    Area of Science:

    • Cardiovascular Science
    • Vascular Biology
    • Microscopy Techniques

    Context:

    • Hypertension and atherosclerosis are significant risk factors for cardiovascular diseases.
    • Assessing vascular wall permeability is crucial for understanding disease progression.
    • Existing methods for permeability assessment may have limitations.

    Purpose:

    • To describe and validate a new technique for assaying aortic wall permeability.
    • To utilize fluorescent microscopy with trypan blue for quantitative permeability measurements.
    • To apply this technique to a rabbit model of experimental hypertension and atherosclerosis.

    Summary:

    • Fluorescent microscopy and trypan blue staining were employed to evaluate aortic wall permeability.
    • Dye permeation into the vascular wall was quantified using photometry and graphic data recording.
    • The described method successfully enabled the exploration of aortic wall permeability in rabbits with induced hypertension and atherosclerosis.

    Impact:

    • Provides a novel, quantitative method for assessing aortic wall permeability.
    • Facilitates research into the mechanisms of hypertension and atherosclerosis.
    • Offers a valuable tool for preclinical studies of vascular diseases.
