    Left ventricle puncture is the preferred rat blood collection method for platelet aggregation studies. Isolated rat platelets remain aggregable after storage, enabling objective analysis of platelet function, especially in arterial hypertension.

    Area of Science:

    • Cardiovascular Research
    • Hematology
    • Animal Models

    Background:

    • Accurate blood collection is crucial for reliable platelet studies.
    • Platelet aggregation is a key indicator of cardiovascular health.
    • Rat models are widely used in hypertension research.

    Purpose of the Study:

    • To compare three rat blood collection methods for platelet aggregation studies.
    • To detail a method for isolating and preserving rat platelets.
    • To introduce a mathematical model for analyzing platelet aggregation rates.

    Main Methods:

    • Comparison of blood collection via decapitation, carotid artery catheterization, and left ventricle puncture.
    • Detailed protocol for isolating washed platelets from rat blood.

  • Application of an exponential approximation model (A = A0exp(-αt)) to aggregation curves.

    • Main Results:

    • Left ventricle puncture demonstrated superiority for platelet aggregation studies.
    • Isolated rat platelets retained aggregability after several hours of storage at 20°C.
    • The exponential model provided objective data analysis for platelet functional activity.

    Conclusions:

    • Left ventricle puncture is recommended for rat blood collection in platelet aggregation research.
    • Rat platelets exhibit stable aggregation properties under specific storage conditions.
    • The proposed model facilitates objective assessment of platelet function, particularly in models of arterial hypertension.
