casein were observed in normal individuals.

Conclusions:

The developed semi-automatic system enhances the efficiency and accuracy of leucocyte migration measurement.
This technology facilitates the full utilization of the micropore filter method for immunological studies.
The system provides a valuable tool for investigating immune cell behavior and responses to pathogens and inflammatory agents.
