[A method of studying the aggregative function of thrombocytes].

Area of Science:

• Hematology
• Clinical Chemistry
• Biomedical Engineering

Background:

• Platelet aggregation is a critical process in hemostasis and thrombosis.
• Accurate measurement of platelet aggregation is essential for diagnosing and managing cardiovascular diseases.
• Existing photometric methods may have limitations in sensitivity and accuracy.

Purpose of the Study:

• To develop and validate an improved photometric technique for assessing platelet aggregation function.
• To enhance the accuracy and sensitivity of platelet aggregation measurements.
• To evaluate the utility of the new method in clinical settings.

Main Methods:

• A novel photometric procedure using a rotating cuvette in a photometer.
• Blood plasma enriched with platelets was stirred atraumatically using an air hole.
• Cuvette rotation at 40-60 r.p.m. prevented platelet sedimentation and aggregation.
• The method was tested on 18 normal subjects and 18 coronary patients.

Main Results:

• The developed photometric technique demonstrated improved accuracy in platelet aggregation assessment.
• Enhanced sensitivity was observed in measuring platelet aggregation function.
• The study successfully differentiated aggregation patterns between normal and coronary patients.

Conclusions:

• The novel photometric method offers a more accurate and sensitive approach to evaluating platelet aggregation.
• This technique holds promise for improved diagnostics and monitoring of conditions involving platelet dysfunction.
• Further research can explore its application in a wider range of thrombotic and hemostatic disorders.
